I have a friend that always says "innovation happens at the speed of trust". Ever since GPT3, that quote comes to mind over and over.
Verification has a high cost and trust is the main way to lower that cost. I don't see how one can build trust in LLMs. While they are extremely articulate in both code and natural language, they will also happily go down fractal rabbit holes and show behavior I would consider malicious in a person.
So get another LLM to do it. Judging is considerably easier [For LLMs] than writing something from scratch, so LLM judges will always have that edge in accuracy. Equivalently, I also like getting them to write tons of tests to build trust in correct behavior.
> Judging is considerably easier than writing something from scratch
I don't agree with this at all. Writing new code is trivially easy, to do a full in depth review takes significantly more brain power. You have to fully ascertain and insert yourself into someone elses thought process. Thats way more work than utilizing your own thought process.
Sorry, I should have been more specific. I meant LLMs are more reliable and accurate at judging than at generating from scratch.
They basically achieve over 80% agreement with human evaluators [1]. This level of agreement is similar to the consensus rate between two human evaluators, making LLM-as-a-judge a scalable and reliable proxy for human judgment.
LLMs will not have the context behind the lines of code in the CR.
Sure there's no bug with how the logic is defined in the CR or even in the context of the project, ti maybe won't throw an exception.
But the LLM won't know that the query is iterating over an unindexed field in the DB with the table in prod having 10s of millions of rows. The LLM won't know that even though the code says the button should be red and the comments say the button should be red, the corporate style guide says red should be a very specific hex code that it isn't.
Mmmhmm. And you think this "growing up" doesn't have biases to lie in circumstances where it matters? Consider politics. Politics matter. It's inconceivable that a magic algorithm would lie to us about various political concerns, right? Right...?
A magic algorithm lying to us about anything would be extremely valuable to liars. Do you think it's possible that liars are guiding the direction of these magic algorithms?
they've been saying that for three years and the performance improvement has been asymptotic (logarithmic) for a decade, if you've been following the state of the art that long.
We never can have total trust in LLM output, but we can certainly sanitize it and limit it's destructive range. Just like we sanitize user input and defend with pentests and hide secrets in dot files, we will eventually resolve to "best practices" and some "SOC-AI compliance" standard down the road.
It's just too useful to ignore, and trust is always built, brick by brick. Let's not forget humans are far from reliable anyway. Just like with driving cars, I imagine producing less buggy code (along predefined roads) will soon outpace humans. Then it is just blocking and tackling to improve complexity.
I check AI output for hallucinations and issues as I don’t fully trust it to work, but we also do PRs with humans to have another set of eyes check because humans also make mistakes.
For the soft sciences and arts I’m not sure how to validate anything from AI but for software and hard sciences I don’t see why test suites wouldn’t continue serving their same purpose
Famously, "it's easier to write code than to read it". That goes for humans. So why did we automate the easy part and move the effort over to the hard part?
If we need a human in the loop to check every row of code for the deep logic errors... then we could just get the human to write it no?
> As the use of AC spread rapidly with other companies deploying their own systems, the Edison Electric Light Company claimed in early 1888 that high voltages used in an alternating current system were hazardous, and that the design was inferior to, and infringed on the patents behind, their direct current system.

