I tried listening in and there were a lot of really intuitively strung-together tangents, each of which could be considered its own separate knowledge domain. I guess I'd say it was very ADHD-friendly, practically an ADHD machine, in that way. I had to give up on the video for now because I kept losing the thread while wondering about this tangent or that one. Will look for a summary later. (I do like that the corresponding gift of Musk's, the connective, big-picture thinking, is being made to work for its money though)
