I did an impromptu training session with Elon Musk for a few hours yesterday. I'm extremely impressed with his strength, power, and skill, on the feet and on the ground. It was epic. It's really inspiring to see Elon and Mark doing martial arts, but I think the world is served far better if they train martial arts but not fight in the cage. That said, as Elon says, the most entertaining outcome is the most likely... I'm there for them, no matter what.