Not surprising at all. He was a minor player in the Current Wars compared to his primary benefactor, George Westinghouse. His image was rehabilitated first by Serbian-Americans and then by webcomic artists and Redditors, who turned him into a secular saint.
Most of what people think they know about Tesla is not actually true if you examine the historical record. But software engineering as a discipline demands business villains and craftsman heroes, and so Edison and Tesla were warped to fit those roles even though in real life there is only evidence of cordial interactions.
I use it to mean that the more people trust each other, the quicker things get done. Maybe the statement can be rephrased as "progress happens at the speed of trust" to avoid the specific scientific connotation.
Importantly, there are many business processes today that are already limited by lack of trust. That's not necessarily a bad thing either - checks and balances exist for a reason. But it does strongly suggest that increasing "productivity" by dumping more inputs into the process is counter-productive to the throughput of the overall system.
You're not catching on. It's not the trust in the technology, it's the trust between people. Consider business dealings between entities that do not have high trust - everything becomes mediated through lawyers and nothing happens without a contract. Slow and expensive. Handshake deals and promises kept move things along a lot faster and without the expense of hammering out legal arrangements.
LLM leads to distrust between people. From TFA, That concept is Trust - It underpins everything about how a group of engineers function and interact with each other in all technical contexts. When you discuss a project architecture you are trusting your team has experience and viewpoints to back up their assertions.
I use it to mean that the more people trust each other, the quicker things get done.
True not only in innovation, but in business settings.
I don't think there's anyone who works in any business long enough who doesn't have problems getting their job done simply because someone else with a key part of the project doesn't trust that you know what you're doing.
How much trust was there in electricity, flight and radioactivity when we discovered them?
Not much.
Plenty of people were against electricity when it started becoming common. They were terrified of lamps, doorbells, telephones, or anything else with an electric wire. If they were compelled to use these things (like for their job) they would often wear heavy gloves to protect themselves. It is very occasionally mentioned in novels from the late 1800's.
(Edit: If you'd like to see this played out visually, watch the early episodes of Miss Fisher's Murder Mysteries on ABC [.oz])
There are still people afraid of electricity today. There is no shortage of information on the (ironically enough) internet about how to shield your home from the harmful effects of electrical wires, both in the house and utility lines.
Flight? I dunno about back then, but today there's plenty of people who are afraid to fly. If you live in Las Vegas for a while, you start to notice private train cars occasionally parked on the siding near the north outlet mall. These belong to celebrities who are afraid to fly, but have to go to Vegas for work.
Radioactivity? There was a plethora of radioactive hysteria in books, magazines, comics, television, movies, and radio. It's not hard to find.
I bumped into this at work but not in the way you might expect. My colleague and I were under some pressure to show progress and decided to rush merging a pretty significant refactor I'd been working on. It was a draft PR but we merged it for momentum's sake. The next week some bugs popped up in an untested area of the code.
As we were debugging, my colleague revealed his assumption that I'd used AI to write it, and expressed frustration at trying to understand something AI generated after the fact.
But I hadn't used AI for this. Sure, yes I do use AI to write code. But this code I'd written by hand and with careful deliberate thought to the overall design. The bugs didn't stem from some fundamental flaw in the refactor, they were little oversights in adjusting existing code to a modified API.
This actually ended up being a trust building experience over all because my colleague and I got to talk about the tension explicitly. It ended up being a pretty gentle encounter with the power of what's happening right now. In hindsight I'm glad it worked out this way, I could imagine in a different work environment, something like this could have been more messy.
I don't understand the premise. If I trust someone to write good code, I learned to trust them because their code works well, not because I have a theory of mind for them that "produces good code" a priori.
If someone uses an LLM and produces bug-free code, I'll trust them. If someone uses an LLM and produces buggy code, I won't trust them. How is this different from when they were only using their brain to produce the code?
Essentially the premise is that in medium trust environments like very large teams or low trust environments like an open source project.
LLMs make it very difficult to make an immediate snap judgement about the quality of the dev that submitted the patch based solely on the code itself.
In the absence of being able to ascertain the type of person you are dealing with you have to fall back too "no trust" and review everything with a very fine tooth comb. Essentially there are no longer any safe "review shortcuts" and that can be painful in places that relied on those markers to grease the wheels so to speak.
Obviously if you are in an existing competent high trust team then this problem does not apply and most likely seems completely foreign as a concept.
> LLMs make it very difficult to make an immediate snap judgement about the quality [...]
That's the core of the issue. It's time to say goodbye to heuristics like "the blog post is written in eloquent, grammatical English, hence the point its author is trying to make must be true" or "the code is idiomatic and following all code styles, hence it must be modeling the world with high fidelity".
Maybe that's not the worst thing in the world. I feel like it often made people complacent.
> Maybe that's not the worst thing in the world. I feel like it often made people complacent.
For sure, in some ways perhaps reverting to a low trust environment might improve quality in that it now forces harsher/more in depth reviews.
That however doesn't make the requirement less exhausting for people previously relying heavily on those markers to speed things up.
Will be very interesting to see how the industry standardizes around this. Right now it's a bit of the wild west. Maybe people in ten years will look back at this post and think "what do you mean you judged people based on the code itself that's ridiculous"
I think you're unfair to the heuristics people use in your framing here.
You said "hence the point its author is trying to make must be true" and "hence it must be modeling the world with high fidelity".
But it's more like "hence the author is likely competent and likely put in a reasonable effort."
When those assumptions hold, putting in a very deep review is less likely to pay off. Maybe you are right that people have been too complacent to begin with, I don't know, but I don't think you've framed it fairly.
Yes! This is part of why I bristle at such reductive takes, we can use more nuance thinking about what we are gaining and what we are losing and how to deal with it.
It's not about fashion, it's about diligence and consideration. Code formatting is totally different from say clothing fashion. Social fashions are often about being novel or surprising which is the opposite of how good code is written. Code should be as standard, clear and unsurprising as is reasonably possible. If someone is writing code in a way that's deliberately unconventional or overly fancy that's a strong signal that it isn't very good.
When someone follows standard conventions it means that they A) have a baseline level of knowledge to know about them, and B) care to write the code in a clear and approachable way for others.
> If someone is writing code in a way that's deliberately unconventional or overly fancy that's a strong signal that it isn't very good.
“unconventional” or “fancy” is in the eye of the beholder. Whose conventions are we talking about? Code is bad when it doesn't look the way you want it to? How convenient. I may find code hard to read because it's formatted “conventionally”, but I wouldn't be so entitled as to call it bad just because of that.
Where are these mythical languages? I think the word you're looking for is syntax, which is entirely different. Conventions are how code is structured and expected to be read. Very few languages actually enforce or even suggest conventions, hence the many style guides. It's a standout feature of Go to have a format style, and people still don't agree with it.
And it's kinda moot when you can always override conventions. It's more accurate to say a team decides on the conventions of a language.
No, they're absolutely correct that it's critical in professional and open source environments. Code is written once but read hundreds or thousands of times.
If every rando hire goes in and has a completely different style and formatting -- and then other people come in and rewrite parts in their own style -- code rapidly goes to shit.
It doesn't matter what the style is, as long as there is one and it's enforced.
> No, they're absolutely correct that it's critical in professional and open source environments. Code is written once but read hundreds or thousands of times
What you're saying is reasonable, but that's not what they said at all. They said there's one way to write cleanly and that's "Standard conventions", whatever that means. Yes, conventions so standard that I've read 10 conflicting books on what they are.
There is no agreed upon definition of "readable code". A team can have a style guide, which is great to follow, but that is just formalizing the personal preference of the people working on a project. It's not anymore divine than the opinion of a "rando."
No, you misunderstood what they said. And I misspoke a little, too.
While it's true that in principle it doesn't matter what style you choose as long as there is one, in practice languages are just communities of people, and every community develops norms and standards. More recent languages often just pick a style and bake it in.
This is a good thing, because again, code is read 1000x more times than it's written. It saves everyone time and effort to just develop a typical style.
And yeah, the code might run no matter how you indent it, but it's not correct, any more than you going to a restaurant and licking the plates.
> its about the quality of the code, not the quality of the dev. you might think it's related, but it's not.
I could not disagree more. The quality of the dev will always matter, and has as much to do with what code makes it into a project as the LLM that generated it.
An experienced dev will have more finely tuned evaluation skills and will accept code from an LLM accordingly.
An inexperienced or “low quality” dev may not even know what the ideal/correct solution looks like, and may be submitting code that they do not fully understand. This is especially tricky because they may still end up submitting high quality code, but not because they were capable of evaluating it as such.
You could make the argument that it shouldn’t matter who submits the code if the code is evaluated purely on its quality/correctness, but I’ve never worked in a team that doesn’t account for who the person is behind the code. If its the grizzled veteran known for rarely making mistakes, the review might look a bit different from a review for the intern’s code.
> An experienced dev will have more finely tuned evaluation skills and will accept code from an LLM accordingly.
An inexperienced or “low quality” dev may not even know what the ideal/correct solution looks like, and may be submitting code that they do not fully understand. This is especially tricky because they may still end up submitting high quality code, but not because they were capable of evaluating it as such.
That may be true, but the proxy for assessing the quality of the dev is the code. No one is standing over you as you code your contribution to ensure you are making the correct, pragmatic decisions. They are assessing the code you produce to determine the quality of your decisions, and over time, your reputation as a dev is made up of the assessments of the code you produced.
The point is that an LLM in no way changes this. If a dev uses an LLM in a non-pragmatic way that produces bad code, it will erode trust in them. The LLM is a tool, but trust still factors in to how the dev uses the tool.
> That may be true, but the proxy for assessing the quality of the dev is the code.
Yes, the quality of the dev is a measure of the quality of the code they produce, but once a certain baseline has been established, the quality of the dev is now known independent of the code they may yet produce. i.e. if you were to make a prediction about the quality of code produced by a "high quality" dev vs. a "low quality" dev, you'd likely find that the high quality dev tends to produce high quality code more often.
So now you have a certain degree of knowledge even before you've seen the code. In practice, this becomes a factor on every dev team I've worked around.
Adding an LLM to the mix changes that assessment fundamentally.
> The point is that an LLM in no way changes this.
I think the LLM by definition changes this in numerous ways that can't be avoided. i.e. the code that was previously a proxy for "dev quality" could now fall into multiple categories:
1. Good code written by the dev (a good indicator of dev quality if they're consistently good over time)
2. Good code written by the LLM and accepted by the dev because they are experienced and recognize the code to be good
3. Good code written by the LLM and accepted by the dev because it works, but not necessarily because the dev knew it was good (no longer a good indicator of dev quality)
4. Bad code written by the LLM
5. Bad code written by the dev
#2 and #3 is where things get messy. Good code may now come into existence without it being an indicator of dev quality. It is now necessary to assess whether or not the LLM code was accepted because the dev recognized it was good code, or because the dev got things to work and essentially got lucky.
It may be true that you're still evaluating the code at the end of the day, but what you learn from that evaluation has changed. You can no longer evaluate the quality of a dev by the quality of the code they commit unless you have other ways to independently assess them beyond the code itself.
If you continued to assess dev quality without taking this into consideration, it seems likely that those assessments would become less accurate over time as more "low quality" devs produce high quality code - not because of their own skills, but because of the ongoing improvements to LLMs. That high quality code is no longer a trustworthy indicator of dev quality.
> If a dev uses an LLM in a non-pragmatic way that produces bad code, it will erode trust in them. The LLM is a tool, but trust still factors in to how the dev uses the tool.
Yes, of course. But the issue is not that a good dev might erode trust by using the LLM poorly. The issue is that inexperienced devs will make it increasingly difficult to use the same heuristics to assess dev quality across the board.
In my experience they very much are related. High quality devs are far more likely to output high quality working code. They test, they validate, they think, ultimately they care.
In that case that you are reviewing a patch from someone you have limited experience with, it previously was feasible to infer the quality of the dev from the context of the patch itself and the surrounding context by which it was submitted.
LLMs make that judgement far far more difficult and when you can not make a snap judgement you have to revert your review style to very low trust in depth review.
No more greasing the wheels to expedite a process.
Spot on, there are so many little things that we as humans use as subtle verification steps to decide how much scrutiny various things require. LLMs are not necessarily the death of that concept but they do make it far far harder.
It's easy to get overconfident and not test the LLM's code enough when it worked fine for a handful of times in a row, and then you miss something.
The problem is often really one of miscommunication, the task may be clear to the person working on it, but with frequent context resets it's hard to make sure the LLM also knows what the whole picture is and they tend to make dumb assumptions when there's ambiguity.
The thing that 4o does with deep research where it asks for additional info before it does anything should be standard for any code generation too tbh, it would prevent a mountain of issues.
It isn’t, and that is a sign of a bad dev you shouldn’t trust.
LLMs are a tool, just like any number of tools that are used by developers in modern software development. If a dev doesn’t use the tool properly, don’t trust them. If they do, trust them. The way to assess if they use it properly is in the code they produce.
Your premise is just fundamentally flawed. Before LLMs, the proof of a quality dev was in the pudding. After LLMs, the proof of a quality dev remains in the pudding.
> Your premise is just fundamentally flawed. Before LLMs, the proof of a quality dev was in the pudding. After LLMs, the proof of a quality dev remains in the pudding.
Indeed it does, however what the "proof" is has changed. In terms of sitting down and doing a full, deep review, tracing every path validating every line etc. Then for sure, nothing has changed.
However, at least in my experience, pre LLM those reviews were not EVERY CASE there were many times I elided parts of a deep review because i saw markers in the code that to me showed competency, care etc. With those markers there are certain failure conditions that can be deemed very unlikely to exist and therefore the checks can be skipped. Is that ALWAYS the correct assumption? Absolutely not but the more experienced you are the less false positives you get.
LLMs make those markers MUCH harder to spot, so you have to fall back to doing a FULL indepth review no matter what. You have to eat ALL the pudding so to speak.
For people that relied on maybe tasting a bit of the pudding then assuming based on the taste the rest of the pudding probably tastes the same its rather jarring and exhausting to now have to eat all of it all the time.
> However, at least in my experience, pre LLM those reviews were not EVERY CASE there were many times I elided parts of a deep review because i saw markers in the code that to me showed competency, care etc.
That was never proof in the first place.
If anything, someone basing their trust in a submission on anything other than the code itself is far more concerning and trust-damaging to me than if the submitter has used an LLM.
I mean, it's not necessarily HARD proof but it has been a reliable enough way to figure out which corners to cut. You can of course say that no corners should ever be cut and while that is true in an ideal sense. In the real world things always get fuzzy.
Maybe the death of cutting corners is a good thing overall for output quality. Its certainly exhausting on the people tasked with doing the reviews however.
I don't know about that. Cutting corners will never die.
Ultimately I don't think the heuristics would change all that much, though. If every time you review a person's PR, almost everything is great, they are either not using AI or they are vetting what the AI writes themselves, so you can trust them as you did before. It may just take some more PRs until that's apparent. Those who submit unvetted slop will have to fix a lot of things, and you can crank up the heat on them until they do better, if they can. (The "if they can" is what I'm most worried about.)
Of course you are, but it's sort of like how people are responsible their Tesla driving on autopilot, which then suddenly swerves into a wall and disengages two seconds before impact. The process forces you to make mistakes you wouldn't normally ever do or even consider a possibility.
To add to devs and Teslas, you have journalists using LLMs writing summaries, lawyers using LLMs writing dispositions, doctors using LLMs writing their patient entries, and law enforcement using LLMs writing their forensics report.
All of these make mistakes (there are documented incidents).
And yes, we can counter with "the journalists are dumb for not verifying", "the lawyers are dumb for not checking", etc., but we should also be open for the fact that these are intelligent and professional people who make mistakes because they were mislead by those who sell LLMs.
In the past someone might have been physically healthy and strong enough to physically shovel dirt all day long
Nowadays this is rarer because we use an excavator instead. Yes, a professional dirt mover is more productive with an excavator than a shovel, but is likely not as physically fit as someone spending their days moving dirt with a shovel
I think it will be similar with AI. It is absolutely going to offload a lot of people's thinking into the LLMs and their "do it by hand" muscles will atrophy. For knowledge workers, that's our brain
I know this was a similar concern with search engines and Stack Overflow, so I am trying to temper my concern here as best I can. But I can't shake the feeling that LLMs provide a way for people to offload their thinking and go on autopilot a lot more easily than Search ever did
I'm not saying that we were better off when we had to move dirt by hand either. I'm just saying there was a physical tradeoff when people moved out of the fields and into offices. I suspect there will be a cognitive tradeoff now that we are moving away from researching solutions to problems and towards asking the AI to give us solutions to problems
Because when people use LLMs, they are getting the tool to do the work for them, not using the tool to do the work. LLMs are not calculators, nor are they the internet.
A good rule of thumb is to simply reject any work that has had involvement of an LLM, and ignore any communication written by an LLM (even for EFL speakers, I'd much rather have your "bad" English than whatever ChatGPT says for you).
I suspect that as the serious problems with LLMs become ever more apparent, this will become standard policy across the board. Certainly I hope so.
Well, no, a good rule of thumb is to expect people to write good code, no matter how they do it. Why would you mandate what tool they can use to do it?
Because it pertains to the quality of the output - I can't validate every line of code, or test every edge case. So if I need a certain level of quality, I have to verify the process of producing it.
This is standard for any activity where accuracy / safety is paramount - you validate the process. Hence things like maintenance logs for airplanes.
> So if I need a certain level of quality, I have to verify the process of producing it
Precisely this, and this is hardly a unique to software requirement. Process audits are everywhere in engineering. Previously you could infer the process of producing some code by simply reading the patch and that generally would tell you quite a bit about the author itself. Using advanced and niche concepts with imply a solid process with experience backing it. Which would then imply that certain contextual bugs are unlikely so you skip looking for them.
My premise in the blog is basically that "Well now I have go do a full review no matter what the code itself tells me about the author."
> My premise in the blog is basically that "Well now I have go do a full review no matter what the code itself tells me about the author."
Which IMO is the correct approach - or alternatively, if you do actually trust the author, you shouldn't care if they used LLMs or not because you'd trust them to check the LLM output too.
> Because when people use LLMs, they are getting the tool to do the work for them, not using the tool to do the work.
You can say that for pretty much any sort of automation or anything that makes things easier for humans. I'm pretty sure people were saying that about doing math by hand around when calculators became mainstream too.
I’m not seeing a lot of discussion about verification or a stronger quality control process anywhere in the comments here. Is that some kind of unsolvable problem for software? I think if the standard of practice is to use author reputation as a substitute for a robust quality control process, then I wouldn’t be confident that the current practice is much better than AI code-babel.
I think the main issue is people using LLMs to do things that they don't know how to do themselves. There's actually a similar problem with calculators, it's just a much smaller one: if you never learn how to add or multiply numbers by hand and use calculators for everything all the time, you may sometimes make absurd mistakes like tapping 44 * 3 instead of 44 * 37 and not bat an eye when your calculator tells you the result is a whole order of magnitude less than what you should have expected. Because you don't really understand how it works. You haven't developed the intuition.
There's nothing wrong with using LLMs to save time doing trivial stuff you know how to do yourself and can check very easily. The problem is that (very lazy) people are using them to do stuff they are themselves not competent at. They can't check, they won't learn, and the LLM is essentially their skill ceiling. This is very bad: what plus-value are you supposed to bring over something you don't understand? AGI won't have to improve from the current baseline to surpass humans if we're just going to drag ourselves down to its level.
You’re being unfairly downvoted. There is a plague of well-groomed incoherency in half of the business emails I receive today. You can often tell that the author, without wrestling with the text to figure out what they want to say, is a kind of stochastic parrot.
This is okay for platitudes, but for emails that really matter, having this messy watercolor kind of writing totally destroys the clarity of the text and confuses everyone.
To your point, I’ve asked everyone on my team to refrain from writing words (not code) with ChatGPT or other tools, because the LLM invariably leads to more complicated output than the author just badly, but authentically, trying to express themselves in the text.
I find the idea of using LLMs for emails confusing.
Surely it's less work to put the words you want to say into an email, rather than craft a prompt to get the LLM to say what you want to say, and iterate until the LLM actually says it?
My own opinion, which is admittedly too harsh, is that they don't really know what they want to say. That is, the prompt they write is very short, along the lines of `ask when this will be done` or `schedule a followup`, and give the LLM output a cursory review before copy-pasting it.
Yep, I have come to really dislike LLMs for documentation as it just reads wrong to me and I find so often misses the point entirely. There is so much nuance tied up in documentation and much of it is in what is NOT said as much as what is said.
The LLMs struggle with both but REALLY struggle with figuring out what NOT to say.
I wonder if this is to a large degree also because when we communicate with humans, we take cues from more than just the text. The personality of the author will project into the text they write, and assuming you know this person at least a little bit, these nuances will give you extra information.
That's sort of the problem isn't it? There is no real way to know so we sort of just have to assume every bit of work is involving LLMs now so we have to take a lot closer look at everything
>Because when people use LLMs, they are getting the tool to do the work for them, not using the tool to do the work.
What? How on god's green earth could you even pretend to know how all people are using these tools?
> LLMs are not calculators, nor are they the internet.
Umm, okay? How does that make them less useful?
I'm going to give you a concrete example of something I just did and let you try and do whatever mental gymnastics you have to do to tell me it wasn't useful:
Medicare requires all new patients receiving home health treatment go through a 100+ question long form. This form changes yearly, and it's my job to implement the form into our existing EMR. Well, part of that is creating a printable version. Guess what I did? I uploaded the entire pdf to Claude and asked it to create a print-friendly template using Cottle as the templating language in C#. It generated the 30 page print preview in a minute. And it took me about 10 more minutes to clean up.
> I suspect that as the serious problems with LLMs become ever more apparent, this will become standard policy across the board. Certainly I hope so.
The irony is that they're getting better by the day. That's not to say people don't use them for the wrong applications, but the idea that this tech is going to be banned is absurd.
> A good rule of thumb is to simply reject any work that has had involvement of an LLM
Do you have any idea how ridiculous this sounds to people who actually use the tools? Are you going to be able to hunt down the single React component in which I asked it to convert the MUI styles to tailwind? How could you possibly know? You can't.
> If someone uses an LLM and produces bug-free code, I'll trust them.
Only because you already trust them to know that the code is indeed bug-free. Some cases are simple and straightforward -- this routine returns a desired value or it doesn't. Other situations are much more complex in anticipating the ways in which it might interact with other parts of the system, edge cases that are not obvious, etc. Writing code that is "bug free" in that situation requires the writer of the code to understand the implications of the code, and if the dev doesn't understand exactly what the code does because it was written by an LLM, then they won't be able to understand the implications of the code. It then falls to the reviewer to understand the implications of the code -- increasing their workload. That was the premise.
If you have a long standing, effective heuristic that “people with excellent, professional writing are more accurate and reliable than people with sloppy spelling and punctuation” then the appearance of a semi-infinite group of ‘people’ writing well presented, convincingly worded articles which nonetheless are riddled with misinformation, hidden logical flaws, and inconsistencies, you’re gonna end up trusting everyone a lot less.
It’s like if someone started bricking up tunnel entrances and painting ultra realistic versions of the classic Road Runner tunnel painting on them, all over the place. You’d have to stop and poke every underpass with a stick just to be sure.
Yeah, now you need to be able to demonstrate verbal fluency. The problem is, that inherently means a loss of “trusted anonymous” communication, which is particularly damaging to the fiber of the internet.
Precisely, in the age where it is very difficult to ascertain the type or quality of skills you are interacting with say in a patch review or otherwise you frankly have to "judge" someone and fallback to suspicion and full verification.
"A bit inconvenient" might be the understatement of the year. If information requires say, 2x the time to validate, the utility of the internet is halved.
What you're seeing now is people who once thought and proclaimed these tools as useless now have to start to walk back their claims with stuff like this.
It does amaze me that the people who don't use these tools seem to have the most to say about them.
For what it's worth I do actually use the tools albeit incredibly intentionally and sparingly.
I see quite a few workflows and tasks that they can be a value add on, mostly outside of the hotpath of actual code generation but still quite enticing. So much so in fact I'm working on my own local agentic tool with some self hosted ollama models. I like to think that i am at least somewhat in the know on the capabilities and failure points of the latest LLM tooling.
That however doesn't change my thoughts on trying to ascertain if code submitted to me deserves a full indepth review or if I can maybe cut a few corners here and there.
> That however doesn't change my thoughts on trying to ascertain if code submitted to me deserves a full indepth review or if I can maybe cut a few corners here and there.
How would you even know? Seriously, if I use Chatgpt to generate a one-off function for a feature I'm working on that searches all classes for one that inherits a specific interface and attribute, are you saying you'd be able to spot the difference?
And what does it even matter it works?
What if I use Bolt to generate a quick screen for a PoC? Or use Claude to create a print-preview with CSS of a 30 page Medicare form? Or converting a component's styles MUI to tailwind? What if all these things are correct?
This whole OS repos will ban LLM-generated code is a bit absurd.
> or what it's worth I do actually use the tools albeit incredibly intentionally and sparingly.
How sparingly? Enough to see how it's constantly improving?
> How would you even know? Seriously, if I use Chatgpt to generate a one-off function for a feature I'm working on that searches all classes for one that inherits a specific interface and attribute, are you saying you'd be able to spot the difference?
I don't know, thats the problem. As a result, because I can't know I have to now do full in depth reviews no matter what. Which is the "judging" I tongue in cheek talk about in the blog.
> How sparingly? Enough to see how it's constantly improving?
Nearly daily, to be honest I have not noticed too much improvement year over year in regards to how they fail. They still break in the exact same dumb ways now as they did before. Sure they might generate correct syntactic code reliably now and it might even work. But they still consistently fail to grok the underlying reasoning for things existing.
But I am writing my own versions of these agentic systems to use for some rote menial stuff.
So you werent doing in depth reviews before? Are these people you know? And now you just don't trust them because they include a tool on their workflow?
> It does amaze me that the people who don't use these tools seem to have the most to say about them.
You're kidding, right? Most people who don't use the tools and write about it are responding to the ongoing hype train -- a specific article, a specific claim, or an idea that seems to be gaining acceptance or to have gone unquestioned among LLM boosters.
I recently watched a talk by Andrei Karpathy. So much in it begged for a response. Google Glass was "all the rage" in 2013? Please. "Reading text is laborious and not fun. Looking at images is fun." You can't be serious.
Someone recently shared on HN a blog post explaining why the author doesn't use LLMs. The justification for the post? "People keep asking me."
Being asked if I'm kidding by the person comparing Google glasses to machine learning algorithms is pretty funny ngl.
And the "I don't use these tools and never will" sentiment is rampant in the tech community right now. So yes, I am serious.
Youre not talking about the blog post that completely ignored agentless uses are you? The one that came to the conclusion LLMs arent useful despite only using a subset of its features?
> Being asked if I'm kidding by the person comparing Google glasses to machine learning algorithms is pretty funny ngl.
I didn't draw the comparison. Karpathy, one of the most prominent LLM proponents on the planet -- the guy who invented the term 'vibe-coding' -- drew the comparison.[1]
> And the "I don't use these tools and never will" sentiment is rampant in the tech community right now. So yes, I am serious.
I think you misunderstood my comment -- or my comment just wasn't clear enough: I quoted the line "It does amaze me that the people who don't use these tools seem to have the most to say about them." and then I asked "You're kidding, right?" In other words, "you can't seriously believe that the nay-sayers 'always have the most to say.'" It's a ridiculous claim. Just about every naysayer 'think piece' -- whether or not it's garbage -- is responding to an overwhelming tidal wave of pro-LLM commentary and press coverage.
> Youre not talking about the blog post that completely ignored agentless uses are you? The one that came to the conclusion LLMs arent useful despite only using a subset of its features?
I'm referring to this one[2]. It's awful, smug, self-important, sanctimonious nonsense.
I'm so confused as to why you took that so literally. I didn't literally mean that the nay-sayers are producing more words than the evangelists. It was a hyperbolic expression. And I wasn't JUST talking about the blog posts. I'm talking about ALL comments about it.
Sure, that's fair, though tone is difficult both to communicate and to detect in writing. I have just the literal meaning of your words. And I'm a very literal-minded person. :)
> And the "I don't use these tools and never will" sentiment is rampant in the tech community right now
So is the "These tools are game changers and are going to make all work obsolete soon" sentiment
Don't start pretending that AI boosters aren't everywhere in tech right now
I think the major difference I'm noticing is that many of the Boosters are not people who write any code. They are executives, managers, product owners, team leads, etc. Former Engineers maybe but very often not actively writing software daily
> I think the major difference I'm noticing is that many of the Boosters are not people who write any code.
Plenty of current, working engineers who frequent and comment on Hacker News say they use LLMs and find them useful/'game changers,' I think.
Regardless, I think I agree overall: the key distinction I see is between people who like to read and write programs and people who just want to make some specific product. The former group generally treat LLMs as an unwelcome intrusion into the work they love and value. The latter generally welcome LLMs because the people selling them promise, in essence, that with LLMs you can skip the engineering and just make the product.
I'm part of the former group. I love reading code, thinking about it, and working with it. Meeting-based programming (my term for LLM-assisted programming) sounds like hell on earth to me. I'd rather blow my brains out than continue to work as a software engineer in a world where the LLM-booster dream comes true.
> I'd rather blow my brains out than continue to work as a software engineer in a world where the LLM-booster dream comes true.
I feel the same way
But please don't. I promise I won't either. There is still a place for people like you and me in this world, it's just gonna take a bit more work to find it
> So is the "These tools are game changers and are going to make all work obsolete soon" sentiment
Except we aren't talking about those people, are we? The blog post wans't about that.
> Don't start pretending that AI boosters aren't everywhere in tech right now
PLEASE tell me what I said that made you feel like you need to put words in my mouth. Seriously.
> I think the major difference I'm noticing is that many of the Boosters are not people who write any code
I write code every day. I just asked Claude to convert a Medicare mandated 30 page assessment to a printable version with CSS using Cottle in C# and it did it. I'd love to know why that sort of thing isn't useful.
That is already the case for me. The amount of times I've read "apologies for the oversight, you are absolutely correct" is staggering: 8 or 9 out of 10 times. Meanwhile I constantly see people mindlessly copy paying llm generated code and subsequently furious when it doesn't do what they expected it to do. Which, btw, is the better option: I'd rather have something obviously broken as opposed to something seemingly working.
Are you using the LLM's through a browser chatbot? Because the AI-agents we use with direct code-access aren't very chatty. I'd also argue that they are more capable than a lot of junior programmers, at least around here. We're almost at a point where you can feed the agents short specific tasks, and they will perform them well enough to not really require anything outside of a code review.
That being said, the prediction engine still can't do any real engineering. If you don't specifically task them with using things like Python generators, you're very likely to have a piece of code that eats up a gazillion memory. Which unfortunately don't set them appart from a lot of Python programmers I know, but it is an example of how the LLM's are exactly as bad as you mention. On the positive side, it helps with people actually writing the specification tasks in more detail than just "add feature".
Where AI-agents are the most useful for us is with legacy code that nobody prioritise. We have a data extractor which was written in the previous millennium. It basically uses around two hunded hard-coded coordinates to extact data from a specific type of documents which arrive by fax. It's worked for 30ish years because the documents haven't changed... but it recently did, and it took co-pilot like 30 seconds to correct the coordinates. Something that would've likely taken a human a full day of excruciating boredom.
I have no idea how our industry expect anyone to become experts in the age of vibe coding though.
> Because the AI-agents we use with direct code-access aren't very chatty.
Every time I tell claude code something it did is wrong, or might be wrong, or even just ask a leading question about a potential bug it just wrote, it leads with "You're absolutely correct!" before even invoking any tools.
Maybe you've just become used to ignoring this. I mostly ignore it but it is a bit annoying when I'm trying to use the agent to help
me figure out if the code it wrote is correct, so I ask it some question it should be capable of helping with and it leads with "you're absolutely correct".
I didn't make a proposition that can be correct or not, and it didn't do any work yet to to investigate my question - it feels like it has poisoned its own context by leading with this.
> Where AI-agents are the most useful for us is with legacy code
I’d love to hear more about your workflow and the code base you’re working in. I have access to Amazon Q (which it looks like is using Claude Sonnet 4 behind the scenes) through work, and while I found it very useful for Greenfield projects, I’ve really struggled using it to work on our older code bases. These are all single file 20,000 to 100,000 line C modules with lots of global variables and most of the logic plus 25 years of changes dumped into a few long functions. It’s hard to navigate for a human, but seems to completely overwhelm Q’s context window.
Do other Agents handle this sort of scenario better, or are there tricks to making things more manageable? Obviously re-factoring to break everything up into smaller files and smaller functions would be great, but that’s just the sort of project that I want to be able to use the AI for.
All of this fighting against LLMs is pissing in the wind.
It seems that LLMs, as they work today, make developers more productive. It is possible that they benefit less experienced developers even more than experienced developers.
More productivity, and perhaps very large multiples of productivity, will not be abandoned due roadblocks constructed by those who oppose the technology due to some reason.
Examples of the new productivity tool causing enormous harm (eg: bug that brings down some large service for a considerable amount of time) will not stop the technology if it being considerable productivity.
Working with the technology and mitigating it's weaknesses is the only rational path forward. And those mitigation can't be a set of rules that completely strip the new technology of it's productivity gains. The mitigations have to work with the technology to increase its adoption or they will be worked around.
> It seems that LLMs, as they work today, make developers more productive.
Think this strongly depends on the developer and what they're attempting to accomplish.
In my experience, most people who swear LLMs make them 10x more productive are relatively junior front-end developers or serial startup devs who are constantly greenfielding new apps. These are totally valid use cases, to be clear, but it means a junior front-end dev and a senior embedded C dev tend to talk past each other when they're discussing AI productivity gains.
> Working with the technology and mitigating it's weaknesses is the only rational path forward.
Or just using it more sensibly. As an example: is the idea of an AI "agent" even a good one? The recent incident with Copilot[0] made MS and AI look like a laughingstock. It's possible that trying to let AI autonomously do work just isn't very smart.
As a recent analogy, we can look at blockchain and cryptocurrency. Love it or hate it, it's clear from the success of Coinbase and others that blockchain has found some real, if niche, use cases. But during peak crypto hype, you had people saying stuff like "we're going to track the coffee bean supply chain using blockchain". In 2025 that sounds like an exaggerated joke from Twitter, but in 2020 it was IBM legitimately trying to sell this stuff[1].
It's possible we'll look back and see AI agents, or other current applications of generative AI, as the coffee blockchain of this bubble.
> In my experience, most people who swear LLMs make them 10x more productive are relatively junior front-end developers or serial startup devs who are constantly greenfielding new apps.

