Well if you spend some time theorizing a model of a brain digitizer that operates within known physics constraints it's not an easy task getting just the molecular and atomic digital data. You have to sample over a period of time and space using photons and particle beams. This in itself interferes with the sample. Then say this sample is reconstructed within a theoretically capable computer, the computer will most likely have to operate in slow time to simulate the physics of all the atoms and molecules as the computer is itself constrained by the speed of light. I'm going this route because I don't think that it is possible to get an instantaneous reading of all the atoms in a brain, you have to reconstruct over time and space. THEN, this is ignoring the subatomic properties and forget about quantum data sample digitization I think it is impossible to get an exact copy. So this leaves you with a reconstructed approximation. Exactly how much of this would be you is unknown because any subatomic and quantum properties of you are - started from scratch - this includes any macroscopic and environmental properties of subatomic and quantum and superatomic molecular state and positioning effects. And if the whole atomic level model is started from scratch in the simulator it could disintegrate or diverge as it is all forced fit together. Your copy is an approximation of which it is unknown how close it is actually of you or if you could be even put together accurately enough in the simulator.
