This just came up on my YouTube feed two years later. Wow, what an extraordinarily prescient discussion.
That gentleman must have created for himself one of the most fantastic job ever : to meet brilliant minds and to LEARN every time . Bravo !
The beauty of this channel. Finally, someone who can talk to so many people about so many advanced things.
I really liked this conversation. This guy's awesome. As a kind of related aside, the auto-generated CC are amazing for someone with such a strong French accent.
Lex, thanks for putting together high quality interviews with rock stars of the nerd-verse. I appreciate these videos a lot 😬, keep it up 👍
