The ChatGPT of 4 years from now will get its answers from the copilot-enabled editors of people who know how to do the thing. If we're lucky it'll also be paying those people royalties, but I'm not holding my breath.
Tracing the fix-it sessions backwards in time to the broke-it sessions (such that the AI can learn from its mistakes) might be tricky unless we somehow manage to connect copiloting sessions through git history. Imagine a big database of changes where the AI is waiting to see whether the code persists, or if somebody comes along and fixes it.
so is github...
