AI Coding Tools: Productivity Killers?

A randomized controlled trial involving 16 experienced developers revealed that AI coding tools, contrary to expectations, decreased software development speed by 19%. The study attributed this slowdown to factors such as over-optimism about AI's usefulness, high developer familiarity with the codebase, the complexity of large repositories, and low AI reliability. While AI tools can expedite testing and automate tasks, the need for manual code validation and the lack of learning capabilities negate overall time savings. The researchers emphasize that these findings don't dismiss the future potential of AI tools but highlight the current limitations.
