I don't think he has a 110 IQ at all. At best 90. He surrounds himself with intelligent people so he can feel and look smart. He purchases companies and ideas already built by smart people. When asked to explain things he giggles & stutters trying to sound neurodivergent so no one will question him.

There's the theory that you can't effectively communicate with people beyond a 30 point IQ difference.
If Musk were only a 90 IQ that means he couldn't effectively communicate with anyone beyond 120 IQ which isn't plausible.
PayPal. Tesla. Twitter.
He didn't hire the people who made them successful. In fact, with Twitter, he fired them. 🤷♀️
