Like most of the "brilliant" people I know that fit the profile you're describing, the usually build product in the same way they maintain relationships, chaotic.
Most people really just DGAF about politics in US. The (few) smart people working for Elon are those who are really into whatever technology and just like to play with toys while getting paid. I used to work with such a dude a few jobs back in my aerospace days, guy was multi talented across both software and hardware, and could easily be making bank at Apple Amazon Google in one of their edge programs, but was content with getting paid like 80k a year in 2010s in a fairly high CoL area with an hour commute all because he got to play with a rather big UAV.
So this is in no way a `no true Scotsman` fallacy. Being able to be well read is a product of having intelligent people in your society, people who make hard things accessible, make it learnable, but it does not itself make you intelligent.
