Yes, I was very relieved to have read portions of that book.
Very few people I knew---and they, only because I had talked
them into it---accepted the theory that you and I are espousing.

Oh yes it was; I think that it got even worse before it got better.
But even today, it may be that you have to come to an "Everything"
list, or other forum where the skeptical and well-read hang out.

Why are you so sure that there is a fact of the matter?

Insofar as facts are concerned, there is a lot of agreement that
you are the same person you were yesterday. I'm not sure why we
need to redefine what is normally meant.

Oh, well if you mean to be talking about mental states, then
I cannot disagree with anything you've said. But if we are
trying to talk about "people" or personhood, it's evident
that many mental states correspond to one person.

Well, if you've characterized his views correctly, then he's
not in agreement with you, me, and Derek Parfit. What might
be fun to explore is how desperate some people would have to
be in order to teleport (or perhaps how lucrative the
opportunity?). Also, I suppose that if you confided to them
that this was happening to them all the time thousands of
times per second, they'd still have some unfathomable reason
not to go near a teleporter.

Finally, if we had such devices, soon only the real old fogeys
and a few peculiar philosophers wouldn't make steady use of them.
