These are all good points. As for Brandon re-using that idea, I agree that he generally doesn't do that, but we are also seeing more and more connections between the worlds, so I could just see Mistborn characters getting to Roshar and asking everyone why they aren't writing on metal.

So perhaps this topic has been brought up before, but I'm pretty new to the game and I haven't seen it, so I'm bringing it up myself! We know that in Mistborn, Ruin was able to subtly change text so that it's meaning changed over time, requiring text to be written on metal to be preserved. Could a similar thing have happened/be happening on Roshar, only with Odium doing the tampering? This quote from one of Brandon's signings is what caused me to think about this: "They do say that--well let's just say that some books exist in translation over the centuries with the primary text having been lost, or things like this." (This was in regards to the in-text book Way of Kings and its meaning over time). Will writing on metal become a necessity in the future? Could this have anything to do with the origins of burning glyphs? As a more side question, would it be possible to soulcast something into atium? My first thought was no because atium had to do with the power of Ruin, but thought I would ask about it because that could raise some interesting possibilities when worlds start to collide.
