I've been asked to look at codebases created by people without programming skills using AI. They ask me to just fix this one little thing, it's perfect otherwise. But it's not perfect otherwise, the more you look, the more issues you can spot. I've never accepted to even begin work on such a codebases, they should be nuked from orbit, only way to be sure.

We used to have this joke, where somebody said they got the code from StackOverflow and we would ask "From the question or the answer?". All the current models have been trained on sources like StackOverflow and probably won't weigh the -10.000 down voted answer any different from the actual good answer, if there ever was a good answer to begin with.

Big assumption that they're actually going to try and fix the mess rather than declare that the system doesn't work and scrap the whole thing.
