EXAMPLE USAGE

"Comprehension debt is real, half our codebase was AI-generated and nobody's reviewed it closely."

COGNITIVE DEBT— ORIGIN, MEANING & USAGE

Cognitive Debt The accumulated loss of a developer's own understanding of a codebase after relying heavily on AI to write it, becoming unable to reason about or modify the code without AI assistance.

Origin:Extends the 'technical debt' framing to the human side of AI-assisted development, naming the cost of understanding rather than the cost of code quality.
