Quoting Florian Herrengt
AI-assisted development is creating codebases no human engineer understands
“Neither of you has any idea whether any of it is true but Claude seems very confident.”
Florian Herrengt warns that heavy AI coding reliance is producing a 'cognitive debt' crisis where engineers can no longer explain their own systems and recurring bugs become unfixable because no human understands the codebase. The piece frames this as AI hollowing out the 'middle class' of software engineering — the layer of developers who held deep contextual knowledge. This is a meaningful signal as the industry debate shifts from AI productivity gains to long-term comprehension and maintainability risks.
