> I don't disagree with you, but I think we can do something to accelerate such process. Maybe not 1,000 years, maybe just a few generations? After all we already made the progress and now need to relearn and rebuild it. Consider as a counter example the Antikythera mechanism[0]. It took well over a millennium for collective knowledge to reach the same point such that similar devices could be created. For immediate survival needs, rediscovery would very likely be quicker. Things like crop irrigation, water management in general, and/or food preservation I imagine would be the quickest to be rediscovered. 0 - https://en.wikipedia.org/wiki/Antikythera_mechanism https://en.wikipedia.org/wiki/Antikythera_mechanism
