There was the Renaissance, The Industrial Revolution, the Information Age, and now, the Age of Entitlement.
People need to move forward; or just like those large, sprawling civilisations that came before; this current one too, will collapse; except it will be due to the strain of mediocrity.
None of those were predictable from the perspective of the previous one; so there's no reason to believe we can accurately guess what's coming. Fun to try though.
