He's not unlike Steve Jobs. They both possessed enough knowledge and technical acumen to understand what they're being told about disparate subjects, but they may not have the in-depth knowledge that a Jim Keller would. And despite my enormous respect for Keller, he's not an Elon Musk or a Steve Jobs. Jim's a craftsman at heart, and that comes through in interviews with him. Musk and Jobs are true visionaries.
This is not genius-level but is the blending of two skills, a charismatic Administator, who can temporarily suspend disbelief, and a Fundraiser. Each of those takes a ton of work. I'm not minimizing Musk's dilligence in any way, but there are lots of people who can do those activities at high levels. The difference is that most people can't survive their tweeting SEC violations while stoned.
