Lex Fridman, man, he's a fascinating guy. Not your typical AI scientist, that's for sure. He's this deep thinking, guitar playing gentleman with a badass Jiu-Jitsu black belt. He's got a podcast too, where he has conversations with some of the most interesting people on the planet.

I had him on the show and one of the things we talked about was his talk with Elon Musk. And boy, was he impressed! He was particularly stoked about how Elon thinks - the first principles, the physics level of the problems Elon is trying to solve, whether it's SpaceX or Neuralink.

And then there's a different side to Lex - the song he wrote, inspired by his veteran grandfather. It's a deeply emotional piece, and you can feel the weight of history in his words.

So, Lex is not just a scientist, he's a musician, a martial artist, a philosopher in some ways. He's one of those rare folks who can talk about complex topics like artificial intelligence and self-driving cars and then switch gears to talk about life, music, and everything in between. It's always a pleasure to talk to him.
