I use co-pilot for enhanced tab-completion of small blocks of code. Basically, it saves me some typing now and again. I find it guesses incorrectly a third of the time but I often still tab complete then go back and fix it. Is this "using ai to write 90% of my code"?
When I have used copilot conversation mode and requested a refactoring or provided what I felt was a clear description of my task, the result shave always been a failure that required more time to resolve than if I had just done the work myself.
These are issues I could see and determine where wrong. I weep for the future where these changes get pushed live because no-one knows what the vibe-coders did any more.
