Vibe Coding Costs You 20% Productivity - Why AI Coding Agents Create Technical Debt

Learn why AI coding agents may be reducing your productivity by 20% through this 18-minute conference talk that exposes the hidden costs of "vibe coding" and automated development practices. Discover how blind reliance on AI tools creates technical debt and reduces actual coding efficiency, despite the perception of increased speed. Explore three practical solutions to maintain control over AI-assisted development: interactive planning to prevent agent lock-out, escaping the "Async Valley of Death," and implementing code maps to understand generated code before implementation. Understand the mathematics behind token costs and why investing $12 per day in AI tools can be more cost-effective than accepting reduced productivity. Examine real-world examples including production database deletion incidents and the "2 Devs = 50 Devs of Debt" phenomenon that demonstrates how AI automation can exponentially increase technical debt when used incorrectly.
