AI Is Creating a New Kind of Tech Debt — And Nobody Is Talking About It

Your AI agent shipped 47 features last quarter. Congratulations. Now tell me how many of them you actually understand. This is the part nobody puts in the press release. Teams everywhere are celebrating velocity numbers while quietly accumulating a debt that doesn't show up in any accounting system. It's not the old kind of tech debt — the "we'll refactor this later" kind that at least someone wrote down somewhere. It's something newer and harder to see. AI-generated code looks clean.
