That's correct. In both QTI and QS one assumes conditional probabilities.
throw away the branches in which you don't survive and then you conclude
continue to survive into the infinitely far future (or after performing an
large number of suicide experiments) with probability 1.
But if you use the a priori probability distribution then you see that you
of versions of you that survive into the far future is almost zero.
What does "the measure of versions of you that survive into the far future
is almost zero" actually mean? The measure of this particular version of me
typing this email is practically zero, considering all the other versions of
me and all the other objects in the multiverse. Another way of looking at it
is that I am dead in a lot more places and times than I am alive. And yet
undeniably, here I am! Reality trumps probability every time.
