Technical-Debt

Your AI-Generated Codebase Is a Liability

If a quarter of Y Combinator startups have codebases that are over 95% AI-generated, we should probably talk about what that means when those companies get acquired, audited, or sued.

AI-generated code looks clean. It follows conventions. It passes linting. It often has reasonable test coverage. By most surface-level metrics, it appears to be high-quality software.

But underneath the polished exterior, AI-generated codebases carry risks that traditional codebases don’t. Security vulnerabilities that look correct. Intellectual property questions that don’t have clear answers. Structural problems that emerge only under stress. Dependency chains that nobody consciously chose.

Comprehension Debt: When Your Team Can't Explain Its Own Code

Technical debt is a concept every engineering leader understands. You take a shortcut now, knowing you’ll need to come back and fix it later. The debt is visible: you can point to the code, explain what’s wrong with it, and estimate the cost of fixing it.

AI-generated code is introducing something different—and arguably worse. Researchers have started calling it “comprehension debt”: shipping code that works but that nobody on your team can fully explain.
