Then please tell me what "FPI" is saying that "nobody knows what
they will see or do next" does not.
Indeed, you need to assume comp, understand that it makes your body
duplicable (as you already did), and then the FPI is the fact that
when a machine is duplicated, in w and m, say, it cannot predict the
first person result (which by comp must be either w or m, with the
step 3 protocol: it is what will be written in each copy-diary) in
advance. By the definition of the notion of first person, this is
simple to verify, by kids as Kim mentioned.
The FPI makes sense only through the notion of self-duplication, or
multi-self-reconstitution (be it by the quantum wave superposition, as
implicit in Everett, or in mechanical brain copies, assuming the
substitution level is correct, or in the tiny sigma_1 part of
arithmetic)

I know but it's not my fault, I was sick on the day my first grade
English teacher explained the difference.

I would say Hi pleased to meet you because I, the H-John Clark, is
not the HWWMWMMMW-John Clark because that guy has experienced things
the H-John Clark has not. However the situation is asymmetrical, the
HWWMWMMMW-John Clark is the H-John Clark because that fellow
remembers being the H-John Clark. The reason that in matters of
personal identity the "is the" relation does not have the
commutative property is that the past/future relation does not have
it either.
You illustre what I was just saying: you talk to him, and listen only
to yourself H-John Clark. You don't listen and answer to the
question and remark made by the HWWMWMMMW-John Clark. You don't even
quote the paragraph with his remark.
He told you that in Helsinki he predicted that everything would be
symmetrical and determined, yet, he realized eventually that this was
wrong, that he was never able to predict the city behind the door
after reconstitution, and that now, he see what I meant by "first
person experience", and that he understood why comp makes it
impossible to be sure in advance what that first person experience
will be. Clearly, he, the HWWMWMMMW-John Clark man, survived the
experience, but the duplication involved makes impossible to determine
where. My question is: how will you explain to him that he is wrong,
as it should be if there is no FPI.
