I disagree with the vision. The best analogy I can think of right now is high school kids renting a hotel for a party and trashing it and then doing the same thing next week. That’s humanity right now.
There is no Planet B until we build a mutualistic relationship with the one that created us.
And yes when I say “there is no Planet B” I’m being vaguely spiritual. I believe Earth is a creature and somehow won’t allow one of its creations to explore the stars until that creation learns mutualism. But I’m also being pragmatic: A) colonialism was a big motivation in our last 2 world wars and we still have intense colonizer memes circulating through our societies B) we now have the means to destroy ourselves thoroughly C) Mars is the crown jewel of potential colonies right now.
