Climate change isn’t really an existential threat. To be a filter it has to kill all humans and even the bleakest models don’t predict that.
Also for it to be a Great Filter it has to be something that ALL civilizations do to kill themselves. Seems unlikely that all civs wou ld even have analogs to gossil fuels in quantities sufficient to do this kind of damage. And the idea that zero of them actually course-correct when they notice it seems equally implausible
Was doing my masters degree. We’re all talking about some book several people had read. We ask one guy if he’s read it and he says “I don’t like… read books” with the emphasis on those last two words just dripping with condescension. Like read the statement with the subtext of “if I caught my kid reading a book I’d disown him and call him a queer”.
Really inexplicable take in a room full of literally only masters students
