Hmm, interesting. Okay, if you don't mind, I'll keep that figure
in mind! :-) But it's quite reasonable compared to "day persons":

Exactly right! From the above, it does sound like you believe that
you are the same person you were yesterday (not forgetting for an
instant that one gradually changes, and, I say, changes into someone
else). Right, it *is* a matter of degree.

Yes. And I might argue that the result could easily be a person
that was neither Einstein or Shakespeare. Operationally: after
we finish that horrendous merging of the two, we might have
a dialog with him that goes:
Us: Are you the same person you were yesterday?
Al-Will: Oh yes. That was something that was the same
in my old lives.
Us: If we had asked either Al or Will, before the
merger, what would they have said regarding
how many years it took to become a different
person (i.e. not the same person) through the
natural process of aging?
Al-Will: Well, as Al I would have said <insert answer 1
here> and as Will I would have said <insert answer
Us: It seems to us that the merger changed you considerably.
Would you say that the merger of the 20th century
German speaking scientist with the 17th century British
playwright inflicted more change than either <answer 1>
or <answer 2>?
I cannot imagine Al-Will saying, "Oh no. That was nothing so severe
as becoming <answer1> or <answer2> years older!
Almost surely Al-Will would say that he is not the same person as
either of the two previous worthies.

I quite agree.

I agree. But reducing the two physically distinct processes to
just one, as you understand I have claimed, amounts to letting
the 1.001 person live only 60 minutes an hour instead of 120.
>> Nozick's seriously stupid idea of "closest continuuer".

Oh, he said that if you had n-duplicates made and then died
yourself, that only the "closest continuer" would really be you.
How totally nuts. Why exactly aren't the rest you, who may
differ infinitesimally from the anointed one? <rant suppressed>

Why need only one of you get to be Stuart? From a physicist's
perspective, they're all pretty similar---as they should be: they're
close duplicates after all.

You're very welcome.
