But if we become a new person every time a particle in our head changed state we'd become a new person about 10^43 times a second. and the very interactions with the environment that make them > quasi-classical will ensure they are not identical even at a much higher > level than the molecular. > The duplicates would need some sort of feedback mechanism to keep the two brains in synchronization, non linear effects would amplify tiny variations into big differences, but that is a engineering detail and this is a thought experiment, so we cut back on needless complications.
