Musk has admitted on several occasions that running more than one company isn't easy. He splits time between his companies depending on the "crisis of the moment," the 52-year-old said in 2021.
One X user pointed out in January 2023 that Musk had testified in a lawsuit in the morning, attended an event at a Nevada Tesla factory in the evening, and worked with Tesla on AI at night — all in one day.
Musk responded that he'd also spent time at "Twitter HQ past midnight."
"I go to sleep, I wake up, I work, go to sleep, wake up, work—do that seven days a week," Musk told the Journal in 2023. "I'll have to do that for a while — no choice — but I think once Twitter is set on the right path, I think it is a much easier thing to manage than SpaceX or Tesla."
On the Tesla earnings call in April 2024, Musk said: "Tesla constitutes the majority of my work time, and I work pretty much every day of the week. It's rare for me to take a Sunday afternoon off."
