Re: Many worlds theory of immortality
Nice try, Danny, but as usual what I thought was a simple and direct concept was completely missed, qat least in the beginning (see what I mean Lee?). The key issue was the comment that despite the fact that the people in his brain weren't real, that they could still be considered real in our universe. Your response deals with "those people are real in the sense that his brain is devoting processing power to creating the mental image of the individual, and everything related to this individual's personality", which supports an hypothesis that I shared with Lee privately - that people who are completely immersed in one particular communication style and iconography will default to that style when addressed with a different one, despite its complete inability to accurately express what needs to be communicated. As usual on this list, that communication style is biased heavily toward computer technology. So instead of a subjective vs objective argument, which is where Saibal's idea really falls (along with the one that Stathis dodged), the first concept out of the box from you is a qualitative defense of how real Nash's friends were because of the "processing power" his brain was devoting to creating them. Sounds like you're talking about a Pentium chip or something, never mind that the amount of power that his brain is using is irrelevent. If he hallucinated that he saw one obscure figure for a split second and never saw it again, that obscure figure would be no more real in "our universe" than his hallucinated friends were. However, you do finally get around to "Therefore the person is real to at least one first person perspective, but is not currently real to any third person perspective." which takes us right back to my original question to Saibal, which was how come he said that they *were* real in "our universe"? The key phrase being "our universe" which means the objective reality that we can all agree upon typically because of shared and agreed upon observations which would exclude subjective hallucinations. As usual, the basic, straight forward questions go unaddressed in favor of the usual banter, but that's par for the course here. I'm just playing through. "It is not impossible to conceive of future devices that could display thoughts on a screen, or even materialize the thought (for you Trekkies), making the person real even to the third person perspective."

To me, "brainstorming" just means any creative attempt to come up with new tentative speculations about solutions to a problem.

How else would he have come up with them, logical deductions from a set of axioms whose truth was totally certain? Divine revelation? You're the one that >called the ideas discussed here often as "half-formed". Yes, and I would define any idea that has not been made into a fully-worked out, complete theory as "half-formed".

You're assuming that Einstein came up with those ideas through brainstorming. You're the one that called the ideas discussed here often as "half-formed".

"Rambling speculations about half-formed ideas that probably won't >pan out to anything" is a good description of talking to hear ones-self talk. Sometimes, but it's also a good description of brainstorming ideas that aren't fully developed yet. If I had speculated in 1910 that perhaps the force of gravity could be explained in terms of objects taking the shortest path in curved space, but didn't have a full mathematical theory that fleshed out this germ of an idea (and also didn't yet see that the longest path through curved spacetime would be better than the shortest path through curved space), then this would be a "halfed-formed idea that probably wouldn't pan out to anything", but it might still be useful to discuss it with others who found this germ of an idea promising and wanted to develop it further. That's how I see the purpose of this list, a combination of brainstorming ideas about the "everything exists" idea and then criticizing, fleshing out or disposing of these ideas. So certainly criticism of specific ideas that don't make sense is valuable, but I don't think it's helpful to accuse anyone who comes up with an idea that doesn't work out of just wanting to hear themselves talk. If it's not going to pan out anyway, then it's pretty meaningless.

Actually, if a person believes they are perceiving a parallel reality a number of questions must be asked first. 1. Is this supposed to be a branch off of our world or is it a world that is distantly related or not related at all? 2. Having identified what type of world, then as much information should be gathered about it as possible to create a database that can be analyzed for evidence from which determinations can be made as to whether the person really is perceiving a parallel world of some kind of just has mental issues. The easiest case would be one where the person in question claims to have awareness of some other world with different technology. If they can't describe it any more than on a superficial level, then the probability is high that its all just some kind of dellusion. However, if they can, especially to the point of it being reproduced here, and especially if they can describe a number of devices or technologies which don't exist here but can be produced here, then I would say that it warrants a much closer look. The greater the detail a person can obtain from their perceptions, the easier it is to map out a description of the other world. If the detail is great enough, then it might be possible to at least decide that even if it can't be conclusive as to whether or not the information is derived from parallel world perception or a highly detailed hallucination, a better understanding can be had of what it is the person is experiencing. For example, 30 years ago a person walks into a psychiatrist's office and talks about how he keeps having visions of the world and it's all weird. After a number of sessions, the psychiatrist learns that the patient has perceptions of the world where the Soviet Union doesn't exist anymore, there's a major conflict in the Mid East with Iraq, and the World Trade Center doesn't exist anymore. Not enough detail. Could be just wild imagination based on obvious scenarios. However, if the patient starts naming names like George W. Bush, Osama bin Laden, Putin, etc. then the psychiatrist can begin to construct that database and see if any of these people really exist. The more data, the better. Eventually extrapolations can be made as to whether the patient is seeing the future of the world that they're in or perhaps a parallel world. This is an oversimplification of how the process really works, but one that points a direction for how these kinds of questions are actually investigated. BTW, 30 years ago, almost all science fiction written about the near future, had the Soviet Union still in existence. Anyone saying that they had perceptions of a future where it no loner existed, without the use of nuclear war, would truely have been seen as crazy. Yet, they would have been correct. >However, this response is completely wrong if MWI is > correct.

Some people are offended by this assertion, and believe there is some special ingredient or mysterious process involved in cognition, which is perhaps forever beyond scientific scrutiny. We could call this folk dualism and folk vitalism, and it is very common in the community. Of course, it's nonsense. Having clarified that, I still think there is a real issue when considering consciousness and the 1st person/ 3rd person distinction. The problem is that it is possible, in theory, to collect, record and communicate information about any aspect of the physical universe *except* one's conscious experience. A person who is blind from birth might learn everything about light, how the eye works, how the brain processes sensory data from the optic nerve, and so on, but still have *no idea* of what it actually feels like to see. I don't believe there is some "deeper explanation" for why we have conscious experiences; manifestly, it is something that happens when certain electrochemical reactions occur in our brain, just as travelling down the road at 60 km/h is something that happens when controlled explosions occur in the cylinders of a car's engine. But this does not mean that the unique, private nature of conscious experience should be ignored or denied. --Stathis Papaioannou _ Dont just search. Find.

