Yes, and I note that these are *precisely* identical instantiations. > This means that most of my > measure is now in the latter half of 2005, in the sense that if you pick an > observer moment at random out of all the observer moments which identify > themselves as being me, it is much more likely to be one of the copies on > the computer. What? And I thought that I had understood how the term "Observer Moment" is used on this list! :-( Is the following true, or isn't it: identical OMs are identified. That is, N identical instances (say, running on N identical mainframes) are thought of as *one* observer moment, because they are (1st person) indistinguishable. At least that is how *I* have been using the term. (They're also 3rd person indistinguishable, of course.) Bruno wrote, incidentally, "With comp the relative measure from one OM is based on all comp histories going through [those] states. We should not measure the OM by its finite description...", and so it's possible that he is agreeing with my usage of the term "Observer Moment"." Thanks for any clarification. > But what does this mean for my experience of life? Does it > mean that I am unlikely to experience 2006, being somehow > suspended in 2005? I would say "no". I would say that *you* must experience 2006 in your experiment, and in fact, in any universe where you live through 2006. If we say that there are 2006 AD versions of Stathis running anywhere in the multiverse, then it is by definition true that you get runtime in 2006 (or that you experience 2006). What a number of us have tried to do, perhaps mainly so that our ideas conform with our daily values of trying to stay alive, is to regard the *benefit* one receives from a certain amount of runtime as the measure of the OM. Hal has very satisfactorily described the idea that you get superior benefit if your pleasant, even-numbered-days are given twice the measure of your odd, unpleasant days. > More generally, if a person has N OM's available to him at time t1 and kN at > time t2, does this mean he is k times as likely to find himself experiencing > t2 as t1? To me "to find oneself at X,t" in spacetime means to make an observation that one is at position X at time t, or perhaps better, that one is alive at X,t, a very 1st person description. But then, that would tend to distinguish the experience at t2 from the experience at t1, and that is contrary to your hypothesis. By the definition I thought was in vogue here, "from inside" there is just one OM, even though it's manifested at a number of spacetime locations (the entity doesn't know the difference). On a 3rd person objective bird's-eye view the greater number of instances do have, of course, a greater measure than does a single instance. So how does this translate to 1st person? I'd suggest that one's 1st person experience---though not memorably different---is "richer" and "fuller", and of more benefit to one! :-) Admittedly, this sounds like nonsense if one believes that one's memories capture all of one's experience. > I suggest that this is not the right way to look at it.

Yes, but appearances can be deceiving! And it won't be the first time that a patient is incorrect about which of two time intervals actually provided him the greater benefit. > The only significance of the fact that there are "more" OM's at > t2 [and I take it to mean that, using the terms as I do, the > OM at t2 has greater measure than the OM at t1] is that the > person can expect a greater variety of possible experiences at > t2 if the OM's are all distinct. Again, to me, if the experiences are distinct, then it's not the same OM. Lee
