"I wish to live in the locations of my choice, in a physically healthy, uninjured, and apparently normal version of my current body containing my current mental state, a body which will heal from all injuries at a rate three sigmas faster than the average given the medical technology available to me, and which will be protected from any diseases, injuries or illnesses causing disability, pain, or degraded functionality or any sense, organ, or bodily function for more than ten days consecutively or fifteen days in any year..."
-- The Open-Source Wish Project, Wish For Immortality 1.1
There are three kinds of genies: Genies to whom you can safely say "I wish for you to do what I should wish for"; genies for which no wish is safe; and genies that aren't very powerful or intelligent.
Suppose your aged mother is trapped in a burning building, and it so happens that you're in a wheelchair; you can't rush in yourself. You could cry, "Get my mother out of that building!" but there would be no one to hear.
Luckily you have, in your pocket, an Outcome Pump. This handy device squeezes the flow of time, pouring probability into some outcomes, draining it from others.
The Outcome Pump is not sentient. It contains a tiny time machine, which resets time unless a specified outcome occurs. For example, if you hooked up the Outcome Pump's sensors to a coin, and specified that the time machine should keep resetting until it sees the coin come up heads, and then you actually flipped the coin, you would see the coin come up heads. (The physicists say that any future in which a "reset" occurs is inconsistent, and therefore never happens in the first place - so you aren't actually killing any versions of yourself.)
Whatever proposition you can manage to input into the Outcome Pump, somehow happens, though not in a way that violates the laws of physics. If you try to input a proposition that's too unlikely, the time machine will suffer a spontaneous mechanical failure before that outcome ever occurs.
You can also redirect probability flow in more quantitative ways using the "future function" to scale the temporal reset probability for different outcomes. If the temporal reset probability is 99% when the coin comes up heads, and 1% when the coin comes up tails, the odds will go from 1:1 to 99:1 in favor of tails. If you had a mysterious machine that spit out money, and you wanted to maximize the amount of money spit out, you would use reset probabilities that diminished as the amount of money increased. For example, spitting out $10 might have a 99.999999% reset probability, and spitting out $100 might have a 99.99999% reset probability. This way you can get an outcome that tends to be as high as possible in the future function, even when you don't know the best attainable maximum.
So you desperately yank the Outcome Pump from your pocket - your mother is still trapped in the burning building, remember? - and try to describe your goal: get your mother out of the building!
The user interface doesn't take English inputs. The Outcome Pump isn't sentient, remember? But it does have 3D scanners for the near vicinity, and built-in utilities for pattern matching. So you hold up a photo of your mother's head and shoulders; match on the photo; use object contiguity to select your mother's whole body (not just her head and shoulders); and define the future function using your mother's distance from the building's center. The further she gets from the building's center, the less the time machine's reset probability.
You cry "Get my mother out of the building!", for luck, and press Enter.
For a moment it seems like nothing happens. You look around, waiting for the fire truck to pull up, and rescuers to arrive - or even just a strong, fast runner to haul your mother out of the building -
BOOM! With a thundering roar, the gas main under the building explodes. As the structure comes apart, in what seems like slow motion, you glimpse your mother's shattered body being hurled high into the air, traveling fast, rapidly increasing its distance from the former center of the building.
On the side of the Outcome Pump is an Emergency Regret Button. All future functions are automatically defined with a huge negative value for the Regret Button being pressed - a temporal reset probability of nearly 1 - so that the Outcome Pump is extremely unlikely to do anything which upsets the user enough to make them press the Regret Button. You can't ever remember pressing it. But you've barely started to reach for the Regret Button (and what good will it do now?) when a flaming wooden beam drops out of the sky and smashes you flat.
Which wasn't really what you wanted, but scores very high in the defined future function...
The Outcome Pump is a genie of the second class. No wish is safe.
If someone asked you to get their poor aged mother out of a burning building, you might help, or you might pretend not to hear. But it wouldn't even occur to you to explode the building. "Get my mother out of the building" sounds like a much safer wish than it really is, because you don't even consider the plans that you assign extreme negative values.
Consider again the Tragedy of Group Selectionism: Some early biologists asserted that group selection for low subpopulation sizes would produce individual restraint in breeding; and yet actually enforcing group selection in the laboratory produced cannibalism, especially of immature females. It's obvious in hindsight that, given strong selection for small subpopulation sizes, cannibals will outreproduce individuals who voluntarily forego reproductive opportunities. But eating little girls is such an un-aesthetic solution that Wynne-Edwards, Allee, Brereton, and the other group-selectionists simply didn't think of it. They only saw the solutions they would have used themselves.