Re: many worlds theory of immortality
Le 13-mai-05, à 05:39, Lee Corbin a écrit : Brent writes I think that an observer must be physically instantiated - that seems well supported empirically. As it is used a "observer moment" seems to mean a unit of subjective experience. That there is an "observer", i.e. something with continuity over many such subjective experiences, must be an inference or a construct within the theory. Personally, I would agree. But many here contend that abstract patterns---mathematical stings, really---can do *so* much cross- referencing and quoting of each other that a form of paste obtains that wields them in to something capable of having experiences. But a familiar abstract object, namely the real numbers between zero and one, evidently already does all of that (considering the decimal or binary expressions), and so I'm not sure what remains for the more abstruse inhabitants of Platonia to do. Such critics can be addressed to any "block-universe" view of physics, not just mathematical platonia. Yes, that's the simplest explanation! We have to suppose that physical objects continue to encode previously gained information in the default case. I don't know that "we have to". I've know idealists who suppose that our memories are part of our immaterial spirits. But they have a hard time explaining the limitations of memory. Such idealists have a hard time being credible at all, if you ask me. But what John was perhaps saying---and what I would certainly claim along with all the adherents of "observer-moments", I think---is that any particular version of you at any particular moment is not conscious of the facts encoded in all your memories. Hence the idea that an observer-moment is the net intersection across the multiverse and across other planetary systems of a particular sense-perception experience of a particular person. But if, for each subjective experience, there is no way to uniquely associate it with a sequence of subjective experiences, i.e. every such experience has many predecessors and successors, then I don't see how such sequences can constitute a particular person(s). I agree. That is, freed of memory, just how are all those subjective moments linked in a particular ordered sequence? I also agree with your statement, when *persons* (as you write) are being considered. I'll admit that there is something---but not very much---associated with a person that has nothing to do with the person's memories. It seems in these discussions that the existence of such sequences corresponding to a particular person, an "observer", is taken for granted. It is a natural model given that observers are physical things - but it is problematic if physics is thrown out and you start from nothing but "observer moments". Well said. A natural model does give us that observers are physical things, or at least *necessarily* instantiated in physical things. And I agree that starting from nothing but observer-moments won't take us any further than it took William James http://plato.stanford.edu/entries/james/ I can't blame the ancients and moderns up to the 19th century for being dualists. It seemed utterly impossible that mere atoms in motion could give rise to such as we. But the painful ---and painstaking---defeat of vitalism achieved finally in the 20th century leaves it the simplest hypothesis by far to say that we are machines. Our "souls" and we arise by natural means, just as do streams and mountains. Look at my recent posts to the FOR-LIST, which I have cc-send to the everything-list just two minutes ago. I agree the abandon of vitalism is a progress. And it is true that natural science has explained feature like self-reproduction, animal motion, energy transformation (sun -> living matter) and so one. But it is just erroneous to conclude that the mind-body problem has been solved. And then if we are really "digital machine", I offer a case that materialism will be abandoned from purely rational consideration. Matter? A lasting aristotelian superstition ... Observer-moments seems to arise simply from observers, Except that nobody has ever succeed in explaining how the 1-person observer moment can arise from any 3-person description of an observer. And myself and independently Maudlin has made a strong case why, with the comp hyp it is just impossible to make such a link. Reference can be found here: http://iridia.ulb.ac.be/~marchal/lillethesis/these/ node79.html#SECTION00130 and observers arise simply from highly intelligent mammals (or aliens) who can think about their own thinking. Unless you want (which is probably a good idea) to regard even photographic plates and other matter upon which impressions can be made as *observers*. Lee Bruno http://iridia.ulb.ac.be/~marchal/

In considering what it takes to be an observer, I find it useful to think about robots. What would I have to design into a robot in order that it be an observer - and not just a recorder? I think the essential elements are having a goal, the ability to act, and the ability to learn from experience. At a rudimentary level I'd say the Mars rovers qualify as observers. Brent Meeker

Jesse --- Begin Message --- Dear Stathis: Your interpretation of my "anger" says more about you than me. I didn't flame you or call you or mentally ill people names. My only point is that if you want to seriously investigate complex concepts scientifically, then it helps to have the most accurate methods available. Even considering that a person with an illness that prevents them from having temporal awareness (or knowing the difference between one moment to the next) could have some significance on understanding the nature of time is folly for the simple reason it is time that being effected in their case, its their brain's ability to percieve it. Their condition is having know objective effect on time at all. It would be diiferent if you put such a person in a room with a bunch of measuring devices and then detected that temporal anomalies were recorded of some kind, but that doesn't happen. Their perceptions are completely subjective, ie inconsequential, unless you're studying their condition. But, if the! purpose of your research is time, like mine is, data based on the perceptions of such an individual is useless, unless, like I suggested, you really just want to jabber about this and that idea, with no criteria for trying to seriously understand the subject at hand.

Re: Many worlds theory of immortality
I agree with Stathis' answer to Jeanne. Another one which looks a little bit incompatible with the one by Stathis would be: if QM is correct no information can travel from one universe to another. So such an hallucination can only be such a coincidence or a triviality (whatever I think, there is a universe where ... but that lead to the measure problem, and the fact that we cannot really *stay* in a "Harry Potter" universe). But what if QM is almost correct but *slightly* incorrect? Then, as Weinberg has shown in the case where the SWE (Schroedinger Wave Equation) is changed to be slightly non linear, it becomes possible to travel or communicate between universes. It is quite speculative because it makes also the second principle of thermodynamic wrong in a large part of the multiverse, but it is not inconsistent. I vaguely remember having read that some cosmologist believes that they have some case for the slight non linearity of the SWE. So ... And what happens with comp? I would just say: open problem. Better staying agnostic until more information and results are provided. Of course the real problem of Jeanne's question is that we cannot give much 3-person weight to "rare" first person narration. We can give 1-weight, but it's probably better to stay mute on this in a 3-list.

Re: Many worlds theory of immortality
Dear Stathis: Your interpretation of my "anger" says more about you than me. I didn't flame you or call you or mentally ill people names. My only point is that if you want to seriously investigate complex concepts scientifically, then it helps to have the most accurate methods available. Even considering that a person with an illness that prevents them from having temporal awareness (or knowing the difference between one moment to the next) could have some significance on understanding the nature of time is folly for the simple reason it is time that being effected in their case, its their brain's ability to percieve it. Their condition is having know objective effect on time at all. It would be diiferent if you put such a person in a room with a bunch of measuring devices and then detected that temporal anomalies were recorded of some kind, but that doesn't happen. Their perceptions are completely subjective, ie inconsequential, unless you're studying their condition. But, if the purpose of your research is time, like mine is, data based on the perceptions of such an individual is useless, unless, like I suggested, you really just want to jabber about this and that idea, with no criteria for trying to seriously understand the subject at hand. If these comments upset so much that you think I'm angry, that's on you.

Re: Many worlds theory of immortality
Dear Stathis, This ties in with the subject header of this series of posts, which is a rare occurence: Many Wolrds Immortality, according to which there will be some branch of the multiverse in which I hit enough crows and pigeons on the way down to form a lifesaving mushy matress (mattress?), is a special case of a 'many-worlds-absurdity theorem' in which in some branch of the multiverse I will look down and find my leg be a peg and my ass a giraffe. But these will only happen if there are infinitely many, rather than just many, worlds. If you believe in some finite or countable discrete structure underlying physics, then you could ultimately identify definite events in which the universe branches off into a finite number of different cases (which would grow exponentially in time, but would after any given time be finite). -Chris Collins - Original Message - From: "Stathis Papaioannou" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Cc: Sent: Thursday, May 12, 2005 2:25 PM Subject: Re: Many worlds theory of immortality > The obvious and sensible-sounding response to Jeanne's question whether it > may be possible to access other universes through dreams or hallucinations > is that it is not really any more credible than speculation that people can > contact the dead, or have been kidnapped by aliens, or any other of the > millions of weird things that so many seem to believe despite the total lack > of supporting evidence.

