Yes, not only would it feel like (your nice phrase) "the line of subjective
experience" continued there, it would in fact continue there. Were the
miraculously rescued instance of the guy of the typical frame of mind
he'd exclaim "Wow! What a close call! This time instead of the true-me
getting teleported and the false-me getting disintegrated, it happened
the other way around! Now I have to hunt down that varmit what
was teleported and work out the legal arrangements since there are
two of us."

In my conception of what a *person* is, the answer is no. They're
still the same person and would remain so for many years until enough
difference had accumulated to make them clearly different people
(much as in the same way you are not the four-year-old you once
The software analogy is perfect: people are like programs, and instances
are like, well, running instances. And if some hacker makes some small
change to Linux, it's still Linux. It is, that is, until so many hacks have
been made that it's really not Linux anymore.

I've always called that the horrid "Anticipation Dilemma". At one point
in 1986 I couldn't even code because of it: I'd pace the halls at work
trying to figure out exactly why I didn't have to anticipate with great
relish the dinner I'd had the night before!

though I certainly got sent a copy.)

I don't think so. It's just that *anticipation* cannot, so far as I know,
be put on an entirely consistent rational basis.
I will re-post the essay I wrote to the list in April. Let me know if
you don't get it.
