Maybe it doesn't have to be that way.
Maybe there is no necessity to believe that all of us mere humans are a weakness which must be transcended on the progressive path to some as-yet unknowable future.
But it feels like that undercurrent has always been in much techno-futurist thoughts which we can read in Musk's specific interests and grievances. Maybe that is just a problem with a view of history as the product of historical necessity- maybe it's just easier to see when the changes are specific technological changes instead of more abstract political or economic changes.
Anyhow, that's how Musk (and basically anyone who promotes implementing mass, top-down changes to the world) has always felt to me.
