I mass deleted 3 months of AI generated code last week. Here is what I learned.

Three months of building a side project almost entirely with AI assistance. ChatGPT, Claude, Copilot, the works. Shipped fast, felt productive, everything seemed fine. Then I needed to add a feature that touched most of the codebase. And I realized I could not do it. Not because it was hard, but because I did not actually understand how my own project worked. The AI had generated clean looking code with consistent patterns, but the patterns were not mine. I could not trace the logic from memory. I could not explain to someone else why a function was structured the way it was.
