Maybe people aren't into imagining the future. Not really. I'd like to assume that of those who do, if they were asked to project out, 1000 years into the future and make a guess about what those people will be like, that they'd at least imagine the conclusions they arrive at about what's best for people, might be different from ours. This assumes the vast infrastructures we've inherited are maintained or improved on and they aren't regressed back to some proto-agricultural bands of tribes, wandering aimlessly. That they've, as progressives like to say, gone "forward". Well, what would they think of us? How might they be different? Will they be all mongrelized into some singular race? Impossible. Why then aren't the mongrelized nations already ascendant when compared to those who aren't so mongrelized? So, maybe there will only be a million or tens of millions of people left, since they decided to mass exterminate the planet (?). Will they laugh at us and think, what a bunch of dumb asses they were, to try to navigate the competing interests of billions? In all the ways I could envision those people, I can't imagine a single one will say that what America and western Europe are doing today is wise, at all. Can you? Even as a non-white, in your heart of hearts, do you really think people that far in the future (being even more futuristic than we are now), will keep on our current trajectory, even the slightest bit? That's how they make all these ridiculous sci-fi shows like Star Trek and The Expanse seem, but no, that's just absurd. The races will separate again, given enough time. Especially if they're spacefaring. Only question is, how will we do it? Will it be bloody or will it be reasonable, for once? If bloody, I can easily see those proto-agricultural tribes being the norm again. Anyway. Those are more thoughts of mine.