Re: [Fwd: Re: Many worlds theory of immortality]
I read "Why Occam's Razor" tonight after posting my last response (despite having a Federal court brief begging for attention). I didn't have time to wade through the technical parts very thoroughly, but in general I found it a very good summary of many of the topics we have been frequently discussing on this list. I also re-read (skimmed) Nick Bostrom's "are you living in a simulation" paper tonight, and it occurs to me if you add his argument to MWI, you get the inevitable conclusion that we are simulated, which I guess is actually a similar concept to Marchal (though Marchal goes much further in attempting to derive QM, etc. from this). One difference being that Marchal argues the UTM does not need to actually exist physically, but as you state in your paper if I read/remember correctly, the UTM would exist both as mathematical and physical structure. This then leads back to questions about the differences between the mathematical and physical structure; if any. With consideration that any given area of the multiverse is inevitably and eternally being simulated by another area, I thereby come full circle and see what Marchal is saying - there is no need to even consider what we refer to as the physical. I wonder if, considering Godel, we are forever doomed to walk around in circles like this Danny Mayes many seem to bend over backwards to say you do not actually have to have the UTM exist physically Russell Standish wrote: On Thu, May 12, 2005 at 12:40:10AM -0400, danny mayes wrote: Russell, When I stated in the original reply that pulling information out of other worlds in the MWI context was prohibited by physics, I was referring to information about those universes.

Take an example Multiverse that has one spin 1/2 particle in it. Clearly, it consists of two worlds, one which has spin +1/2\hbar, the other with spin -1/2\hbar in the z-direction. However, this Multiverse also has another two worlds in it, one with spin +1/2\hbar and one with -1/2\hbar, however this time in the x-direction. And so on. All these worlds exist. By choosing to measure the particle in the x-direction, I get information from both of the "+1/2-" and "-1/2 in the z-direction" worlds, hence there is a form of information flow between worlds. Nevertheless, there is, as you say, no information flow between decohered worlds. Also, I'm interested in your TIME hypothesis. Could you refer me to a source for information, or summarize for me?

Would that be productive in the scientific sense? Communication between worlds takes place within the confines of quantum superposition. Setting up the superposed states is what I mean by "prepared".

Every so often I have to remember that I studied the clarinet as a boy; but that doesn't ever seem to affect me except on the very rare occasions that something reminds me of it. So at any given moment "I" am that which is perceiving thus- and-such, and is having a certain reaction to it.

We have to suppose that physical objects continue to encode previously gained information in the default case. But what John was perhaps saying---and what I would certainly claim along with all the adherents of "observer-moments", I think---is that any particular version of you at any particular moment is not conscious of the facts encoded in all your memories. Hence the idea that an observer-moment is the net intersection across the multiverse and across other planetary systems of a particular sense-perception experience of a particular person. Lee

I agree there is reason to postulate a transcedent observer; I'm content with a physical observer. That's one of the things that bothers me about "observer moments", but I think it's just English grammar that pushes us to have a subject. If you're going to reconstruct physics from discrete subjective experiences you need to be able to collect and order experiences according from viewpoint - which corresponds to an "observer" - and according to intersubjective agreement among observers - which corresponds to the physical world. But just because the subjective observer is a construct, doesn't justify the pejorative "pretend". I think I have considerable evidence for information, such as what I ate for breakfast, being persistently encoded in my brain. No only the fact that I can recall such information, but also that my ability to do so diminishes with time and may be lost due to disease or injury. Brent Meeker

The 2nd part startled me a bit, the reference to 'objective science' may suppose that the 'time' etc. experiences would be common and identical to all conscious beings. First off: objective science is a model, inherited evolutionarily from learning similar stuff from reports of those who earlier constructed them as their 1st pers. explanations. Secondly: even in this case every 'conscious being' makes up his own 1st person mindstuff from such reports and not two may be completely identical. Not even in clones. Machines: yes. We can try to share it, but the result will be personnified by the acceptor into 'his' 1st pers.mindcontent. Unless we introduce some "objective knowledge" to ourselves, exempt from the minds interpretation. That is what I would label 'truly objective'.

Does e.g.infinite mean very much or very long? (or a small circle? G. Cantor's problem...). I think 'eternal' is atemporal, cannot be measured 'in time', or expressed by a timespan, so why not consider it really as timeless: when it starts it immediately also ends instantaneously.

I agree with you Stathis. That's why I think MWI, QTI and COMPI lead to the Relative SSA, and relative immortality. The SSA you mention is the Absolute SSA which does not make sense, imo.

OK, let me take what you just said there, "conscious despite a disability which impairs their perception of time". A person can be conscious and have any number of disabilities that impair their perception of reality. Doesn't mean that their perception is accurate, valid, or even mildly interesting. The word "impair" should have been a clue. >Your post raises an interesting question in that you seem > to assume that normally functioning human minds have a correct > model of reality, as opposed to the "broken" minds of the mentally > ill. This is really very far from the truth. If the mentally ill had a correct perception of reality, they wouldn't be mentally ill. Hello? Simultaneously, not all sane people have a "correct model of reality" (whatever that means) but they usually know what they're doing on a basic level and function without taking medication to keep them tuned into reality and not the psycho channel. It doesn't mean that they can't be motivated by wrong ideas or misconceptions or even manipulated by somebody smater or with political power, but we're talking apples and oranges now. > Human brains evolved > in a specific environment, often identified as the African > savannah, so the model of the world constructed by the human mind > need only match "reality" to the extent that this promoted survival > in that environment. And if their perception of that reality environment hadn't been correct, they wouldn't have survived. Simultaneously, other creatures, in that same environment, developed other ways other perceiving it. The point you're missing is that the environment is the same. If I take an array of sophisticated measuring and recording devices into that environment, I should be able to detect all of the aspects that most of the non-insect creatures do, and in some cases, a lot of the insect perceptions. However, if I introduce a paranoid schizophrenic into the equation, I will probably not detect the hallucinations that he will see, though I may be able to identify possible external causes. >As a result, we humans are only able to > directly perceive and grasp a tiny, tiny slice of physical reality. Which doesn't make the hallucinations of the mentally ill or those with cognitive disabilities, any more valid. > Furthermore, although we are proud of our thinking abilities, the > theories about physical reality that humans have come up with over > the centuries have in general been ridiculously bad. I think part of the problem here is the use of the term "reality" when something else would be better. Since you failed to give any examples of what you meant by "theories about physical reality" I will assume that you mean the matters dealing with the nature of the Earth and its place in the solar system, etc. If not, please be specific. In any case, much of those errors in perception had to do with physical limitations in the ability to conduct accurate observations, further crippled by various philosophical dogma. >I have spent the last ten years treating patients with schizophrenia, and I can > assure you that however bizarre the delusional beliefs these people > come up with, there are multiple historical examples of apparently > "sane" people holding even more bizarre beliefs, and often > insisting on pain of death or torture that everyone else agree with > them.

