No. Any FAI (ETA: or other AGI) has to be a singleton to last for long. Otherwise I can build a uFAI that might replace it.
Suppose your AI only does a few things that everyone agrees on, but otherwise "doesn't interfere". Then I can build another AI, which implements values people don't agree on. Your AI must either interfere, or be resigned to not being very relevant in determining the future.
Will it only interfere if a consensus of humanity allows it to do so? Will it not stop a majority from murdering a minority? Then it's at best a nice-to-have, but most likely useless. After people successfully build one AGI, they will quickly reuse the knowledge to build more. The first AGI that does not favor inaction will become a singleton, destroying the other AIs and preventing future new AIs, to safeguard its utility function. This is unavoidable. With truly powerful AGI, preventing new AIs from gaining power is the only stable solution.
Yeah, that's worked really well for all of human history so far.
First, they may not factually wrong about the events they predict in the real world - like everyone dying - just wrong about the supernatural parts. (Especially if they're themselves working to bring these events to pass.) IOW, this may not be a factual belief to be corrected, but a desired-by-them future that others like me and you would wish to prevent.
Second, you agreed the CEV of groups of people may contain very few things that they really agree on, so you can't even assume they'll have a nontrivial CEV at all, let alone that it will "fix" values you happen to disagree with.
I have no idea what your FAI will do, because even if you make no mistakes in building it, you yourself don't know ahead of time what the CEV will work out to. If you did, you'd just plug those values into the AI directly instead of calculating the CEV. So I'll want to bomb you anyway, if that increases my chances of being the first to build a FAI. Our morals are indeed different, and since there are no objectively distinguished morals, the difference goes both ways.
Of course I will dedicate my resources to first bombing people who are building even more inimical AIs. But if I somehow knew you and I were the only ones in the race, I'd politely ask you to join me or desist or be stopped by force.
As long as we're discussing bombing, consider that the SIAI isn't and won't be in a position to bomb anyone. OTOH, if and when nation-states and militaries realize AGI is a real-world threat, they will go to war with each trying to prevent anyone else from building an AGI first. It's the ultimate winner-take-all arms race.
This is going to happen, it might be happening already if enough politicians and generals had the beliefs of Eliezer about AGI, and it will happen (or not) regardless of anyone's attempts to build any kind of Friendliness theory. Furthermore, a state military planning to build AGI singleton won't stop to think for long before wiping your civilian, unprotected FAI theory research center off the map. Either you go underground or you cooperate with a powerful player (the state on whose territory you live, presumably). Or maybe states and militaries won't wise up in time, and some private concern really will build the first AGI. Which may be better or worse depending on what they build.
Eventually, unless the whole world is bombed back into pre-computer-age tech, someone very probably will build an AGI of some kind. The SIAI idea is (possibly) to invent Friendliness theory and publish it widely, so that whoever builds that AGI, if they want it to be Friendly (at least to themselves!), they will have a relatively cheap and safe implementation to use. But for someone actually trying to build an AGI, two obvious rules are:
If the majority and the minority are so fundamentally different that their killing each other is not forbidden by the universal human CEV, then no. On what moral grounds would it do the prevention?
Until everybody agree that this new AGI is not good after all. Then the original AGI will interfere and dismantle the new one (the original is still the first and the strongest).
But I can be sure that CEV fixes values that are based on false factual beliefs - this is a part of the definition of CEV.
But you can be sure that it is something about which you (and everybody) would agree, either directly or if you were more intelligent and knew more.
But there may be a partial ordering between morals, such that X<Y iff all "interfering" actions (whatever this means) that are allowed by X are also allowed by Y. Then if A1 and A2 are two agents, we may easily have:
~Endorses(A1, CEV<A2>) ~Endorses(A2, CEV<A1>) Endorses(A1, CEV<A1+A2>)
Endorses(A2, CEV<A1+A2>)
[assuming Endorses(A, X) implies FAI<X> does not perform any non-interfering action disagreeable for A]
Well, don't you think this is just ridiculous? Does it look like the most rational behavior? Wouldn't it be better for everybody to cooperate in this Prisoner's Dilemma, and do it with a creditable precommitment?
