This sounds a bit like the argument which says that if QI is true, we
could never fall asleep, since we don't experience unconsciousness and
therefore we would only experience the worlds where we stay awake
indefinitely. That argument is invalid, unless we are falling asleep
permanently, i.e. dying. If we fall asleep and wake up again, or
experience amnesia and recover, then the worlds where that happens are
*not* excluded by QI. They are simply worlds where you have a gap in
consciousness, as valid when you are calculating subjective
probabilities as the (in general far less common) worlds where there
is no such gap.
