Don't Miss Long Elon Musk Interview

Heads and shoulders above any Musk interview I've ever heard. He delves into some engineering problems, explained in beautifully penetrable language. This will transform your view of SpaceX (other stuff, too; I haven't heard the whole thing yet; I paused to rave about it). Really, don't miss.

Host Lex Fridman initially struck me as a little "off", but he's actually a heavyweight himself (he's the heavy Deep Learning/AI guy at MIT), which is why Musk respects him, which is why he gave him so much of his time (2.5 hours, which is more than I think Musk sleeps in a night).
