Generative AI Reshapes Developer Time Allocation
9.2
Harvard Business School working paper surveying 187,000 open-source developers finds that free access to GitHub Copilot shifted work composition, increasing coding time by 12.4% and reducing project-management time by 24.9%. The study also reports 22% more exposure to new languages among users but notes sharp declines in peer collaboration and rising code-review burdens cited by other reports, implying workflow and hiring implications.
Key Points
- 1Finds Copilot increases hands-on coding by 12.4% and reduces project-management time by 24.9%.
- 2Shows junior and less-experienced maintainers gain most, with 22% more exposure to new languages.
- 3Warns collaboration and peer review fall sharply, raising code-quality and organizational cohesion concerns.
Scoring Rationale
High relevance and robust HBS dataset, limited to open-source maintainers so findings may not generalize broadly.