Re: Many worlds theory of immortality
I vaguely recollect the phenomenon you mention, if I am thinking of the same thing. The problem is that when something "goes wrong", either in a brain or in another machine, in the vast majority of cases it will result in some sort of dysfunction. If you took to your computer with a hammer, there is a *tiny* chance that you will somehow improve it, or give it some new ability, but most likely you will damage it. Having said that, the process of evolution works in exactly this way: random errors occur, and that tiny proportion which results in survival advantage is selected for. I have heard of a much older theory about schizophrenia, that the kind of weird/lateral thinking that occurs in subclinical cases (who are perhaps carriers of the SZ gene or genes) may be responsible for the great intellectual innovations in human history, which is why this devastating disease has not died out. --Stathis Papaioannou From: "Jeanne Houston" <[EMAIL PROTECTED]> To: "Stathis Papaioannou" <[EMAIL PROTECTED]>,<[EMAIL PROTECTED]> CC: <[EMAIL PROTECTED]>, Subject: Re: Many worlds theory of immortality Date: Tue, 10 May 2005 07:19:01 -0400 I once read an article in, I believe, Time Magazine, about the relatively new field of "neurotheology" which investigates what goes on in the brain during ecstatic states, etc. One suggestion that intrigued me was that it may be possible that in such a state, and I believe that schizophrenics were also mentioned, that the brain is malfunctioning in such a way as to allow it to perceive states of reality other than that which the normal brain would perceive.

Hi Stathis, I also believe that the observer moment is fundamental, but I don't think there is anything wrong with "I think therefore I am" as long as this statement is taken as a definition of "being" rather than as an explanation: Look at it as "I think, this means 'I am.'

The way I would say it is that you can only experience worlds where you are conscious. Being alive is not enough. But really, this is a tautology: you can only be conscious in worlds where you are conscious. It sheds exactly zero light on any interesting questions IMO. > And to continue, I find it very > difficult to imagine what could mean being unconscious forever (what you > suggest to be likely). Yet you have already been unconscious forever, before your birth (if we pretend/assume that the universe is infinite in both time directions). Can you imagine that?

If it is guaranteed that > somewhere in the multiverse there will be a million year old Hal > observer-moment, doesn't that mean that you are guaranteed to experience > life as a million year old? I don't think there are any guarantees in life! I don't see a well defined meaning about anything I am guaranteed to experience. I am influenced by Wei Dai's approach to the fundamental problem of what our expectations should be in the multiverse. He focused not on knowledge and belief, but on action. That is, he did not ask what we expect, he asked what we should do. How should we behave? What are the optimal and rational actions to take in any given circumstances? These questions are the domain of a field which, like game theory, is a cross between mathematics, philosophy and economics: decision theory. Classical decision theory is uninformed by the AUP, but it does include similar concepts. You consider that you inhabit one of a virtually infinite number of possible worlds, which in this theory are not real but rather represent your uncertainty about your situtation. For example, in one possible world Bigfoot has sneaked up behind you but you don't know it, and in other worlds he's not there. You then use this world concept to set up a probability distribution, and make your decision based on optimal expected outcome over all possible worlds. Incorporating the multiverse can be done in a couple of ways. I think Wei proposed just to add the entire multiverse as among the possible worlds. Maybe we live in a multiverse, maybe we don't. The hard part is then, supposing that we do, how do we rank the expected outcomes of our actions? Each action affects the multiverse in a complex way, being beneficial in some branches and harmful in others. How do we weight the different branches? Wei proposed to treat that weighting as an arbitrary part of the user's utility function; in effect, making it a matter of taste and personal preference how to weight the multiverse branches. I would aim to get a little more guidance from the theory than that. I would first try to incorporate the measure of the various branches which my actions influence, and pay more attention to the branches with higher measure. Then, I think I would pay more attention to the effects in those branches on observers (or observer-moments) which are relatively similar to me. However, that does not mean I would ignore the effects of my actions on high-measure branches where there are no observers similar to me (i.e. branches where I have died). I might still take measures such as buying life insurance for my children, because I care about their welfare even in branches where I don't exist. Similarly, if I were a philanthropist, I might take care to donate my estate to good causes if I die. These considerations suggest to me an optimal course of action in a multiverse, or even in a world where we are not sure if we live in a single universe or a multiverse, which is arguably the situation we all face. It rejects the simplicity of the RSSA and QTI by recognizing that our actions influence even multiverse branches where we die, and taking into consideration the effects of what we do on such worlds. There is still an element of personal preference in terms of how much we care about observers who are very similar to ourselves vs those who are more different, which gives room for various philosphical views along these lines. And in terms of your question, I would not act as though I expected to be guaranteed a very long life span, because the measure of that universe is so low compared to others where I don't survive.

I'm not one to shy away from what others would perceive to be "unbridled speculation," however there are a few fundamental problems with the idea set forth by Jeanne. First, to the best that I understand, there is no evidence that we will ever be able to access the information of the parallel outcomes (worlds) in question. We can access the processing power of the other worlds, but the laws of physics seem to prevent our pulling information from another "world" into our world given the collapse that happens at the end of a computation (when we get our result from a quantum computer). So the idea seems to be prohibited by the laws of physics. And lets not even get into the proof problem. It's sort of like UFO's. Is it easier to believe that someone is crazy/seeing things/misinterpreting stimuli, or that they really are seeing other worlds/aliens? Spectacular claims require spectacular proof, and I don't see how this idea presents the prospect of any proof. Perhaps, if someone could in a statistically significant way predict future events or the location of hidden items, like remote viewing, could provide evidence, but there would still have to be some way to establish the link between that phenomena and other worlds.

You just made my point for me. There's a difference between hallucination and objective reality. People with mental illness have a problem with objective reality. Whether they are conscious or not is irrelevent because even if they are conscious, they still can't observe and process objective reality accurately. People with temporal perception disorders, etc. are not what we should be basing our concepts of time in physical objective reality, on. If you do, you really aren't interested in discovering anything new about objective reality. You really just want to "hear" yourself talk, because nothing else worthwhile is coming from it. Chatter.

Re: Many worlds theory of immortality
I once read an article in, I believe, Time Magazine, about the relatively new field of "neurotheology" which investigates what goes on in the brain during ecstatic states, etc. One suggestion that intrigued me was that it may be possible that in such a state, and I believe that schizophrenics were also mentioned, that the brain is malfunctioning in such a way as to allow it to perceive states of reality other than that which the normal brain would perceive.

Yes, Tegmark calls this the "Level I" concept of a multiverse. It's not so much that the multiverse is truly infinite, it is enough if our own mundane universe that we see around us is spatially infinite, as predicted by inflation theory.

While it is likely that some version of you will end up in a hellishly random universe as a result of QTI, you probably won't stay there very long, since if your particular brain pattern arose randomly, it will probably become disrupted randomly as well.

