When AI Coding Outpaces Quality Control

AI-assisted coding tools have dramatically accelerated development velocity, but this speed has exposed a critical bottleneck shift—from code writing to code review. Metrics reveal alarming quality declines: code churn spiked to 7.9%, refactoring plummeted to under 10%, and code duplication increased eightfold, demonstrating that speed without structural safeguards accumulates technical debt that threatens long-term system stability.
