I let Copilot, Cursor, and ChatGPT write 80% of my code for 18 months. Then I turned them off for a month. What happened next shocked me — and it might change how you think about AI in your own work.
Let me start with a confession.
Three months ago, I was staring at a pull request diff at 11:47 PM, unable to explain my own code.
The feature worked. The tests passed. The review got approved in 12 minutes. But when my teammate asked, "Why did you use a WeakMap here instead of a plain object?" — I froze.
Because I didn't write it. Cursor did. I had tab-completed that WeakMap into existence three days earlier, and I couldn't remember why it was there. I couldn't even remember reading the suggestion.