I don't understand what you mean by "fundamentally different". You said the AI would not do anything not backed by an all-human consensus. If a majority of humanity wishes to kill a minority, obviously there won't be a consensus to stop the killing, and AI will not interfere. I prefer to live in a universe whose living AI does interfere in such a case.
Libertarianism is one moral principle that would argue for prevention. So would most varieties of utilitarianism (ignoring utility monsters and such). Again, I would prefer living with an AI hard-coded to one of those moral ideologies (though it's not ideal) over your view of CEV.
Forever keeping this capability in reserve is most of what being a singleton means. But think of the practical implications: it has to be omnipresent, omniscient, and prevent other AIs from ever being as powerful as it is - which restricts those other AIs' abilities in many endeavors. All the while it does little good itself. So from my point of view, the main effect of successfully implementing your view of CEV may be to drastically limit the opportunities for future AIs to do good.
And yet it doesn't limit the opportunity to do evil, at least evil of the mundane death & torture kind. Unless you can explain why it would prevent even a very straightforward case like 80% of humanity voting to kill the other 20%.
But you said it would only do things that are approved by a strong human consensus. And I assure you that, to take an example, the large majority of the world's population who today believe in the supernatural will not consent to having that belief "fixed". Nor have you demonstrated that their extrapolated volition would want for them to be forcibly modified. Maybe their extrapolated volition simply doesn't value objective truth highly (because they today don't believe in the concept of objective truth, or believe that it contradicts everyday experience).
Yes, but I don't know what I would approve of if I were "more intelligent" (a very ill defined term). And if you calculate that something, according to your definition of intelligence, and present me with the result, I might well reject that result even if I believe in your extrapolation process. I might well say: the future isn't predetermined. You can't calculate what I necessarily will become. You just extrapolated a creature I might become, which also happens to be more intelligent. But there's nothing in my moral system that says I should adopt the values of someone else because they are more intelligent. If I don't like the values I might say, thank-you for warning me, now I shall be doubly careful not to evolve into that kind of creature! I might even choose to forego the kind of increased intelligence that causes such an undsired change in my values.
Short version: "what I would want if I were more intelligent (according to some definition)" isn't the same as "what I will likely want in the future", because there's no reason for me to grow in intelligence (by that definition) if I suspect it would twist my values. So you can't apply the heuristic of "if I know what I'm going to think tomorrow, I might as well think it today".
I think you may be missing a symbol there? If not, I can't parse it... Can you spell out for me what it means to just write the last three Endorses(...) clauses one after the other?
It may be quite rational for everyone individually, depending on projected payoffs. Unlike a PD, starting positions aren't symmetrical and players' progress/payoffs are not visible to other players. So saying "just cooperate" doesn't immediately apply.
How can a state or military precommit to not having a supersecret project to develop a private AGI?
And while it's beneficial for some players to join in a cooperative effort, it may well be that a situation of several competing leagues (or really big players working alone) develops and is also stable. It's all laid over the background of existing political, religious and personal enmities and rivalries - even before we come to actual disagreements over what the AI should value.
This assumes that CEV uses something along the lines of a simulated vote as an aggregation mechanism. Currently the method of aggregation is undefined so we can't say this with confidence - certainly not as something obvious.
I agree. However, if the CEV doesn't privilege any value separately from how many people value it how much (in EV), and if the EV of a large majority values killing a small minority (whose EV is of course opposed), and if you have protection against both positive and negative utility monsters (so it's at least not obvious and automatic that the negative value of the minority would outweigh the positive value of the majority) - then my scenario seems to me to be plausible, and an explanation is necessary as to how it might be prevented.
Of course you could say that until CEV is really formally specified, and we know how the aggregation works, this explanation cannot be produced.
Absolutely, on both counts.
The majority may wish to kill the minority for wrong reasons - based on false beliefs or insufficient intelligence. In which case their CEV-s won't endorse it, and the FAI will interfere. "Fundamentally different" means their killing each other is endorsed by someone's CEV, not just by themselves.
Strong consensus of their CEV-s.
Extrapolated volition is based on objective truth, by definition.
The process of extrapolation takes this into account.
Sorry, bad formatting. I meant four independent clauses: each of the agents does not endorse CEV<other>, but endorses CEV<both>.
That's a separate problem. I think it is easier to solve than extrapolating volition or building AI.
