Yes and I thought I did show you that which physical implementation is used doesn't matter ? or would you say you would accept a digital copy of yourself on ARM but not on Core 2 DUO ? > > > >or to point on the point that you don't > > understand in the UDA. > > You told us you have a problem with the UDA 6, I have provided an > > explanation, but then I am not sure if this satisfies you or not. > > Rfefrerring to the environment does not change the reasoning, unless you > > put non-turing emulable feature in your brain/ environment (but then you > > say no to the doctor). > > > >>> > >>> > >>>> > >>>> In terms of Bruno's teleporter, one might say yes accepting that > >>>> there would be > >>>> a one-time gap in consciousness (ever had a concussion?), but one > >>>> would probably > >>>> hesitate if the there was to be a gap every 10ms. > >>> > >>> > >>> From the ultimate third point of view, there are no gap, or there are > >>> gaps everywhere, that could depend on the topology or topologies you > >>> will extract from the numbers. > >> > >> In order to teleport me, my state must be determined.
