Anyone who unironically calls other flesh-and-blood people "NPCs", is in my opinion engaging in the kind of dehumanisation necessary for mass murder.
Musk has previously professed the belief that we live in a simulation, which also another belief with seriously dodgy implications when sincerely held.
Its not clear to what extent he can step out of these views is it? I suspect he has quite an ironic take on things at times but is also vulnerable to being both very literal and obsessive. I think he might find any narrative that doesn't come from him too controlling, or that he perceives as not coming from him, he can't stand to be pinned down, or to be seen as the same as others. I'm not sure he'll ally himself with a group or movement, not consciously, he seems to like to dodge being classified.
But anyone who you can't say no to is potentially dangerous.