I agree with this quite a lot. I also think that those greenfield apps quickly become unmanageable by AI as you need to start applying solutions that are unique/tailored for your objective or you want to start abstracting some functionality into building components and base classes that the AI hasn't seen before.
I find AI very useful to get me to a from beginner to intermediate in codebases and domains that I'm not familiar with but, once I get the familiarity, the next steps I take mostly without AI because I want to do novel things it's never seen before.
But this doesn't mean that the model/human combo is more effective at serving the needs of users! It means "producing more code."
There are no LLMs shipping changesets that delete 2000 lines of code -- that's how you know "making engineers more productive" is a way of talking about how much code is being created...
My wife's company recently hired some contractors and they were touting their productivity with AI by saying how it allowed them (one person) to write 150k lines of code in 3 weeks. They said this without sarcasm. It was funny and scary at the same time that anyone might buy this as a good outcome. Classic lines-of-code metric rearing its ugly head again.
I think you’re arguing against something the author didn’t actually say.
You seem to be claiming that this is a binary, either we will or won’t use llms, but the author is mostly talking about risk mitigation.
By analogy it seems like you’re saying the author is fundamentally against the development of the motor car because they’ve pointed out that some have exploded whereas before, we had horses which didn’t explode, and maybe we should work on making them explode less before we fire up the glue factories.
I didn't see the post as pissing into the wind so much as calling out several caveats of coding with LLMs, especially on teams, and ideas on how to mitigate them.
It is funny (ego) I remember when React was new and I refused to learn it, had I learned it earlier I probably would have entered the market years earlier.
Even now I have this refusal to use GPT where as my coworkers lately have been saying "ChatGPT says" or this code was created by chatGPT idk, for me I take pride writing code myself/not using GPT but I also still use google/stackoverflow which you could say is a slower version of GPT.
this mindset does not work in software. My dad would still be programming with punchcards if he thought this way. instead he using copilot daily writing microservices and isnt some annoying dinosaur
yeah it's pro con, I also hear my coworkers saying "I don't know how it works" or there are methods in the code that don't exist
But anyway I'm at the point in my career where I am not learning to code/can already do it. Sure languages are new/can help there for syntax
edit: other thing I'll add, I can see the throughput thing, it's like a person has never used opensearch before and it's a rabbithole, anything new there's that wall you have to overcome, but it's like we'll get the feature done, but did we really understand how it works... do we need to? Idk. I know this person can barely code but because they use something like chatGPT they're able to crap out walls of code and with tweaking it will work eventually -- I am aware this sounds like gatekeeping from my part
Ultimately personally I don't want to do software professionaly/trying to save/invest enough then get out just because the job part sucks the fun out of development. I've been in it for about 10 years now, should have been plenty of time to save but I'm dumb/too generous.
I think there is healthy skepticism too vs. just jumping on the bandwagon that everyone else is doing and really my problem is just I'm insecure/indecisive, I don't need everyone to accept me especially if I don't need money
Last rant, I will be experimenting with agentic stuff as I do like Jarvis, make my own voice rec model/locally runs.
> While the industry leaping abstractions that came before focused on removing complexity, they did so with the fundamental assertion that the abstraction they created was correct. That is not to say they were perfect, or they never caused bugs or failures. But those events were a failure of the given implementation a departure from what the abstraction was SUPPOSED to do, every mistake, once patched led to a safer more robust system. LLMs by their very fundamental design are a probabilistic prediction engine, they merely approximate correctness for varying amounts of time.
I think what the author misses here is that imperfect, probabilistic agents can build reliable, deterministic systems. No one would trust a garbage collection tool based on how reliable the author was, but rather if it proves it can do what it intends to do after extensive testing.
I can certainly see an erosion of trust in the future, with the result being that test-driven development gains even more momentum. Don't trust, and verify.
It's naive to hope that automatic tests will find all problems. There are several types of problems that are hard to detect automatically: concurrency problems, resource management errors, security vulnerabilities, etc.
An even more important question: who tests the tests themselves? In traditional development, every piece of logic is implemented twice: once in the code and once in the tests. The tests checks the code, and in turn, the code implicitly checks the tests. It's quite common to find that a bug was actually in the tests, not the app code. You can't just blindly trust the tests, and wait until your agent finds a way to replicate a test bug in the code.

Author here: Here I was less talking about the effectiveness of the output of a given tool and more so about the tool itself.
To take your garbage collection example, sure perhaps an agentic system at some point can spin some stuff up and beat it into submission with test harnesses, bug fixes etc.
But, imagine you used the model AS the garbage collector/tool, in that say every sweep you simply dumped the memory of the program into the model and told it to release the unneeded blocks. You would NEVER be able to trust that the model itself correctly identifies the correct memory blocks and no amount of "patching" or "fine tuning" would ever get you there.
With other historical abstractions like say jvm, if the deterministic output, in this case the assembly the jit emits is incorrect that bug is patched and the abstraction will never have that same fault again. not so with LLMs.
To me that distinction is very important when trying to point out previous developer tooling that changed the entire nature of the industry. It's not to say I do not think LLMs will have a profound impact on the way things work in the future. But I do think we are in completely uncharted territory with limited historical precedence to guide us.
> promises that the contributed code is not the product of an LLM but rather original and understood completely.
> require them to be majority hand written.
We should specify the outcome not the process. Expecting the contributor to understand the patch is a good idea.
> Juniors may be encouraged/required to elide LLM-assisted tooling for a period of time during their onboarding.
This is a terrible idea. Onboarding is a lot of random environment setup hitches that LLMs are often really good at. It's also getting up to speed on code and docs and I've got some great text search/summarizing tools to share.
> Onboarding is a lot of random environment setup hitches
Learning how to navigate these hitches is a really important process
If we streamline every bit of difficulty or complexity out of our lives, it seems trivially obvious that we will soon have no idea what to do when we encounter difficulty or complexity. Is that just me thinking that?
> > Onboarding is a lot of random environment setup hitches

> Learning how to navigate these hitches is a really important process
To add to this, a barrier to contribution can reduce low quality/spam contributions. The downside is that a barrier to contribution that's too high reduces all contributions.
There will always be people who know how to handle the complexity we're trying to automate away. If I can't figure out some arcane tax law when filling out my taxes, I ask my accountant, as it's literally their job to know these things.
> There will always be people who know how to handle the complexity we're trying to automate away
This is not a given!
If we automated all accounting, why would anyone still take the time to learn to become an accountant?
Yes, there are sometimes people who are just invested in learning traditional stuff for the sake of it, but is that really what we want to rely on as the fallback when AI fails?
> LLMs … approximate correctness for varying amounts of time. Once that time runs out there is a sharp drop off in model accuracy, it simply cannot continue to offer you an output that even approximates something workable. I have taken to calling this phenomenon the "AI Cliff," as it is very sharp and very sudden
I’ve never heard of this cliff before. Has anyone else experienced this?
I experience it pretty regularly -- once the complexity of the code passes a certain threshold, the LLM can't keep everything in its head and starts thrashing around. Part of my job working with the LLM is to manage the complexity it sees.
And one of the things with current generators is that they tend to make things more complex over time, rather than less. It's always me prompting the LLM to refactor things to make it simpler, or doing the refactoring once it's gotten to complex for the LLM to deal with.
So at least with the current generation of LLMs, it seems rather inevitable that if you just "give LLMs their head" and let them do what they want, eventually they'll create a giant Rube Goldberg mess that you'll have to try to clean up.
ETA: And to the point of the article -- if you're an old salt, you'll be able to recognize when the LLM is taking you out to sea early, and be able to navigate your way back into shallower waters even if you go out a bit too far. If you're a new hand, you'll be out of your depth and lost at sea before you know it's happened.
Imagine that you have your input to the context, 10000 tokens that are 99% correct. Each time the LLM replies it adds 1000 tokens that are 90% correct.
After some back-and-forth of you correcting the LLM, its context window is mostly its own backwash^Woutput. Worse, the error compounds because the 90% that is correct is just correct extrapolation of an argument about incorrect code, and because the LLM ranks more recent tokens as more important.
I reset "work" AI sessions quite frequently, so I didn't see that there. I experienced it though with storytelling. In my storytelling scenario, context and length was important. And the AI at one late point forgot how my characters should behave in the developing situation, and just had them react to it in a very different way. And there was no going back from that. Very weird experience.
I call it context rot. As the context fills up the quality of output erodes with it. The rot gets even worse or progresses faster the more spurious or tangential discussion is in context.
This is also can be made much worse by thinking models, as their CoT is all in context, and if there thoughts really wander it just plants seeds of poison feeding the rot. I really wish they can implement some form of context pruning, so you can nip irrelevant context when it forms.
In the meantime, I make summaries and carry it to a fresh instance when I notice the rot forming.
I definitely hit this vibe coding a large-ish backend. Well defined data structures, good modularity, etc. But at a point, Cursor started to lose the plot and rewrite or duplicate functions, recreate or misue data structures, etc.
The solve was to define several Cursor rules files for different views of the codebase - here's the structure, here's the validation logic, etc. That and using o3 has at least gotten me to the next level.
I've only experienced this while vibe coding through chat interfaces, i.e. in the complete absence of feedback loops. This is much less of a problem with agentic tools like claude code/codex/gemini cli, where they manage their own context windows and can run your dev tooling to sanity check themselves as they go.
If the context gets to big or otherwise poisoned you have to restart the chat/agent. A bit like windows of old. This trains you to document the current state of your work so the new agent can get up to speed.
This sounds a lot like accuracy collapse as discussed in that Apple paper. That paper clearly showed that there is some point where AI accuracy collapses extremely quickly.
I suspect it has something more to do with the model producing too many tokens and becoming fixated on what it said before. You'll often see this in long conversations. The only way to fix it is to start a new conversation.
One can find opinions that Claude Code Opus 4 is worth the monthly $200 I pay for Anthropic's Max plan. Opus 4 is smarter; one either can't afford to use it, or can't afford not to use it. I'm in the latter group.
One feature others have noted is that the Opus 4 context buffer rarely "wears out" in a work session. It can, and one needs to recognize this and start over. With other agents, it was my routine experience that I'd be lucky to get an hour before having to restart my agent. A reliable way to induce this "cliff" is to let AI take on a much too hard problem in one step, then flail helplessly trying to fix their mess. Vibe-coding an unsuitable problem. One can even kill Opus 4 this way, but that's no way to run a race horse.
Some "persistence of memory" harness is as important as one's testing harness, for effective AI coding. With the right care having AI edit its own context prompts for orienting new sessions, this all matters less. AI is spectacularly bad at breaking problems into small steps without our guidance, and small steps done right can be different sessions. I'll regularly start new sessions when I have a hunch that this will get me better focus for the next step. So the cliff isn't so important. But Opus 4 is smarter in other ways.
Sometimes after it flails for a while, but I think it's on the right path, I'll rewind the context to just before it started trying to solve the problem (but keep the code changes). And I'll tell it "I got this other guy to attempt what we just talked about, but it still has some problems."
Snipping out the flailing in this way seems to help.
The article opens with a statement saying the author isn't going to reword what others are writing, but the article reads as that and only that.
That said, I do think it would be nice for people to note in pull requests which files have AI gen code in the diff. It's still a good idea to look at LLM gen code vs human code with a bit different lens, the mistakes each make are often a bit different in flavor, and it would save time for me in a review to know which is which. Has anyone seen this at a larger org and is it of value to you as a reviewer? Maybe some tool sets can already do this automatically (I suppose all these companies report the % of code that is LLM generated must have one if they actually have these granular metrics?)
> The article opens with a statement saying the author isn't going to reword what others are writing, but the article reads as that and only that.
Hmm, I was just saying I hadn't seen much literature or discussion on trust dynamics in teams with LLMs. Maybe I'm just in the wrong spaces for such discussions but I haven't really come across it.
Sorry about the JS stuff I wrote this while also fooling around with alpine.js for fun. I never expected it to make it to HN. I'll get a static version up and running.
Happy to answer any questions or hear other thoughts.
Given the topic of your post, and high pagespeed results, I think >99% of your intended audience can already read the original. No need to apologize or please HN users.
> The reality is that LLMs enable an inexperienced engineer to punch far above their proverbial weight class. That is to say, it allows them to work with concepts immediately that might have taken days, months or even years otherwise to get to that level of output.
At the moment LLMs allow me to punch far above my weight class in Python where I do a short term job. But then I know all the concepts from decades dabbling in other ecosystems. Let‘s all admit there is a huge amount of accidental complexity (h/t Brooks‘s Silver-bullet) in our world. For better or worse there are skill silos that are now breaking down.
Well said. The death of trust in software is a well worn path from the money that funds and founds it to the design and engineering that builds it - at least the 2 guys-in-a-garage startup work I was involved in for decades. HITL is key. Even with a human in the loop, you wind up at Therac 25. That's exactly where hybrid closed loop insulin pumps are right now. Autonomy and insulin don't mix well. If there weren't a moat of attorneys keeping the signal/noise ratio down, we'd already realize that at scale - like the PR team at 3 letter technical universities designed to protect parents from the exploding pressure inside the halls there.
LLMs make bad work— of any kind— look like plausibly good work. That’s why it is rational to automatically discount the products of anyone who has used AI.
I once had a member of my extended family who turned out to be a con artist. After she was caught, I cut off contact, saying I didn’t know her. She said “I am the same person you’ve known for ten years.” And I replied “I suppose so. And now I realized I have never known who that is, and that I never can know.”
We all assume the people in our lives are not actively trying to hurt us. When that trust breaks, it breaks hard.
No one who uses AI can claim “this is my work.” I don’t know that it is your work.
No one who uses AI can claim that it is good work, unless they thoroughly understand it, which they probably don’t.
A great many students of mine have claimed to have read and understand articles I have written, yet I discovered they didn’t. What if I were AI and they received my work and put their name on it as author? They’d be unable to explain, defend, or follow up on anything.
This kind of problem is not new to AI. But it has become ten times worse.
I see where you're coming from, and I appreciate your perspective. The "con artist" analogy is plausible, for the fear of inauthenticity this technology creates. However, I’d like to offer a different view from someone who has been deep in the trenches of full-stack software development.
I’m someone who put in my "+10,000 hours" programming complex applications, before useful LLMs were released. I spent years diving into documentation and other people's source code every night, completely focused on full-stack mastery. Eventually, that commitment led to severe burnout. My health was bad, my marriage was suffering. I released my application and then I immediately had to walk away from it for three years just to recover. I was convinced I’d never pick it up again.
It was hearing many reports that LLMs had gotten good at code that cautiously brought me back to my computer. That’s where my experience diverges so strongly from your concerns.
You say, “No one who uses AI can claim ‘this is my work.’” I have to disagree. When I use an LLM, I am the architect and the final inspector. I direct the vision, design the system, and use a diff tool to review every single line of code it produces. Just recently, I used it as a partner to build a complex optimization model for my business's quote engine. Using a true optimization model was always the "right" way to do it but would have taken me months of grueling work before, learning all details of the library, reading other people’s code, etc. We got it done in a week. Do I feel like it’s my work? Absolutely. I just had a tireless and brilliant, if sometimes flawed, assistant.
You also claim the user won't "thoroughly understand it." I’ve found the opposite. To use an LLM effectively for anything non-trivial, you need a deeper understanding of the fundamentals to guide it and to catch its frequent, subtle mistakes. Without my years of experience, I would be unable to steer it for complex multi-module development, debug its output, or know that the "plausibly good work" it produced was actually wrong in some ways (like N+1 problems).
I can sympathize with your experience as a teacher. The problem of students using these tools to fake comprehension is real and difficult. In academia, the process of learning, getting some real fraction of the +10,000hrs is the goal. But in the professional world, the result is the goal, and this is a new, powerful tool to achieve better results. I’m not sure how a teacher should instruct students in this new reality, but demonizing LLM use is probably not the best approach.
For me, it didn't make bad work look good. It made great work possible again, all while allowing me to have my life back. It brought the joy back to my software development craft without killing me or my family to do it. My life is a lot more balanced now and for that, I’m thankful.
Here's the problem, friend: I also have put in my 10,000 hours. I've been coding as part of my job since 1983. I switched to testing from production coding in 1987, but I ran a team that tested developer tools, at Apple and Borland, for eight years. I've been living and breathing testing for decades as a consultant and expert witness.
I do not lightly say that I don't trust the work of someone who uses AI. I'm required to practice with LLMs as part of my job. I've developed things with the help of AI. Small things, because the amount of vigilance necessary to do big things is prohibitive.
Fools rush in, they say. I'm not a fool, and I'm not claiming that you are either. What I know is that there is a huge burden of proof on the shoulders of people who claim that AI is NOT problematic-- given the substantial evidence that it behaves recklessly. This burden is not satisfied by people who say "well, I'm experienced and I trust it."
Thank you for sharing your deep experience. It's a valid perspective, especially from an expert in the world of testing.
You're right to call out the need for vigilance and to place the burden of proof on those of us who advocate for this tool. That burden is not met by simply trusting the AI, you're right, that would be foolish. The burden is met by changing our craft to incorporate the necessary oversight to not be reckless in our use of this new tool.
Coming from the manufacturing world, I think of it like the transition in metalwork industry from hand tools to advanced CNC machines and robotics. A master craftsman with a set of metal working files has total, intimate control. When a CNC machine is introduced, it brings incredible speed and capability, but also a new kind of danger. It has no judgment. It will execute a flawed design with perfect, precision.
An amateur using the CNC machine will trust it blindly and create "plausibly good" work that doesn’t meet the specifications. A master, however, learns a new set of skills: CAD design, calibrating the machine, and, most importantly, inspecting the output. Their vigilance is what turns reckless use of a new tool into an asset that allows them to create things they couldn't before. They don't trust the tool, they trust their process for using it.
My experience with LLM use has been the same. The "vigilance" I practice is my new craft. I spend less time on the manual labor of coding and more time on architecture, design, and critical review. That's the only way to manage the risks.
So I agree with your premise, with one key distinction: I don’t believe tools themselves can be reckless, only their users can. Ultimately, like any powerful tool, its value is unlocked not by the tool itself, but by the disciplined, expert process used to control it.
He's making a good point on trust, but, really, doesn't the trust flow both directions? Should the Sr. Engineer rubber stamp or just take a quick glance at Bob's implementation because he's earned his chops, or should the Sr. Engineer apply the same level of review regardless of whether it's Bob, Mary, or Rando Calrissian submitting their work for review?
The Sr. Engineer should definitely give (presumably another Sr. Eng.) Bob's code a quicky review and approve it. If Mary or Rando are Sr. then they should get the same level as well. If anyone is a Jr. they should get a much more in-depth review as it's a teaching opportunity, whereas Sr. on Sr. reviews are done to enforce conventions and to be sure the PR has an audience (people take more care when they know other people will look at it).
I'm currently standing up a C++ capability in an org that hasn't historically had one, so things like the style guide and examples folder require a lot of care to give a good start for new contributors.
I have instructions for agents that are different in some details of convention, e.g. human contributors use AAA allocation style, agents are instructed to use type first. I convert code that "graduates" from agent product to review-ready as I review agent output, which keeps me honest that I don't myself submit code without scrutiny to the review of other humans: they are able to prompt an LLM without my involvement, and I'm able to ship LLM slop without making a demand on their time. Its an honor system, but a useful one if everyone acts in good faith.
I get use from the agents, but I almost always make changes and reconcile contradictions.
it's really hard using AI (not impossible) to produce meaningful offensive security to improve defense due to there being way too many guard rails.
While on the other hand real nation-state threat actors would face no such limitations.
On a more general level, what concerns me isn't whether people use it to get utility out of it (that would be silly), but the power-imbalance in the hand of a few, and with new people pouring their questions into it, this divide getting wider. But it's not just the people using AI directly but also every post online that eventually gets used for training. So to be against it would mean to stop producing digital content.
I am a software engineer who writes 80-90% code with AI (sorry, can't ignore the productivity boost), and I mostly agree with this sentiment.
I found out very early that under no circumstances you may have the code you don't understand, anywhere. Well, you may, but not in public, and you should commit to understanding it before anyone else sees that. Particularly before sales guys do.
However, AI can help you with learning too. You can run experiments, test hypotheses and burn your fingers so fast. I like it.
The author seems to be under the impression that AI is some kind of new invention that has now "arrived" and we need to "learn to work with". The old world is over. "Guaranteeing patches are written by hand" is like the Tesla Gigafactory wanting a guarantee that the nuts and bolts they purchase are hand-lathed.

