An analysis of 23,000 AI-generated pull requests found that inexperienced developers opened 2x more PRs than experienced ones, with PRs 2x bigger on average. But the junior devs' PRs:
- generated 4x the review comments
- were 31% less likely to be accepted
- took 5x longer to resolve
The poster's takeaway: AI doesn't close the gap between people who know what they're doing and people who don't.
