[@Kho]And yeah, the king of england in a mud house was more technologically advanced than the roman emperor. I mean, my house is shabby if compared to Babylonian palaces, that doesn't make the Babylonian palace more advanced, they are more complex, and complexity exists without tech.

No, there is a difference between a society having the technological knowledge and physical ability to create works of architectural glory, and having neither. King of England had neither, you - given enough money - do. Babylonians, Ancient Egyptians, Assyrians, Romans, Greeks etc. all had the technological knowledge and the power to. This makes them more advanced than 4th/5th even 9th century England.
