I found this very interesting and valuable (if imperfect). The point about lectures is where I disagreed most, and I don’t see it discussed in this thread. The two points that people read much faster than a lecture pace, and people don’t learn well just from reading at full speed, should tell you something. Lectures are designed for active listening and frequently contain questions, pauses for discussion, and desirable difficulty (e.g. I claim something and give you a few seconds to figure out why it’s true). This is also why prerecorded or YouTube lectures are a game changer. It’s a different medium more like reading notes than like participating in a class.
