I hate that AI has made it harder to enjoy code reviews. I know it's always been a common thing to have ripped code in a PR but at least it took a tiny bit of skill to adapt it properly to the codebase.
If I see a clever (and maintainable ofc) solution in a PR now I usually just assume it was AI that wrote it. This goes the other way too, if I write some code I'm proud of, I assume my reviewers will just assume it was generated :(
