Elon talks in a simmilar way, but then i saw more and more episodes where he starts talking fast. Especially when emotional. Once saw Lex too, speaking fast, but then he kinda ,,went back to the character". Then, there is someone like Ben Shapiro. And ofcourse, honerable mention, Joe Rogan when stoned.
I doubt Rogan has any level of Asperger's at all, considering he has been an MMA fighter and TV host. For Musk and Fridman it's harder to say.
He is pretty knowledgable about AI and even philisophical concepts of neural networks and their implications. The more it surprises me how poorly prepared he came across in that interview
