- AI accelerates code generation, leading to more PRs, making code reviews the new bottleneck for engineering teams.
- Engineers often procrastinate on reviewing AI-generated PRs, resulting in longer PR pickup times, especially for agentic AI PRs.
- Code review is less enjoyable than building due to mental energy required, lack of direct KPIs, and responsibility concerns.
- Solutions include using AI for pre-review checks, adding comments for clarity, implementing AI code review tools, and creating test cases.
- Balancing AI and human reviews is key, with AI increasing speed but human oversight needed for compliance and complex systems.
- Codebase complexity reduces AI productivity gains; opinionated frameworks like Ruby on Rails improve AI accuracy in greenfield projects.
- Future trends suggest increased reliance on AI code reviews to match the pace of code generation, improving PR cycle times significantly.