Re: Many worlds theory of immortality
Russell, To be fair, I should elaborate on my earlier post about amnesics and psychotics. If I consider the actual cases I have seen, arguably they do have *some* sense of the passage of time. Taking the first example, people with severe Korsakoff Syndrome (due to chronic alcohol abuse) appear to be completely incapable of laying down new memories. If you enter their room to perform some uncomfortable medical procedure and they become annoyed with you, all you have to do is step outside for a moment, then step back inside, and they are all smiles again, so you can have another go at the procedure, and repeat this as many times as you want. While you are actually in their sight, however, they do recognise that you are the same person from moment to moment, and they do make the connection between the needle you are sticking into them and the subsequent pain, causing them to become annoyed at you. So they do have a sense of time, even if only for a few seconds. The second example, the disorganised schizophrenic, is somewhat more complex. There is a continuum from mild to extreme disorganisation, and at the extreme end, it can be very difficult to get any sense of what the person is thinking, although it is quite easy to get a sense of what they are feeling and it would be very difficult to maintain a belief that they are not actually conscious (you really have to see this for yourself to understand it). Usually, even the most unwell of these patients give some indirect indication that they maintain some sense of time. For example, if you hold out a glass of water, they will reach for it and drink from it, which suggests that they may have a theory about the future, and how they might influence it to their advantage. Occasionally, however - and I have to confess I have not actually tried the experiment - there are patients who seem incapable of even as simple (one could say near-reflexive) a task as grabbing a glass of water. With treatment, almost all these people improve, and it is interesting to ask them what was happening during these periods. Firstly, it is interesting that they actually have any recollection. It is as if the CPU was defective, but the data was still written to the hard drive, to be analysed later. They might explain that everything seemed fragmented, so that although they could see and hear things, the visual stimuli did not form recognisable objects and the auditory stimuli did not form recognisable words or other sounds. Furthermore, the various perceptual data seemed to run into each other spatially, so that it was not possible to distinguish background from foreground, significant from insignificant. Catatonic patients, on the other hand, may (later, when better) describe a state of total inertia, being stuck in the present moment, unable to move either physically or mentally, unable to even imagine a possibility of change from the present state, aware of everything going on around them as a kind of extended simultaneity. --Stathis Papaioannou On Mon, May 09, 2005 at 11:02:18PM +1000, Stathis Papaioannou wrote: > Dear aet.radal ssg, > > I think you missed my point about the amnesic and psychotic patients, which > is not that they are clear thinkers, but that they are conscious despite a > disability which impairs their perception of time. Your post raises an ... As I said before, I think this is a valuable contribution, but not something I know how to deal with at this point in time. Presently, these psychotic patients account for only a fraction of conscious observers (assuming they are conscious as you say they are). Quantum Mechanics only requires that most observers have their own time like domain, not that all of them do. I'm still not convinced that TIME isn't a necessary property of observerhood, as opposed to a likely contingent one, but there the debate stagnates, as I'm not an expert in psychiatry. I did want to throw one more po thought. Even though standard QM is based on continuous time, nowhere does TIME require time to be experienced continuously. It could just as easily be the Cantor set, say. Might not the time experienced by these psychotic people be a fractal set like that, or are you saying they have absolutely no sense of time at all?

In most cases you will then find that your immortal experience is of a purely random universe, which is likely a good definition of "hell". Jonathan Colvin

Re: Many worlds theory of immortality
Dear Chris, I happen to be a believer in the observer-moment as fundamental, and the only thing one can be sure of from the first person perspective. "I think, therefore I am" is taking it too far in deducing the existence of an observer; "I think, therefore there is a thought" is all that I can be absolutely certain of. Having said that, however, I don't actually believe that my thoughts are all independent of each other. The simplest and most likely explanation is that my thoughts are generated by my brain in the usual manner. The point is that this is not *logically* necessary, and if we are talking about consciousness persisting over billions or trillions of years, the "usual manner" won't be the most practical. Your second point is something I have often thought about. I am pretty sure that dogs experience observer-moments, but I am not sure that worms do; if they do, then maybe our present day computers are not far off from being conscious, unless there is some non-computational aspect of biological nervous systems that has so far remained obscure. I would class viruses as being on a par with inanimate objects as far as conscious experience is concerned, but who knows, maybe inanimate objects have a rich but utterly alien subjective life from which we are as completely excluded as if we were in separate universes. --Stathis Papaioannou Dear Stathis, This was an interesting post. You're right in that, until quite recently, we've understood the world only as well as we've needed to, in order to survive. But if you believe, as some people on this list do, that instantaneous 'observer moments' are the only fundamentally real objects in the universe, (and that the reasoning, 'I think therefore I am' runs primarily in that direction) then it is the logical struture of our thopughts that is at each moment retrospectively generating a history in which there evolved a creature intelligient enough to think them. From this perspective, there is then a difference when someone becomes too mentally disfunctional to survive by themselves; then their incoherent patterns of thought will have to go one better and retrospectively generate a history in which a successful species evolved, of which they are a defective variant (we might all belong in this category, and keep each other sane..) But really, here we have to be more specific about what constitutes an observer moment, and what does not. Do dogs, worms, viruses have observer moments, or did they just coevolve in the history we might claim to have created by thinking and being? I would suggest that they are as real as we are, and that human consciousness is only distinguished from the animal sort in matters of quantity and capacity, and believe that the sorts of thoughts thatcan be taken as the fundamental objects of the universe are those that appear in the context of an organism successful response to its surrounding environment. This could be seen as a compromise between taking thoughts as fundamental, and a more old-fashioned 'physicalist' perspective, but I would see it more as observer moments being associated with the observer and his/her/its environment. After all, the distinction between these is pretty vague: Does the apple I just ate count as me or my environment? What if I made myself sick? What if I cut off my appendage?

Your post raises an ... As I said before, I think this is a valuable contribution, but not something I know how to deal with at this point in time. Presently, these psychotic patients account for only a fraction of conscious observers (assuming they are conscious as you say they are). Quantum Mechanics only requires that most observers have their own time like domain, not that all of them do. I'm still not convinced that TIME isn't a necessary property of observerhood, as opposed to a likely contingent one, but there the debate stagnates, as I'm not an expert in psychiatry. I did want to throw one more po thought. Even though standard QM is based on continuous time, nowhere does TIME require time to be experienced continuously. It could just as easily be the Cantor set, say. Might not the time experienced by these psychotic people be a fractal set like that, or are you saying they have absolutely no sense of time at all?

Dear aet.radal ssg, I think you missed my point about the amnesic and psychotic patients, which is not that they are clear thinkers, but that they are conscious despite a disability which impairs their perception of time.

Do you "feel" like you are that age now? 10 years ago there were things that you had no knowledge of, that you do now. Just as you are made up of different atoms, etc now, you also have different experiences, and expanded knowledge base, etc. In other words, you are not the same person and you really don't "feel" like you're the same person. However, you are the sentient human entity that was born however many years ago and have accumulated the sum total of knowledge, experience, etc, that you have so far. That said, the observer moments that you have are connected because they're your observer moments and are compared against your base of past experience, etc. They are casually connected if they are moments that are observed in the first place. You're at bat in a ball game and the pitcher throws the ball and you swing and miss and the ball hits you. Each moment in that sequence is related casually and temporally with the other. The moments can be recalled separately but there is still a casual link. >and on > thought experiments where continuity of identity persists despite > disruption of the physical and causal link between the earlier and > the later set of observer moments (teleportation etc.). We don't have teleportation yet, especially the demat/remat type (which IMHO is impossible), so I don't see how invoking that is reasonable. Taking a chance to interpret your intent otherwise, I would say that disruption of so-called physical and casual links can happen anytime consciousness is lost, ie sleep, blow to the head, anesthesia, etc. It doesn't support your argument about observer moments being separate in any case. > > Another question: what are the implications for the TIME postulate > raised by certain mental illnesses, such as cerebral lesions > leading to total loss of short term memory, so that each observer > moment does indeed seem to be unrelated to the previous ones from > the patient's point of view?

