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.
Depending on your team of human developers (and managers), they will do the same thing. Granted, most LLMs have a rather extreme sycophancy problem, but humans often do the same.
If it’s a problem like under or over-constrained geometry or equations, they (the better ones) will tell you. For difficult programing tasks I have definitely had the AIs bark up all the wrong trees trying to fix something until I gave them specific direction for where to look for a fix (very much like my experiences with some human developers over the years.)
I had a specific task that I was developing in one model, and it was a hard problem but I was making progress and could see the solution was near, then I switched to a different model which did come back and tell me “this is impossible, you’re doing it wrong, you must give up this approach” up until I showed it the results I had achieved to-date with the other model, then that same model which told me it was impossible helped me finish the job completely and correctly. A lot like people.
