If we knew for a fact that on the other side of the ocean was a place that had no food, air, energy sources or practical means of return and where touching anything in the environment will severely injure you from the intense cold, I don't think many people would have done that either, and those who did would not have living descendants today.
But anyway, if Musk is talking about the year 2500, yeah, I'll admit I have no idea what anything will be like then. And neither does Musk. Tautologically, nobody can really predict much outside of the foreseeable future. We could have perfected cold fusion by then, or a major cataclysm could have decimated the human race and left us in a new ice age. I don't feel any more qualified to say what that year will be like than somebody in 1511 was to predict what we'd be doing nowadays.
