“More than 70% of pull requests at Uber are now written by agents.”
A pull request is not a unit of value, it is a unit of paperwork. Uber counts 250 automated migrations rewriting 9 million lines, which is exactly the mechanical find-and-replace work that inflates the PR number without proving anything about hard problems. Nobody publishes the revert rate, the incident rate, or what the 100 million daily model requests cost. “Code shipped per engineer has doubled” is a metric you pick when the ones that matter look worse.
