AI coding tools make developers feel faster but are 19% slower, study finds · 3 sources tracked

By PulseAugur Editorial · [3 sources] ·

A recent study indicates that while developers using AI coding tools *feel* approximately 20% faster, their actual measured productivity has decreased by about 19%. This phenomenon, termed 'the gauge broke,' suggests that AI tools, while speeding up typing, introduce new bottlenecks in code review and verification, particularly for experienced developers working on existing codebases. Telemetry data from Faros AI and research from DORA corroborate these findings, showing increased pull request volume and review times, alongside a drop in delivery stability, with no net increase in overall delivery speed. AI

IMPACT AI coding tools may be creating a false sense of speed, potentially leading to misinformed adoption decisions and actual productivity losses for experienced developers.

RANK_REASON The cluster discusses a study and its implications on developer productivity with AI tools, which falls under commentary on AI's impact.
