This is a podcast as well as a YouTube channel so I think it qualifies to be here.
Lex Fridman has some fascinating guests on his podcast. I find him a great interviewer as he's incredibly intelligent himself so understands alot of the concepts more than a presenter on TV would.
Not sure what I think of Elon Musk as a person but I found this discussion absolutely fascinating, he's obviously a genius, probably on a par with Da Vinci when you consider the breadth of disciplines he's involved with.
Found his explanation of money as a database particularly interesting on this one. We really are so lucky nowadays that we can listen to long form conversations with the most interesting people of the time, historians jobs will be alot easier in the future.
