Yeah, there are faint mentions of moon colonization from Musk, but more often than not he talks about Mars.

I do agree more and more that Musk is a grifter (look no further than Twitter), but SpaceX seems to be one of his ventures that’s not a grift. The technology actually works (falcon 9 works, dragon works, Starlink works), and I don’t see what kind of financial gain he has in going to Mars. Possibly hoping the government subsidizes his Starship rockets that he then will use for contracts?
