I've recently taken more than one online college course where the professor is absentee. No lecture, scant materials or materials with conspicuous errors, a small pdf clip from a free book, or links to a couple short YouTube videos by other people. Classes that the university is making $40,000+ off per semester. No wonder students are looking for other sources for their work.
Pretty soon classes will just be professor's and student's AI talking to each other in GibberLink.