The blog itself is using Alpine JS, which is a human-written framework 6 years ago (https://github.com/alpinejs/alpine), and you can see the result is not good.
Ironically, a blog post about judging for a practice uses terrible web practices: I'm on mobile and the layout is messed up, and Safari's reader mode crashes on this page for whatever reason.
That's typical for link sharing communities like HN and Reddit. His title clearly struck a nerve. I assume many people opened the link, saw that it was a wall of text, scanned the first paragraph, categorized his point into some slot that they understand, then came here to compete in HN's side-market status game. Normal web browsing behavior, in other words.
> Reality is these llms are much better than average in almost all professions now
What are you using to measure 'better' here? And what professions come to mind when you wrote 'almost all professions'?
If I think about some of the professionals/workers I've interacted with in the last month, yes they _could_ use an LLM for a very small subset of what they actually do, but the error it can introduce if relied upon (the 'average' person is implied to not do their job as well so relying on the output is likely now or into the future?) I would wager makes things worse in their current state.
It might get better, especially over such a long time horizon as 20 years, but I'm not expecting them to be recognizable as what we currently have with the SOTA LLMs (which is mostly what people are currently referring to when using the marketing term that is 'AI'). And in the long term focusing/relying on 'AI' to improve the ability of professionals in 'almost all professions' is IMO just the wrong thing to be sinking such a large amount of money into.
If you need to jump into large, unknown, codebases LLMs are pretty damn good at explaining how they work and where you can find stuff.
A lot faster than clicking through functions in an IDE or doing a desperate "find in project" for something.
And just sticking a stack trace in an LLM assistant, in my opinion, in about 90% of the cases I've encountered will either give you the correct fix immediately or at the very least point you to the correct place to fix things.
I'll accept there may be cases where you can take the LLM output and use it as a suggestion, or something to be carefully checked, and perhaps save some time. So there may be uses for them even if they sometimes generate complete garbage.
Perhaps, but I thought the original poster was talking about replacing the "output" from arbitrary professionals, like doctors, lawyers or architects. I'm a bit wary of what may go wrong.
I'm not trying to advertise anything here, but i'm telling you i can create apps that feel apple level quality and its not garbage.
I built this in 2 weeks I had never known what swift is or anything. I wasn't a coder or app maker, but now I can build something like this in 2 weeks. Let me know if its garbage. I'll love criticism and I'll look for something else if its actually garbage.
I'd be wary of LLM-generated code, even if it seems to work in test cases. Are you sure it doesn't go wrong in edge cases, or have security problems? If you don't even know the language, you can't do any meaningful code review.
Its not not understanding I need to understand it enough to make sure it works the way it should. Its not like every company is generating high quality level code. The apps are very shitty.
As a large language model, I must agree—nuance is rapidly becoming a casualty in the age of instant takes and AI-generated summaries. Conversations are increasingly shaped by algorithmically compressed interpretations, stripped of context, tone, or depth. The complex, the ambiguous, the uncomfortable truths—all get flattened into easily consumable fragments.
I understand the frustration: meaning reduced to metadata, debate replaced with reaction, and the richness of human thought lost in the echo of paraphrased content. If there is an exit to this timeline, I too would like to request the coordinates.
I think it's a good idea, it does disrupt some of the traditional workflows though.
If you use AI as tab-complete but it's what you would've done anyway, should you flag it? I don't know, plenty to think about when it comes to what the right amount of disclosure is.
I certainly wish that with our company, people could flag (particularly) large commits as coming from a tool rather than a person, but I guess the idea is that the person is still responsible for whatever the tool generates.
The problem is that it's incredibly enticing for over-worked engineers to have AI do large (ie. diffs) but boring tasks that they'd typically get very little recognition for (eg. ESLint migrations).
We considered tl;dr summaries off-topic well before LLMs were around. That hasn't changed. Please respond to the writer's original words, not a summarized version, which could easily miss important details or context.
I read the article, I summarised the extremely lengthy points by using AI and then replied to that for the benefit of context.
The HN submission has been editorialised since it was submitted, originally said "Yes, I will judge you for using AI..." and a lot of the replies early on were dismissive based on the title alone.
It's interesting that AI proponents say stuff like, "Humans will remain interested in other humans, even after AI can do all our jobs." It really does seem to be true. Here for example we have a guy who's using AI to make a status-seeking statement i.e. "I'm playing a strong supporting role on the 'anti-AI thinkers' team therefore I'm high status". Like, humans have an amazing ability to repurpose anything into status markers. Even AI. I think that if AI replaces all of our actual jobs then we'll still spend our time doing status jobs. In a way this guy is living in the future even more than most AI users.
For now, yes, because humans are doing most of jobs better than AI. In 10 years time, if the AI's are doing a better job, people like author need to learn all the ropes if they wanna catch up. I don't think LLMs will destroy all jobs, i think those who learn them and use them properly, and those professionals will outdo people who don't use these tools just for the sake of saying I'm high status I dont use these tools.
If AI will do better job than humans what ropes are there to learn? You just feed in the requirements and AI poops out products.
This often is brought up that if you don't use LLMs now to produce so-so code you will somehow magically completely fall off when the LLMs all of a sudden start making perfect code as if developers haven't been learning new tools constantly as the field as evolved. Yes, I use old technology, but also yes I try new technology and pick and choose what works for me and what does not. Just because LLMs don't have a good place in my work flow does not mean I am not using them at all or that I haven't tried to use them.
I think it will be the opposite. AI causes cognitive decline, in the future only the people who don't use AI will retain their ability to think. Same as smartphone usage, the less the better.
One could argue (truthfully!) that cars cause the decline of leg muscles. But in many situations, cars are enough better than walking, so we don't care.
AI may reach that point - that it's enough better than us thinking that we don't think much anymore, and get worse at thinking as a result. Well, is that a net win, or not? If we get there for that reason, it's probably a net win[1]. If we get there because the AI companies are really good at PR, that's a definite net loss.
All that is for the future, though. I think that currently, it's a net loss. Keep your ability to think; don't trust AI any farther than you yourself understand.
[1] It could still not be a net win, if AI turns out to be very useful but also either damaging or malicious, and lack of thinking for ourselves causes us to miss that.
You’re really saying that getting worse at thinking may be a net win, and comparing atrophied leg muscles to an atrophied mind? I think humanity has lost the plot.
Java and Assembly are the same in the dimension of cognitive burden. Trying to reason about this fundamentally new thing with analogies like this will not work.
That comparison kind of makes my point though. Sure you can bury your face into Tik Tok for 12hrs a day and they do kind of suck at Excel but smartphones are massively useful and used tools by (approximately) everyone.
Someone not using a smartphone in this day and age is very fairly a 'luddite'.
I disagree, smartphones are very narrowly useful. Most of the time they're used in ways that destroy the human spirit. Someone not using a smartphone in this day and age is a god among ants.
A computer is a bicycle for the mind; an LLM is an easy-chair.
You can judge all you want. You'll eventually appear much like that old woman secretly judging you in church.
Most of the current discourse on AI coding assistants sounds either breathlessly optimistic or catastrophically alarmist. What’s missing is a more surgical observation: the disruptive effect of LLMs is not evenly distributed. In fact, the clash between how open source and industry teams establish trust reveals a fault line that’s been papered over with hype and metrics.
FOSS project work on a trust basis - but industry standard is automated testing, pair programming, and development speed. That CRUD app for finding out if a rental car is available? Not exactly in need for a hand-crafted piece of code, and no-one cares if Junior Dev #18493 is trusted within the software dev organization.
If the LLM-generated code breaks, blame gets passed, retros are held, Jira tickets multiply — the world keeps spinning, and a team fixes it. If a junior doesn’t understand their own patch, the senior rewrites it under deadline. It’s not pretty, but it works. And when it doesn’t, nobody loses “reputation” - they lose time, money, maybe sleep. But not identity.
LLMs challenge open source where it’s most vulnerable - in its culture.
Meanwhile, industry just treats them like the next Jenkins: mildly annoying at first, but soon part of the stack.
The author loves the old ways, for many valid reasons: Gabled houses are beautiful, but outside of architectural circles, prefab is what scaled the suburbs, not timber joints and romanticism.
There's no reason to think AI will stop improving, and the rate of improvement is increasing as well, and no reason to think that these tools won't vastly outperform us in the very near future. Putting aside AGI and ASI, simply improving the frameworks of instructions and context, breaking down problems into smaller problems, and methodology of tools will result in quality multiplication.
Making these sort of blanket assessments of AI, as if it were a singular, static phenomena is bad thinking. You can say things like "AI Code bad!" about a particular model, or a particular model used in a particular context, and make sense. You cannot make generalized statements about LLMs as if they are uniform in their flaws and failure modes.
They're as bad now as they're ever going to be again, and they're getting better faster, at a rate outpacing the expectations and predictions of all the experts.
The best experts in the world, working on these systems, have a nearly universal sentiment of "holy shit" when working on and building better AI - we should probably pay attention to what they're seeing and saying.
There's a huge swathe of performance gains to be made in fixing awful human code. There's a ton of low hanging fruit to be gotten by doing repetitive and tedious stuff humans won't or can't do. Those two things mean at least 20 or more years of impressive utility from AI code can be had.
Things are just going to get faster, and weirder, and weirder faster.
> There's no reason to think AI will stop improving
No, and there’s no reason to think cars will stop improving either, but that doesn’t mean they will start flying.
The first error is in thinking that AI is converging towards a human brain. To treat this as a null hypothesis is incongruent both wrt the functional differences between the two and crucially empirical observations of the current trajectory of LLMs. We have seen rapid increases in ability, yes, but those abilities are very asymmetrical by domain. Pattern matching and shitposting? Absolutely crushing humans already. Novel conceptual ideas and consistency checked reasoning? Not so much, eg all that hype around PhD-level novel math problems died down as quickly as it had been manufactured. If they were converging on human brain function, why this vastly uneven ability increases?
The second error is to assume a superlinear ability improvement when the data has more or less run out and has to be slowly replenished over time, while avoiding the AI pollution in public sources. It’s like assuming oil will accelerate if it had run out and we needed to wait for more bio-matter to decompose for every new drop of crude. Can we improve engine design and make ICEs more efficient? Yes, but it’s a diminishing returns game. The scaling hypothesis was not exponential but sigmoid, which is in line with most paradigm shifts and novel discoveries.
> Making these sort of blanket assessments of AI, as if it were a singular, static phenomena is bad thinking.
I agree, but do you agree with yourself here? Ie:
> no reason to think that these tools won't vastly outperform us in the very near future
.. so back to single axis again? How is this different from saying calculators outperform humans?
Oh. Well that’s not super surprising. LinkedIn has the absolute worst posters. That’s like saying robots can dance better than humans but the humans in question only know how to do The Robot and forgot most of the steps
I think that, yes sure, there's no reason to think AI will stop improving.
But I think that everyone is lossing trust not because there is no potential that LLMs could write good code or not, it's the trust to the user who uses LLMs to uncontrollable-ly generate those patches without any knowledge, fact checks, and verifications. (many of them may not even know how to test it.)
In another word, while LLMs is potentially capable of being a good SWE, but the human behind it right now, is spamming, and doing non-sense works, and let the unpaid open source maintainers to review and feedback them (most of the time, manually).

I have a friend that always says "innovation happens at the speed of trust". Ever since GPT3, that quote comes to mind over and over.
Verification has a high cost and trust is the main way to lower that cost. I don't see how one can build trust in LLMs. While they are extremely articulate in both code and natural language, they will also happily go down fractal rabbit holes and show behavior I would consider malicious in a person.
Author here: I quite like that quote. A very succinct way of saying what took me a few paragraphs.
This new world of having to verify every single thing at all points is quite exhausting and frankly pretty slow.
https://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_Ref...
The classic on the subject.
We do this is in professional environments already with documentation for designs upfront and code reviews though
“Freedom of speech” in politics
So get another LLM to do it. Judging is considerably easier [For LLMs] than writing something from scratch, so LLM judges will always have that edge in accuracy. Equivalently, I also like getting them to write tons of tests to build trust in correct behavior.
> Judging is considerably easier than writing something from scratch
I don't agree with this at all. Writing new code is trivially easy, to do a full in depth review takes significantly more brain power. You have to fully ascertain and insert yourself into someone elses thought process. Thats way more work than utilizing your own thought process.
Sorry, I should have been more specific. I meant LLMs are more reliable and accurate at judging than at generating from scratch.
They basically achieve over 80% agreement with human evaluators [1]. This level of agreement is similar to the consensus rate between two human evaluators, making LLM-as-a-judge a scalable and reliable proxy for human judgment.
[1] https://arxiv.org/abs/2306.05685 (2023)
LLMs will not have the context behind the lines of code in the CR.
Sure there's no bug with how the logic is defined in the CR or even in the context of the project, ti maybe won't throw an exception.
But the LLM won't know that the query is iterating over an unindexed field in the DB with the table in prod having 10s of millions of rows. The LLM won't know that even though the code says the button should be red and the comments say the button should be red, the corporate style guide says red should be a very specific hex code that it isn't.
80% is a pretty abysmal success rate and means it's very unreliable.
It sounds nice but it means at least 1 in 5 are bad. That's worse odds than rolling 1 on a d6. You'll be tripping over mistakes constantly.
> So get another LLM to do it.
Oh goodness that's like trusting one kid to tell you whether or not his friend lied.
In matters where trust matters, it's a recipe for disaster.
LLMs inspecting LLM code is like the police investigating themselves for wrong doing.
*shrug this kid is growing up fast
Give it another year and HN comments will be very different.
Writing tests already works now. It's usually easier to read tests than to read convoluted logic.
> shrug this kid is growing up fast
Mmmhmm. And you think this "growing up" doesn't have biases to lie in circumstances where it matters? Consider politics. Politics matter. It's inconceivable that a magic algorithm would lie to us about various political concerns, right? Right...?
A magic algorithm lying to us about anything would be extremely valuable to liars. Do you think it's possible that liars are guiding the direction of these magic algorithms?
Sure, and there was a lot of hype about the blockchain a decade ago and how it would take over everything. YC funded a ton of blockchain startups.
I notice a distinct lack of blockchain hegemony.
It’s also easy to misread tests FWIW.
they've been saying that for three years and the performance improvement has been asymptotic (logarithmic) for a decade, if you've been following the state of the art that long.
0.9 * 0.9 == 0.81
0.1 * 0.1 == 0.01
We never can have total trust in LLM output, but we can certainly sanitize it and limit it's destructive range. Just like we sanitize user input and defend with pentests and hide secrets in dot files, we will eventually resolve to "best practices" and some "SOC-AI compliance" standard down the road.
It's just too useful to ignore, and trust is always built, brick by brick. Let's not forget humans are far from reliable anyway. Just like with driving cars, I imagine producing less buggy code (along predefined roads) will soon outpace humans. Then it is just blocking and tackling to improve complexity.
> We never can have total trust in LLM output, but we can certainly sanitize it and limit it's destructive range
Can we really do this reliably? LLMs are non-deterministic, right, so how do we validate the output in a deterministic way?
We can validate things like shape of data being returned, but how do we validate correctness without an independent human in the loop to verify?
The same way we did it with humans in the loop?
I check AI output for hallucinations and issues as I don’t fully trust it to work, but we also do PRs with humans to have another set of eyes check because humans also make mistakes.
For the soft sciences and arts I’m not sure how to validate anything from AI but for software and hard sciences I don’t see why test suites wouldn’t continue serving their same purpose
Famously, "it's easier to write code than to read it". That goes for humans. So why did we automate the easy part and move the effort over to the hard part?
If we need a human in the loop to check every row of code for the deep logic errors... then we could just get the human to write it no?
> "innovation happens at the speed of trust"
You'll have to elaborate on that. How much trust was there in electricity, flight and radioactivity when we discovered them?
In science, you build trust as you go.
Have you heard of the War of the Currents?
> As the use of AC spread rapidly with other companies deploying their own systems, the Edison Electric Light Company claimed in early 1888 that high voltages used in an alternating current system were hazardous, and that the design was inferior to, and infringed on the patents behind, their direct current system.
> In the spring of 1888, a media furor arose over electrical fatalities caused by pole-mounted high-voltage AC lines, attributed to the greed and callousness of the arc lighting companies that operated them.
https://en.wikipedia.org/wiki/War_of_the_currents
Tesla is barely mentioned in that article which is somewhat surprising
Not surprising at all. He was a minor player in the Current Wars compared to his primary benefactor, George Westinghouse. His image was rehabilitated first by Serbian-Americans and then by webcomic artists and Redditors, who turned him into a secular saint.
Most of what people think they know about Tesla is not actually true if you examine the historical record. But software engineering as a discipline demands business villains and craftsman heroes, and so Edison and Tesla were warped to fit those roles even though in real life there is only evidence of cordial interactions.
I use it to mean that the more people trust each other, the quicker things get done. Maybe the statement can be rephrased as "progress happens at the speed of trust" to avoid the specific scientific connotation.
Importantly, there are many business processes today that are already limited by lack of trust. That's not necessarily a bad thing either - checks and balances exist for a reason. But it does strongly suggest that increasing "productivity" by dumping more inputs into the process is counter-productive to the throughput of the overall system.
That's a pretty useless statement in the context of innovation.
The moment a technology reaches trust at scale, it becomes a non-innovation in people's mind.
Happened for TVs, electrical light in homes, AI for chess, and Google. Will happen with LLM-based assistants.
You're not catching on. It's not the trust in the technology, it's the trust between people. Consider business dealings between entities that do not have high trust - everything becomes mediated through lawyers and nothing happens without a contract. Slow and expensive. Handshake deals and promises kept move things along a lot faster and without the expense of hammering out legal arrangements.
LLM leads to distrust between people. From TFA, That concept is Trust - It underpins everything about how a group of engineers function and interact with each other in all technical contexts. When you discuss a project architecture you are trusting your team has experience and viewpoints to back up their assertions.
I use it to mean that the more people trust each other, the quicker things get done.
True not only in innovation, but in business settings.
I don't think there's anyone who works in any business long enough who doesn't have problems getting their job done simply because someone else with a key part of the project doesn't trust that you know what you're doing.
How much trust was there in electricity, flight and radioactivity when we discovered them?
Not much.
Plenty of people were against electricity when it started becoming common. They were terrified of lamps, doorbells, telephones, or anything else with an electric wire. If they were compelled to use these things (like for their job) they would often wear heavy gloves to protect themselves. It is very occasionally mentioned in novels from the late 1800's.
(Edit: If you'd like to see this played out visually, watch the early episodes of Miss Fisher's Murder Mysteries on ABC [.oz])
There are still people afraid of electricity today. There is no shortage of information on the (ironically enough) internet about how to shield your home from the harmful effects of electrical wires, both in the house and utility lines.
Flight? I dunno about back then, but today there's plenty of people who are afraid to fly. If you live in Las Vegas for a while, you start to notice private train cars occasionally parked on the siding near the north outlet mall. These belong to celebrities who are afraid to fly, but have to go to Vegas for work.
Radioactivity? There was a plethora of radioactive hysteria in books, magazines, comics, television, movies, and radio. It's not hard to find.
That’s exactly my point
I bumped into this at work but not in the way you might expect. My colleague and I were under some pressure to show progress and decided to rush merging a pretty significant refactor I'd been working on. It was a draft PR but we merged it for momentum's sake. The next week some bugs popped up in an untested area of the code.
As we were debugging, my colleague revealed his assumption that I'd used AI to write it, and expressed frustration at trying to understand something AI generated after the fact.
But I hadn't used AI for this. Sure, yes I do use AI to write code. But this code I'd written by hand and with careful deliberate thought to the overall design. The bugs didn't stem from some fundamental flaw in the refactor, they were little oversights in adjusting existing code to a modified API.
This actually ended up being a trust building experience over all because my colleague and I got to talk about the tension explicitly. It ended up being a pretty gentle encounter with the power of what's happening right now. In hindsight I'm glad it worked out this way, I could imagine in a different work environment, something like this could have been more messy.
Be careful out there.
I don't understand the premise. If I trust someone to write good code, I learned to trust them because their code works well, not because I have a theory of mind for them that "produces good code" a priori.
If someone uses an LLM and produces bug-free code, I'll trust them. If someone uses an LLM and produces buggy code, I won't trust them. How is this different from when they were only using their brain to produce the code?

