I just don't understand why people make these arguments. When people speak of "humanity" they don't mean "the human species". They/we mean of "human society", our current variant, which just invented computers, artificial intelligent, and until very recently seemed set on ending all resource scarcity, curing all diseases, and becoming inter-planetary. Will humans survive somewhere in the climate as our ancestral species did before us? Of course. But losing 2000 years of societal progress is not something to just waive away as nothing. As long as we are succeptible to a tiny rock floating in space swiping our little planet and wiping out all of us, we must progress technologically, and a regression to merely surviving and dying of a broken ankle is not an answer.
