How does he even have time to play games

Because he is a CEO.

CEOs don’t actually do anything, they are just a face. They collect all the money and then fuck off to do whatever they want, which for musk is TV interviews, trump rallies, obsess over Twitter and apparently play video games.

I mean ideally CEOs make informed decisions and have at least a pretty good grasp about what the company does and what could be done to make it better (after listening to people under him). CEOs like Musk are lazy and skip the actual work and make uninformed decisions that hurt the company.
