Elon Musk is in top-20 in the world in Diablo. "I'm in the top 20 in the world in Diablo IV. I'm listed with my actual name on the list. There's only two Americans in the top 20, and I'm one of them." "If I play a video game on extreme difficulty, I have to concentrate fully on the game and it has a calming effect. I think anything that forces you to concentrate fully has a restoring effect." "It cleans the mind." "Video games require manual dexterity. If someone is good at video games their surgical skills might be good. If someone is a top ranked video game player and a surgeon, that's the guy I want."
