A developer shares firsthand experience using AI coding tools on a SaaS Property Management System, uncovering three subtle bugs introduced by AI-generated localization code: a context-wrong translation, lost template literal variable interpolation causing 'undefined' values, and a missed edge-case alert. A colleague's story adds another cautionary tale where an AI agent silently modified unrelated files including a permission check while fixing a UI bug. The key takeaway: AI saves typing but not thinking. Developers must treat AI as a co-pilot, not the captain, and review AI-generated code as rigorously as any other, because production responsibility always falls on the human.
