Elon is hyper focused on one task. Go to mars. Everything he is doing is that. Orbital network so you can talk to each other. Boring company to dig places to live as the surface is probably too harsh. Electric vehicles and solar to move around the surface. Reusable rockets to dramatically lower the costs going there and back. To move the amount of material to build a city there is going to be daunting the rocket cost was one of the large outliers. Think he said that cost had to come down 10-20x for him to make this happen. SpaceX is doing research and they are willing to blow up rockets to do that. NASA seems to have lost the taste for that years ago.
