I think it depends a little on how and where you work. In the energy industry of Europe where we are extremely regulated AI has been writing some excellent and maintainable code. Of course we can't do any of that CLEAN SOLID DRY stuff, or any abstraction and implicity really, and I imagine that AI would struggle with that. Though you have to wonder if any of those religions ever really worked when you consider that they've still failed to replace most COBOL systems 30 years later. Anyway, that's a different discussion and even Uncle Bob has moved on to functional programming.

I've yet to have Opus 4.8 fail me with defensive explict code. Often it'll write code that is better than what I might have done. I imagine it would be a nightmare to go through one of the OOP debug chains with implict error handling, but when every function has a runtime assertion which is basically the contract for how it is supposed to work and exactly what to do if it encounters a corrupt state, then things are just so much easier with AI.

I do agree with you on documentation. The amount we have has exploded in the post AI world. Which is a little ironic since the assertion is frankly what you'll need to know and not the 10 pages of prose the AI autogenerated in the shared loop (microsoft's terrible confluence). It is what it is though, and at least it's easier to meet EU compliance rules now, since those are more about the bureaucracy than actual security.
