Gates has amassed an average of $1.66 billion annually over his lifetime. I would be more than willing to act a complete fool in front of a stadium full of people for a small portion of that.
Steve Ballmer was just cringey nuts. It's like he was trying his best to be weird. Gates is the typical nerd who cannot dance but is really smart. Why try to be "cool"?
Now Steve Jobs was cool. He didn't have to dance and do silly sheet, it was awesome just to listen to him. I miss his presence Apple has become so boring and no one else other than Elon is close.
