I see people on Zulip using Copilot to write Lean proofs, and they have some success, but the quality is really bad right now, creating long, unmaintainable proofs. New users get stuck, thinking they're 90% of the way to the end, but really the whole thing probably should be scrapped and they should start over.

It's a bit frustrating because, before Copilot, new users would come with proofs and you could spend some time helping them write better proofs and they'd learn things and gain skills, but now it's not clear that this is time well spent on my part. Copilot is not going to learn from my feedback.
