I think the real issue might be that how “good” the code is matters less than being able to form a mental model for what the human who wrote the code was “thinking”. If written by a machine, this contract is broken and we get more confused, even if our traditional methods of evaluating the code come out equal.

Yes, thank you for wording it better. When I read through for example an entire codebase that was ~99% written by AI, it's "inconsistent" in a way that even a shared-by-humans codebase would not be. I think this arises from the AI misunderstanding slightly what is being asked - the AI misunderstands, but can still (at least in some cases) output code that does what it needs to. It may also do other things that it doesn't need to do, or may do the thing in a suboptimal, not-so-maintainable way, but the UI works and that's enough for most non-technical people.
