Tesla and SpaceX workers should put in 80 to 100 hours a week to "change the world", Elon Musk has said.
The technology entrepreneur admitted that there were "way easier places to work" than his companies, adding: "Nobody ever changed the world on 40 hours a week."
Asked how many hours a week were necessary, Mr Musk said: "Varies per person, but about 80 sustained, peaking above 100 at times. Pain level increases exponentially above 80."
It could be worse. You could be doing 80 hours a week of unpaid work, coding one of the many open source projects which Musk and companies gleefully exploit for free profit [electrek.co].
