He absolutely will. As many journalists have already pointed out (there was a bunch of articles about this exact topic a month ago), members of Trump's circle rarely lasts long, & the few longtime Trump loyalists apparently despise Musk (for example, apparently Musk kept getting into arguments with fellow members of Trump's circle in Mar a Largo, 'cause Musk is an annoying af autist). TLDR, Musk's days are numbered. He served his purpose during the election, and now Trump can send him off into the sunset. Maybe give him a consolation ambassadorship or something.
I think Elon & the rest of the conservative technocrats misjudged Trump's populism as being merely an election strategy/grift. Say what you want about Trump, but I do think he cares about the average American Joe, and wants to do what's best for normal average people. Trump's recent comments about Canada mean he's well aware of what unrestricted 'jeet immigration did to our neighbors up north.
