When consciousnesses are transferred, it's usually the consciousness of a formerly organic being into a cybernetic body. I'm not a scientist, so I still don't really get it, but it's like the consciousness that develops starts from a model of the old one. At the same time, though, those models continue to exist in the new being's subconscious.

Maybe it just has something to do with the way our bodies are built, more than the other?
