Sounds like an argument for making CEO a part time position. If Musk can be CEO of 3 companies at once and still tweet 24/7, the role of CEO seems pretty light.
Like, if my day-to-day duties are so light that I can take a similar full time job at 2 other companies, and everyone gets on fine while I’m gone doing those other jobs, maybe that’s an indication I’m not really doing anything important in the first place.
