Code Churn Doubled While We Were Celebrating AI Speed Gains
Recent analysis reveals that code churn has doubled, rising from 3.3% to 7.1%, while AI now generates about 41% of all code in professional workflows. Despite increased code production, the stability of deliveries has decreased by 7.2% year over year, indicating a troubling trend. Experts suggest that the focus should shift from merely increasing code output to improving the review process and understanding the risks associated with code changes.
