I'm not sure why you're responding as if my comment is some sort of hopium. I'm saying that if we don't stop ourselves from making Earth uninhabitable to us in the very near future, that this is the peak of technological civilization on Earth for all time. Whether human descendants or another sapient species comes out of the climate turmoil and tries to advance again, they're gonna hit a wall.
All our ambitions and dreams for the future hinge on reversing the damage we've done.
