1) Doesn't want to speculate on Hyperloop before he's sure it can exist
2) Freely admits he was too shy to talk to anyone in the Netscape lobby when he went there fresh out of college looking for a job
3) Doesn't read a lot of general business books. Instead reads auto-/biographies of scientists and entrepreneurs.
Plus, he likes Burning Man (I love it but it's not for everyone) and casually mentions he had the idea for a "super-sonic vertical takeoff and landing plane" there. In comparison, I just got back from BM and my only work-related idea was that I should really put some more effort into my work.
So far I haven't heard any stories about him being an ass either, which is very reassuring for those of us who don't want to be like Steve Jobs. Even in this interview he seems reluctant to reveal too much information about people he didn't like working with.
I just wish people like him were more attracted to politics. I wonder if it's because nobody would elect people like Elon Musk or because those people avoid politics.
