I consider it bad form to do such a massive rewrite, thereby obsoleting the entire previous comment stream.
Regarding your new post, I think you need to taboo the word 'measure' and rewrite all your posts without it. It would make things much more clear for the rest of us. When communicating with others, it is more important to be clear and precise than it is to be compact, and your use of 'measure' is neither clear nor precise to a good number of your audience.
What the frakking Hell? Dust theory on its face gives almost uniformly false predictions. Now, we are admittedly confused about how to assign probabilities in cases like this, but confusion is a bad reason to adopt a radical new view of reality. That's not how confusion is supposed to work.
Eitan, I think you should set down exactly what you take "Dust Theory" to mean, for at least the following reasons: Not everyone has read "Permutation City"; those who have may have forgotten some details; the book may not nail down all those details firmly enough to make the term unambiguous; you might mean by it something slightly different from what Egan does.
(For the avoidance of doubt, that last one would not necessarily be a bad thing. The most credible thing deserving the name "Dust Theory" might not be quite the same as what's described in what is, after all, a work of fiction with its own narrative constraints.)
Can someone explain me what's the point of this post? No offense intended; reading the first paragraph made my mind literally explode wondering what the hell I've just read.
I haven't read Permutation City (a comment mentioned it) and in fact I approached all LW material I've read with only my previous experience and reasoning abilities, and ALL topics such as this that feel so meta, out-of-this-world, and seemingly with no practical implications make no sense to me.
Am I missing something?
Why are you in a simulation and not a Boltzmann brain? If the universe goes on forever after heat death, then there will be an infinite number of Boltzmann brain yous.
Now you just repeating Bostrom simulation argument. But why you rewrite early post is not clear as it will be misleading for commenters.
if you are still here, check this: https://arxiv.org/abs/1712.01826
Seems you were right after all with dust theory.
Also, is there any way to see your original version of the post?
Oh god I still can't get this thought out of my head. Can someone please tell me what they think of my solution to the problem?
I just read 'The Finale of the Ultimate Meta Mega Crossover' again. Is there a motivation for entities with unlimited computing power to simulate all possible programs in order? Or to take an interest in beings like me? Would that be enough to remove most of my measure from 'real' universes? I think probably not, but I need to be sure. I'm not thinking too clearly now.
EDIT: Wait a minute, this becomes more plausible after realizing...
I think you are making too many inferences without sufficiently accounting for possible errors in your assumptions and the inferences themselves.
Upvoted because I've come to similar conclusions and believe that simulation anthropics are interesting and worth discussing.
I didn't read your first version of the post. I guess you are being downvoted because of some combination of poor/obtuse presentation ('dust theory' is a poor name, it suggests ultra low probability worlds), history of presenting 'crazy' ideas, etc. I feel somewhat bad for you so I may create another supporting thread to present and discuss this general topic.
Also, it would really help if you link to earlier discuss of anthropics - some of these issues have been discussed at length here in the past.
I feel sorry that I inspired this thread by my comment but did not elaborate it enough. Basically I have multilevel depositorium of wild ideas, with wildest are on the top. (I think I should make a map about it :) So I peak an idea from the next level of the depositorium, not the wildest one, to help Eltan. As I know that it is wild idea I can't take it for granted and I understand that it needs more profound explanation. As I write slowly on foreign language, I was hesitated to go for long explanation which will only spoil my carma afterwords.
Basically,...
When I was a youth I wondered where my consciousness came from. How it came that I perceived, that my consciousness was mine. Where it came from. What good luck that the consciousness that was I had such good parents and home. I could have been someone else, someone suffering. I conceived many consciousness instances like processors waiting for a being (e.g. a baby) to become conscious and start 'executing' in it. But where were these? Were these the souls? And were did they go when we die?
It was quite obvious that even if these instances 'persisted' that...

Assume that our minds really do work the way Unification tells us: what we are experiencing is actually the sum total of every possible universe which produces them. Some universes have more 'measure' than others, and that is typically the stable ones; we do not experience chaos. I think this makes a great deal of sense- if our minds really are patterns of information I do not see why a physical world should have a monopoly on it.
Now to prove that we live in a Big World. The logic is simple- why would something finite exist? If we're going to reason that some fundamental law causes everything to exist, I don't see why that law restricts itself to this universe and nothing else. Why would it stop? It is, arguably, simply the nature of things for an infinite multiverse to exist.
I'm pretty terrible at math, so please try to forgive me if this sounds wrong. Take the 'density' of physical universes where you exist- the measure, if you will- and call it j. Then take the measure of universes where you are simulated and call it p. So, the question become is j greater than p? You might be thinking yes, but remember that it doesn't only have to be one simulation per universe. According to our Big World model there is a universe out there in which all processing power (or a significant portion) as been turned into simulations of you.
So we take the amount of minds being simulated per universe and call that x. Then the real question becomes if j > px. What sort of universe is common enough and contains enough minds to overcome j? If you say that approximately 10^60 simulated human minds could fit in it (a reasonable guess for this universe) but that such universes are five trillion times rarer than the universe we live in, than it's clear that our own 'physical' measure is hopelessly lower than our simulated measure.
Should we worry about this? It would seem highly probable that in most universes where I am being simulated I once existed in, or humans did, since the odds of randomly stumbling upon me in Mind Space seem unlikely enough to ignore. Presumably they are either AIs gone wrong or someone trying to grab some of my measure, for whatever reason.
As way of protecting measure, pretty much all of our postsingularity universes would divide up the matter of the universe for each person living, create as many simulations as possible of them from birth, and allow them to go through the Singularity. I expect that my ultimate form is a single me, not knowing if he is simulated or not, with billions of perfect simulations of himself across our universe, all reasoning the same way (he would be told this by the AI, since there isn't any more reason for secrecy). This, I think, would be able to guard my measure against nefarious or bizarre universes in which I am simulated. It cannot just simulate the last few moments of my life because those other universes might try to grab younger versions of me. So if we take j to be safe measure rather than physical measure, and p to be unsafe or alien, it becomes jx > px, which I think is quite reasonable.
I do not think of this as some kind of solipsist nightmare; the whole point of this is to simulate the 'real' you, the one that really existed, and part of your measure is, after all, always interacting in a real universe. I would suggest that by any philosophical standard the simulations could be ignored, with the value of your life being the same as ever.