No more capable of accurate determination of what is casual, temporal or anything else than a computer is capable of accurate functioning after its been damaged by a virus or some other disruptive event. I had a pocket calculator get wet once and all I could get out of it when I attempted calculations were wrong numbers and sometimes abstract partial digital displays. I no more considered what I was getting from the calculator as valid than I do the perceptions of a patient with "formal thought disorder". The point is their perceptions are wrong, not just different, they're inaccurate and can be demonstrated to be so.

The difficulty would be in establishing whether a sufficiently mentally ill person is in fact conscious. Since consciousness is a 1st person phenomenon, we only infer consciousness in others by means of a mental model of the mind based on our own consciousness. When the other individual departs too much from our mental model, we would be tempted to discount the other person as being conscious. Certainly, I would regard a reasonably ordered version of TIME as a prerequisite for consciousness, but that includes things like Cantor sets just as much as more conventional notions of continuous time.

Re: Many worlds theory of immortality
I would add another point with regard to observer-moments and continuity: probably there is no unique "next" or "previous" relationship among observer-moments. The case of non-unique "next" observer-moments is uncontroversial, as it relates to the universe splitting predicted by the MWI or the analogous effect in more general multiverse theories. Non-unique "previous" observer-moments can probably happen as well due to the finite precision of memory. Any time information is forgotten we would have mental states merge. This requires a general multiverse theory, or at least a model of mental states that span MWI branches; the conventional MWI does not merge branches which have diverged through irreversible measurements. In this view, then, we can chain observer-moments together to form observer-paths, or more simply, observers. But the chains are non-unique; obervers can intersect (share observer-moments and then diverge), or even braid together in interesting ways. That means that there is no unique sense in which you are a particular observer, at any moment; rather, you can be thought of as any of the observers who share your current observer-moment.

Re: Many worlds theory of immortality
Reading your responses here, I don't think we have much to disagree on. Like you, I don't need a concrete universe, with concrete time etc. It was largely your thesis that convinced me of that. Perhaps you confuse me with Schmidhuber too much ! I wouldn't say that time is illusionary. Illusionary means that something either not real, or is not what it seems. I'd prefer to say that time (psychological) is an emergent property of the 1st person description. (Emergent wrt the 3rd person). If you want to know what I mean by emergence, please read my paper "On complexity and emergence" - its fairly short. By way of analogy, I remember from high school physics that centrifugal force was called "imaginary". At the time I thought this was bizarre - the force is real enough, its really a question of reference frames. In the rotating reference frame, centrifugal force is real, balancing centripetal force to make the orbiting body motionless. In the non-rotating reference frame the centripetal force causes the body to orbit (constant acceleration). Emergence has something to do with reference frames... Of course psychological time differs from coordinate time, which is a 3rd person concept, and quite possibly emergent as well (wrt a deeper description of reality) The correlation of psychological and coordinate time is interesting, and I don't feel I understand it fully, but is probably not worth delving into in this email.

OK. As you know I take the relationship into account. With my TIME postulate, I say that a conscious observer necessarily experiences a sequence of related observer moments (or even a continuum of them). With my COMP postulate I say the same. The purely mathematically state transition function plays the role of your TIME. We do experience a continuum of observer moments simultaneously (provably with comp) but just because we are related to a continuum of execution in the "mathematical" execution of the UD. To argue that observer moments are independent of each other is to argue the negation of TIME.

With not-TIME, each observer moment has an absolute measure, the ASSA. OK. You know I "belong" to the RSSA.

The "illusion" of time (and even of different sort of time like 1-person subjective duration to local 3-person parameter-time) is implied by comp. Time is needed for machines to pass from one state to another, ie to actually compute something. I guess our divergence relies on the word "actually". If you need such a "concrete time" then you need even a "universe". Such actuality is an indexical.

Re: Many worlds theory of immortality
2 weeks ago Saibal Mitra wrote: I don't think that the MW immortality is correct at all! In a certain sense we are immortal, because the enseble of all possible worlds is a fixed static entity. So, you ''always'' find yourselve alive in one state or another. However, you won't experience youself evolving in the infinite far future. If you encounter a ''branching'' in which one of the possibilities is death, that branch cannot be said to be nonexistent relative to you. Quantum mechanics doesn't imply that you can never become unconscious, otherwise you could never fall asleep! Of course, you can never experience being unconscious. So, what to do with the branch leading to (almost) certain death? The more information your brain contains, the smaller the set of branches is in which you are alive (and consistent with your experiences stored in your brain). The set of all branches in which you could be alive doesn't contain any information at all. Since death involves complete memory loss, the branch leading to death should be replaced by the complete set of all possibilities. ...and despite reading the last paragraph several times slowly, I'm afraid I don't understand it. Are you saying there may never be a "next moment" at the point where you are facing near-certain death? It seems to me that all that is required is an observer moment in which (a) you believe that you are you, however this may be defined (it's problematic even in "normal" life what constitutes continuity of identity), and (b) you remember facing the said episode of near-certain death (ncd), and it will seem to you that you have miraculously escaped, even if there is no actual physical connection between the pre-ncd and the post-ncd observer moment. Or, another way to escape is as you have suggested in a more recent post, that there is an observer moment somewhere in the multiverse in which the ncd episode has been somehow deleted from your memory. Perhaps the latter is more likely, in which case you can look forward to never, or extremely rarely, facing ncd in your life. It all gets very muddled. If we try to ruthlessly dispense with every derivative, ill-defined, superfluous concept and assumption in an effort to simplify the discussion, the one thing we are left with is the individual observer-moments. We then try to sort these observer-moments into sets which constitute lives, identities, birth, death, amnesia, mind duplication, mind melding, multiple world branchings, and essentially every possible variation on these and other themes. No wonder it's confusing! And who is to judge where a particular individual's identity/life/body/memory begins and ends when even the most detailed, passed by committee of philosophers set of rules fails, as it inevitably will? The radical solution is to accept that only the observer-moments are real, and how we sort them then is seen for what it is: essentially arbitrary, a matter of convention. You can dismiss the question of immortality, quantum or otherwise, by observing that the only non-problematic definition of an individual is identification with a single observer-moment, so that no individual can ever "really" live for longer than a moment. Certainly, this goes against intuition, because I feel that I was alive a few minutes ago as well as ten years ago, but *of course* I feel that; this is simply reporting on my current thought processes, like saying I feel hungry or tired, and beyond this cannot be taken as a falsifiable statement about the state of affairs in the real world unless recourse is taken to some arbitrary definition of personal identity, such as would satisfy a court, for example. Let me put it a different way. Situation (a) life as usual: I die every moment and a peson is reborn every moment complete with (most) memories and other attributes of the individual who has just died. Situation (b) I am killed instantly, painlessly, with an axe every moment, and a person is reconstituted the next moment complete with (most) memories and other attributes of the individual who has just died, such that he experiences no discontinuity. Aside from the blood and mess in (b), is there a difference? Should I worry more about (b) than (a)? This is of course a commonplace thought experiment on this list, but I draw from it a slightly different conclusion: we all die all the time; death doesn't really matter, otherwise we should all be in a constant panic. --Stathis Papaioannou _ Express yourself instantly with MSN Messenger!

