So I went through this lastmost video and made some notes, mostly on the first half of it, where the presenter was still talking about physics, since I'm insufficiently informed to comment on much of the rest... However, since you mention none of it in your post, nor inquire for anyone's opinion on any of it, I'm not sure how much relevance to the subject at hand any of my comments would have. Was this posted up for discussion, or is this strictly for our enjoyment and no critical review? Of course, even outside of your intent in posting it, if someone else wishes to chat about the contents, I could, too, present what I have.
Better to leave questions unanswered than answers unquestioned
