I wish that I could share your optimism about online education, but I don’t. I have seen liberal arts online courses where you HAVE TO give back the leftist answer that the professor is spouting or you will be given an “F.” When I checked the “ratemyprofessor.com” comments on these professors, other students said the same thing: give a leftist answer or get an “F”.
Sure, there’s a process involved and as we’re at the early stages now, things like this will happen, at least until we get to the teacher-less classes. But still, look at the difference between that experience and being in the class, live, where not only do you have to give back the right answer, but you can’t even mutter any dissent under your breath.
For example, in the experience you just cited, yeah, you had to give back the answer the leftist instructor expected, but minutes later you got to vent your disgust over this with like minded students. And as an act of defiance you could still take the course wearing a MAGA hat (and maybe nothing else) while you take the class, and the teacher would never know. So those are brainwashing cures you can’t really get in the traditional university experience.
