@Thal:
Out topic:
What you are describing is not them not having the tech, it's them having low prod, low food, low commerce low health cities.
as you said, if you were to change those un-educated women, un-fed child, they'll quickly get back to tech level (not in robotics and computer science but all industrial era ...certainly)
(and look at some other countries : India, China, Brasil.... they solved some issues and lo. now they are on par with the developped countries in almost all techs)
The issue with civ is trying to mimick the historical development as a continuous progress while history was in fact full of long slow progress, stagnation, recess, sharp progress, recess, stagnation, slow progress. (China went to top of techs around 0AD ; they progressed/improved their tech a bit in the following millenia but only incrementally. The Roman empire was followed by the dark ages... during which most knowledge was LOST. the late-empire Roman legions would have kicked ass to any knight kingdom... until maybe the full plate armor was invented, or maybe the pike-square).
the difference between Babylonian heavy cavalry, Greek Heavy cavalry, Cataphracts, Early Dark age knights, templars... etc was minute until the invention of the full plate armor.. and maybe of the gendarme
Caesar and Alexanders' (and Sun tsu) strategy books insipred even Napoleon... nothing was invented.
until the machinegun, the mongol horse archers would have razed anybody (sure, some heavy guns and rifles would have render their victory more costly, but they would still have won) see the power of lancers in the napoleonic era, and imagine lancers that starts shooting arrows (napoleonic cavalry had only 2/4 pistol shots... not comparable to 20+ arrows.
And this until the scientific method and the patent system. After that time, there was a progress in science that can be almost described as the one present in civ.
but it would be hard to code, so why not, the current way is the least bad one
