By "measures as" I mean as in what was the probability to experience exact this moment, from the set of all possible moments that "exists" (or can be experienced). And by "measures as 1" I mean, that if several physical "carriers" produces exact same experience, that counts as 1 experience in the grand total set of experiences, and probability to feel exactly that is 1/(count of all different experiences). Now I know this is controversial and counter intuitive. But still this is quite plausible, given what we even know about consciousness. Like, if consciousness emerges on the level of algorithms and logic, then why would it care, how many physical things produces it? If one were asked, how many movies about human pretending to be blue alien on planet Pandora does he know, the answer would probably be 1 and not the number of digital Avatar copies ever made.
Hmm. I still think you need rigor in how you know what differences are important and which are ignored. There is no such thing as actually identical universe-states across branches, so you're somehow collapsing different physical things into "same" experience.
If you asked how many movies does a person know on that, they'd likely say 1, because they're collapsing all the copies, which vary only trivially. If you ask "what's the probability that a randomly chosen disc in a used DVD store is Avatar", then the ratio of individual copies ...
Lets assume few things:
1. Many Worlds is real.
2. All identical consciousnesses measures as 1 in anthropics . So if we have set of consciousness: 1xA,1xB and 1000000xC, it is still 1/3 chance, to perceive being C.
Now say some intelligent being (i.e. human) starts another human brain simulation on silicon chip. The operations it does are all discrete, so despite the chip splitting in to many chips in many worlds, the simulated consciousness itself remain just 1 (because of #2 assumption).
But that is not true for human who started the simulation as he differs somehow in every Everett branch and reaches billions different consciousnesses really fast.
Is there some mistake in reasoning, that real persons should heavily outweigh simulations, despite, how many of them are running, given such assumptions?
