- But, reproducing my particular sequence of base pairs would not bring me back to consciousness. The result would be somebody else.
Debatable. At least in the (purely hypothetical) case of making a perfect copy of someone, you can say it's the same person or a different person, and both statements could
reasonably be considered correct!
(Just copying the DNA alone won't give you a perfect copy, of course; identical twins with identical genes still have different fingerprints, among other things.)
You can say the copy is a different person because your perfect copy would (obviously) be a separate individual from the original, but that's more of a labeling-for-convenience. In fact, both copies would be identical, and either (or both)
could be considered the "real" person.
Which is why
teleportation is indistinguishable from destroying the original when making a copy.
- And, if we kept reproducing my particular sequence of base pairs, we'd keep producing new, and different, particular consciounesses.
Because each one would be a separate individual; not because there's any meaningful difference between them. If they were perfect copies (not just genetic twins), they'd all
effectively be you, even though there'd be more than one.
I'm saying that these all represent potential selves that will never exist.
Ah, but there's
still a finite number, whether or
not you consider them different people or separate instances of the same person. The number of copies you can make,
even in theory, and
whether the base pairs are identical or not is
still finite! It is a (very small) subset of the
possible arrangements of all particles in the habitable portion of spacetime!
I mean, seriously, whether you realize it or not, you're arguing for a much
smaller number than I was already offering you. If you take every possible arrangement of particles in the universe that match your genes (which is the limit of what you're talking about), and multiply that by the number of possible arrangements of the human genome, you get (
by definition), a subset of all possible arrangements of all particles in the universe. An incredibly
tiny subset, in fact.
And, in that sense of "potential," there are just as many potential selves as there are digits in the square root of 2.
That would be true if and only if the number of arrangements of particles in the universe were infinite. But it's not. We've been over the Planck length dozens of times, Jabba. You can't just ignore physical reality and proclaim that motion is impossible, or whatever variant of Zeno's paradox you're favoring this week, because, according to the scientific model, the universe doesn't work that way. If your probability of existence were zero, then motion would also be impossible. But it's not, so it's not. This is the twenty-first century AD, not the 4th century BC. Lets stick to arguments that aren't centuries-stale and silly.
