 "He was never actually diagnosed as a kid," his mother says, "but he says he has Asperger's. and I'm sure he's right."  The condition was exacerbated by his childhood trauma.  Whenever he would later feel bullied or threatened, his close friend Antonio Garcias says, the PTSD from his childhood would hijack his limbic system, the part of the brain that controls emotional responses.

     As a result, he was bad a picking up social cues.  "I took people literally when they said something." he says. "and it was only by reading books that I began to learn that people did not always say what they really mean."  He had a preference for things that were more precise, such as engineering, physics, and coding.

     Like all psychological traits, Musk's were complex and individualized.  He could be very emotional, especially about his own children, and he felt acutely the anxiety that comes from being alone.  But he didn't have the emotional receptors that produce everyday kindness and warmth and a desire to be liked.  He was not hardwired to have empathy.  Or, to put it in less technical terms, he could be an asshole.