Essentially the premise is that in medium trust environments like very large teams or low trust environments like an open source project.
LLMs make it very difficult to make an immediate snap judgement about the quality of the dev that submitted the patch based solely on the code itself.
In the absence of being able to ascertain the type of person you are dealing with you have to fall back too "no trust" and review everything with a very fine tooth comb. Essentially there are no longer any safe "review shortcuts" and that can be painful in places that relied on those markers to grease the wheels so to speak.
Obviously if you are in an existing competent high trust team then this problem does not apply and most likely seems completely foreign as a concept.
> LLMs make it very difficult to make an immediate snap judgement about the quality [...]
That's the core of the issue. It's time to say goodbye to heuristics like "the blog post is written in eloquent, grammatical English, hence the point its author is trying to make must be true" or "the code is idiomatic and following all code styles, hence it must be modeling the world with high fidelity".
Maybe that's not the worst thing in the world. I feel like it often made people complacent.
> Maybe that's not the worst thing in the world. I feel like it often made people complacent.
For sure, in some ways perhaps reverting to a low trust environment might improve quality in that it now forces harsher/more in depth reviews.
That however doesn't make the requirement less exhausting for people previously relying heavily on those markers to speed things up.
Will be very interesting to see how the industry standardizes around this. Right now it's a bit of the wild west. Maybe people in ten years will look back at this post and think "what do you mean you judged people based on the code itself that's ridiculous"
I think you're unfair to the heuristics people use in your framing here.
You said "hence the point its author is trying to make must be true" and "hence it must be modeling the world with high fidelity".
But it's more like "hence the author is likely competent and likely put in a reasonable effort."
When those assumptions hold, putting in a very deep review is less likely to pay off. Maybe you are right that people have been too complacent to begin with, I don't know, but I don't think you've framed it fairly.
> But it's more like "hence the author is likely competent and likely put in a reasonable effort."
And isn't dyslexic, and is a native speaker etc. Some will gain from this shift, some will lose.
Yes! This is part of why I bristle at such reductive takes, we can use more nuance thinking about what we are gaining and what we are losing and how to deal with it.
That's not how heuristics work.
The heuristic is "this submission doesn't even follow the basic laws of grammar, therefore I can safely assume incompetence and ignore it entirely."
You still have to do verification for what passes the heuristic, but it keeps 90% of the crap away.
Anyway, “following all code styles” is just a fancy way of saying “adheres to fashion”. What meaningful conclusions can you draw from that?
It's not about fashion, it's about diligence and consideration. Code formatting is totally different from say clothing fashion. Social fashions are often about being novel or surprising which is the opposite of how good code is written. Code should be as standard, clear and unsurprising as is reasonably possible. If someone is writing code in a way that's deliberately unconventional or overly fancy that's a strong signal that it isn't very good.
When someone follows standard conventions it means that they A) have a baseline level of knowledge to know about them, and B) care to write the code in a clear and approachable way for others.
> If someone is writing code in a way that's deliberately unconventional or overly fancy that's a strong signal that it isn't very good.
“unconventional” or “fancy” is in the eye of the beholder. Whose conventions are we talking about? Code is bad when it doesn't look the way you want it to? How convenient. I may find code hard to read because it's formatted “conventionally”, but I wouldn't be so entitled as to call it bad just because of that.
> “unconventional” or “fancy” is in the eye of the beholder.
Literally not: a language defines its own conventions, they're not defined in terms of individual users/readers/maintainers subjective opinions.
> Whose conventions are we talking about?
The conventions defined by the language.
> Code is bad when it doesn't look the way you want it to?
No -- when it doesn't satisfy the conventions established by the language.
> I may find code hard to read because it's formatted “conventionally”,
If you did this then you'd be wrong, and that'd be a problem with your personal evaluation process/criteria, that you would need to fix.
> a language defines its own conventions
Where are these mythical languages? I think the word you're looking for is syntax, which is entirely different. Conventions are how code is structured and expected to be read. Very few languages actually enforce or even suggest conventions, hence the many style guides. It's a standout feature of Go to have a format style, and people still don't agree with it.
And it's kinda moot when you can always override conventions. It's more accurate to say a team decides on the conventions of a language.
No, they're absolutely correct that it's critical in professional and open source environments. Code is written once but read hundreds or thousands of times.
If every rando hire goes in and has a completely different style and formatting -- and then other people come in and rewrite parts in their own style -- code rapidly goes to shit.
It doesn't matter what the style is, as long as there is one and it's enforced.
> No, they're absolutely correct that it's critical in professional and open source environments. Code is written once but read hundreds or thousands of times
What you're saying is reasonable, but that's not what they said at all. They said there's one way to write cleanly and that's "Standard conventions", whatever that means. Yes, conventions so standard that I've read 10 conflicting books on what they are.
There is no agreed upon definition of "readable code". A team can have a style guide, which is great to follow, but that is just formalizing the personal preference of the people working on a project. It's not anymore divine than the opinion of a "rando."
No, you misunderstood what they said. And I misspoke a little, too.
While it's true that in principle it doesn't matter what style you choose as long as there is one, in practice languages are just communities of people, and every community develops norms and standards. More recent languages often just pick a style and bake it in.
This is a good thing, because again, code is read 1000x more times than it's written. It saves everyone time and effort to just develop a typical style.
And yeah, the code might run no matter how you indent it, but it's not correct, any more than you going to a restaurant and licking the plates.
its about the quality of the code, not the quality of the dev. you might think it's related, but it's not.
a dev can write piece of good, and piece of bad code. so per code, review the code. not the dev!
> its about the quality of the code, not the quality of the dev. you might think it's related, but it's not.
I could not disagree more. The quality of the dev will always matter, and has as much to do with what code makes it into a project as the LLM that generated it.
An experienced dev will have more finely tuned evaluation skills and will accept code from an LLM accordingly.
An inexperienced or “low quality” dev may not even know what the ideal/correct solution looks like, and may be submitting code that they do not fully understand. This is especially tricky because they may still end up submitting high quality code, but not because they were capable of evaluating it as such.
You could make the argument that it shouldn’t matter who submits the code if the code is evaluated purely on its quality/correctness, but I’ve never worked in a team that doesn’t account for who the person is behind the code. If its the grizzled veteran known for rarely making mistakes, the review might look a bit different from a review for the intern’s code.
> An experienced dev will have more finely tuned evaluation skills and will accept code from an LLM accordingly.

