Study Finds AI Tools Slow Veteran Open-Source Developers by 19%
A randomized controlled trial with 16 seasoned open-source contributors tackling 246 real issues showed they took 19% longer when using AI tools like Cursor Pro with Claude 3.5/3.7. Developers had anticipated a 24% speedup and still reported a perceived boost after the slowdown. The result challenges the belief that generative AI automatically accelerates software development.
