You're asking the wrong person. I haven't seen a single example of a doomer warning that came true. Can you provide one? It seems like society still exists when I look out the window and the impact that doomers assert are greatly exaggerated in every instance.
So are disingenuous or just stupid? Of course society exists still, but what society?
Only the very dumbest think “doom” is some apocalyptic scene from a Hollywood film in which humans are nearly wiped out.
“Doom” is instead when swaths of Roman citizens with rights amidst a powerful, civically and technologically impressive hegemony, over time find themselves reduced to unfree serfs. They and their descendants would remain in that position for centuries until a horrific disease came through and killed so many of them that the serfdom became untenable.