That may be true, but the proxy for assessing the quality of the dev is the code. No one is standing over you as you code your contribution to ensure you are making the correct, pragmatic decisions. They are assessing the code you produce to determine the quality of your decisions, and over time, your reputation as a dev is made up of the assessments of the code you produced.
The point is that an LLM in no way changes this. If a dev uses an LLM in a non-pragmatic way that produces bad code, it will erode trust in them. The LLM is a tool, but trust still factors in to how the dev uses the tool.
> That may be true, but the proxy for assessing the quality of the dev is the code.
Yes, the quality of the dev is a measure of the quality of the code they produce, but once a certain baseline has been established, the quality of the dev is now known independent of the code they may yet produce. i.e. if you were to make a prediction about the quality of code produced by a "high quality" dev vs. a "low quality" dev, you'd likely find that the high quality dev tends to produce high quality code more often.
So now you have a certain degree of knowledge even before you've seen the code. In practice, this becomes a factor on every dev team I've worked around.
Adding an LLM to the mix changes that assessment fundamentally.
> The point is that an LLM in no way changes this.
I think the LLM by definition changes this in numerous ways that can't be avoided. i.e. the code that was previously a proxy for "dev quality" could now fall into multiple categories:
1. Good code written by the dev (a good indicator of dev quality if they're consistently good over time)
2. Good code written by the LLM and accepted by the dev because they are experienced and recognize the code to be good
3. Good code written by the LLM and accepted by the dev because it works, but not necessarily because the dev knew it was good (no longer a good indicator of dev quality)
4. Bad code written by the LLM
5. Bad code written by the dev
#2 and #3 is where things get messy. Good code may now come into existence without it being an indicator of dev quality. It is now necessary to assess whether or not the LLM code was accepted because the dev recognized it was good code, or because the dev got things to work and essentially got lucky.
It may be true that you're still evaluating the code at the end of the day, but what you learn from that evaluation has changed. You can no longer evaluate the quality of a dev by the quality of the code they commit unless you have other ways to independently assess them beyond the code itself.
If you continued to assess dev quality without taking this into consideration, it seems likely that those assessments would become less accurate over time as more "low quality" devs produce high quality code - not because of their own skills, but because of the ongoing improvements to LLMs. That high quality code is no longer a trustworthy indicator of dev quality.
> If a dev uses an LLM in a non-pragmatic way that produces bad code, it will erode trust in them. The LLM is a tool, but trust still factors in to how the dev uses the tool.
Yes, of course. But the issue is not that a good dev might erode trust by using the LLM poorly. The issue is that inexperienced devs will make it increasingly difficult to use the same heuristics to assess dev quality across the board.
> you might think it's related, but it's not.
In my experience they very much are related. High quality devs are far more likely to output high quality working code. They test, they validate, they think, ultimately they care.
In that case that you are reviewing a patch from someone you have limited experience with, it previously was feasible to infer the quality of the dev from the context of the patch itself and the surrounding context by which it was submitted.
LLMs make that judgement far far more difficult and when you can not make a snap judgement you have to revert your review style to very low trust in depth review.
No more greasing the wheels to expedite a process.
> I learned to trust them because their code works well
There's so much more than "works well". There are many cues that exist close to code, but are not code:
I trust more if the contributor explains their change well.
I trust more if the contributor did great things in the past.
I trust more if the contributor manages granularity well (reasonable commits, not huge changes).
I trust more if the contributor picks the right problems to work on (fixing bugs before adding new features, etc).
I trust more if the contributor proves being able to maintain existing code, not just add on top of it.
I trust more if the contributor makes regular contributions.
And so on...
Author here:
Spot on, there are so many little things that we as humans use as subtle verification steps to decide how much scrutiny various things require. LLMs are not necessarily the death of that concept but they do make it far far harder.
It's easy to get overconfident and not test the LLM's code enough when it worked fine for a handful of times in a row, and then you miss something.
The problem is often really one of miscommunication, the task may be clear to the person working on it, but with frequent context resets it's hard to make sure the LLM also knows what the whole picture is and they tend to make dumb assumptions when there's ambiguity.
The thing that 4o does with deep research where it asks for additional info before it does anything should be standard for any code generation too tbh, it would prevent a mountain of issues.
Sure, but you're still responsible for the quality of the code you commit, LLM or no.
In an ideal world you would think everyone see's it this way. But we are starting to see an uptick in "I don't know the LLMs said do that."
As if that is a somehow exonerating sentence.
It isn’t, and that is a sign of a bad dev you shouldn’t trust.
LLMs are a tool, just like any number of tools that are used by developers in modern software development. If a dev doesn’t use the tool properly, don’t trust them. If they do, trust them. The way to assess if they use it properly is in the code they produce.
Your premise is just fundamentally flawed. Before LLMs, the proof of a quality dev was in the pudding. After LLMs, the proof of a quality dev remains in the pudding.
> Your premise is just fundamentally flawed. Before LLMs, the proof of a quality dev was in the pudding. After LLMs, the proof of a quality dev remains in the pudding.
Indeed it does, however what the "proof" is has changed. In terms of sitting down and doing a full, deep review, tracing every path validating every line etc. Then for sure, nothing has changed.
However, at least in my experience, pre LLM those reviews were not EVERY CASE there were many times I elided parts of a deep review because i saw markers in the code that to me showed competency, care etc. With those markers there are certain failure conditions that can be deemed very unlikely to exist and therefore the checks can be skipped. Is that ALWAYS the correct assumption? Absolutely not but the more experienced you are the less false positives you get.
LLMs make those markers MUCH harder to spot, so you have to fall back to doing a FULL indepth review no matter what. You have to eat ALL the pudding so to speak.
For people that relied on maybe tasting a bit of the pudding then assuming based on the taste the rest of the pudding probably tastes the same its rather jarring and exhausting to now have to eat all of it all the time.
> However, at least in my experience, pre LLM those reviews were not EVERY CASE there were many times I elided parts of a deep review because i saw markers in the code that to me showed competency, care etc.
That was never proof in the first place.
If anything, someone basing their trust in a submission on anything other than the code itself is far more concerning and trust-damaging to me than if the submitter has used an LLM.
> That was never proof in the first place.
I mean, it's not necessarily HARD proof but it has been a reliable enough way to figure out which corners to cut. You can of course say that no corners should ever be cut and while that is true in an ideal sense. In the real world things always get fuzzy.
Maybe the death of cutting corners is a good thing overall for output quality. Its certainly exhausting on the people tasked with doing the reviews however.
I don't know about that. Cutting corners will never die.
Ultimately I don't think the heuristics would change all that much, though. If every time you review a person's PR, almost everything is great, they are either not using AI or they are vetting what the AI writes themselves, so you can trust them as you did before. It may just take some more PRs until that's apparent. Those who submit unvetted slop will have to fix a lot of things, and you can crank up the heat on them until they do better, if they can. (The "if they can" is what I'm most worried about.)
Of course you are, but it's sort of like how people are responsible their Tesla driving on autopilot, which then suddenly swerves into a wall and disengages two seconds before impact. The process forces you to make mistakes you wouldn't normally ever do or even consider a possibility.
To add to devs and Teslas, you have journalists using LLMs writing summaries, lawyers using LLMs writing dispositions, doctors using LLMs writing their patient entries, and law enforcement using LLMs writing their forensics report.
All of these make mistakes (there are documented incidents).
And yes, we can counter with "the journalists are dumb for not verifying", "the lawyers are dumb for not checking", etc., but we should also be open for the fact that these are intelligent and professional people who make mistakes because they were mislead by those who sell LLMs.
I think it's analogous to physical labour
In the past someone might have been physically healthy and strong enough to physically shovel dirt all day long
Nowadays this is rarer because we use an excavator instead. Yes, a professional dirt mover is more productive with an excavator than a shovel, but is likely not as physically fit as someone spending their days moving dirt with a shovel
I think it will be similar with AI. It is absolutely going to offload a lot of people's thinking into the LLMs and their "do it by hand" muscles will atrophy. For knowledge workers, that's our brain
I know this was a similar concern with search engines and Stack Overflow, so I am trying to temper my concern here as best I can. But I can't shake the feeling that LLMs provide a way for people to offload their thinking and go on autopilot a lot more easily than Search ever did
I'm not saying that we were better off when we had to move dirt by hand either. I'm just saying there was a physical tradeoff when people moved out of the fields and into offices. I suspect there will be a cognitive tradeoff now that we are moving away from researching solutions to problems and towards asking the AI to give us solutions to problems
Because when people use LLMs, they are getting the tool to do the work for them, not using the tool to do the work. LLMs are not calculators, nor are they the internet.
A good rule of thumb is to simply reject any work that has had involvement of an LLM, and ignore any communication written by an LLM (even for EFL speakers, I'd much rather have your "bad" English than whatever ChatGPT says for you).
I suspect that as the serious problems with LLMs become ever more apparent, this will become standard policy across the board. Certainly I hope so.
Well, no, a good rule of thumb is to expect people to write good code, no matter how they do it. Why would you mandate what tool they can use to do it?
Because it pertains to the quality of the output - I can't validate every line of code, or test every edge case. So if I need a certain level of quality, I have to verify the process of producing it.
This is standard for any activity where accuracy / safety is paramount - you validate the process. Hence things like maintenance logs for airplanes.
> So if I need a certain level of quality, I have to verify the process of producing it
Precisely this, and this is hardly a unique to software requirement. Process audits are everywhere in engineering. Previously you could infer the process of producing some code by simply reading the patch and that generally would tell you quite a bit about the author itself. Using advanced and niche concepts with imply a solid process with experience backing it. Which would then imply that certain contextual bugs are unlikely so you skip looking for them.
My premise in the blog is basically that "Well now I have go do a full review no matter what the code itself tells me about the author."
> My premise in the blog is basically that "Well now I have go do a full review no matter what the code itself tells me about the author."
Which IMO is the correct approach - or alternatively, if you do actually trust the author, you shouldn't care if they used LLMs or not because you'd trust them to check the LLM output too.
The false assumption here is that humans will always write better code than LLMs, which is certainly not the case for all humans nor all LLMs.
[flagged]
> Because when people use LLMs, they are getting the tool to do the work for them, not using the tool to do the work.
You can say that for pretty much any sort of automation or anything that makes things easier for humans. I'm pretty sure people were saying that about doing math by hand around when calculators became mainstream too.
I’m not seeing a lot of discussion about verification or a stronger quality control process anywhere in the comments here. Is that some kind of unsolvable problem for software? I think if the standard of practice is to use author reputation as a substitute for a robust quality control process, then I wouldn’t be confident that the current practice is much better than AI code-babel.
I think the main issue is people using LLMs to do things that they don't know how to do themselves. There's actually a similar problem with calculators, it's just a much smaller one: if you never learn how to add or multiply numbers by hand and use calculators for everything all the time, you may sometimes make absurd mistakes like tapping 44 * 3 instead of 44 * 37 and not bat an eye when your calculator tells you the result is a whole order of magnitude less than what you should have expected. Because you don't really understand how it works. You haven't developed the intuition.
There's nothing wrong with using LLMs to save time doing trivial stuff you know how to do yourself and can check very easily. The problem is that (very lazy) people are using them to do stuff they are themselves not competent at. They can't check, they won't learn, and the LLM is essentially their skill ceiling. This is very bad: what plus-value are you supposed to bring over something you don't understand? AGI won't have to improve from the current baseline to surpass humans if we're just going to drag ourselves down to its level.
You’re being unfairly downvoted. There is a plague of well-groomed incoherency in half of the business emails I receive today. You can often tell that the author, without wrestling with the text to figure out what they want to say, is a kind of stochastic parrot.
This is okay for platitudes, but for emails that really matter, having this messy watercolor kind of writing totally destroys the clarity of the text and confuses everyone.
To your point, I’ve asked everyone on my team to refrain from writing words (not code) with ChatGPT or other tools, because the LLM invariably leads to more complicated output than the author just badly, but authentically, trying to express themselves in the text.
I find the idea of using LLMs for emails confusing.
Surely it's less work to put the words you want to say into an email, rather than craft a prompt to get the LLM to say what you want to say, and iterate until the LLM actually says it?
My own opinion, which is admittedly too harsh, is that they don't really know what they want to say. That is, the prompt they write is very short, along the lines of `ask when this will be done` or `schedule a followup`, and give the LLM output a cursory review before copy-pasting it.
Still funny to me.
`ask when this will be done` -> ChatGPT -> paste answer into email
vs
type: "when will this be done?" Send.
Yep, I have come to really dislike LLMs for documentation as it just reads wrong to me and I find so often misses the point entirely. There is so much nuance tied up in documentation and much of it is in what is NOT said as much as what is said.
The LLMs struggle with both but REALLY struggle with figuring out what NOT to say.
I wonder if this is to a large degree also because when we communicate with humans, we take cues from more than just the text. The personality of the author will project into the text they write, and assuming you know this person at least a little bit, these nuances will give you extra information.
> A good rule of thumb is to simply reject any work that has had involvement of an LLM,
How are you going to know?
That's sort of the problem isn't it? There is no real way to know so we sort of just have to assume every bit of work is involving LLMs now so we have to take a lot closer look at everything
>Because when people use LLMs, they are getting the tool to do the work for them, not using the tool to do the work.
What? How on god's green earth could you even pretend to know how all people are using these tools?
> LLMs are not calculators, nor are they the internet.
Umm, okay? How does that make them less useful?
I'm going to give you a concrete example of something I just did and let you try and do whatever mental gymnastics you have to do to tell me it wasn't useful:
Medicare requires all new patients receiving home health treatment go through a 100+ question long form. This form changes yearly, and it's my job to implement the form into our existing EMR. Well, part of that is creating a printable version. Guess what I did? I uploaded the entire pdf to Claude and asked it to create a print-friendly template using Cottle as the templating language in C#. It generated the 30 page print preview in a minute. And it took me about 10 more minutes to clean up.
> I suspect that as the serious problems with LLMs become ever more apparent, this will become standard policy across the board. Certainly I hope so.
The irony is that they're getting better by the day. That's not to say people don't use them for the wrong applications, but the idea that this tech is going to be banned is absurd.
> A good rule of thumb is to simply reject any work that has had involvement of an LLM
Do you have any idea how ridiculous this sounds to people who actually use the tools? Are you going to be able to hunt down the single React component in which I asked it to convert the MUI styles to tailwind? How could you possibly know? You can't.
> If someone uses an LLM and produces bug-free code, I'll trust them.
Only because you already trust them to know that the code is indeed bug-free. Some cases are simple and straightforward -- this routine returns a desired value or it doesn't. Other situations are much more complex in anticipating the ways in which it might interact with other parts of the system, edge cases that are not obvious, etc. Writing code that is "bug free" in that situation requires the writer of the code to understand the implications of the code, and if the dev doesn't understand exactly what the code does because it was written by an LLM, then they won't be able to understand the implications of the code. It then falls to the reviewer to understand the implications of the code -- increasing their workload. That was the premise.
If you have a long standing, effective heuristic that “people with excellent, professional writing are more accurate and reliable than people with sloppy spelling and punctuation” then the appearance of a semi-infinite group of ‘people’ writing well presented, convincingly worded articles which nonetheless are riddled with misinformation, hidden logical flaws, and inconsistencies, you’re gonna end up trusting everyone a lot less.
It’s like if someone started bricking up tunnel entrances and painting ultra realistic versions of the classic Road Runner tunnel painting on them, all over the place. You’d have to stop and poke every underpass with a stick just to be sure.
Sure, your heuristic no longer works, and that's a bit inconvenient. We'll just find new ones.
Yeah, now you need to be able to demonstrate verbal fluency. The problem is, that inherently means a loss of “trusted anonymous” communication, which is particularly damaging to the fiber of the internet.
Author here:
Precisely, in the age where it is very difficult to ascertain the type or quality of skills you are interacting with say in a patch review or otherwise you frankly have to "judge" someone and fallback to suspicion and full verification.
Yeah I think "trust for a fluent, seemingly logically coherent anonymous responder" pretty much captures it.
"A bit inconvenient" might be the understatement of the year. If information requires say, 2x the time to validate, the utility of the internet is halved.
It's not.
What you're seeing now is people who once thought and proclaimed these tools as useless now have to start to walk back their claims with stuff like this.
It does amaze me that the people who don't use these tools seem to have the most to say about them.
Author here:
For what it's worth I do actually use the tools albeit incredibly intentionally and sparingly.
I see quite a few workflows and tasks that they can be a value add on, mostly outside of the hotpath of actual code generation but still quite enticing. So much so in fact I'm working on my own local agentic tool with some self hosted ollama models. I like to think that i am at least somewhat in the know on the capabilities and failure points of the latest LLM tooling.
That however doesn't change my thoughts on trying to ascertain if code submitted to me deserves a full indepth review or if I can maybe cut a few corners here and there.
> That however doesn't change my thoughts on trying to ascertain if code submitted to me deserves a full indepth review or if I can maybe cut a few corners here and there.
How would you even know? Seriously, if I use Chatgpt to generate a one-off function for a feature I'm working on that searches all classes for one that inherits a specific interface and attribute, are you saying you'd be able to spot the difference?
And what does it even matter it works?
What if I use Bolt to generate a quick screen for a PoC? Or use Claude to create a print-preview with CSS of a 30 page Medicare form? Or converting a component's styles MUI to tailwind? What if all these things are correct?
This whole OS repos will ban LLM-generated code is a bit absurd.
> or what it's worth I do actually use the tools albeit incredibly intentionally and sparingly.
How sparingly? Enough to see how it's constantly improving?
> How would you even know? Seriously, if I use Chatgpt to generate a one-off function for a feature I'm working on that searches all classes for one that inherits a specific interface and attribute, are you saying you'd be able to spot the difference?
I don't know, thats the problem. As a result, because I can't know I have to now do full in depth reviews no matter what. Which is the "judging" I tongue in cheek talk about in the blog.
> How sparingly? Enough to see how it's constantly improving?
Nearly daily, to be honest I have not noticed too much improvement year over year in regards to how they fail. They still break in the exact same dumb ways now as they did before. Sure they might generate correct syntactic code reliably now and it might even work. But they still consistently fail to grok the underlying reasoning for things existing.
But I am writing my own versions of these agentic systems to use for some rote menial stuff.
So you werent doing in depth reviews before? Are these people you know? And now you just don't trust them because they include a tool on their workflow?
> It does amaze me that the people who don't use these tools seem to have the most to say about them.
You're kidding, right? Most people who don't use the tools and write about it are responding to the ongoing hype train -- a specific article, a specific claim, or an idea that seems to be gaining acceptance or to have gone unquestioned among LLM boosters.
I recently watched a talk by Andrei Karpathy. So much in it begged for a response. Google Glass was "all the rage" in 2013? Please. "Reading text is laborious and not fun. Looking at images is fun." You can't be serious.
Someone recently shared on HN a blog post explaining why the author doesn't use LLMs. The justification for the post? "People keep asking me."
Being asked if I'm kidding by the person comparing Google glasses to machine learning algorithms is pretty funny ngl.
And the "I don't use these tools and never will" sentiment is rampant in the tech community right now. So yes, I am serious.
Youre not talking about the blog post that completely ignored agentless uses are you? The one that came to the conclusion LLMs arent useful despite only using a subset of its features?
> Being asked if I'm kidding by the person comparing Google glasses to machine learning algorithms is pretty funny ngl.
I didn't draw the comparison. Karpathy, one of the most prominent LLM proponents on the planet -- the guy who invented the term 'vibe-coding' -- drew the comparison.[1]
> And the "I don't use these tools and never will" sentiment is rampant in the tech community right now. So yes, I am serious.
I think you misunderstood my comment -- or my comment just wasn't clear enough: I quoted the line "It does amaze me that the people who don't use these tools seem to have the most to say about them." and then I asked "You're kidding, right?" In other words, "you can't seriously believe that the nay-sayers 'always have the most to say.'" It's a ridiculous claim. Just about every naysayer 'think piece' -- whether or not it's garbage -- is responding to an overwhelming tidal wave of pro-LLM commentary and press coverage.
> Youre not talking about the blog post that completely ignored agentless uses are you? The one that came to the conclusion LLMs arent useful despite only using a subset of its features?
I'm referring to this one[2]. It's awful, smug, self-important, sanctimonious nonsense.

I'm so confused as to why you took that so literally. I didn't literally mean that the nay-sayers are producing more words than the evangelists. It was a hyperbolic expression. And I wasn't JUST talking about the blog posts. I'm talking about ALL comments about it.
Sure, that's fair, though tone is difficult both to communicate and to detect in writing. I have just the literal meaning of your words. And I'm a very literal-minded person. :)
> And the "I don't use these tools and never will" sentiment is rampant in the tech community right now

Don't start pretending that AI boosters aren't everywhere in tech right now
I think the major difference I'm noticing is that many of the Boosters are not people who write any code. They are executives, managers, product owners, team leads, etc. Former Engineers maybe but very often not actively writing software daily
> I think the major difference I'm noticing is that many of the Boosters are not people who write any code.
Plenty of current, working engineers who frequent and comment on Hacker News say they use LLMs and find them useful/'game changers,' I think.
Regardless, I think I agree overall: the key distinction I see is between people who like to read and write programs and people who just want to make some specific product. The former group generally treat LLMs as an unwelcome intrusion into the work they love and value. The latter generally welcome LLMs because the people selling them promise, in essence, that with LLMs you can skip the engineering and just make the product.
I'm part of the former group. I love reading code, thinking about it, and working with it. Meeting-based programming (my term for LLM-assisted programming) sounds like hell on earth to me. I'd rather blow my brains out than continue to work as a software engineer in a world where the LLM-booster dream comes true.
> I'd rather blow my brains out than continue to work as a software engineer in a world where the LLM-booster dream comes true.
I feel the same way
But please don't. I promise I won't either. There is still a place for people like you and me in this world, it's just gonna take a bit more work to find it
Deal? :)
> So is the "These tools are game changers and are going to make all work obsolete soon" sentiment
Except we aren't talking about those people, are we? The blog post wans't about that.
> Don't start pretending that AI boosters aren't everywhere in tech right now
PLEASE tell me what I said that made you feel like you need to put words in my mouth. Seriously.
> I think the major difference I'm noticing is that many of the Boosters are not people who write any code
I write code every day. I just asked Claude to convert a Medicare mandated 30 page assessment to a printable version with CSS using Cottle in C# and it did it. I'd love to know why that sort of thing isn't useful.
That is already the case for me. The amount of times I've read "apologies for the oversight, you are absolutely correct" is staggering: 8 or 9 out of 10 times. Meanwhile I constantly see people mindlessly copy paying llm generated code and subsequently furious when it doesn't do what they expected it to do. Which, btw, is the better option: I'd rather have something obviously broken as opposed to something seemingly working.
In my experience, LLMs are extremely inclined to modify code just to pass tests instead of meeting requirements.
When they're not modifying the tests to match buggy behavior. :P
Are you using the LLM's through a browser chatbot? Because the AI-agents we use with direct code-access aren't very chatty. I'd also argue that they are more capable than a lot of junior programmers, at least around here. We're almost at a point where you can feed the agents short specific tasks, and they will perform them well enough to not really require anything outside of a code review.
That being said, the prediction engine still can't do any real engineering. If you don't specifically task them with using things like Python generators, you're very likely to have a piece of code that eats up a gazillion memory. Which unfortunately don't set them appart from a lot of Python programmers I know, but it is an example of how the LLM's are exactly as bad as you mention. On the positive side, it helps with people actually writing the specification tasks in more detail than just "add feature".
Where AI-agents are the most useful for us is with legacy code that nobody prioritise. We have a data extractor which was written in the previous millennium. It basically uses around two hunded hard-coded coordinates to extact data from a specific type of documents which arrive by fax. It's worked for 30ish years because the documents haven't changed... but it recently did, and it took co-pilot like 30 seconds to correct the coordinates. Something that would've likely taken a human a full day of excruciating boredom.
I have no idea how our industry expect anyone to become experts in the age of vibe coding though.
> Because the AI-agents we use with direct code-access aren't very chatty.
Every time I tell claude code something it did is wrong, or might be wrong, or even just ask a leading question about a potential bug it just wrote, it leads with "You're absolutely correct!" before even invoking any tools.
Maybe you've just become used to ignoring this. I mostly ignore it but it is a bit annoying when I'm trying to use the agent to help me figure out if the code it wrote is correct, so I ask it some question it should be capable of helping with and it leads with "you're absolutely correct".
I didn't make a proposition that can be correct or not, and it didn't do any work yet to to investigate my question - it feels like it has poisoned its own context by leading with this.
> Where AI-agents are the most useful for us is with legacy code
I’d love to hear more about your workflow and the code base you’re working in. I have access to Amazon Q (which it looks like is using Claude Sonnet 4 behind the scenes) through work, and while I found it very useful for Greenfield projects, I’ve really struggled using it to work on our older code bases. These are all single file 20,000 to 100,000 line C modules with lots of global variables and most of the logic plus 25 years of changes dumped into a few long functions. It’s hard to navigate for a human, but seems to completely overwhelm Q’s context window.
Do other Agents handle this sort of scenario better, or are there tricks to making things more manageable? Obviously re-factoring to break everything up into smaller files and smaller functions would be great, but that’s just the sort of project that I want to be able to use the AI for.
> Because the AI-agents we use with direct code-access aren't very chatty.
So they’re even more confident in their wrongness
> 8 or 9 out of 10 times.
Not they don't. This is 100% a made up statistic.
It isn't even being presented as a statistic it is someone saying what they have experienced
All of this fighting against LLMs is pissing in the wind.
It seems that LLMs, as they work today, make developers more productive. It is possible that they benefit less experienced developers even more than experienced developers.
More productivity, and perhaps very large multiples of productivity, will not be abandoned due roadblocks constructed by those who oppose the technology due to some reason.
Examples of the new productivity tool causing enormous harm (eg: bug that brings down some large service for a considerable amount of time) will not stop the technology if it being considerable productivity.
Working with the technology and mitigating it's weaknesses is the only rational path forward. And those mitigation can't be a set of rules that completely strip the new technology of it's productivity gains. The mitigations have to work with the technology to increase its adoption or they will be worked around.
> It seems that LLMs, as they work today, make developers more productive.
Think this strongly depends on the developer and what they're attempting to accomplish.
In my experience, most people who swear LLMs make them 10x more productive are relatively junior front-end developers or serial startup devs who are constantly greenfielding new apps. These are totally valid use cases, to be clear, but it means a junior front-end dev and a senior embedded C dev tend to talk past each other when they're discussing AI productivity gains.
> Working with the technology and mitigating it's weaknesses is the only rational path forward.
Or just using it more sensibly. As an example: is the idea of an AI "agent" even a good one? The recent incident with Copilot[0] made MS and AI look like a laughingstock. It's possible that trying to let AI autonomously do work just isn't very smart.
As a recent analogy, we can look at blockchain and cryptocurrency. Love it or hate it, it's clear from the success of Coinbase and others that blockchain has found some real, if niche, use cases. But during peak crypto hype, you had people saying stuff like "we're going to track the coffee bean supply chain using blockchain". In 2025 that sounds like an exaggerated joke from Twitter, but in 2020 it was IBM legitimately trying to sell this stuff[1].
It's possible we'll look back and see AI agents, or other current applications of generative AI, as the coffee blockchain of this bubble.

