Divergence would not occur if there is no outside input, i.e. if there
is a self-contained virtual environment. The Universe could be an
example of this. It wouldn't matter if the two computers were not
running in parallel as long as they ran the same program. I would not
mind if my program is terminated today if I could be sure that it
would run again at some future time, since I would experience no gap
in consciousness; nor would I be aware from inside the program of any
change in processor speed.
