In the real world, and in any world that doesn't have people duplicating machines, that question makes perfect sense and the personal pronouns in it cause no problems. And you're right, a ten year old can understand the question, even a five year old could. That's because the person who wrote "I am right here in Helsinki right now" has one and only one successor in the future and thus there is a unique answer to the question. However if people duplicating machines are introduced, as is done in the thought experiment, then the person who wrote "I am right here in Helsinki right now" does *NOT* have a unique successor, and so the question does *NOT* have a unique answer, in fact it doesn't have an answer at all because due to the wording the "question" is not a question at all, it is gibberish. It takes more than a question mark to make a question. >> >> but for that to work after the thought experiment is all over you've got >> to tell us what the correct prediction turned out to be so we can see that >> the correct prediction was not made.

Unfortunately we don't know exactly (or even approximately) what the question was, not in a world that has 1p duplicating machines . It's like the Hitchhiker's Guide to the Galaxy where the ultimate answer was known to be 42 but nobody knew what the ultimate question was. > > About the 3p, or 3-1p view. > After all these years I still can't figure out the difference between the 3p view and the 3-1p view .
