it’s curious if you try to think about it, what exactly is Trump interested in musk? I don’t think it’s his money, I think he likes the way he operates, he’s a doer. Anyone can hire a few guys and use ai to start rooting thru gov agencies, but the way musk does it with a sense of urgency is what Trump likes.
What do you see musk doing beyond doge? I feel he’ll be happy to go back to his quiet trillionaire life once doge is finished 
I don't think Trump is interested in his money, but I think he understands the importance of his money to the 26 midterms, and beyond.
I don't think Musk has any interest in a political post post Doge. But I think him remaining on good terms with Trump, being somewhat successful at Doge, and becoming a sort of cult hero on the right will lead to being a long term behind the scenes Soros type donor/kingmaker for years.
