I think it's partly he really believes that because he is the richest person in the world he is the smartest person in the world so he needs people in charge who understand that and defer to him. I think he's basically said he thinks that autistic high intelligence people ought to be in charge of everything because they know best.
Apparently it was his daughter transitioning that really sent him off the rails. I had heard he selected for boys when impregnating women (I won't call it fathering children) and wasn't sure it was true but have just now seen all his other 11 kids are male. So yes, he has been selecting boys because he thinks they are worth more than girls and because presumably he sees it as proof of his virility. So no wonder he was fuming when his daughter turned down the amazing privilege of being male
