We don't need to describe the scenarios precisely physically. All we need to do is describe it in terms of the agent's epistemology, with the same sort of causal surgery as described in Eliezer's TDT. Full epistemological control means you can test your AI's decision system.

This is a more specific form of the simulational AI box. The rejection of simulational boxing I've seen relies on the AI being free to act and sense with no observation possible, treating it like a black box, and somehow gaining knowledge of the parent world through inconsistencies and probabilities and escaping using bugs in its containment program. White-box simulational boxing can completely compromise the AI's apparent reality and actual abilities.

Resurrect one individual, filling gaps with random quantum noise.

Resurrect all possible individuals with all combinations of noise.

That is a false trichotomy. You're perfectly capable of deciding to resurrect some sparse coverage of the distribution, and those differences are not useless. In addition, "the subject is almost exactly resurrected in one of the universes" is true of both two and three, and you don't have to refer to spooky alternate histories to do it in the first place.

...Okay? One in ten sampled individuals will be gay. You can do that. Does it really matter when you're resurrecting the dead?

Your own proposal is to only sample one, and call the inaccuracy "acausal trade," which isn't even necessary in this case. The AI is missing 100 bits. You're already admitting many-worlds. So the AI can simply draw those 100 bits out of quantum randomness, and in each Everett branch, there will be a different individual. The incorrect ones you could call "acausal travelers," even though you're just wrong. There will still be the "correct" individual, the exact descendant of this reality's instance, in one of the Everett branches. The fact that it is "correct" doesn't even matter, there is only ever "close enough," but the "correct" one is there.

The evidence provided of any dead person produces a distribution on human brains, given enough computation. The more evidence there is, the more focused the distribution. Given post-scarcity, the FAI could simply produce many samples on each distribution.

This is certainly a clever way of producing mind-neighbors. I find problems with these sorts of schemes for resurrection, though. Socioeconomic privilege, tragedy of the commons, and data rot, to be precise.

You're confusing the intuitive notion of "simple" with "low Kolmogorov complexity"

I am using the word "simple" to refer to "low K-complexity." That is the context of this discussion.

It does if you look at the rest of my argument.

The rest of your argument is fundamentally misinformed.

Step 1: Stimulation the universe for a sufficiently long time.

Step 2: Ask the entity now filling up the universe "is this an agent?".

Simulating the universe to identify an agent is the exact opposite of a short referent. Anyway, even if simulating a universe were tractable, it does not provide a low complexity for identifying agents in the first place. Once you're done specifying all of and only the universes where filling all of space with computronium is both possible and optimal, all of and only the initial conditions in which an AGI will fill the universe with computronium, and all of and only the states of those universes where they are actually filled with computronium, you are then left with the concept of universe-filling AGIs, not agents.

You seem to be attempting to say that a descriptor of agents would be simple because the physics of our universe is simple. Again, the complexity of the transition function and the complexity of the configuration states are different. If you do not understand this, then everything that follows from this is bad argumentation.

What do you mean by that statement? Kolmogorov complexity is a property of a concept. Well "reducing entropy" as a concept does have low Kolmogorov complexity.

It is framed after your own argument, as you must be aware. Forgive me, for I too closely patterned it after your own writing. "For an AGI to be successful it is going to have to be good at reducing entropy globally. Thus reducing entropy globally must be possible." That is false, just as your own argument for a K-simple general agent specification is false. It is perfectly possible that an AGI will not need to be good at recognizing agents to be successful, or that an AGI that can recognize agents generally is not possible. To show that it is, you have to give a simple algorithm, which your universe-filling algorithm is not.

Doesn't that undermine the premise of the whole "a godless universe has low Kolmogorov complexity" argument that you're trying to make?

Again, there is a difference between the complexity of the dynamics defining state transitions, and the complexity of the states themselves.

But, the AGI can. Agentiness is going to be a very important concept for it. Thus it's likely to have a short referent to it.

What do you mean by "short referent?" Yes, it will likely be an often-used concept, so the internal symbol signifying the concept is likely to be short, but that says absolutely nothing about the complexity of the concept itself. If you want to say that "agentiness" is a K-simple concept, perhaps you should demonstrate that by explicating a precise computational definition for an agent detector, and show that it doesn't fail on any conceivable edge-cases.

Saying that it's important doesn't mean it's simple. "For an AGI to be successful it is going to have to be good at reducing entropy globally. Thus reducing entropy globally must have low Kolmogorov complexity."

An AGI has low Kolmogorov complexity since it can be specified as "run this low Kolmogorov complexity universe for a sufficiently long period of time".

That's a fundamental misunderstanding of complexity. The laws of physics are simple, but the configurations of the universe that runs on it can be incredibly complex. The amount of information needed to specify the configuration of any single cubic centimeter of space is literally unfathomable to human minds. Running a simulation of the universe until intelligences develop inside of it is not the same as specifying those intelligences, or intelligence in general.

Also the AGI to be successful is going to have to be good at detecting agents so it can dedicated sufficient resources to defeating/subverting them. Thus detecting agents must have low Kolmogorov complexity.

The convenience of some hypothetical property of intelligence does not act as a proof of that property. Please note that we are in a highly specific environment, where humans are the only sapients around, and animals are the only immediately recognizable agents. There are sci-fi stories about your "necessary" condition being exactly false; where humans do not recognize some intelligence because it is not structured in a way that humans are capable of recognizing.

I don't think mind designs are dependent on their underlying physics. The physics is a substrate, and as long as it provides general computation, intelligence would be achievable in a configuration of that physics. The specifics of those designs may depend on how those worlds function, like how jellyfish-like minds may be different from bird-like minds, but not the common elements of induction, analysis of inputs, and selection of outputs. That would mean the simplest a priori mind would have to be computed by the simplest provision of general computation, however. An infinitely divine Turing Machine, if you will.

That doesn't mean a mind is more basic than physics, though. That's an entirely separate issue. I haven't ever seen a coherent model of God in the first place, so I couldn't begin to judge the complexity of its unproposed existence. If God is a mind, then what substrate does it rest on?

The non-triviality arises from technical considerations

The laws of physics as we know them are very simple, and we believe that they may actually be even simpler. Meanwhile, a mind existing outside of physics is somehow a more consistent and simple explanation than humans having hardware in the brain that promotes hypotheses involving human-like agents behind everything, which explains away every religion ever? Minds are not simpler than physics. This is not a technical controversy.

If this post doesn't get answered, I'll repost in the next open thread. A test to see if more frequent threads are actually necessary.

I'm trying to make a prior probability mass distribution for the length of a binary string, and then generalize to strings of any quantity of symbols. I'm struggling to find one with the right properties under the log-odds transformation that still obeys the laws of probability. The one I like the most is P(len(x)) = 1/(x+2), as under log-odds it requires log(x)+1 bits of evidence for strings of len(x) to meet even odds. For a length of 15, it uses all 4 bits in 1111, so its cost is 4 bits.

The problem is that 1/(x+2) does not converge, making it an improper prior. Are there some restrictions by which I can use this improper prior, or to find a proper prior with similarly desirable qualities?
