Good teachers aren't lecturing. They're facilitating. They're bringing in discussions, showing examples, and helping students learn. The reason the online classes work is because students figured out that instructor/content focused courses don't require students to actually attend.

Look at "flipped classrooms" where students read and watch lectures at home and then come to class prepared to discuss and perform.

I don't think I'm an exceptioanl teacher but I think I'm quite good, and students who've taken online classes prefer having some face-to-face time with me and other students because I don't lecture and read powerpoints for 60 minutes.

Any instructor/professor that lectures, recites, and PowerPoints is absolutely in danger of being replaced by an online course because they add little value.
