Are you trying to imply that you have some teaching experience of your own? You're doing an incredibly bad job of establishing your credibility in this thread. Try being less combative and providing some substantive explanations for why you're so strongly convinced that there's no room for improvement over the status quo.

In particular, I'm curious how you come to the conclusion that high-quality video content cannot work better for "the vast majority of students" than sitting in a lecture hall. Do you have any theories about what kind of student good video content can work well for?