So you're OK with the FAI not interfering if they want to kill them for the "right" reasons? Such as "if we kill them, we will benefit by dividing their resources among ourselves"?
So you're saying your version of CEV will forcibly update everyone's beliefs and values to be "factual" and disallow people to believe in anything not supported by appropriate Bayesian evidence? Even if it has to modify those people by force, the result is unlike the original in many respects that they and many other people value and see as identity-forming, etc.? And it will do this not because it's backed by a strong consensus of actual desires, but because post-modification there will be a strong consensus of people happy that the modification was made?
If your answer is "yes, it will do that", then I would not call your AI a Friendly one at all.
My understanding of the CEV doc differs from yours. It's not a precise or complete spec, and it looks like both readings can be justified.
The doc doesn't (on my reading) say that the extrapolated volition can totally conform to objective truth. The EV is based on an extrapolation of our existing volition, not of objective truth itself. One of the ways it extrapolates is by adding facts the original person was not aware of. But that doesn't mean it removes all non-truth or all beliefs that "aren't even wrong" from the original volition. If the original person effectively assigns 0 or 1 "non-updateable probability" to some belief, or honestly doesn't believe in objective reality, or believes in "subjective truth" of some kind, CEV is not necessarily going to "cure" them of it - especially not by force.
But as long as we're discussing your vision of CEV, I can only repeat what I said above - if it's going to modify people by force like this, I think it's unFriendly and if it were up to me, would not launch such an AI.
Understood. But I don't see how this partial ordering changes what I had described.
Let's say I'm A1 and you're A2. We would both prefer a mutual CEV than a CEV of the other only. But each of us would prefer even more a CEV of himself only. So each of us might try to bomb the other first if he expected to get away without retaliation. That there exists a possible compromise that is better than total defeat doesn't mean total victory wouldn't be much better than any compromise.
If you think so you must have evidence relating to how to actually solve this problem. Otherwise they'd both look equally mysterious. So, what's your idea?
I wouldn't like it. But if the alternative is, for example, to have FAI directly enforce the values of the minority on the majority (or vice versa) - the values that would make them kill in order to satisfy/prevent - then I prefer FAI not interfering.
If the resources are so scarce that dividing them is so important that even CEV-s agree on the necessity of killing, then again, I prefer humans to decide who gets them.
No. CEV does not updates anyone's beliefs. It is calculated by extrapolating values in the presence of full knowledge and sufficient intelligence.
As I said elsewhere, if a person's beliefs are THAT incompatible with truth, I'm ok with ignoring their volition. Note, that their CEV is undefined in this case. But I don't believe there exist such people (excluding totally insane).
But the total loss would be correspondingly worse. PD reasoning says you should cooperate (assuming cooperation is precommittable).
Off the top of my head, adoption of total transparency for everybody of all governmental and military matters.
The resources are not scarce at all. But, there's no consensus of CEVs. The CEVs of 80% want to kill the rest. The CEVs of 20% obviously don't want to be killed. Because there's no consensus, your version of CEV would not interfere, and the 80% would be free to kill the 20%.
I meant that the AI that implements your version of CEV would forcibly update people's actual beliefs to match what it CEV-extrapolated for them. Sorry for the confusion.
A case could be made that many millions of religious "true believers" have un-updatable 0/1 probabilities. And so on.
Your solution is to not give them a voice in the CEV at all. Which is great for the rest of us - our CEV will include some presumably reduced term for their welfare, but they don't get to vote on things. This is something I would certainly support in a FAI (regardless of CEV), just as I would support using CEV<few people + me> or even CEV<few people like me in crucial respects> to CEV<everyone>.
The only difference between us then is that I estimate there to be many such people. If you believed there were many such people, would you modify your solution, or is ignoring them however many they are fine by you?
As I said before, this reasoning is inapplicable, because this situation is nothing like a PD.
This counts as very weak evidence because it proves it's at least possible to achieve this, yes. (If all players very intensively inspect all other players to make sure a secret project isn't being hidden anywhere - they'd have to recruit a big chunk of the workforce just to watch over all the rest.)
