We may well be. As we careen towards great filters like the climate crisis (and running out of fresh water for agriculture) we may drive ourselves to extinction, or (if we're... lucky?) close enough to extinction that all our present culture and most of our scientific knowledge is lost.

The version in which one out of eight people survives, is the good ending. Then we might be able to adjust our institutions to the smaller population. But expect all the Horsemen of the Apocalypse to put on a show, and claim their due.

But here we are under Trump dealing with the same kinds of problems that arose under Hitler and Mussolini and countless other dictators. We're going to keep doing this thing where we let small factions game the system for themselves until we figure out how to effectively prevent it. If we don't figure it out then in a hundred-thousand years, when the atmosphere has healed and the plastic has mostly been cleared from nature and we start populating again, we'll still have the same problem... or maybe not. Maybe we'll have evolved a bit.

(Homo Erectus experienced a similar period of scarcity and a population of less than 10,000 until the world got more habitable, and they got pushed out by competing hominids like us.)

We need to end the war of kings and resolve our grievances so we can face the ice zombie army from the north... and unlike Season 8, we're pretty sure killing the Ice King isn't going cause an ontological collapse the way killing Sauron collapsed the organization structure of the goblins and they fled back to the mountain caves. (GRRM was all about subverting fantasy tropes that didn't mesh with real-life experience)
