Go figure! Who would ever have guessed determinism and chance were difficult to marry...
Then you're refuting MWI as not being able to correctly renders the probabilities, right? Is measuring spin up under MWI has a probability of one or 0.5 under MWI?

You can use a tele-vision system, and communicate by SMS, but unless you build a new corpus callosum between the two brains, and fuse the limbic system, by comp, the two "original" persons have become two persons, having each its unique experience. That follows from mechanism, and so P(W xor M) = 1, and P(W & M) = 0, as no one can open door in Moscow, and see some other city in the direct way of the first person experience. >>> >>> >>> It follows from physics. >> >> >> We don't know that. > > > Then why did you assert the necessity of a physical connection: "You will need a long neck to attend a conference in Moscow, and a party in Washington." > >> We just assume that the physics is rich enough to implement locally universal machine, so that comp make sense, but then we arrive at the computationalist difficulties.

If that is more than just an assumption it is because it is relying on the physical basis of mind.
