Yes, I meant protoplasm.
If I knew that I am currently running on a silicon chip (Gunm-style), then I would be highly confident that replacing that chip by another, identical one, preserves my identity, because it's the same configuration. Moreover, replacing my old chip by a newer one, before the physical deterioration significantly affects the actual software processing, probably would work as well.
But if we're talking about running my software on a different chip through, say, a virtual machine that emulate my original chip, then I would be less confident that it would still be me. As confident as I am that, an EM of my current wetware would still be me. Which is, currently, not confident enough to make the leap.
Ah, and if I do learn that I run on a chip, I won't turn crazy. I may be worried if I knew my wetware self were still running around, and I may not tell my mother, but besides that I don't really care. If I knew that my wetware self was "dead", then I would wonder if I should feel sorry for him, or if I'm actually him. Because I value my life, I know that my wetware self did too. But I'd probably get over it with the knowledge that the rest of the world (including my family) didn't lose anything, (or at least they wouldn't suspect a thing).
I'm confident an EM would not be a PZombie.
As I often say; you are not your meat. You are the unique pattern of information-flow that occurs within your meat. The meat is not necessary to the information, but the information does require a substrate.
Consider the following set of statements:
1) "I am my meat."
2) "I am the unique pattern of information-flow that occurs within my meat."
3) "I am the class of patterns of information-flow that can occur within meat, of which this unique pattern is one example."
4) "I am the class of patterns of information-flow that can occur within any substrate, of which this unique pattern is one example."
5) "I am all the matter and energy in the universe."
What sorts of experiences would constitute evidence for one of them over the others?
1 v 2 -- is your "meat" persistent over time? (It is not).
2 v 3 are non differentiable -- 2 is 3.
4 is implied by 2/3. It is affirmed by physics simulations that have atomic-level precision, and by research like the Blue Brain project.
5 is excluded by the absence of non-local phenomena ('psychic powers').
I agree that my meat does not persist over time.
The class of patterns of information-flow that can occur within meat includes the pattern of information-flow that occurs within your meat. 3 therefore asserts that I am you, in addition to being me. 2 does not assert this. They seem like different claims to me, insofar as any of these claims are different from the others.
I'm not really sure what non-local phenomena are, or what they have to do with psychic powers, or what they have to do with the proper referent for "I".
Missed that about the class. Makes a difference, definitely.
Two options: trust the assertions of those who are sure, or learn of them for yourself. :)
