@Methylzero @cstross @iinavpov I think what you state is accurate. It shows to me how he's not a serious businessperson, and treats SpaceX as a plaything regardless of what makes business sense.
Arguably Musk bought Twitter in order to influence political power, and this was successful. So maybe that one's not just a plaything ... except why rename it "X"? That's a very unseriousness decision.
And as for Tesla ... I mean. Come on. Cybertruck? How much less serious could he get?
