But it's important to remember that Elon and Jobs were unicorns. It should be an immediate redflag if people compare others to them. I also think it's unfair to compare Square/Twitter with SpaceX/Tesla or with Apple/Pixar.

Also the above commenter's point, talking to people 16 hours a day does not mean you're working. An engineer's work is quantifiable, so they can be held accountable when they claim they work 16 hours a day. Not so for a manager. Their effect (good or bad) is far more difficult to quantify.
