Maybe you should perhaps give some credit to the guy who has repeatedly proven he can run and exponentially grow extremely successful businesses?
Musk bought shares in Tesla as a venture capitalist, not as a founder or manager. As CEO, he seemed to spend a lot more time tweeting than one would expect a CEO to have time for. I also have doubts he does much actual work as CEO for SpaceX, Neuralink, Solar City, or The Boring Company.
Think about it. If Musk spent only two hours per day doing some nominal duty (like sitting in on one meeting and reading emails) for all the 5 non-Twitter companies he is CEO of, that would be ten hours. I've never heard of an actual CEO job that could be done in 2 hours per day, or even 8 hours per day.
Plus, even this 2h/day joke level of commitment would seem to leave Musk with little time for his newest toy, Twitter, or the time he spends tweeting, or his sexual flings. If he's really sleeping in Twitter's San Francisco offices, who's running the other companies?
All this suggests to me he delegates most day-to-day running of businesses to executives, and is generally an absentee CEO. Musk is sort of like the queen/king of England - a symbolic role that generates lots of buzz but does not do the actual work of leadership. To think otherwise is to attribute some sort of superhuman ability to someone who regularly makes very dumb mistakes ("funding secured" tweet, purchase of Twitter for too much money in order to make a 4/20 joke, thinking the Boring Company would ever work).
The growth of Musk's businesses is less a testament to his personal genius as a manager, technician, tactician, or leader than it is to the fact that his businesses have had access to lots of venture capital and investment markets capital, and that they used these funds for R&D instead of dividends, buybacks, earnings manipulation, or executive compensation like a lot of peers do. If Musk forced them to behave this way, that's the credit he is due. I doubt he could manage a McDonald's.
