But imo, content issues are fixable, it just takes way more time. Good online courses with good content and good exercises will become more common.
What will be harder is to simulate the social effects and mutual communication, that will be fixable too in time. That will however require also changes outside of school - people will have to learn how to find friendships and communities without institutional support of school.
Online courses have several advantages:
1) The lecturer can prepare a video, refine it, and have others review it before it makes it to the students. Errors can be corrected and annotations can be added.
2) Quizzes, tests, and projects can be effectively randomized to dissuade cheating (see coursera courses).
3) Other resources can be linked directly in the material.
4) Written information for the courses can be intermixed with video lectures.
5) Asking questions is easy and doesn't disrupt the rest of the class.
6) You learn at your own rate.
Most of my more challenging courses at university (math and engineering) did not have any discussion anyway, and the instruction was extremely poor. If Khan Academy or Coursera had existed at the time, I'd have done much better using those courses than learning from my actual professors.
Make sure to blame the university, not the professors. We're trying our best with almost no help.
The online version had:
1) lots of busywork for the sake of busywork (to make up for attendance?)
2) much poorer instruction. Like everything felt like it was written by someone (really a group of people) who didn’t understand the subject very well, which was strange because the in person class was taught by a DR. with a very good understand and a strong passion for it.
3) no organic classroom interaction, people making friends that way have to be an extreme exception. It almost felt like this was actively discouraged to avoid a liability? I’m not sure, but that’s a huge part of the value of going to class that’s totally gone now.
4) and because of that no real discussion (you had discussion boards but those are more like public essays than real conversations.)
The only reason it’s better than just reading a book and doing exercises is that all the administrators recognize you’ve done it, the whole situation is just really dumb.
