Measuring the Impact of Early-2025 AI on Experienced Open-Source Developer Productivity

Joel Becker, Nate Rush, Elizabeth Barnes, David Rein · 2025

A controlled trial of how early-2025 AI tools affected experienced open-source developers' productivity. The companion cites its finding that the tools slowed expert programmers by 19%, as a modest counterweight to reports of AI-led research. It appears in the discussion of superparental descent (P7), which the companion says is not yet demonstrated.
