🤖AI Summary

A controlled study of 151 professional developers found that AI coding assistants like GitHub Copilot provide significant productivity gains (30.7% faster completion) but don't impact code maintainability when other developers later modify the code. The research suggests AI-assisted code is neither easier nor harder for subsequent developers to work with.

Key Takeaways
  • AI coding assistants reduced development time by 30.7% median, with habitual users seeing 55.9% speedup
  • Code created with AI assistance showed no significant differences in maintainability when evolved by other developers
  • No systematic advantages or disadvantages were detected in code quality or completion time for subsequent evolution
  • Study involved 151 participants with 95% being professional developers in a two-phase controlled experiment
  • Future research should examine risks like code bloat and cognitive debt from increased AI reliance
