He's built a very cool rocket company, but on HN people take the CTO title at face value and assume he's a genius rocket scientist. He's built a cool car company, and is right to focus on battery technology and solar being better than biofuels etc etc. I admire him a lot, but i think a lot of people project their ideals onto him as a sort of symbol of the primacy of the Valley Way, which they're staking their twenties and thirties on. Whilst taxonomy doesn't really achieve much, I sort of think of him as more Henry Ford than some sort of Tony Stark/Einstein hybrid that is often seen here.
Like I said, there's a lot to admire, but he's just a guy still. Petty, tantrums, lots of SpaceXers i know (current and former) talk about how really you have to go to Gwynne Shotwell for some sober leadership and patience when he jumps the shark a bit, and she can speak truth unto power and figure out a way forward. She never gets mentioned from from what one hears in this industry (I'm in it to) she deserves a lot of credit.
