I mean on a more global and grander scale. Like the Colonial Era, Roman Empire, Viking Conquest or similar. Events that unfolded over many generations that transformed or affected significant portions of the world.
Lots of things in the mix. Population explosion, industrialized manufacturing, the industrialization of agriculture, unheard of mobility, rapidly expanding energy consumption, science going mainstream, truly global wars and conflicts, the expansion of general education and almost universal access to knowledge. These are all powerful elements that help define the current era.
It would be interesting to know what it all looks like in hindsight after enough time has passed to enable a rational analysis devoid of current politics. None of us will be reading that book.
