14th century Renaissance is a good long way from the 10th century or RL history or what Westeros resembles, we didn’t have printing presses at that point for one thing to disseminate information or encourage literacy on that scale nor the development of a burgeoning merchant middle class to develop industry or provoke social mobility. I believe gradual transition is needed, from technology, to economy, to society, to sustain such a radical change without falling apart.
