I kind of disagree with that. Yes we have more technology and science, but there are also lots of human processes and social orders (like nations and governments) that don't really change. I'm not sure superior technology guarantees the survival of civilization as we know it in the event of some cataclysm, or wide-scale famine... imagine how many things in the world would be messed up if the US and China were to lose all their value/power in a short amount of time.

Also, I think it's a mistake to assume people were dummies back then. If you think about it, humans have accomplished amazing things over the millenia, and some of those discoveries are still important today (every cryptography book still covers Euclid's GCD in its early chapters). Dismissing them as barely literate IMO is ignoring the important lessons that history has for us.