Re: many worlds theory of immortality: May only be the Anthropic Principle
Dear Lee, Interleaving. - Original Message - From: "Lee Corbin" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, April 27, 2005 11:00 PM Subject: RE: many worlds theory of immortality: May only be the Anthropic Principle Stephen writes you seem to be making a case of the Anthropic Principle, but I am not sure if this is your intension. (I am ignoring my own allergy to the idea that 1st person aspects can be faithfully represented by Turing algorithms.) Well, I myself had no clue that these ideas could be connected to the Anthropic Principle. [SPK] ;-) You wrote "...the vast winnowing of branches that people find themselves in..." Isn't this exactly what we would expect if we assume that any slice of the Multiverse that an observer finds itself in will be restricted to necessarily allowing for some measure of "being alive" such that a meaningful notion of "observation" can obtain? [Are we inadvertently assuming some kind of "outside of the multiverse" point of view to define this???] [LC] Could you possibly expand on this notion? Maybe with shorter sentences? :-) As for me, trying to keep the ideas simple, I often read in literature how some character is surprised to find himself alive. There have been parallels (perhaps weak ones) in my own life where I am surprised to find myself still employed. [SPK] I will try, but as often is the case these ideas are not easily explained in small sound byte size morsels, especially by someone like myself that is dislexic. ;-) There are, at least, two seperate issues here: the multiplicity of relative states of an observer and the notion of continuity of the 1st person aspect (subjective experience), i.e., that for any given notion of an observer and the possible choices that they could make of that causally impact upon them there exists one universe within which that observer could find itself. The former is easily seen to follow the notion that any universe that an observer finds itself "in" will have conditions that, at least, allow for the existence of that observer. This, for example, would exclude universes that do not have some form of gravity that would give rise to stars, planets, etc. The latter notion is not very obvious and as Bruno has pointed out we have strong reasons to believe that the 1st person aspect is not reducible to some 3rd person aspect. As an aside, I do believe that the converse is the case: any 3rd person aspect can be constructed from 1st person aspects. Another way of putting the second notion out there is to refere to the rubric, whose origin escapes me, "I am what I remember myself to be". [LC] It hasn't occurred to me that this warrants any revision, but I guess the adherents of the strong no-cul-de-sac theory should be incapable of being surprised that they were still alive. I can just hear them saying to themselves "Well, OF COURSE I'm still alive...what else could I expect? To find myself dead? Duh!" [SPK] If the observer is incapable of making an observation of a given universe, it easily follows that there is some strong reason why. One simple reason could be that that observer can not have any 1st person aspects consistent with that particular universe. To say that one is dead in such and such a universe is the same thing, unless we are going to postulate some kind of disembodied "consciousness", like a self-aware ghost. [SPK] The idea of immortality seems to assume some means by which a given observer's 1st person aspect can be continuously traced through the Multiverse. Right? Would not such a "trace" obey topological rules such as not allowing for the 1st person awareness of the effects of "cutting", "pasting", "tearing" and other kinds of topological surgery? [LC] I'm not sure that I follow. It seems to me that I experience a certain (probably mundane) discontinuity when I sleep and then wake. Other people, especially amnesiacs, or those involved in very severe injuries to the head, report discontinuities. Later on, if/when we have "learning pills", one might suddenly remember that he knew French. Since it's not so difficult to imagine this, it seems to me that all of the kinds of surgery you list above can be experienced. [SPK] Again, this is captures by: I am what I remember myself to be", or in Vaughan Pratt's terms: "I think, therefore I was". [SPK] Would these global rules not fall under the AP as well or is this outside of the AP? [LC] Perhaps you should also expand on the Anthropic Principle. I'm very hazy on it. The Weak anthropic principle seemed only to be common sense, and the Strong and Final forms, as I recall, were pretty dubious so far as I was concerned.

Re: many worlds theory of immortality: May only be the Anthropic Principle
Hi Stephen, You wrote: > >can be faithfully represented by Turing algorithms.) ...> I take the opportunity of that statement to insist on a key point which is admittedly not obvious. The fact is that I am also totally allergic to the idea that 1st person aspects can be represented. Comma. And that is the main reason I appreciate the computational hypothesis; it prevents the existence of any such representation. This is a consequence of two things: 1) The first person possesses an unbreakable umbilical chord with truth (it is related to what is called "knowledge incorrigibility"); 2) by Tarski theorem the concept of truth on a machine cannot be represented in any way in the machine. In particular if we define (a little bit contra Rafe Champion(for-list) knowledge of p by [provability of p] + [truth of p] (more or less Theaetetus' definition), although provability and knowledge can be shown to be "third person" equivalent, they can also be shown first person NOT equivalent. I even think that the comp hyp, thanks to incompleteness, is the most powerful vaccine ever find against any attempt to reduce a first person to any third person notion, and this in a third person communicable way. This makes me optimistic for the long run ... Best regards, Bruno http://iridia.ulb.ac.be/~marchal/

RE: many worlds theory of immortality
Jesse, I've deleted everything, it was getting too messy. I hope this (semi-)mathematical formulation captures your argument correctly: Suppose you start with one individual, your friend, on a computer network which has infinite resources and will grow exponentially forever. This individual will be duplicated every unit time period, so that after n generations, there will be 2^n copies. Suppose there is a probability p(n) that, during a unit time period, any single individual in the nth generation will be effectively deleted, whether through suicide, murder, local hardware failure, or whatever. To simplify the maths, assume that if at least one copy survives, the rest of the 2^n copies in that generation will be restored from memory; but if all the copies are deleted, then that will be Real Death for your friend. Now, the probability of Real Death in the nth generation, given the above, is p(n)^(2^n). If p(n) is a constant, call it k, this probability will clearly decrease with each generation. The probability that your friend will never suffer Real Death is then given by the infinite product: (1-p(0)^(2^0))*(1-p(1)^(2^1))*(1-p(2)^(2^2))*... which I believe converges to a value between 0 and 1 (too lazy to work it out now) and is another way of making your point, with the geometric series, that even with an always-nonzero probability that a given individual will die, if this probability is always decreasing due to exponential growth of copies of the individual, the probability that at least some copies will survive indefinitely does not limit to zero. Now, look at p(n) again. This time, let's say it is not k, but a random real number greater than zero, smaller than 1, with k being the mean of the distribution. At first glance, it may appear that not much has changed, since the probabilities will "on average" be the same, over a long time period. However, this is not correct. In the above product, p(n) can go arbitrarily close to 1 for an arbitrarily long run of n, thus reducing the product value arbitrarily close to zero up to that point, which cannot subsequently be "made up" by a compensating fall of p(n) close to zero, since the factor 1-p(n)^(2^n) can never be greater than 1. (Sorry I haven't put this very elegantly.) The conclusion is therefore that if p(n) is allowed to vary randomly, Real Death becomes a certainty over time, even with continuous exponential growth forever. If you have a real world network, or simulated sentient beings, I don't believe it is possible eliminate the random lement in this parameter. --Stathis Papaioannou _ Update your mobile with a hot polyphonic ringtone: http://fun.mobiledownloads.com.au/191191/index.wl?page=191191polyphonicringtone

