Ancient vs Medieval Makes no Sense
The biggest shifts in the organisation and complexity of human society are:
- The shift from hunting and gathering to agriculture, accompanied by the Neolithic age of explosion in tools and technologies. This age also marked the first time humans transformed substances not just in their shape but in their form like make pots from clay, making ceramics, tiles, metalworking, etc.
- The shift from agricultural tribal societies to 'civilization', also accompanied by the development of writing systems, astronomy, mathematics, cities, complex administrative states and so on.
- The shift from an agricultural civilization with kingdoms and empires to an industrial civilization with modern nation-states, which as we all know involved massive developments in technologies, philosophy, legal and political systems.
- AI, internet and similar technologies may soon lead to another age.
