GitHub data (commits, PRs, lines changed) was analyzed using a Difference-in-Differences approach against 90-day baselines. Key findings: Cursor showed almost no measurable productivity lift despite users reporting feeling more productive; Claude Code showed significant output gains, but only after developers built trust and stopped micromanaging it. 47% of exit survey respondents said they accomplished tasks they wouldn't have attempted before. The experiment is now driving a company-wide rollout, but the author warns of an emerging 'AI Curse'—individual productivity exploding while organizational coordination, CI/CD pipelines, and review processes become the new bottleneck. ## Full article daily.dev links to this article rather than hosting it.
