Ehh, disagree, the species will be fine, and the tendency towards civilization building seems to something we’re inherently built towards, so I’m not especially worried about that either, especially given the recovery that was seen post Bronze Age collapse.

As to the survival of current civilizations (or even preservation of the skills and standards achieved through those civilizations)? Oof, thing aren’t looking super great on that front, likely to be a pretty turbulent century or two, but I’m confident that they’ll be something recognizable on the other side.
