AI Coding Tools: A 19% Productivity Drop for Experienced Developers

A rigorous study of experienced developers using AI coding tools reveals a surprising 19% decrease in productivity, contradicting developers' self-reported expectation of a 20% increase. The study found that AI-generated code often failed to meet the high standards of mature, large-scale projects, leading to significant time spent reviewing and correcting the AI's output. This highlights the limitations of current AI coding tools, suggesting that their effectiveness is heavily dependent on project type, developer experience, and the maturity of the tools themselves.
