I think this significantly misses the point of higher education. By far the most valuable parts are 1) peer interaction, and 2) lecturer-audience interaction.

I think this significantly misses the point of higher education. By far the most valuable parts are 1) peer interaction, and 2) lecturer-audience interaction. I learned way more from discussing the topic with my classmate during breaks than I ever did from the course material itself. Learning a fact is easy, deeply understanding it is not - and discussing it with your peers is the best way to discover each others' flaws in understanding. In addition to this, people asking questions is a crucial part of the lecture. Sometimes a question is because someone was asleep during the previous lecture, but most of the times it was because a concept was not explained clearly. And in a few rare but valuable cases someone asked a question, and the lecturer's eyes lit up as someone had rediscovered an open research problem - or made a critical link between two seemingly unrelated topics. Textbooks and videos can teach you a lot, but they do not allow for interaction. If you wish to simply get a basic understanding of a well-known topic, that might be enough. But if you want to truly master it and perhaps even contribute to advancing it yourself, it simply isn't enough.
