My AI code reviewer is nicer than my coworkers — and that worries me

I submitted a PR with a pretty messy refactor. My human teammates took 3 days to comment — and the comments were rough. I fed the same diff to an AI tool. Got instant line-by-line feedback in 10 seconds, polite and constructive.

I ran the experiment three more times with different PRs. Each time: AI was faster (seconds vs days), more thorough (caught edge cases humans missed), and dramatically more polite. But here’s the thing: AI review is great at local correctness. It struggles with contextual judgment. What scares me is not that AI will replace code review. It’s that teams might start relying on AI review first and human review never.
