"<a href=""https://www.youtube.com/watch?v=50r-5ULcWgY&amp;t=1h02m45s"">1:02:45</a>", mention of Crypto, albeit in the context of making money without endevour. I very much admire Sir Martin Rees but that was a sweeping comment about Crypto. He's probably not aware of projects such as Hedera Hashgraph (and others) which are "Crypto" but in essence software, that will do a lot of good. Apologies an esoteric comment, he can't know everything! Lex, I think your interviews are on another level, brilliant.
