Man, just once, I'd like to see a billionaire that decides to spend enormous amounts of money on cool shit, without also being a terrible human being. Basically thinking of Musk, but the version of him that most people thought he was back when SpaceX was first making waves. That was all ruined by the fact that he turned out to be a Nazi.
Like, if this guy has $300 billion, I wish he would just get it in his head one day that he wants to see real high speed rail in the US and just throw $100 billion at it to force it to happen. Not because it's profitable, but because it's cool, and having $200 billion vs having $300 billion makes absolutely no difference to anything.
