> LLM being used to make code more simple and elegant

Simple and elegant generally doesn't come from the LLM. It comes from me saying no to the LLM. I've discarded many branches that didn't feel like they were going the right way. Hell, I aggressively do that with my own code also. I rarely commit the first thing that works.

> where are the open source examples?

My general impression of open source is that it is, in part, a market driven by good software engineering. There's certainly below average code, but that tends to get mocked out of existence before it grows too much. Proprietary code that doesn't have a strong forcing function used to be able to hide poor engineering principles.

I think AI generated code is a regression to the mean, and the mean can be an improvement sometimes. I inherited this project. It was not originally written with AI. A lot of hard work and good engineering went into the hardware/firmware. The IoT software connecting it to our intranet, less so. Some examples that I'm fixing/fixed: ignoring HTTPS certificates, RCE by design, in-place file updating JSON files, a hand-rolled (but ineffective) fair mutex, busy waiting for a device to appear, and worst of all, no tests. None of these are hard to avoid, and even the small AI models would have come up with a better implementation.

This doesn't seem unique to my project either. I think a lot of software is just silently getting closer to the average of all open source code upon which the models were trained. I don't think I want things like SQLite to get closer to the average.

> Fully leaning into LLM doing as much of the coding and understanding as can be handed off to them seems insane to me, I don't mean this to offend though.

I think you might be reading too much into what I said. When I say "fully lean into", it's probably less than you're thinking of. I still feel that I understand what was written and can stake my reputation/career on it.