Suppose you try to patch the future function by specifying that the Outcome Pump should not explode the building: outcomes in which the building materials are distributed over too much volume, will have ~1 temporal reset probabilities.
So your mother falls out of a second-story window and breaks her neck. The Outcome Pump took a different path through time that still ended up with your mother outside the building, and it still wasn't what you wanted, and it still wasn't a solution that would occur to a human rescuer.
If only the Open-Source Wish Project had developed a Wish To Get Your Mother Out Of A Burning Building:
"I wish to move my mother (defined as the woman who shares half my genes and gave birth to me) to outside the boundaries of the building currently closest to me which is on fire; but not by exploding the building; nor by causing the walls to crumble so that the building no longer has boundaries; nor by waiting until after the building finishes burning down for a rescue worker to take out the body..."
All these special cases, the seemingly unlimited number of required patches, should remind you of the parable of Artificial Addition - programming an Arithmetic Expert Systems by explicitly adding ever more assertions like "fifteen plus fifteen equals thirty, but fifteen plus sixteen equals thirty-one instead".
How do you exclude the outcome where the building explodes and flings your mother into the sky? You look ahead, and you foresee that your mother would end up dead, and you don't want that consequence, so you try to forbid the event leading up to it.
Your brain isn't hardwired with a specific, prerecorded statement that "Blowing up a burning building containing my mother is a bad idea." And yet you're trying to prerecord that exact specific statement in the Outcome Pump's future function. So the wish is exploding, turning into a giant lookup table that records your judgment of every possible path through time.
You failed to ask for what you really wanted. You wanted your mother to go on living, but you wished for her to become more distant from the center of the building.
Except that's not all you wanted. If your mother was rescued from the building but was horribly burned, that outcome would rank lower in your preference ordering than an outcome where she was rescued safe and sound. So you not only value your mother's life, but also her health.
And you value not just her bodily health, but her state of mind. Being rescued in a fashion that traumatizes her - for example, a giant purple monster roaring up out of nowhere and seizing her - is inferior to a fireman showing up and escorting her out through a non-burning route. (Yes, we're supposed to stick with physics, but maybe a powerful enough Outcome Pump has aliens coincidentally showing up in the neighborhood at exactly that moment.) You would certainly prefer her being rescued by the monster to her being roasted alive, however.
How about a wormhole spontaneously opening and swallowing her to a desert island? Better than her being dead; but worse than her being alive, well, healthy, untraumatized, and in continual contact with you and the other members of her social network.
Would it be okay to save your mother's life at the cost of the family dog's life, if it ran to alert a fireman but then got run over by a car? Clearly yes, but it would be better ceteris paribus to avoid killing the dog. You wouldn't want to swap a human life for hers, but what about the life of a convicted murderer? Does it matter if the murderer dies trying to save her, from the goodness of his heart? How about two murderers? If the cost of your mother's life was the destruction of every extant copy, including the memories, of Bach's Little Fugue in G Minor, would that be worth it? How about if she had a terminal illness and would die anyway in eighteen months?
If your mother's foot is crushed by a burning beam, is it worthwhile to extract the rest of her? What if her head is crushed, leaving her body? What if her body is crushed, leaving only her head? What if there's a cryonics team waiting outside, ready to suspend the head? Is a frozen head a person? Is Terry Schiavo a person? How much is a chimpanzee worth?
Your brain is not infinitely complicated; there is only a finite Kolmogorov complexity / message length which suffices to describe all the judgments you would make. But just because this complexity is finite does not make it small. We value many things, and no they are not reducible to valuing happiness or valuing reproductive fitness.
There is no safe wish smaller than an entire human morality. There are too many possible paths through Time. You can't visualize all the roads that lead to the destination you give the genie. "Maximizing the distance between your mother and the center of the building" can be done even more effectively by detonating a nuclear weapon. Or, at higher levels of genie power, flinging her body out of the Solar System. Or, at higher levels of genie intelligence, doing something that neither you nor I would think of, just like a chimpanzee wouldn't think of detonating a nuclear weapon. You can't visualize all the paths through time, any more than you can program a chess-playing machine by hardcoding a move for every possible board position.
And real life is far more complicated than chess. You cannot predict, in advance, which of your values will be needed to judge the path through time that the genie takes. Especially if you wish for something longer-term or wider-range than rescuing your mother from a burning building.
