Elon Musk Doubles Down on Mars Dreams and Details What’s Next for SpaceX’s Starship

Great, he has a rocket. But he doesn't say anything about what'll be in that rocket.

I say let him have at it!

If he fail, we'll just roast the shit outta him.

If he succeed, we might get something useful (ignoring all his gloating).
