There is a recent Atlantic article that captures Elon nicely from a psychological point of view.

(Note., this author called this "brain damage" but it is not. It is just a well-known and understood personality change for a normal personality and brain.)
I wrote the following article on Trump which correctly called him a dyslexic narcissistic schizoid psychopath. A very evil man no good to any human society. Psychopaths cannot be cured. They just get worse:
Elon is neither dyslexic nor a psychopath (or sociopath). He needs to find a person (or two or three) he can trust to suggest other words or actions to him (or not) in the moment he would desire such suggestions.. Such people exist. (I am not one.) In some circumstances he needs a delay line that gives him better words or actions.
Finally, sociopaths and psychopaths SHOULD be weeded out of corporations and other positions of power:
