>Listening to a professor speaking to himself from a distance of 10 meters

But is that the default, common experience? I'm asking seriously: I finished my bachelor's 30 years ago and my master's 15 years ago and that has never been my experience.

Our professors were actual people we talked and interacted with, even the boring ones. And they made an effort to teach. Now, I didn't go to a huge "research" university, where I hear it's common to get profs who have no interest in teaching, but what you describe isn't remotely like what I encountered.

Yeah, the best classes I've attended began with you reading material (textbook or papers) before lecture, then revisiting that content during lecture. Ideally the prof devises a lecture agenda where discussion revolves around subtleties in the material, both clarifying Q&A and implications and exceptions and to the material. Appreciating the context and relevance of your research-based material adds a lot to appreciating how it changed the status quo.
