Is Westeros stagnant?

Stagnant society... 
Maybe not for long.

Many have asked why this world of Planetos is stuck in the Middle Ages. It must be mentioned that Westeros has already got the means to develop better technology but strife and many wars prevented that from going ahead. On our world, China created black powder in the 9th Century and from this, the fire lance was made, and soon other weapons had been invented, while the earliest types of guns appeared from the 15th Century. So in Westeros, and other places,  it isn't gunpowder they have but wildfire. So we can imagine that some bright spark will use the knowledge of wildfire to develop firearms in their future. That world has lost technologies such as Valyrian steel and glass candles. Why hasn't anyone considered making bikes or trains, because they do have wheelchairs for the disabled. It might be that they will, as anyone can guess, because in our own history, the Romans had the knowledge of steam engines but this technology didn't kick off until so many centuries later that started the Industrial Revolution. In our own society we had a stagnating period for thousands of years although the wisdom of high technology sat there in old books, just as it might in that world because the Citadel have a vast and private library.
