Adam Brown: belief

26 Dec 2024 Dwarkesh Podcast Adam Brown — Bubble universes, space elevators, & AdS/CFT

“I think in part people's intuition is maybe formed in cases like extinction, where if you have an animal that's going extinct, if half of the animals get wiped out, that's somehow less bad than if both halves of the animals get wiped out.”

Transcript context

…The weighted average ends up close to nothing. But I'm like, that really sucks, that's actually happening. Yeah, I think there are a number of ways to think about this. I think in part people's intuition is maybe formed in cases like extinction, where if you have an animal that's going extinct, if half of the animals get wiped out, that's somehow less bad than if both halves of the animals get wiped out. But that's because they really aren't going to interact in the future. And there's the possibility of the. Those don't have non-overlapping future light cones, the two populations of some possibly extinct animal. It's also the case that this is a pretty like Born's rule, narrowly defined, does not really have anything to say about this how one should calculate the total utility. It's just more of a sort of the natural utility measure that would come out of this. Particularly when you get to the cosmological multiverse. I think that these are very difficult questions to answer your intuition that perhaps two different universes in which how we calculate those do we just add together the utility in both or is there some non-linearity to do with it? Basically, for the cosmological multiverse, there isn't a particularly good way to decide what the weighting factor should be. We don't have the same equivalent of Born's rule in quantum mechanics. And I think it's at least open for opinions like yours to be to be. In fact, there should be some better way in which we calculate it. That's not just a linear function of. These different kinds of infinities is there some sense in which some are more fundamental than others. That is, maybe the bubbles are artifacts of what's actually happening on the wave function, or vice versa.…
