Reason 3. Time intervals in the computer and in life.

We envision a situation where a person to be simulated is scanned and the data are used to create a representation of the subject in the computer, encoded as some kind of symbols representing numbers, the numbers in turn representing coordinates of points in phase space for the simulation. The program then has the computer generate successive states of the simulation, i.e. successive arrays of data. Each later state of the computer corresponds to a later moment in the "life" of the simulation, the interval between each successive state in the computer being constant according to the capability of the computer.

Now, assume the original lives on, while his simulation is being run on the computer. The simulation "lives" like a film with frames at non-zero intervals. The original lives in some fashion not presently understood--possibly in a continuous fashion with no gaps, or possibly jumping each time to an appreciably different state with nothing in between. Even in the latter case, however, it is exceedingly unlikely that the intervals between successive states would be the same for the original and for the simulation. Hence, it seems to me, the simulation cannot be faithful to the original. Again, we can't know yet how important the differences may be, but there will surely be differences.
