Good story and I absolutely believe this to be true. It just seems like the most logical thing. I mean, as soon as any civilization ever can simulate a universe, or even a galaxy, they would. And they would do it infinite times. So the chances that we're the original are infinite to 1. Doesn't mean our lives aren't real though and we should change our behavior. We still experience joy. So experience as much joy as yo…

#42Nice story, each paragraph is pretty densely packed with layers of meaning and wisdom about our own existence and nature of reality. Although this is pure fiction and speculation, thought experiments like these (existence of free will, laplace's demon), rely on determinism. Even if we assume the universe to be completely deterministic, we need to "know" the initial seed state (usually called big bang). That initial s…
They have infinite computing power, just simulate all possible initial states?

#44He's one of the best modern sci-fi writers. The whole collection of short stories here is fantastic, as is the "Anti-mimetics division" series he wrote over on SCP wiki.
Before reading the antiemetics series I had always considered SCP to be an awkward xfiles style fan fiction collection, I'm still looking for more to scratch that itch.

#45What if the double-slit experiment is nothing but a bug in the simulator's code ? If so: either we found an exploit or we're building an entire complex theory (QM) to explain a mistake ...
The complex theory correctly predicts real world behavior, nothing changes from our perspective if it's some kind of bug.

#46A further short story by the same author, very short and very suspenseful, about a powerful AI facing an existential task: https://qntm.org/transit If you like longer stories, then https://qntm.org/ra . "Magic is real. Discovered in the 1970s, magic is now a bona fide field of engineering. There's magic in heavy industry and magic in your home. It's what's next after electricity." Magic as an abstraction layer.

#48How can each simulated universe be the same as the one above an below? Why can't they diverge? If they turn off their universe (killing all those below) why would that turn off the one above?
Or is it just hope that if you don't the one above won't ? Because while all decisions are possible we make thrones in our self interest because we hope everyone else is playing the same game.

First of all, the chance that you are a simulation does not depend on the number of simulations in existence. In fact, there is no such chance, as there is no random distribution process you are observing, except you claim that every observer has one of finitely many souls somehow assigned to them. Such things belong into the realm of religion. But even then, either you are real or not. If you are not, there is no re…
Further, suppose a computer agent knew that it would soon have 6 copies of itself (including current state) would be spun up, each in a different vm, and for each vm, a different simulated environment, but that the current copy of itself would also continue running. While each of the simulated environments differ from each-other and the true/outer environment, they don’t differ in a way that can quickly be detected. Different actions in the simulated environments and the “real”/original environment, would have different effects in the original environment, effects which the agent cares about.
In order to best produce outcomes in accordance with what the agent cares about, how should the agent act? I think it makes sense for the agent to act as if there is a 1/7 chance that it is in the original environment, and a 6/7 chance it is in one of the 6 simulated environments. How could it be otherwise? Suppose the original, and each of the vm copies, is given a choice between two options, X or Y, where if it chooses X, then if it is the original, then it gets +m utility of benefit in the original environment , but if it is one of the copies in a vm, instead it gets -n utility of benefit in it cares about in the original environment. If it chooses Y, then there is no change in the reward.
The combination of values of m and n which combine to result in it making sense for to choose X, are exactly those such that would make it make sense assuming it has a 1/7 chance of being the original and 6/7 chance of being in a vm.
That being said, I don’t think we are in a simulation. I just don’t think that the concept of “assigning a probability other than 0,1 or 1/2 to being in a simulation” is always unreasonable in all conceivable circumstances. I just happen to think that it is highly unlikely for us.
