Let X be something bad. If X is true it is something you and nearly every other person should rightly fear. If, however, no one but you fears X than either (1) you are mistaken, or (2) you have some special information or insight that everyone else lacks. Logically, it's almost certainly (1). So if you fear X but Eliezer, Bostrom, and Hanson don't appear to, take comfort from their lack of fear even if you don't understand it.

While (2) is possible, the probability is low. Academics love counter-intuitive problems and think about them a lot. Bostrom might not understanding Dust Theory in the way that he doesn't understand the power of the Time Cube.

Few people know about Dust Theory, even fewer understand it intuitively.

Dust theory is beautiful and terrifying, but what do you say to Egan's argument against it: http://gregegan.customer.netspace.net.au/PERMUTATION/FAQ/FAQ.html

Erm, you mean his argument that we would expect to find ourselves in a more chaotic universe? Well, it might be that such observers are less 'dense' than ones in a stable universe (I never grasped the mathematics of it), and if that's the case than I don't see how the argument works. But then the opposite problem applies- our universe is far too complex, and relies upon contingencies that are highly improbable, merely for observers to exist. The only solution for the 'Big World' is that universes like these have a high-base rate, and that this really is the most common type of scenario that produces life. But that can't save Dust Theory, and probably not Ultimate Ensemble either.

On the other hand, if Egan is right, losing mental awareness in a chaotic universe could have the opposite effect of what I first thought- propelling you into more stable worlds by virtue of your continued existence. This may explain our current observations. But that's a very cloudy line of thinking. Maybe such beings "join" with sleeping human infants if the observations match theirs. But still, this universe seems too stable; why would they have defaulted to this one? And why would the most common type of observer be similar enough to human even to have that much in common?

I'm pretty sure someone who knows what they're talking about could put this question to rest. But no one here will even understand it.

In that case most of your measure is in stable universes and dust theory isn't anything to worry about.

But that can't be the case, as isn't the whole point of dust theory that basically any set of relations can be construed as a computation implementing your subjective experience, and this experience is self-justifying? If that's the case the majority of your measure must be dust.

Dust theory has a weird pulled-up-by-your-own bootstraps taste to it and I have a strong aversion to regarding it as true, but Egan's argument against it is the best I can find and it's not entirely satisfying but should be sufficiently comforting to allow you to sleep.

There are different ways of defining ,measure. DT guarantees that lack of continuity, and therefore low density, won't be subjectivtly noticeable....at least, it will look like chaotic observations , not feral like "I'm dead"

Maybe you could include:

construed as a computation BY WHOM?
Computation is a process, and not any process, so the idea of an instantaneous computational state.

(There is a possible false dichotomy there: consciousness isnt the output of a computation that takes a lifetime to perform, but there could be still be millions of computatioNs required to generate a "specious present")

Not necessarily to you. It doesn't have to make much sense to you at all. But our observations are orderly, and that is something that can't be explained by the majority of our measure being dust. Why would it default to this?

If you make Egan's assumption, I think it is an extremely strong argument.

Why don't you buy it?

Comment author: Eitan_Zohar 12 July 2015 04:11:12AM * 0 points [-]

I don't reject it, I simply think that Dust Theory based on this assumption is so unlikely that we may as well assume the opposite- that different patterns can be more common; have more measure, than others.
