I think people who hype on and on about his personal life are just grasping at straws to mask their own insecurities.
As someone who grew up not spending that cliched ooey gooey version of "family time" that we always see on television and someone who has been married once, I'm fairly sure it's a lot more complicated than "oh always working, and doesn't care about his family? --insert underhanded "I'm better than you statement here"--. My parents worked hard to take care of me and my sisters. Did I see them all the time? nope. Was I bothered? nope. At the end of the day whenever I needed them they would drop everything and show up. We never had dinner at the table, as a matter of fact I pretty much up and moved out when i was 17. But we're a very close family. As for my marriage, despite how hard we tried to maintain it, one can't control feelings, and eventually we realized that even though we were comfortable with each other, we couldn't get those feelings back.
Now, I don't know Elon Musk, and quite frankly I think there's a bit too much hero worship surrounding him - don't get me wrong, he does some crazy stuff, but he's not as much a sage entrepreneur as we make him out to be. Having said that, the reality is that life is a lot more complicated than what it looks like on Little House on the Prairie. A "close family" doesn't have to sit around the table and chat, a close family doesn't even have to have members who live in the same country - I'm a case in point. So people talking about how he's some bad father as if they live with him or know him personally should go focus on their own personal lives. And to John Battelle's, quite frankly rude statement at SXSW, well he works at a media company that hosts conferences, not running and re-imagining two pillars of heavy industry.
