The AI Productivity Paradox in Engineering
summary
Data shows AI coding assistants raise deployment velocity ~20% while incidents per PR climb ~23.5%, and fewer than expected organizations have formal AI governance, per Cortex’s "Engineering in the Age of AI: 2026 Benchmark Report" and Sonar’s survey. Modern LLMs (tracked on a Sonar leaderboard) produce better code but teams throw harder problems at them. Testing and SLOs act as the crucial safety harness, and teams must reallocate AI productivity gains to operational maturity (CI, canary deploys, observability) to stop speed from degrading reliability.
