AI produces code quicker, and code review is the bottleneck now. Anecdotally AI hasn't helped as much with the latter, especially for 'important' pull requests. A junior engineer can now generate code faster than a senior engineer can critically audit it.
Code review is important for sharing knowledge and understanding. Even more so now due to things like [[20260625104409-comprehension-debt]]. Making pull requests as small as possible is even more important now.
