Do you mean something like the end of the Roman Empire which in retrospect can be seen as a paradigm shift? Or do you mean we are going back to the stone age by e.g. destroying civilisation with nukes or similar (all of which could also happen any time with the right volcanic eruption or meteorite impact).
It is quite clear, that without education we are not gonna get more civilized than we are now. On top of that people realize one way or the other that they are ripped of by oligarchs, that masterfully played their power over the last decades to increase the share of money they drain out of the rest of the people. This won’t go on forever and we definitly should think about the effects similar things hat last time when this was the case (pre World War era with it’s rapid industrialization).
