That made me think, what if technology was developed that allowed a portion of the brain's processing functions to be offloaded to an external system. So, you would copy most motor functions to a "brain emulator" first. And after you have acclimated, you would continue to the copying process (I have very little doubt that if properly done, the brain wouldn't be able to readjust to this, just like a prosthetic limb or "seeing" through stimulation of nerves on the tongue). And this process is gradually performed until the entire "consciousness" is running on the external artificial computer. I wonder how the perception of self would be affected by such a method.
