We keep human review because AI coding is not yet good enough. We use though an AI reviewer first, before the human even see the PR, that helps us filtering most of the bad code details so human don't lose time and focus on important things. Be careful though when choosing an AI reviewer, and never use claude/codex directly for this, they will just add noisy comments and instead of helping humans will just add more work to filter which are good and which are just noise.
