I don't know if we can though. We take our cultural narratives with us and they'd come with us into the new world. Even the idea of starting from scratch is part of our cultural narrative - this idea of a reboot, or a Utopian vision that we can do better than this. Maybe you're right though. Still, I'd prefer diplomacy. I think we do a lot of things right as a species and we amplify the things that are wrong so they seem worse than they are. But that could be naivity on my part as well.
