- AI adoption increased 65%, but median PR throughput rose only 7.76% (mean 13.1%).
- Coding constitutes only ~16% of engineer time, so speeding it up has limited overall impact.
- New bottlenecks like code review and integration absorb time saved, often resulting in net-zero productivity gain.
- Skill and tooling gaps create a J-curve; advanced users outperform after practice and education.
- To unlock more, focus AI on non-coding bottlenecks, assess codebase readiness, and track utilization, impact, and cost together.
