the fact that different data streams (like one coming from Washington

Washington or I am in Moscow) when the calculation is concluded.

Well of course you can be duplicated!! I find it astonishing that in the 21'st century
the average person still thinks this question deserves further debate.

must be duplication of the quantum state, so that the no-cloning theorm
applies.
If you need to stay in the same quantum state to retain your identity then you would be
changing into a different person many millions of trillions a time a second. And if you
never changed, if you always remained in the same quantum state, then you couldn't
think, thought needs change.
But there could be a difference between unitary evolution of your state (which presumably
Scott considers to still be "you") and a non-unitary duplication.
