So, the idea is to create a society that survives even this scenario. Distributed Library's,that survive Alexandria. Rugged Tech, that can be made even with just sun power and leftovers. Social networks, that allow for continued cooperation even during times of enforced isolation by disease and war. Social networks that enforce social behavior, by the world bearing witness. Tech that evades the control of the temporary mighty, warlords and priest castes, that try to "stabilize" society by freezing it between the holy cycles of overpopulation and civil war. Lots of work. Doable Work.
