I’d be very surprised if Elon consistently works more than 60 hours a week, and pretty surprised if it was more than 50. It’d be a waste of his position and talent if he did. He has the capital and influence to have others do almost all other tasks, his main focus is likely to be on longer term strategy and thinking. He’s also a dad of 5 or so kids. His health is far more valuable than working 2 typical work weeks every week.
He plays up the uberworker shtick for the same reason Warren Buffet in his 80s tells everyone he has a coke and Dairy Queen everyday: because it’s part of his brand and very conducive to moving forward his pursuits. Warren buffet definitely doesn’t have coke and Dairy Queen everyday either.
Elon’s days of working to the bone everyday are likely long behind him, by decades.
