After many life-expectancy-spans worth of narrow escapes, after
thousands or millions of years, wouldn't the probability be pretty high
for my personality/memory etc. to change so much that I wouldn't
recognize myself, or that I could be more like another person than my
original self, and so for all practical purposes wouldn't I be another
person? How do I know this hasn't happened already? If it has, what
difference does it make? Isn't it true that the only realities that
matter are the ones that make any difference to my reality? (almost a
tautology)