You could be right, but I don't think you have good justification for being so confident that you're right. It seems plausible to me that the larger the number of copies that exist already, the smaller the variations in the doubling rate, the smaller the fluctuations in those derivatives you mention, and the smaller the probability that a temporary period of negative growth will continue for a given amount of time. Are you 100% certain this is wrong? Do you disagree that the average actions of a googolplex copies will probably be less uncertain than the average actions of 50 copies, for example? It is analogous to the gambler's fallacy: given long enough, the gambler will lose everything, and then he won't have any funds to attempt to recover his losses. If the odds are slightly in his favor on each individual bet (say, for each dollar he bets there is a 50% chance he'll lose it and a 50% chance he'll win $2.01), this isn't true; the larger the amount of money he has already, the more predictable his total winnings on each round of betting, so you could prove that there is some finite probability his money will never go to zero in an infinite number of rounds of betting.

The other is the probability that the actual hardware will work according to specification. I don't think you should conflate the two, effectively arguing that the hardware will work to specification because that is part of the specification! [Jesse] I don't think I ever said anything about the probability involving software only. If you have a distributed computing network (such that destroying any part of it won't cause a global breakdown), and more and more of the universe is constantly being gobbled up and converted into computing power, then perhaps the probability of all the hardware in the universe breaking down would decrease geometrically as well, on average. Assume that when I talk about the probability of all copies of you being destroyed decreasing like 1/8+1/16+1/32+..., this probability takes into account all possible causes of failure, including software problems, destruction of hardware, and even stuff like the possibility that some other enemy groups of A.I.'s will attempt to erase all copies of you. [Stathis] Returning to the original question, once you have settled into your new home, what is to stop all your friends disappearing, as before? The computer will try to prevent this from happening, and you could probably try the geometric series trick again (i.e. decreasing probability that your friends disappear), but in this case there will be nothing tying you to those ever-rarer branches where the hardware works as it is supposed to. [Jesse] But my point is that it doesn't necessarily have to be a matter of "ever-rarer" branches--even aside from quantum immortality, it might be true that in 3/4 (or whatever) of all branches stemming from a given point in time, any A.I. around at that time will have at least some copies around in the giant computing network forever. You seem to be treating the proposed ever-decreasing failure rate per clock cycle as if it is something that will just happen inexorably once the denizens of the far future decide to build this computer. No, I'm just suggesting that it's possible that once these far future people have gotten a good start on building this ever-increasing *network* of computers, the probability of every single computer in the system breaking down may, in an average world, be decreasing geometrically, perhaps for no other reason that the number of computers is increasing geometrically as more and more of the universe is converted into computing machines (which in a way would be no more surprising than the idea that the population tends to increase geometrically when resources are unlimited and death rates are low). This need not happen "inexorably" since it wouldn't be true in every single history, I'm just suggesting the average pattern if you look at all possible futures stemming from a given time may involve such a geometric decrease in failure probability. Are you suggesting it is somehow logically impossible that the *average* pattern would be a geometric one? You may as well say that in the future, there will be computers with a mean time between failure of 10^10^100 years, or whatever arbitrarily large number you choose. Sure, if you have a decentralized network of computers like the internet, then no matter what the average failure rate of an individual computer in the network, you can keep the failure rate of the entire network as arbitrarily low as you want by making the number of computers in the network sufficiently large. The problem is not in conceiving of such super-machines, it is in the details of design and implementation. Again, it need not be a question of super-machines, just a question of sheer numbers. I imagine that in the future there may be multiple attempts to build computers which will squeeze an infinite period of subjective time into a finite period of real time, in the way you have described, I wasn't necessarily suggesting an infinite number of computations in a finite physical time a la Tipler...an infinite number of computations in an infinite physical time a la Dyson would be fine too (to inhabitants of the simulation it wouldn't make any difference). and like any other engineering project, the success rate will increase with increasing experience and resources, but even the "last gasp" effort in the moment before the big crunch will only succeed in an infinitesimally small proportion of multiverse branches. I don't see why it is logically impossible that it could succeed in a non-infinitesimal proportion of multiverse branches, due to an on-average geometric decrease in the probability of the whole system breaking down.

RE: many worlds theory of immortality
Jesse Mazer writes: [Stathis] There are two separate probabilities to consider here. One is the probability (3/4, as you show) that civilization will never break down if implemented on a computer with behaviour as specified above. The other is the probability that the actual hardware will work according to specification. I don't think you should conflate the two, effectively arguing that the hardware will work to specification because that is part of the specification! [Jesse] I don't think I ever said anything about the probability involving software only. If you have a distributed computing network (such that destroying any part of it won't cause a global breakdown), and more and more of the universe is constantly being gobbled up and converted into computing power, then perhaps the probability of all the hardware in the universe breaking down would decrease geometrically as well, on average. Assume that when I talk about the probability of all copies of you being destroyed decreasing like 1/8+1/16+1/32+..., this probability takes into account all possible causes of failure, including software problems, destruction of hardware, and even stuff like the possibility that some other enemy groups of A.I.'s will attempt to erase all copies of you. [Stathis] Returning to the original question, once you have settled into your new home, what is to stop all your friends disappearing, as before? The computer will try to prevent this from happening, and you could probably try the geometric series trick again (i.e. decreasing probability that your friends disappear), but in this case there will be nothing tying you to those ever-rarer branches where the hardware works as it is supposed to. [Jesse] But my point is that it doesn't necessarily have to be a matter of "ever-rarer" branches--even aside from quantum immortality, it might be true that in 3/4 (or whatever) of all branches stemming from a given point in time, any A.I. around at that time will have at least some copies around in the giant computing network forever. You seem to be treating the proposed ever-decreasing failure rate per clock cycle as if it is something that will just happen inexorably once the denizens of the far future decide to build this computer. No, I'm just suggesting that it's possible that once these far future people have gotten a good start on building this ever-increasing *network* of computers, the probability of every single computer in the system breaking down may, in an average world, be decreasing geometrically, perhaps for no other reason that the number of computers is increasing geometrically as more and more of the universe is converted into computing machines (which in a way would be no more surprising than the idea that the population tends to increase geometrically when resources are unlimited and death rates are low). This need not happen "inexorably" since it wouldn't be true in every single history, I'm just suggesting the average pattern if you look at all possible futures stemming from a given time may involve such a geometric decrease in failure probability. Are you suggesting it is somehow logically impossible that the *average* pattern would be a geometric one? You may as well say that in the future, there will be computers with a mean time between failure of 10^10^100 years, or whatever arbitrarily large number you choose. Sure, if you have a decentralized network of computers like the internet, then no matter what the average failure rate of an individual computer in the network, you can keep the failure rate of the entire network as arbitrarily low as you want by making the number of computers in the network sufficiently large.
