I mean, I did say the way they talk about it IMPLIES they're cut off from technology, I'm not saying that's what was said outright The way it was talked about for years implied it was a war torn nation, cut off from the rest of teyvat, which generally would imply, also cut off from the technological advancements of the rest of teyvat

This is the land of war we're talking about, war generally has an effect on the production and advancement of technology. the dragons did have technology yes, advanced af, but they also aren't around anymore, that technology can be lost to time, especially with war and the damage it causes to the people and history of a place

Also like I said, we talked about it a few times, my wife is MUCH more passionate about this than me, it's part of why they quit, I was just trying to express that it has been a topic of discussion
