I’ve been working with copilot a few months and the biggest surprise is how it has led to much better commented code. I used to comment tricky code to explain it. Now I comment trivial code instead of writing it. Often two lines of comment will get me 10 lines of copiloted code, faster than I could have typed it and with good comments to boot.
Co-pilot has been very useful the times I've used it. It's not perfect, but does cover a lot of boiler plate. It also makes it much easier to jump between languages.
