You can't be serious...
Musk's #1 trait, for better or worse, is promotion. Or do you really think he's the guy doing the engineering on all this stuff?
He has an undergraduate degree in Physics. There is no focus on "energy storage".
In what sense? Because the companies he runs do great engineering? Was Steve Ballmer a great engineer because Microsoft built great things? What about Steve Jobs?
Elon Musk is great at a crucial skill for CEOs: selling a vision.
You mean, financing a vision? I don't see many other billionaires doing that (Gates & Buffet excluded).
Do you say that because his wealth is tied up in the companies? Yeah, and Zuckerberg "finances" Facebook, and Larry Ellison "finances" Oracle, and Larry and Sergy "finance" Google...
Tesla has sold vast amounts of equity and debt. That's how the company is financed.
I used to be a huge fan - this IS the Tesla and SpaceX guy, but man, follow him on Twitter long enough and you just want him to fuck off.
EDIT: I will further add that I really don't think you can just take the bad without looking at the good. It is factual to say that he has helped many people learn to take personal responsibility and improve their lives. I don't think you can take that for granted. I don't necessarily trust everything he says but I'm not sure where the Trump comparison comes from. Whether you are a Trump fan or not, I don't think they are really comparable...
Elon Musk has public events that demonstrate his thin-skin (unlike the poster you refer to). Like when he wrote journalists angrily because they didn't mention him as a co-founder of Tesla, even though, you know, he didn't co-found it?
