Understand what makes this debt different
The standard narrative frames this as AI writing bad code. That’s not quite right. The more precise problem is cognitive debt: the loss of understanding of how and why software was built the way it was.
When a human writes code, something else happens alongside the typing. They simulate edge cases, reason through dependencies, and make judgment calls grounded in organizational context, including the business requirements behind a feature, the best practices the team has established, and the reasoning behind past architectural choices. That cognitive loop is how institutional knowledge gets built. When AI writes the code, you can get output that is syntactically correct, passes CI, ships cleanly, and leaves no one holding the mental model. The code works until something changes or breaks, and then the team is excavating a black box.
This is distinct from traditional technical debt, which is messy code. Cognitive debt is invisible code that functions but that nobody truly owns. And it compounds faster, because the same velocity that makes AI generation attractive is what prevents anyone from stopping to build the understanding that maintainability requires.
