Here is what happened to code review in 2026. AI writes the code. AI reviews the code. A human clicks approve. The PR merges. Everyone moves on. Nobody in that chain actually read the diff.
This is not a prediction. This is Tuesday.
46% of all code on GitHub is now AI-generated. In Java repositories, that number is 61%. Teams with high AI adoption merge 98% more pull requests than they did before. And the time spent reviewing those pull requests increased by 91%. Not because people are reviewing more carefully. Because there is more to review and the reviews take longer to skim.
The volume of AI-generated code is projected to outstrip human review capacity by 40% this year. The code is arriving faster than humans can read it. So they stopped reading it.
