When​ duplication machine​s are invented no doubt the entire English language will ​have to ​undergo a major overhaul, particularly in the way pronouns are used;


Computer scientists, and users, duplicate programs and machines all the time, and biological reproduction is arguably a variant of this.

The only thing you need to do is to be a little bit more cautious in the 3p-1p distinction.






but I fear some will still insist in asking nonsensical questions like "what is the probability "you" will see Moscow?".


This reminds me that you have not yet answered my recent question. Do you agree that the guy in Helsinki can expect to drink a cup of coffee with certainty (modulo the (default) hypotheses) when we add in the H- WM step 3 protocol that both copies will be offered a cup of coffee, in Washington and in Moscow?

Is is OK to deduce from step 1 (we survive simple classical teleportation with P = 1) that P("the H-guy will feel drinking a cup of coffee") = 1?


My question was:
"Let me try something different; but I will go with numbered questions. I will proceed when I get the answer.

Question 1 (30-07-2016)

We are in the step 3 protocol (read and annihilated in Helsinki, copied in Washington and Moscow soon after).

Now, we add that in both Washington and Moscow, you will receive a cup of coffee.

Do you agree that in Helsinki, the H-guy who believes he survive teleportation/duplication, can expect to certainly drink a cup of coffee soon (assuming computationalism, the correctness of the substitution level, the default hypotheses, ...). That is, would you agree that in Helsinki P(H-guy will-feel-drinking-coffee) = 1.

I think you have already answered this by the affirmative some times ago, but I want to be sure."

Anyone who would still harbor the slightest doubt on step 3 is invited to jump on this occasion to make their point clearer. Brent? Bruce? Are you OK that the guy in Helsinki, a coffee addict (say), should not worry and that no matter what, his current (in Helsinki) need of caffein will be satisfied?

​Sure, but if history has taught us anything it's that what the law says and what is true are two entirely different things.​

​Getting the semantics and pronouns right is the first step, after that the personal identity theory could still be wrong but at least it's a theory and not gibberish.

But instead or arguing about whether "personal identity" is an identity (i.e. reflexive, transitive relation), which it isn't, why not just make up a new word for the concept that the Wman and the Mman are the "continuson" of the Hman but not of each other. And then explicate what is implicit in a the continuson relation. This is way science would proceed if we actually had a duplication machine. We'd make duplicates and we'd define continusation ostensively and then we'd study it's properties - instead of assuming things about computation and physics.
