"Its actually difficult for me to believe that any elite would be stupid enough to think they could survive an earth environmental catastrophe in space." You underestimate the raw power of untethered hubris, fueled by venality.

Excuse me but humans have already made immense technological progress through science, creativity, effort, and not listening to doubters like you. What on earth are you talking about and how could you speak so carelessly about such a crucial issue? And where the hell is this bs narrative that it's just a bunch of elites who want to get off earth ? The issue is ensuring the survival of humanity in the current braindead situation that all our eggs are in one basket. Any basic strategy course will tell you this is a good way to lose all your progress after a few iterations. I'm starting to wonder if there's a campaign to discourage the mission to ensure humanity's safety. Hit me back in 3 years when this hits the news and thank me then but it will probably be too late.

It's a catch all metaphor. Most likely we will see some version of fortress Europe and the US devolving to frontier economy. Frontex is already getting bigger budgets, more boots on the ground and better kit with each passing year.

You're making claims discouraging people to seek a solution to a VERY important issue. Kindly show some substantial info demonstrating evidence humans would be reliant on Earth. The entire point of such a mission is not to be. And lots of materials exist elsewhere. Again kindly show us proof of your extremely dangerous claims.