But the probability of this happening in the real world, between all players, as they scramble to be the first to build an apocalyptic new weapon, is so small it's not even worth discussion time. (Unless you disagree, of course.) I'm not convinced by this that it's an easier problem to solve than that of building AGI or FAI or CEV.
The resources are not scarce, yet the CEV-s want to kill? Why?
It would do so only if everybody's CEV-s agree that updating these people's beliefs is a good thing.
People that would still have false factual beliefs no matter how much evidence and how much intelligence they have? They would be incurably insane. Yes, I would agree to ignore their volition, no matter how many they are.
Err. What about arguments of Douglas Hofstadter and EY, and decision theories like TDT?
This doesn't really matter for a broad range of possible payoff matrices.
Cooperating in this game would mean there is exactly one global research alliance. A cooperating move is a precommitment to abide by its rules. Enforcing such precommitment is a separate problem. Let's assume it's solved.
Maybe you're right. But IMHO it's a less interesting problem :)
Sorry for the confusion. Let's taboo "scarce" and start from scratch.
I'm talking about a scenario where - to simplify only slightly from the real world - there exist some finite (even if growing) resources such that almost everyone, no matter how much they already have, want more of. A coalition of 80% of the population forms, which would like to kill the other 20% in order to get their resources. Would the AI prevent this, althogh there is no consensus against the killing?
If you still want to ask whether the resource is "scarce", please specify what that means exactly. Maybe any finite and highly desireable resource, with returns diminishing weakly or not at all, can be considered "scarce".
As I said - this is fine by me insofar as I expect the CEV not to choose to ignore me. (Which means it's not fine through the Rawlsian veil of ignorance, but I don't care and presumably neither do you.)
The question of definition, who is to be included in the CEV? or - who is considered sane? becomes of paramount importance. Since it is not itself decided by the CEV, it is presumably hardcoded into the AI design (or evolves within that design as the AI self-modifies, but that's very dangerous without formal proofs that it won't evolve to include the "wrong" people.) The simplest way to hardcode it is to directly specify the people to be included, but you prefer testing on qualifications.
However this is realized, it would give people even more incentive to influence or stop your AI building process or to start their own to compete, since they would be afraid of not being included in the CEV used by your AI.
TDT applies where agents are "similar enough". I doubt I am similar enough to e.g. the people you labelled insane.
Which arguments of Hofstadter and Yudkowsky do you mean?
Why? What prevents several competing alliances (or single players) from forming, competing for the cooperation of the smaller players?
I have trouble thinking of a resource that would make even one person's CEV, let alone 80%, want to kill people, in order to just have more of it.
This is easy, and does not need any special hardcoding. If someone is so insane that their beliefs are totally closed and impossible to move by knowledge and intelligence, then their CEV is undefined. Thus, they are automatically excluded.
We are talking about people building FAI-s. Surely they are intelligent enough to notice the symmetry between themselves. If you say that logic and rationality makes you decide to 'defect' (=try to build FAI on your own, bomb everyone else), then logic and rationality would make everyone decide to defect. So everybody bombs everybody else, no FAI gets built, everybody loses. Instead you can 'cooperate' (=precommit to build FAI<everybody's CEV> and to bomb everyone that did not make the same precommitment). This gets us a single global alliance.
There may be a distinction between "the AI will not prevent the 80% from killing the 20%" and "nothing will prevent the 80% from killing the 20%" that is getting lost in your phrasing. I am not convinced that the math doesn't make them equivalent, in the long run - but I'm definitely not convinced otherwise.
I'm assuming the 80% are capable of killing the 20% unless the AI interferes. That's part of the thought experiment. It's not unreasonable, since they are 4 times as numerous. But if you find this problematic, suppose it's 99% killing 1% at a time. It doesn't really matter.
My point is that we currently have methods of preventing this that don't require an AI, and which do pretty well. Why do we need the AI to do it? Or more specifically, why should we reject an AI that won't, but may do other useful things?
I think you're skipping between levels hereabouts. CEV, the theoretical construct, might consider people so modified, even if a FAI based on CEV would not modify them. CEV is our values if we were better, but does not necessitate us actually getting better.
In this thread I always used CEV in the sense of an AI implementing CEV. (Sometimes you'll see descriptions of what I don't believe to be the standard interpretation of how such an AI would behave, where gRR suggests such behaviors and I reply.)
