Summary
METR's 2025 experiment with 16 experienced developers on 246 real tasks found that AI tools made them 19% slower, despite developers believing they were 20% faster. The SPACE framework from Microsoft Research and GitHub warns that developer productivity is multidimensional, and single metrics like lines of code, PRs merged, or suggestion acceptance rates are easily gamed by AI agents. Goodhart's law applies aggressively here—when a measure becomes a target, AI inflates it without improving actual output.
