This question is ignoring the obvious problems of a shard blade on Earth. What would happen if a shardblade stabbed through an isolated computer that has the only source of the AI? And the AI is trapped in said computer?
Very specific question, sorry.
I always assumed that the gloryspren swirling around Dalinar in RoW were his armor spren. I was pretty disappointed when that didn't happen, because it seemed like they had no purpose other than to make a really cool visual.
In Oathbringer, Dalinar goes out into the storm to find his dinner knife. When he comes back, he sees a strange Spren in the distance. He does a rude gesture at it, and then goes inside. What is it?
