> Then you kill (choose your method and make it quick) the natural brain - instant swap? Or is there something different? Where does the "consciousness" go? If it is different, why is it any different than the "near-instant" swap? This seems to be a non-sequitur. If we simply understand consciousness as a property of the brain, as long as you have 2 copies of the same brain, you naturally have 2 consciousnesses. The 2 may be equal or not (most likely not, given that random noise is extremely likely to play a role in brain processes), but they are definitely not a single object.
