> "Collapse" is maybe hyperbole in this case, if it's building on our own history to extrapolate forward.

In the story, "at some point" generally involved technologies we are currently incapable of; the greater technology actually facilitating the greater collapse. Which at the most obvious included nuclear catastrophe.

I think my contention is with "collapse" rather than something like "crash". The latter implies a cyclical downswing (reasonable), the former implies the absolute end of a cycle through the non-viability of the prior order. One means "start the round/match over," one means "find some wood to start carving a new board and game pieces". The new game probably won't be recognizable, and you're talking about not just the events but the setting and context being unfamiliar. Every civilization goes through that? I suppose, but only because every life-bearing planet goes through that, civilization-bearing or not.
