Musk also denied he’s ever compared himself to a Samurai. So there’s that.

But Musk, who was responding specifically to this summary in the Washington Post, hasn’t disputed any other quotes from the book that are making the rounds today—none of which are quite as distressing as the supposed birth-over-meeting dustup, but suggest nonetheless that he is a maniacally demanding boss and utter workaholic. They include such gems as:

That’s my lesson for taking a vacation: vacation will kill you.”

Musk’s disdain for vacation time is well documented. “The idea of lying on the beach…sounds like the worst,” he has also been quoted as saying.

“I would tell those people they will get to see their families a lot when we go bankrupt.”

This comment was reportedly made in response to an employee complaint about long work hours.

“We’ve grown [expletive] soft.”

Musk apparently made this comment when not enough people turned up for work on a Saturday.

Perhaps it’s not that surprising that work-life balance is not a huge priority for someone trying to colonize Mars or change the way the world consumes energy. Unlike some other executives running companies in Silicon Valley, at least he’s honest about it.
