<s>[INST] And you think that it can basically be funded by people spending maybe a couple hundred grand on a ticket to Mars? Is that price about where it has been? [/INST] Well, I think if you say like, what's required in order to get enough people and enough cargo to Mars to build a self-sustaining city. And it's where you have an intersection of sets of people who want to go, because I think only a small percentage of humanity will want to go, and can afford to go or get sponsorship in some manner. That intersection of sets, I think, needs to be a million people or something like that. And so itís what can a million people afford, or get sponsorship for, because I think governments will also pay for it, and people can take out loans. But I think at the point at which you say, OK, like, if moving to Mars costs are, for argumentís sake, $100,000, then I think you know, almost anyone can work and save up and eventually have $100,000 and be able to go to Mars if they want. We want to make it available to anyone who wants to go. It's very important to emphasize that Mars, especially in the beginning, will not be luxurious. It will be dangerous, cramped, difficult, hard work. It's kind of like that Shackleton ad for going to the Antarctic, which I think is actually not real, but it sounds real and it's cool. It's sort of like, the sales pitch for going to Mars is, "It's dangerous, it's cramped. You might not make it back. It's difficult, it's hard work." That's the sales pitch. </s>