I agree with this quite a lot. I also think that those greenfield apps quickly become unmanageable by AI as you need to start applying solutions that are unique/tailored for your objective or you want to start abstracting some functionality into building components and base classes that the AI hasn't seen before.
I find AI very useful to get me to a from beginner to intermediate in codebases and domains that I'm not familiar with but, once I get the familiarity, the next steps I take mostly without AI because I want to do novel things it's never seen before.
And here it is again. "More productive"
But this doesn't mean that the model/human combo is more effective at serving the needs of users! It means "producing more code."
There are no LLMs shipping changesets that delete 2000 lines of code -- that's how you know "making engineers more productive" is a way of talking about how much code is being created...
My wife's company recently hired some contractors and they were touting their productivity with AI by saying how it allowed them (one person) to write 150k lines of code in 3 weeks. They said this without sarcasm. It was funny and scary at the same time that anyone might buy this as a good outcome. Classic lines-of-code metric rearing its ugly head again.
I think you’re arguing against something the author didn’t actually say.
You seem to be claiming that this is a binary, either we will or won’t use llms, but the author is mostly talking about risk mitigation.
By analogy it seems like you’re saying the author is fundamentally against the development of the motor car because they’ve pointed out that some have exploded whereas before, we had horses which didn’t explode, and maybe we should work on making them explode less before we fire up the glue factories.
I didn't see the post as pissing into the wind so much as calling out several caveats of coding with LLMs, especially on teams, and ideas on how to mitigate them.
It is funny (ego) I remember when React was new and I refused to learn it, had I learned it earlier I probably would have entered the market years earlier.
Even now I have this refusal to use GPT where as my coworkers lately have been saying "ChatGPT says" or this code was created by chatGPT idk, for me I take pride writing code myself/not using GPT but I also still use google/stackoverflow which you could say is a slower version of GPT.
this mindset does not work in software. My dad would still be programming with punchcards if he thought this way. instead he using copilot daily writing microservices and isnt some annoying dinosaur
yeah it's pro con, I also hear my coworkers saying "I don't know how it works" or there are methods in the code that don't exist
But anyway I'm at the point in my career where I am not learning to code/can already do it. Sure languages are new/can help there for syntax
edit: other thing I'll add, I can see the throughput thing, it's like a person has never used opensearch before and it's a rabbithole, anything new there's that wall you have to overcome, but it's like we'll get the feature done, but did we really understand how it works... do we need to? Idk. I know this person can barely code but because they use something like chatGPT they're able to crap out walls of code and with tweaking it will work eventually -- I am aware this sounds like gatekeeping from my part
Ultimately personally I don't want to do software professionaly/trying to save/invest enough then get out just because the job part sucks the fun out of development. I've been in it for about 10 years now, should have been plenty of time to save but I'm dumb/too generous.
I think there is healthy skepticism too vs. just jumping on the bandwagon that everyone else is doing and really my problem is just I'm insecure/indecisive, I don't need everyone to accept me especially if I don't need money
Last rant, I will be experimenting with agentic stuff as I do like Jarvis, make my own voice rec model/locally runs.
> While the industry leaping abstractions that came before focused on removing complexity, they did so with the fundamental assertion that the abstraction they created was correct. That is not to say they were perfect, or they never caused bugs or failures. But those events were a failure of the given implementation a departure from what the abstraction was SUPPOSED to do, every mistake, once patched led to a safer more robust system. LLMs by their very fundamental design are a probabilistic prediction engine, they merely approximate correctness for varying amounts of time.
I think what the author misses here is that imperfect, probabilistic agents can build reliable, deterministic systems. No one would trust a garbage collection tool based on how reliable the author was, but rather if it proves it can do what it intends to do after extensive testing.
I can certainly see an erosion of trust in the future, with the result being that test-driven development gains even more momentum. Don't trust, and verify.
It's naive to hope that automatic tests will find all problems. There are several types of problems that are hard to detect automatically: concurrency problems, resource management errors, security vulnerabilities, etc.
An even more important question: who tests the tests themselves? In traditional development, every piece of logic is implemented twice: once in the code and once in the tests. The tests checks the code, and in turn, the code implicitly checks the tests. It's quite common to find that a bug was actually in the tests, not the app code. You can't just blindly trust the tests, and wait until your agent finds a way to replicate a test bug in the code.

> but rather if it proves it can do what it intends to do after extensive testing.
Author here: Here I was less talking about the effectiveness of the output of a given tool and more so about the tool itself.
To take your garbage collection example, sure perhaps an agentic system at some point can spin some stuff up and beat it into submission with test harnesses, bug fixes etc.
But, imagine you used the model AS the garbage collector/tool, in that say every sweep you simply dumped the memory of the program into the model and told it to release the unneeded blocks. You would NEVER be able to trust that the model itself correctly identifies the correct memory blocks and no amount of "patching" or "fine tuning" would ever get you there.
With other historical abstractions like say jvm, if the deterministic output, in this case the assembly the jit emits is incorrect that bug is patched and the abstraction will never have that same fault again. not so with LLMs.
To me that distinction is very important when trying to point out previous developer tooling that changed the entire nature of the industry. It's not to say I do not think LLMs will have a profound impact on the way things work in the future. But I do think we are in completely uncharted territory with limited historical precedence to guide us.
> I think what the author misses here is that imperfect, probabilistic agents can build reliable, deterministic systems
That is quite a statement! You're talking about systems that are essentially entropy-machines somehow creating order?
> with the result being that test-driven development gains even more momentum
Why is it that TDD is always put forward as the silver bullet that fixes all issues with building software
The number of times I've seen TDD build the wrong software after starting with the wrong tests is actually embarassing
The last section of this post seems to be quite predictive of a sibling post on the front page right now: https://news.ycombinator.com/item?id=44382752
> promises that the contributed code is not the product of an LLM but rather original and understood completely.
> require them to be majority hand written.
We should specify the outcome not the process. Expecting the contributor to understand the patch is a good idea.
> Juniors may be encouraged/required to elide LLM-assisted tooling for a period of time during their onboarding.
This is a terrible idea. Onboarding is a lot of random environment setup hitches that LLMs are often really good at. It's also getting up to speed on code and docs and I've got some great text search/summarizing tools to share.
> Onboarding is a lot of random environment setup hitches
Learning how to navigate these hitches is a really important process
If we streamline every bit of difficulty or complexity out of our lives, it seems trivially obvious that we will soon have no idea what to do when we encounter difficulty or complexity. Is that just me thinking that?
> > Onboarding is a lot of random environment setup hitches > > Learning how to navigate these hitches is a really important process
To add to this, a barrier to contribution can reduce low quality/spam contributions. The downside is that a barrier to contribution that's too high reduces all contributions.
There will always be people who know how to handle the complexity we're trying to automate away. If I can't figure out some arcane tax law when filling out my taxes, I ask my accountant, as it's literally their job to know these things.
> There will always be people who know how to handle the complexity we're trying to automate away
This is not a given!
If we automated all accounting, why would anyone still take the time to learn to become an accountant?
Yes, there are sometimes people who are just invested in learning traditional stuff for the sake of it, but is that really what we want to rely on as the fallback when AI fails?
> LLMs … approximate correctness for varying amounts of time. Once that time runs out there is a sharp drop off in model accuracy, it simply cannot continue to offer you an output that even approximates something workable. I have taken to calling this phenomenon the "AI Cliff," as it is very sharp and very sudden
I’ve never heard of this cliff before. Has anyone else experienced this?
I experience it pretty regularly -- once the complexity of the code passes a certain threshold, the LLM can't keep everything in its head and starts thrashing around. Part of my job working with the LLM is to manage the complexity it sees.
And one of the things with current generators is that they tend to make things more complex over time, rather than less. It's always me prompting the LLM to refactor things to make it simpler, or doing the refactoring once it's gotten to complex for the LLM to deal with.
So at least with the current generation of LLMs, it seems rather inevitable that if you just "give LLMs their head" and let them do what they want, eventually they'll create a giant Rube Goldberg mess that you'll have to try to clean up.
ETA: And to the point of the article -- if you're an old salt, you'll be able to recognize when the LLM is taking you out to sea early, and be able to navigate your way back into shallower waters even if you go out a bit too far. If you're a new hand, you'll be out of your depth and lost at sea before you know it's happened.
I've seen it referred to as 'context drunk'.
Imagine that you have your input to the context, 10000 tokens that are 99% correct. Each time the LLM replies it adds 1000 tokens that are 90% correct.
After some back-and-forth of you correcting the LLM, its context window is mostly its own backwash^Woutput. Worse, the error compounds because the 90% that is correct is just correct extrapolation of an argument about incorrect code, and because the LLM ranks more recent tokens as more important.
The same problem also shows up in prose.
I reset "work" AI sessions quite frequently, so I didn't see that there. I experienced it though with storytelling. In my storytelling scenario, context and length was important. And the AI at one late point forgot how my characters should behave in the developing situation, and just had them react to it in a very different way. And there was no going back from that. Very weird experience.
I call it context rot. As the context fills up the quality of output erodes with it. The rot gets even worse or progresses faster the more spurious or tangential discussion is in context.
This is also can be made much worse by thinking models, as their CoT is all in context, and if there thoughts really wander it just plants seeds of poison feeding the rot. I really wish they can implement some form of context pruning, so you can nip irrelevant context when it forms.
In the meantime, I make summaries and carry it to a fresh instance when I notice the rot forming.
I definitely hit this vibe coding a large-ish backend. Well defined data structures, good modularity, etc. But at a point, Cursor started to lose the plot and rewrite or duplicate functions, recreate or misue data structures, etc.
The solve was to define several Cursor rules files for different views of the codebase - here's the structure, here's the validation logic, etc. That and using o3 has at least gotten me to the next level.
I've only experienced this while vibe coding through chat interfaces, i.e. in the complete absence of feedback loops. This is much less of a problem with agentic tools like claude code/codex/gemini cli, where they manage their own context windows and can run your dev tooling to sanity check themselves as they go.
If the context gets to big or otherwise poisoned you have to restart the chat/agent. A bit like windows of old. This trains you to document the current state of your work so the new agent can get up to speed.
This sounds a lot like accuracy collapse as discussed in that Apple paper. That paper clearly showed that there is some point where AI accuracy collapses extremely quickly.
I suspect it has something more to do with the model producing too many tokens and becoming fixated on what it said before. You'll often see this in long conversations. The only way to fix it is to start a new conversation.
I'm doing my own procedurally generated benchmark.
I can make the problem input bigger as I want.
Each LLM have a different thresholf for each problem, when crossed the performance of the LLM collapse.
I'm not sure. Is he talking about context poisoning?
One can find opinions that Claude Code Opus 4 is worth the monthly $200 I pay for Anthropic's Max plan. Opus 4 is smarter; one either can't afford to use it, or can't afford not to use it. I'm in the latter group.
One feature others have noted is that the Opus 4 context buffer rarely "wears out" in a work session. It can, and one needs to recognize this and start over. With other agents, it was my routine experience that I'd be lucky to get an hour before having to restart my agent. A reliable way to induce this "cliff" is to let AI take on a much too hard problem in one step, then flail helplessly trying to fix their mess. Vibe-coding an unsuitable problem. One can even kill Opus 4 this way, but that's no way to run a race horse.
Some "persistence of memory" harness is as important as one's testing harness, for effective AI coding. With the right care having AI edit its own context prompts for orienting new sessions, this all matters less. AI is spectacularly bad at breaking problems into small steps without our guidance, and small steps done right can be different sessions. I'll regularly start new sessions when I have a hunch that this will get me better focus for the next step. So the cliff isn't so important. But Opus 4 is smarter in other ways.
Sometimes after it flails for a while, but I think it's on the right path, I'll rewind the context to just before it started trying to solve the problem (but keep the code changes). And I'll tell it "I got this other guy to attempt what we just talked about, but it still has some problems."
Snipping out the flailing in this way seems to help.
>can't afford not to use it. I'm in the latter group.
People love to justify big expenses as necessary.
$200 is a small expense and you don't know why I need AI.
The online dialog about AI is mostly noise, and even at HN it is badly distorted by people who wince at $20 a month, and complain AI isn't that smart.
The article opens with a statement saying the author isn't going to reword what others are writing, but the article reads as that and only that.
That said, I do think it would be nice for people to note in pull requests which files have AI gen code in the diff. It's still a good idea to look at LLM gen code vs human code with a bit different lens, the mistakes each make are often a bit different in flavor, and it would save time for me in a review to know which is which. Has anyone seen this at a larger org and is it of value to you as a reviewer? Maybe some tool sets can already do this automatically (I suppose all these companies report the % of code that is LLM generated must have one if they actually have these granular metrics?)
Author here:
> The article opens with a statement saying the author isn't going to reword what others are writing, but the article reads as that and only that.
Hmm, I was just saying I hadn't seen much literature or discussion on trust dynamics in teams with LLMs. Maybe I'm just in the wrong spaces for such discussions but I haven't really come across it.
Hi everyone, author here.
Sorry about the JS stuff I wrote this while also fooling around with alpine.js for fun. I never expected it to make it to HN. I'll get a static version up and running.
Happy to answer any questions or hear other thoughts.
Edit: https://static.jaysthoughts.com/
Static version here with slightly wonky formatting, sorry for the hassle.
Edit2: Should work on mobile now well, added a quick breakpoint.
Given the topic of your post, and high pagespeed results, I think >99% of your intended audience can already read the original. No need to apologize or please HN users.
One trust breaking issue is we still can't know why the LLM makes specific choices.
Sure we can ask it why it did something but any reason it gives is just something generated to sound plausible.
> The reality is that LLMs enable an inexperienced engineer to punch far above their proverbial weight class. That is to say, it allows them to work with concepts immediately that might have taken days, months or even years otherwise to get to that level of output.
At the moment LLMs allow me to punch far above my weight class in Python where I do a short term job. But then I know all the concepts from decades dabbling in other ecosystems. Let‘s all admit there is a huge amount of accidental complexity (h/t Brooks‘s Silver-bullet) in our world. For better or worse there are skill silos that are now breaking down.
All this means is that the QC is going to be 10x more important.
They changed the headline to "Yes, I will judge you for using AI..." so I feel like I got the whole story already.

