I thought it gave back, ironically, some humanity to the man. That article, and a few budding psychiatrists here, seem to prefer the darker reasons for an unusual man.
To quote Garth Zietsman, a person who probably matches Musk for IQ, "Only one in a million people are this intelligent. They are seldom understood or appreciated. Most feel profoundly isolated from society - even when they are appreciated. A large proportion of this group opt out of society and never make revolutionary contributions in the standard academic fields or professions. It seems to be very difficult to motivate them to play the academic/scholarly/professional game because they regard even the most venerable of traditions and institutions as absurd or silly. Consider that even the mind of the average professor appears to them like the mind of the average bricklayer would appear to the professor."
