Any Process which contains you up until this point, or Bayesia up until
this point, *not* with a hands-off condition, affects your future
subjective probabilities because you might turn out to be living there -
you cannot distinguish Bens in "interventionist simulations" from Bens in
"top-level Bayesia" or "hands-off simulated Bayesia". "You" are a pointer
state that refers to all the hubble volumes, universes, quantum branches,
simulations, and Processes that have faithfully computed Ben Goertzel up
to this point.
