Before starting tasks, developers forecast that allowing AI will reduce completion
time by 24%. After completing the study, developers estimate that allowing AI
reduced completion time by 20%. Surprisingly, we find that allowing AI actually
increases completion time by 19%—AI tooling slowed developers down. This
slowdown also contradicts predictions from experts in economics (39% shorter)
and ML (38% shorter).
