Just want to clarify, this is not my Substack, I’m just sharing this because I found it insightful.
The author describes himself as a “fractional CTO”(no clue what that means, don’t ask me) and advisor. His clients asked him how they could leverage AI. He decided to experience it for himself. From the author(emphasis mine):
I forced myself to use Claude Code exclusively to build a product. Three months. Not a single line of code written by me. I wanted to experience what my clients were considering—100% AI adoption. I needed to know firsthand why that 95% failure rate exists.
I got the product launched. It worked. I was proud of what I’d created. Then came the moment that validated every concern in that MIT study: I needed to make a small change and realized I wasn’t confident I could do it. My own product, built under my direction, and I’d lost confidence in my ability to modify it.
Now when clients ask me about AI adoption, I can tell them exactly what 100% looks like: it looks like failure. Not immediate failure—that’s the trap. Initial metrics look great. You ship faster. You feel productive. Then three months later, you realize nobody actually understands what you’ve built.
The developers can’t debug code they didn’t write.
This is a bit of a stretch.
agreed. 50% of my job is debugging code I didn’t write.
We’re about to face a crisis nobody’s talking about. In 10 years, who’s going to mentor the next generation? The developers who’ve been using AI since day one won’t have the architectural understanding to teach. The product managers who’ve always relied on AI for decisions won’t have the judgment to pass on. The leaders who’ve abdicated to algorithms won’t have the wisdom to share.
Except we are talking about that, and the tech bro response is “in 10 years we’ll have AGI and it will do all these things all the time permanently.” In their roadmap, there won’t be a next generation of software developers, product managers, or mid-level leaders, because AGI will do all those things faster and better than humans. There will just be CEOs, the capital they control, and AI.
What’s most absurd is that, if that were all true, that would lead to a crisis much larger than just a generational knowledge problem in a specific industry. It would cut regular workers entirely out of the economy, and regular workers form the foundation of the economy, so the entire economy would collapse.
“Yes, the planet got destroyed. But for a beautiful moment in time we created a lot of value for shareholders.”
Yep, and now you know why all the tech companies suddenly became VERY politically active. This future isn’t compatible with democracy. Once these companies no longer provide employment their benefit to society becomes a big fat question mark.
I cannot understand and debug code written by AI. But I also cannot understand and debug code written by me.
Let’s just call it even.
FYI this article is written with a LLM.
Don’t believe a story just because it confirms your view!
I’ve heard that these tools aren’t 100% accurate, but your last point is valid.
“fractional CTO”(no clue what that means, don’t ask me)
For those who were also interested to find out: Consultant and advisor in a part time role, paid to make decisions that would usually fall under the scope of a CTO, but for smaller companies who can’t afford a full-time experienced CTO
That sounds awful. You get someone who doesn’t really know the company or product, they take a bunch of decisions that fundamentally affect how you work, and then they’re gone.
… actually, that sounds exactly like any other company.
Personally I tried using LLMs for reading error logs and summarizing what’s going on. I can say that even with somewhat complex errors, they were almost always right and very helpful. So basically the general consensus of using them as assistants within a narrow scope.
Though it should also be noted that I only did this at work. While it seems to work well, I think I’d still limit such use in personal projects, since I want to keep learning more, and private projects are generally much more enjoyable to work on.
Another interesting use case I can highlight is using a chatbot as documentation when the actual documentation is horrible. However, this only works within the same ecosystem, so for instance Copilot with MS software. Microsoft definitely trained Copilot on its own stuff and it’s often considerably more helpful than the docs.
To quote your quote:
I got the product launched. It worked. I was proud of what I’d created. Then came the moment that validated every concern in that MIT study: I needed to make a small change and realized I wasn’t confident I could do it. My own product, built under my direction, and I’d lost confidence in my ability to modify it.
I think the author just independently rediscovered “middle management”. Indeed, when you delegate the gruntwork under your responsibility, those same people are who you go to when addressing bugs and new requirements. It’s not on you to effect repairs: it’s on your team. I am Jack’s complete lack of surprise. The idea that relying on AI to do nuanced work like this and arrive at the exact correct answer to the problem, is naive at best. I’d be sweating too.
They never actually say what “product” do they make, it’s always “shipped product” like they’re fucking amazon warehouse. I suspect because it’s some trivial webpage that takes an afternoon for a student to ship up, that they spent three days arguing with an autocomplete to shit out.
Something any (real, trained, educated) developer who has even touched AI in their career could have told you. Without a 3 month study.
It’s still useful to have an actual “study” (I’d rather call it a POC) with hard data you can point to, rather than just “trust me bro”.
What’s funny is this guy has 25 years of experience as a software developer. But three months was all it took to make it worthless. He also said it was harder than if he’d just wrote the code himself. Claude would make a mistake, he would correct it. Claude would make the same mistake again, having learned nothing, and he’d fix it again. Constant firefighting, he called it.
Great article, brave and correct. Good luck getting the same leaders who blindly believe in a magical trend for this or next quarters numbers; they don’t care about things a year away let alone 10.
I work in HR and was stuck by the parallel between management jobs being gutted by major corps starting in the 80s and 90s during “downsizing” who either never replaced them or offshore them. They had the Big 4 telling them it was the future of business. Know who is now providing consultation to them on why they have poor ops, processes, high turnover, etc? Take $ on the way in, and the way out. AI is just the next in long line of smart people pretending they know your business while you abdicate knowing your business or employees.
