Do you seriously think Elon works 100 hours a week? What evidence do you have to support this?

Most people do find fulfillment out of work, many even enjoy it, myself included. That doesn't mean that we shouldn't fight to be compensated for what we put in, and doesn't mean we shouldn't practice solidarity with coworkers, many of whom don't have the time to work as much as we do (for example a working mother).
