But you forget about labs and technical classes. There are many courses that cannot be done by watching a video.
I made this point (about labs and such) myself yesterday in another thread. Laboratory science, professional schools (e.g., conservatory and nursing), internships, and other courses of study involving skills and development of teamwork and professional judgment are going to be difficult to move to digital. I’ll give an example. I routinely remark in my MBA classes that few of my students work with their hands. One time, I got a student to respond. He said, yes, he works with his hands. I asked what did he do. He said he was a heart surgeon. So, whether you are an auto mechanic, a mason, a plumber, or a heart surgeon, it seems to me, you can’t just learn it out of a book. I hope that my school gets back to campus after the time out we have called.
