Thinking back, I have had some woderfull professors that had expertise beyond just published work and knew how to convey it.
Then I have had many bland curriculum reciters matching a semi decent youtube lecture, and some bad communicators where you were better of just reading the book they tried to teach.
There was also a few that couldn't really teach, but whose class was more like a standup comedy performance.
I'd say with the exception of the first and last group, ChatGPT would probably be a good if not better replacement for day to day teaching and mentoring.
