Atlas has apparently always been more technologically advanced than the other three kingdoms, though. It's pretty much been shoved in our faces that Atlas is the tech-savvy kingdom. And wasn't it stated that Atlas/Mantle got a head start on technological advancements thanks to the Dust mines they found on Solitas? The only reason that didn't happen to Vacuo is because Vacuo was living comfortably and saw no need to make advancements, while Mantle needed to make advancements to survive the harsh conditions of their region.
