I haven't worked for Musk, we've never met, but I see Steve Jobs in him from all I read. And I have met, competed with, and partnered with Jeff Bezos, and see parallels with both Musk and Jobs. Anyone who has worked for Jeff knows about his legendary "nutters" when he loses it in meetings and goes nuts.
There was a meeting between Steve and Quantum when Steve realized he needed a hard drive for the Mac that I will write up in a day or two here on Cake. I have always wondered, did that meeting show his genius or ruthlessness or his unique combination of the two? I finally decided it was both.
