Eh if anything will off us as a species I’d hope for AGI with full on SciFi applications (e.g. evolving into a borg mind/post human world) because at least then someone can tell the story of how we all fucked up.
Abother note: All life ends but all you can do in this existence is to be kind and help others at the end of the day. I think we as a species suck at that but do your best in the wave of nihilism and suffering and it’ll help even a tiny bit.
