<div>It's the difference between making a copy and destroying
the original, as per the Star Trek teleporter, or making a
copy and preserving the original, as per the Star Trek
teleporter when it malfunctions. In the former case, you will
have continuity of identity with the copy, while in the
latter, you have a 50% chance of having continuity with the
copy or the original.</div>

<p>There is no difference, assuming the 'copy' is of high-enough
fidelity. There is continuity of identity in both cases, has to
be, or the process hasn't worked.</p>
<p>It's the old story of the dividing amoeba. Which of the two
daughter amoebas is the original, and which the copy? Does the
question even mean anything?</p>
<p>Uploading doesn't just imply a continuity of identity, it
necessarily involves it. Otherwise it isn't uploading. Whether
there are one or a million copies of the 'original mind' doesn't
matter (the whole terminology is confusing, in fact. Using the
word 'copy' causes a lot of misunderstanding, I feel*). There is
still continuity of identity. And if you just can't wrap your head
around the concept of branching identity, well, welcome to the
future.</p></div></blockquote><div dir="auto">But there is a problem because if there are multiple copies they are not telepathically linked. Each copy feels itself to be the unique continuation of the original, because that is how our psychology has evolved. This is the case even if each copy knows, logically, that all the other copies have equal claim to be the continuation of the original. Given that this is how human minds work, expectations about the future when there are multiple copies work probabilistically. It is also what happens if the Many Worlds interpretation of QM is true.</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div><p dir="auto"></p></div>
