AI-assisted coding is transforming how software gets built. But the data tells a sobering story: - 1.7x more bugs in AI-generated code compared to human-written code (CodeRabbit, 2025) - 40% of AI-generated code contains security vulnerabilities - 2026 is "the year of technical debt from vibe coding" (Forrester) The root cause is not the AI. It is the absence of engineering discipline between sess
