Personally I don’t think the idea of transporting memories makes sense. Memories are a connection our cells in our heads made in response to stimuli. I think you can have an identical clump of cells and they have two similar, but different, memories attached based on the person’s experience. Like, my favorite food is double chocolate cake, your favorite food is your mom’s meatloaf, our brains’ cells look the same but what we are experiencing consciously when those cells interact is completely different. Because the cells are doing the exact same thing, right? It doesn’t make sense that every individual thing we experience would have a slightly different cell.