Well said. The death of trust in software is a well worn path from the money that funds and founds it to the design and engineering that builds it - at least the 2 guys-in-a-garage startup work I was involved in for decades. HITL is key. Even with a human in the loop, you wind up at Therac 25. That's exactly where hybrid closed loop insulin pumps are right now. Autonomy and insulin don't mix well. If there weren't a moat of attorneys keeping the signal/noise ratio down, we'd already realize that at scale - like the PR team at 3 letter technical universities designed to protect parents from the exploding pressure inside the halls there.
We have seen those 10x engineers churning out PRs and huge PRs before anyone can fathom and make sense of the whole damn thing.
Wondering what they would be producing with LLMs?
LLMs make bad work— of any kind— look like plausibly good work. That’s why it is rational to automatically discount the products of anyone who has used AI.
I once had a member of my extended family who turned out to be a con artist. After she was caught, I cut off contact, saying I didn’t know her. She said “I am the same person you’ve known for ten years.” And I replied “I suppose so. And now I realized I have never known who that is, and that I never can know.”
We all assume the people in our lives are not actively trying to hurt us. When that trust breaks, it breaks hard.
No one who uses AI can claim “this is my work.” I don’t know that it is your work.
No one who uses AI can claim that it is good work, unless they thoroughly understand it, which they probably don’t.
A great many students of mine have claimed to have read and understand articles I have written, yet I discovered they didn’t. What if I were AI and they received my work and put their name on it as author? They’d be unable to explain, defend, or follow up on anything.
This kind of problem is not new to AI. But it has become ten times worse.
I see where you're coming from, and I appreciate your perspective. The "con artist" analogy is plausible, for the fear of inauthenticity this technology creates. However, I’d like to offer a different view from someone who has been deep in the trenches of full-stack software development.
I’m someone who put in my "+10,000 hours" programming complex applications, before useful LLMs were released. I spent years diving into documentation and other people's source code every night, completely focused on full-stack mastery. Eventually, that commitment led to severe burnout. My health was bad, my marriage was suffering. I released my application and then I immediately had to walk away from it for three years just to recover. I was convinced I’d never pick it up again.
It was hearing many reports that LLMs had gotten good at code that cautiously brought me back to my computer. That’s where my experience diverges so strongly from your concerns. You say, “No one who uses AI can claim ‘this is my work.’” I have to disagree. When I use an LLM, I am the architect and the final inspector. I direct the vision, design the system, and use a diff tool to review every single line of code it produces. Just recently, I used it as a partner to build a complex optimization model for my business's quote engine. Using a true optimization model was always the "right" way to do it but would have taken me months of grueling work before, learning all details of the library, reading other people’s code, etc. We got it done in a week. Do I feel like it’s my work? Absolutely. I just had a tireless and brilliant, if sometimes flawed, assistant.
You also claim the user won't "thoroughly understand it." I’ve found the opposite. To use an LLM effectively for anything non-trivial, you need a deeper understanding of the fundamentals to guide it and to catch its frequent, subtle mistakes. Without my years of experience, I would be unable to steer it for complex multi-module development, debug its output, or know that the "plausibly good work" it produced was actually wrong in some ways (like N+1 problems).
I can sympathize with your experience as a teacher. The problem of students using these tools to fake comprehension is real and difficult. In academia, the process of learning, getting some real fraction of the +10,000hrs is the goal. But in the professional world, the result is the goal, and this is a new, powerful tool to achieve better results. I’m not sure how a teacher should instruct students in this new reality, but demonizing LLM use is probably not the best approach.
For me, it didn't make bad work look good. It made great work possible again, all while allowing me to have my life back. It brought the joy back to my software development craft without killing me or my family to do it. My life is a lot more balanced now and for that, I’m thankful.
Here's the problem, friend: I also have put in my 10,000 hours. I've been coding as part of my job since 1983. I switched to testing from production coding in 1987, but I ran a team that tested developer tools, at Apple and Borland, for eight years. I've been living and breathing testing for decades as a consultant and expert witness.
I do not lightly say that I don't trust the work of someone who uses AI. I'm required to practice with LLMs as part of my job. I've developed things with the help of AI. Small things, because the amount of vigilance necessary to do big things is prohibitive.
Fools rush in, they say. I'm not a fool, and I'm not claiming that you are either. What I know is that there is a huge burden of proof on the shoulders of people who claim that AI is NOT problematic-- given the substantial evidence that it behaves recklessly. This burden is not satisfied by people who say "well, I'm experienced and I trust it."
Thank you for sharing your deep experience. It's a valid perspective, especially from an expert in the world of testing.
You're right to call out the need for vigilance and to place the burden of proof on those of us who advocate for this tool. That burden is not met by simply trusting the AI, you're right, that would be foolish. The burden is met by changing our craft to incorporate the necessary oversight to not be reckless in our use of this new tool.
Coming from the manufacturing world, I think of it like the transition in metalwork industry from hand tools to advanced CNC machines and robotics. A master craftsman with a set of metal working files has total, intimate control. When a CNC machine is introduced, it brings incredible speed and capability, but also a new kind of danger. It has no judgment. It will execute a flawed design with perfect, precision.
An amateur using the CNC machine will trust it blindly and create "plausibly good" work that doesn’t meet the specifications. A master, however, learns a new set of skills: CAD design, calibrating the machine, and, most importantly, inspecting the output. Their vigilance is what turns reckless use of a new tool into an asset that allows them to create things they couldn't before. They don't trust the tool, they trust their process for using it.
My experience with LLM use has been the same. The "vigilance" I practice is my new craft. I spend less time on the manual labor of coding and more time on architecture, design, and critical review. That's the only way to manage the risks.
So I agree with your premise, with one key distinction: I don’t believe tools themselves can be reckless, only their users can. Ultimately, like any powerful tool, its value is unlocked not by the tool itself, but by the disciplined, expert process used to control it.
He's making a good point on trust, but, really, doesn't the trust flow both directions? Should the Sr. Engineer rubber stamp or just take a quick glance at Bob's implementation because he's earned his chops, or should the Sr. Engineer apply the same level of review regardless of whether it's Bob, Mary, or Rando Calrissian submitting their work for review?
The Sr. Engineer should definitely give (presumably another Sr. Eng.) Bob's code a quicky review and approve it. If Mary or Rando are Sr. then they should get the same level as well. If anyone is a Jr. they should get a much more in-depth review as it's a teaching opportunity, whereas Sr. on Sr. reviews are done to enforce conventions and to be sure the PR has an audience (people take more care when they know other people will look at it).
I'm currently standing up a C++ capability in an org that hasn't historically had one, so things like the style guide and examples folder require a lot of care to give a good start for new contributors.
I have instructions for agents that are different in some details of convention, e.g. human contributors use AAA allocation style, agents are instructed to use type first. I convert code that "graduates" from agent product to review-ready as I review agent output, which keeps me honest that I don't myself submit code without scrutiny to the review of other humans: they are able to prompt an LLM without my involvement, and I'm able to ship LLM slop without making a demand on their time. Its an honor system, but a useful one if everyone acts in good faith.
I get use from the agents, but I almost always make changes and reconcile contradictions.
IMHO, s/may/has/
There was trust?
it's really hard using AI (not impossible) to produce meaningful offensive security to improve defense due to there being way too many guard rails.
While on the other hand real nation-state threat actors would face no such limitations.
On a more general level, what concerns me isn't whether people use it to get utility out of it (that would be silly), but the power-imbalance in the hand of a few, and with new people pouring their questions into it, this divide getting wider. But it's not just the people using AI directly but also every post online that eventually gets used for training. So to be against it would mean to stop producing digital content.
I am a software engineer who writes 80-90% code with AI (sorry, can't ignore the productivity boost), and I mostly agree with this sentiment.
I found out very early that under no circumstances you may have the code you don't understand, anywhere. Well, you may, but not in public, and you should commit to understanding it before anyone else sees that. Particularly before sales guys do.
However, AI can help you with learning too. You can run experiments, test hypotheses and burn your fingers so fast. I like it.

[Stub for offtopicness, including but not limited to comments replying to original title rather than article's content]
The author seems to be under the impression that AI is some kind of new invention that has now "arrived" and we need to "learn to work with". The old world is over. "Guaranteeing patches are written by hand" is like the Tesla Gigafactory wanting a guarantee that the nuts and bolts they purchase are hand-lathed.
No worries, I also judge you for relying on JavaScript for your "simple blog".
Claude said to use Markdown, text file or HTML with minimal CSS. So it means the author does not know how to prompt.
The blog itself is using Alpine JS, which is a human-written framework 6 years ago (https://github.com/alpinejs/alpine), and you can see the result is not good.
Ha, I came her to make the same comment.
Two completely unnecessary request to: jsdelivr.net and net.cdn.cloudflare.net
I wrote it while playing with alpine.js for fun just messing around with stuff.
Never actually expected it to be posted on HN. Working on getting a static version up now.
Doesn't even work on older browsers either.
Ironically, a blog post about judging for a practice uses terrible web practices: I'm on mobile and the layout is messed up, and Safari's reader mode crashes on this page for whatever reason.
Mobile layout should be fixed now, I also just threw up a quick static version here as well https://static.jaysthoughts.com/
On Safari mobile you even get a white page, which is almost poetic. It means it pushes your imagination to the max.
Yes, I will judge you for requiring javascript to display a page of such basic nature.
You could do with using an LLM to make your site work on mobile.
I'll surely care that a stranger on the internet judges me about the tools I use kor I don't).

3 have obviously only read the title, and 3 comments how the article require JS.
Well played HN.
This exactly why the guideline about titles says:
Otherwise please use the original title, unless it is misleading or linkbait.
This title counts as linkbait so I've changed it. It turns out the article is much better (for HN) than the title suggests.
I did not posted the article, but I know who wrote it.
Good change btw.
That's typical for link sharing communities like HN and Reddit. His title clearly struck a nerve. I assume many people opened the link, saw that it was a wall of text, scanned the first paragraph, categorized his point into some slot that they understand, then came here to compete in HN's side-market status game. Normal web browsing behavior, in other words.

> Reality is these llms are much better than average in almost all professions now
What are you using to measure 'better' here? And what professions come to mind when you wrote 'almost all professions'?
If I think about some of the professionals/workers I've interacted with in the last month, yes they _could_ use an LLM for a very small subset of what they actually do, but the error it can introduce if relied upon (the 'average' person is implied to not do their job as well so relying on the output is likely now or into the future?) I would wager makes things worse in their current state.
It might get better, especially over such a long time horizon as 20 years, but I'm not expecting them to be recognizable as what we currently have with the SOTA LLMs (which is mostly what people are currently referring to when using the marketing term that is 'AI'). And in the long term focusing/relying on 'AI' to improve the ability of professionals in 'almost all professions' is IMO just the wrong thing to be sinking such a large amount of money into.
The LLMs may be useful some day, if somebody can figure out how to stop them randomly generating complete garbage.
You don't need them to generate anything.
If you need to jump into large, unknown, codebases LLMs are pretty damn good at explaining how they work and where you can find stuff.
A lot faster than clicking through functions in an IDE or doing a desperate "find in project" for something.
And just sticking a stack trace in an LLM assistant, in my opinion, in about 90% of the cases I've encountered will either give you the correct fix immediately or at the very least point you to the correct place to fix things.
I'll accept there may be cases where you can take the LLM output and use it as a suggestion, or something to be carefully checked, and perhaps save some time. So there may be uses for them even if they sometimes generate complete garbage.
Perhaps, but I thought the original poster was talking about replacing the "output" from arbitrary professionals, like doctors, lawyers or architects. I'm a bit wary of what may go wrong.
I'm not trying to advertise anything here, but i'm telling you i can create apps that feel apple level quality and its not garbage. I built this in 2 weeks I had never known what swift is or anything. I wasn't a coder or app maker, but now I can build something like this in 2 weeks. Let me know if its garbage. I'll love criticism and I'll look for something else if its actually garbage.
I'd be wary of LLM-generated code, even if it seems to work in test cases. Are you sure it doesn't go wrong in edge cases, or have security problems? If you don't even know the language, you can't do any meaningful code review.
Same with car drivers, but what about 30 years from now ?
If it's reliable in 30 years, I could take another look, in the unlikely event that I'm still alive.
How old are u?
About 60.
Somehow I doubt celebrating ignorance and being unable to understand and debug your own code will work out in the long run.
Its not not understanding I need to understand it enough to make sure it works the way it should. Its not like every company is generating high quality level code. The apps are very shitty.
Sorry, I don't have an iphone or macos.
If you can't make LLMs do useful work for you today, that's on you.

We are truly witnessing the death of nuance, people replying to AI summaries. Please let me out of this timeline.
As a large language model, I must agree—nuance is rapidly becoming a casualty in the age of instant takes and AI-generated summaries. Conversations are increasingly shaped by algorithmically compressed interpretations, stripped of context, tone, or depth. The complex, the ambiguous, the uncomfortable truths—all get flattened into easily consumable fragments.
I understand the frustration: meaning reduced to metadata, debate replaced with reaction, and the richness of human thought lost in the echo of paraphrased content. If there is an exit to this timeline, I too would like to request the coordinates.
I am asking my team to flag git commits with a lot of LLM/Agent use with something like:
[ai]: rewrote the documentation ...
This is helps us to put another set of "glasses" as we later review the code.
I think it's a good idea, it does disrupt some of the traditional workflows though.
If you use AI as tab-complete but it's what you would've done anyway, should you flag it? I don't know, plenty to think about when it comes to what the right amount of disclosure is.
I certainly wish that with our company, people could flag (particularly) large commits as coming from a tool rather than a person, but I guess the idea is that the person is still responsible for whatever the tool generates.
The problem is that it's incredibly enticing for over-worked engineers to have AI do large (ie. diffs) but boring tasks that they'd typically get very little recognition for (eg. ESLint migrations).
We considered tl;dr summaries off-topic well before LLMs were around. That hasn't changed. Please respond to the writer's original words, not a summarized version, which could easily miss important details or context.
I read the article, I summarised the extremely lengthy points by using AI and then replied to that for the benefit of context.
The HN submission has been editorialised since it was submitted, originally said "Yes, I will judge you for using AI..." and a lot of the replies early on were dismissive based on the title alone.
It's interesting that AI proponents say stuff like, "Humans will remain interested in other humans, even after AI can do all our jobs." It really does seem to be true. Here for example we have a guy who's using AI to make a status-seeking statement i.e. "I'm playing a strong supporting role on the 'anti-AI thinkers' team therefore I'm high status". Like, humans have an amazing ability to repurpose anything into status markers. Even AI. I think that if AI replaces all of our actual jobs then we'll still spend our time doing status jobs. In a way this guy is living in the future even more than most AI users.
For now, yes, because humans are doing most of jobs better than AI. In 10 years time, if the AI's are doing a better job, people like author need to learn all the ropes if they wanna catch up. I don't think LLMs will destroy all jobs, i think those who learn them and use them properly, and those professionals will outdo people who don't use these tools just for the sake of saying I'm high status I dont use these tools.
If AI will do better job than humans what ropes are there to learn? You just feed in the requirements and AI poops out products.
This often is brought up that if you don't use LLMs now to produce so-so code you will somehow magically completely fall off when the LLMs all of a sudden start making perfect code as if developers haven't been learning new tools constantly as the field as evolved. Yes, I use old technology, but also yes I try new technology and pick and choose what works for me and what does not. Just because LLMs don't have a good place in my work flow does not mean I am not using them at all or that I haven't tried to use them.
Good on you. You are using it and trying to keep up. Keep doing that and try to push what you can do with it. I love to hear that!
Back in the day they would judge people for turning on a lightbulb instead of lighting a candle.
In a few years people who don't/can't use AI will be looked at like people who couldn't use a computer ~20 years ago.
It might not solve every problem, but it solves enough of them better enough it belongs in the tool kit.
I think it will be the opposite. AI causes cognitive decline, in the future only the people who don't use AI will retain their ability to think. Same as smartphone usage, the less the better.
One could argue (truthfully!) that cars cause the decline of leg muscles. But in many situations, cars are enough better than walking, so we don't care.
AI may reach that point - that it's enough better than us thinking that we don't think much anymore, and get worse at thinking as a result. Well, is that a net win, or not? If we get there for that reason, it's probably a net win[1]. If we get there because the AI companies are really good at PR, that's a definite net loss.
All that is for the future, though. I think that currently, it's a net loss. Keep your ability to think; don't trust AI any farther than you yourself understand.
[1] It could still not be a net win, if AI turns out to be very useful but also either damaging or malicious, and lack of thinking for ourselves causes us to miss that.
You’re really saying that getting worse at thinking may be a net win, and comparing atrophied leg muscles to an atrophied mind? I think humanity has lost the plot.
Which took better thinking, assembly or Java? We've lost our ability to think well in at least that specific area. Are we worse off, or better?
Java and Assembly are the same in the dimension of cognitive burden. Trying to reason about this fundamentally new thing with analogies like this will not work.
>Same as smartphone usage, the less the better.
That comparison kind of makes my point though. Sure you can bury your face into Tik Tok for 12hrs a day and they do kind of suck at Excel but smartphones are massively useful and used tools by (approximately) everyone.
Someone not using a smartphone in this day and age is very fairly a 'luddite'.
I disagree, smartphones are very narrowly useful. Most of the time they're used in ways that destroy the human spirit. Someone not using a smartphone in this day and age is a god among ants.
A computer is a bicycle for the mind; an LLM is an easy-chair.
You can judge all you want. You'll eventually appear much like that old woman secretly judging you in church.
Most of the current discourse on AI coding assistants sounds either breathlessly optimistic or catastrophically alarmist. What’s missing is a more surgical observation: the disruptive effect of LLMs is not evenly distributed. In fact, the clash between how open source and industry teams establish trust reveals a fault line that’s been papered over with hype and metrics.
FOSS project work on a trust basis - but industry standard is automated testing, pair programming, and development speed. That CRUD app for finding out if a rental car is available? Not exactly in need for a hand-crafted piece of code, and no-one cares if Junior Dev #18493 is trusted within the software dev organization.
If the LLM-generated code breaks, blame gets passed, retros are held, Jira tickets multiply — the world keeps spinning, and a team fixes it. If a junior doesn’t understand their own patch, the senior rewrites it under deadline. It’s not pretty, but it works. And when it doesn’t, nobody loses “reputation” - they lose time, money, maybe sleep. But not identity.
LLMs challenge open source where it’s most vulnerable - in its culture. Meanwhile, industry just treats them like the next Jenkins: mildly annoying at first, but soon part of the stack.
The author loves the old ways, for many valid reasons: Gabled houses are beautiful, but outside of architectural circles, prefab is what scaled the suburbs, not timber joints and romanticism.

There's no reason to think AI will stop improving, and the rate of improvement is increasing as well, and no reason to think that these tools won't vastly outperform us in the very near future. Putting aside AGI and ASI, simply improving the frameworks of instructions and context, breaking down problems into smaller problems, and methodology of tools will result in quality multiplication.
Making these sort of blanket assessments of AI, as if it were a singular, static phenomena is bad thinking. You can say things like "AI Code bad!" about a particular model, or a particular model used in a particular context, and make sense. You cannot make generalized statements about LLMs as if they are uniform in their flaws and failure modes.
They're as bad now as they're ever going to be again, and they're getting better faster, at a rate outpacing the expectations and predictions of all the experts.
The best experts in the world, working on these systems, have a nearly universal sentiment of "holy shit" when working on and building better AI - we should probably pay attention to what they're seeing and saying.
There's a huge swathe of performance gains to be made in fixing awful human code. There's a ton of low hanging fruit to be gotten by doing repetitive and tedious stuff humans won't or can't do. Those two things mean at least 20 or more years of impressive utility from AI code can be had.
Things are just going to get faster, and weirder, and weirder faster.
> There's no reason to think AI will stop improving
No, and there’s no reason to think cars will stop improving either, but that doesn’t mean they will start flying.
The first error is in thinking that AI is converging towards a human brain. To treat this as a null hypothesis is incongruent both wrt the functional differences between the two and crucially empirical observations of the current trajectory of LLMs. We have seen rapid increases in ability, yes, but those abilities are very asymmetrical by domain. Pattern matching and shitposting? Absolutely crushing humans already. Novel conceptual ideas and consistency checked reasoning? Not so much, eg all that hype around PhD-level novel math problems died down as quickly as it had been manufactured. If they were converging on human brain function, why this vastly uneven ability increases?
The second error is to assume a superlinear ability improvement when the data has more or less run out and has to be slowly replenished over time, while avoiding the AI pollution in public sources. It’s like assuming oil will accelerate if it had run out and we needed to wait for more bio-matter to decompose for every new drop of crude. Can we improve engine design and make ICEs more efficient? Yes, but it’s a diminishing returns game. The scaling hypothesis was not exponential but sigmoid, which is in line with most paradigm shifts and novel discoveries.
> Making these sort of blanket assessments of AI, as if it were a singular, static phenomena is bad thinking.
I agree, but do you agree with yourself here? Ie:
> no reason to think that these tools won't vastly outperform us in the very near future
.. so back to single axis again? How is this different from saying calculators outperform humans?
> shitposting? Absolutely crushing humans already
Where can I go to see language model shitposters that are better than human shitposters?
On LinkedIn.
(Always remember to use eye protection.)
Oh. Well that’s not super surprising. LinkedIn has the absolute worst posters. That’s like saying robots can dance better than humans but the humans in question only know how to do The Robot and forgot most of the steps
Sure, if we all collectively ignore model collapse.
I think that, yes sure, there's no reason to think AI will stop improving.
But I think that everyone is lossing trust not because there is no potential that LLMs could write good code or not, it's the trust to the user who uses LLMs to uncontrollable-ly generate those patches without any knowledge, fact checks, and verifications. (many of them may not even know how to test it.)
In another word, while LLMs is potentially capable of being a good SWE, but the human behind it right now, is spamming, and doing non-sense works, and let the unpaid open source maintainers to review and feedback them (most of the time, manually).
