This course is a bunch of presentation slides. The idea that you can learn anything from slides is rather silly. Learning from slides is almost as bad as learning from random youtube videos.
Slides can be an extremely good medium for learning. Because brevity is required by the format, slides can require a lot more thoughtful attention to emphasize and carefully explain key points than the long-form text format. I think the course looks really nice!
In fact when I read a book I do little cards, like slides, with the most important information condensed.
I find a good method.
All channels with reputation at some point were random (except the ones from universities maybe)
YouTube videos are fine, at least they have narration. With slides you're kinda left to infer your own story and lessons.
