to successfully emulate a brain, we might need to emulate this wild neural randomness. However, that seems to remove the possibility that the emulation will continue on as the original person. Perhaps our very effort to emulate a specific human brain results in our producing an entirely different person altogether.

If noise is essential to central processes in everyday human cognition, then (as a result of this noise alone) an emulation would be no more different from its original mind as any person is from his or her (recent) former self.