Hope leaders can be a bit braver and wiser this go 'round so we don’t get to a cliffs edge in software.
Tbh I think the true leaders are high on coke.
AI is hot garbage and anyone using it is a skillless hack. This will never not be true.
Wait so I should just be manually folding all these proteins?
Do you not know the difference between an automated process and machine learning?
The thing with being cocky is, if you are wrong it makes you look like an even bigger asshole
https://en.wikipedia.org/wiki/AlphaFold
The program uses a form of attention network, a deep learning technique that focuses on having the AI identify parts of a larger problem, then piece it together to obtain the overall solution.
Cool, now do an environmental impact on it.
Cool, now do an environmental impact on the data centre hosting your instance while you pollute by mindlessly talking shit on the Internet.
I’ll take AI unfolding proteins over you posting any day.
Hilarious. You’re comparing a lemmy instance to AI data centers. There’s the proof I needed that you have no fucking clue what you’re talking about.
“bUt mUh fOLdeD pRoTEinS,” said the AI minion.
Just ask the ai to make the change?
AI isn’t good at changing code, or really even understanding it… It’s good at writing it, ideally 50-250 lines at a time
Not immediate failure—that’s the trap. Initial metrics look great. You ship faster. You feel productive.
And all they’ll hear is “not failure, metrics great, ship faster, productive” and go against your advice because who cares about three months later, that’s next quarter, line must go up now. I also found this bit funny:
I forced myself to use Claude Code exclusively to build a product. Three months. Not a single line of code written by me… I was proud of what I’d created.
Well you didn’t create it, you said so yourself, not sure why you’d be proud, it’s almost like the conclusion should’ve been blindingly obvious right there.
The top comment on the article points that out.
It’s an example of a far older phenomenon: Once you automate something, the corresponding skill set and experience atrophy. It’s a problem that predates LLMs by quite a bit. If the only experience gained is with the automated system, the skills are never acquired. I’ll have to find it but there’s a story about a modern fighter jet pilot not being able to handle a WWII era Lancaster bomber. They don’t know how to do the stuff that modern warplanes do automatically.
So there’s actual developers who could tell you from the start that LLMs are useless for coding, and then there’s this moron & similar people who first have to fuck up an ecosystem before believing the obvious. Thanks fuckhead for driving RAM prices through the ceiling… And for wasting energy and water.
I can least kinda appreciate this guy’s approach. If we assume that AI is a magic bullet, then it’s not crazy to assume we, the existing programmers, would resist it just to save our own jobs. Or we’d complain because it doesn’t do things our way, but we’re the old way and this is the new way. So maybe we’re just being whiny and can be ignored.
So he tested it to see for himself, and what he found was that he agreed with us, that it’s not worth it.
Ignoring experts is annoying, but doing some of your own science and getting first-hand experience isn’t always a bad idea.
100% this. The guy was literally a consultant and a developer. It’d just be bad business for him to outright dismiss AI without having actual hands on experience with said product. Clients want that type of experience and knowledge when paying a business to give them advice and develop a product for them.
They are useful for doing the kind of boilerplate boring stuff that any good dev should have largely optimized and automated already. If it’s 1) dead simple and 2) extremely common, then yeah an LLM can code for you, but ask yourself why you don’t have a time-saving solution for those common tasks already in place? As with anything LLM, it’s decent at replicating how humans in general have responded to a given problem, if the problem is not too complex and not too rare, and not much else.
And then there are actual good developers who could or would tell you that LLMs can be useful for coding, in the right context and if used intelligently. No harm, for example, in having LLMs build out some of your more mundane code like unit/integration tests, have it help you update your deployment pipeline, generate boilerplate code that’s not already covered by your framework, etc. That it’s not able to completely write 100% of your codebase perfectly from the get-go does not mean it’s entirely useless.
And then there are actual good developers who could or would tell you that LLMs can be useful for coding
The only people who believe that are managers and bad developers.
You’re wrong, whether you figure that out now or later. Using an LLM where you gatekeep every write is something that good developers have started doing. The most senior engineers I work with are the ones who have adopted the most AI into their workflow, and with the most care. There’s a difference between vibe coding and responsible use.
There’s a difference between vibe coding and responsible use.
There’s also a difference between the occasional evening getting drunk and alcoholism. That doesn’t make an occasional event healthy, nor does it mean you are qualified to drive a car in that state.
People who use LLMs in production code are - by definition - not “good developers”. Because:
- a good developer has a clear grasp on every single instruction in the code - and critically reviewing code generated by someone else is more effort than writing it yourself
- pushing code to production without critical review is grossly negligent and compromises data & security
This already means the net gain with use of LLMs is negative. Can you use it to quickly push out some production code & impress your manager? Possibly. Will it be efficient? It might be. Will it be bug-free and secure? You’ll never know until shit hits the fan.
Also: using LLMs to generate code, a dev will likely be violating copyrights of open source left and right, effectively copy-pasting licensed code from other people without attributing authorship, i.e. they exhibit parasitic behavior & outright violate laws. Furthermore the stuff that applies to all users of LLMs applies:
- they contribute to the hype, fucking up our planet, causing brain rot and skill loss on average, and pumping hardware prices to insane heights.
