I don't see the difference there. Whether I've written all the code myself or an AI wrote all of it, my name will be on the commit. I'll be the person people turn to when they question why code is the way it is. In a pull request for my commit, I'll be the one discussing it with my colleagues. I can't say "oh, the AI wrote it". I'm responsible for the code. Full stop.

If you're in a team where somebody can continuously commit trash without any repercussions, this isn't a problem caused by AI.
