Something I've noticed is that AI code generation makes it easier/faster to generate code while shifting more work of the work of keeping code correct and maintainable to the code review stage. That can be highly problematic for open source projects that are typically already bottlenecked by maintainer review bandwidth.
It can be mitigated by PR submitters doing a review and edit pass prior to submitting a PR. But a lot of submitters don't currently do this, and in my experience the average quality of PRs generated by AI is definitely significantly lower than those not generated by AI.
