In the show Emerald City we see many pieces of modern technology in Oz: lightbulbs, electric saws, flying monkey drones, etc. And yet we also see people traveling on horseback with swords. And Dorothy's gun seems like some incredible magic to the people of Oz.
So is there any coherent explanation for the state of technology in Oz? How have they developed electricity and drones without inventing the automobile or gunpowder?
Is it an issue of the cities having advanced technology, whereas the rural areas have medieval technology? That's what it seems like based on the episodes that have aired so far.
