Musk is being played for a fool and he doesn't see it. He's being treated the same way you treat a 5 year old who needs to be kept busy, lol.
But for the rest: more stimulants/ketamine binges.
Once you become a top-level politician, that is your primary identity. Everything else you do becomes a side business. If Musk remains the CEO, everyone doing business with Tesla understands that they are dealing with a US government official. That's going to be a big business risk, especially outside the US.
It seems like this would be very good for business, especially considering the billions in revenue Tesla already earns from the u.s. government. If I were a Tesla competitor I would be worried.
