Look, Musk /is/ out to change the world. His employees might not be, at least to the degree and level as he is. And, if they are, they'll likely not be remembered along with Musk. There is often only one, maybe two names attached to great achievements. If I'm an employee at a company like that (and I have been, and I have killed myself with long hours making someone else rich when I was young and dumb, before I realized what it was all about), I would do my job very, very well and make sure I have the balance in life /I/ want.
You don't want me to see the birth of my child? Sorry, fuck off. It's my time, my life, my family, my kid. And we aren't talking about a tee-ball game. This is the BIRTH. We aren't talking about kindergarten parent-teacher conferences. This is the birth, where you support your wife and see your child for the first time.
And, sadly, Musk probably doesn't realize because he is so wrapped up in his own world, but having a child IS changing the world for a few folks. But, ya know, sociopaths don't care about other people, just themselves.
I'm continually saddened that we put people on pedestals who so clearly aren't deserving of it. Musk is just another example of someone who /really/ is out for theirs and want to get it any way possible. I think we all thought, or maybe hoped, he was different. I don't know that he is.