I fear the Open-Source Wish Project is futile, except as an illustration of how not to think about genie problems. The only safe genie is a genie that shares all your judgment criteria, and at that point, you can just say "I wish for you to do what I should wish for." Which simply runs the genie's should function.
Indeed, it shouldn't be necessary to say anything. To be a safe fulfiller of a wish, a genie must share the same values that led you to make the wish. Otherwise the genie may not choose a path through time which leads to the destination you had in mind, or it may fail to exclude horrible side effects that would lead you to not even consider a plan in the first place. Wishes are leaky generalizations, derived from the huge but finite structure that is your entire morality; only by including this entire structure can you plug all the leaks.
With a safe genie, wishing is superfluous. Just run the genie.
Is there a safe way to wish for an unsafe genie to behave like a safe genie? That seems like a wish TOSWP should work on.
"I wish for a genie that shares all my judgment criteria" is probably the only safe way.
This might be done by picking an arbitrary genie, and then modifying your judgement criteria to match that genie's.
Sounds like we need to formalize human morality first, otherwise you aren't guaranteed consistency. Of course formalizing human morality seems like a hopeless project. Maybe we can ask an AI for help!
On further reflection, the wish as expressed by Nick Tarleton above sounds dangerous, because all human morality may either be inconsistent in some sense, or 'naive' (failing to account for important aspects of reality we aren't aware of yet). Human morality changes as our technology and understanding changes, sometimes significantly. There is no reason to believe this trend will stop. I am afraid (genuine fear, not figure of speech) that the quest to properly formalize and generalize human morality for use by a 'friendly AI' is akin to properly formalizing and generalizing Ptolemean astronomy.
This generalises. Since you don't know everything, anything you do might wind up being counterproductive.
Like, I once knew a group of young merchants who wanted their shopping district revitalised. They worked at it and got their share of federal money that was assigned to their city, and they got the lighting improved, and the landscaping, and a beautiful fountain, and so on. It took several years and most of the improvements came in the third year. Then their landlords all raised the rents and they had to move out.
That one was predictable in hindsight, b... (read more)

Obviously in reference to the line of thought in the "devil's dilemma" enshrined in the original Bedazzled, and so many magic-wish-fulfillment folk tales, in which there is always a loophole exploited by a counter-force, probably IMO in response to the motive to shortcut certain aspects of reality and its regulatory processes, known or unknown.

It seems contradictory to previous experience that humans should develop a technology with "black box" functionality, i.e. whose effects could not be foreseen and accurately controlled by the end-user. Technology has to be designed and it is designed with an effect/result in mind. It is then optimized so that the end user understands how to call forth this effect. So positing an effective equivalent of the mythological figure "Genie" in technological form ignores the optimization-for-use that would take place at each stage of developing... (read more)
Eric, I think he was merely attempting to point out the futility of wishes. Or rather, the futility of asking something for something you want that does not share your judgments on things. The Outcome pump is merely, like the Genie, a mechanism by which to explain his intended meaning. The problem of the outcome pump is, twofold: 1. Any theory that states that time is anything other than a constant now with motion and probability may work mathematically but has yet to be able to actually alter the thing which it describes in a measurable way, and 2. The pr... (read more)

You're right. Hence, CEV.
Eliezer, you read Home on the Strange?
So positing an effective equivalent of the mythological figure "Genie" in technological form ignores the optimization-for-use that would take place at each stage of developing an Outcome-Pump. The technology-falling-from-heaven which is the Outcome Pump demands that we reverse engineer the optimization of parameters which would have necessarily taken place if it had in fact developed as human technologies do.
Unfortunately, Eric, when you build a powerful enough Outcome Pump, it can wish more powerful Outcome Pumps into existence, which can in turn wish even more powerful Outcome Pumps into existence. So once you cross a certain threshold, you get an explosion of optimization power, which mere trial and error is not sufficient to control because of the enormous change of context, in particular, the genie has gone from being less powerful than you to being more powerful than you, and what appeared to work in the former context won't work in the latter.
Which is precisely what happened to natural selection when it developed humans.
"Unfortunately, Eric, when you build a powerful enough Outcome Pump, it can wish more powerful Outcome Pumps into existence, which can in turn wish even more powerful Outcome Pumps into existence."
Yes, technology that develops itself, once a certain point of sophistication is reached.
My only acquaintance with AI up to now has been this website: http://www.20q.net Which contains a neural network that has been learning for two decades or so. It can "read your mind" when you're thinking of a character from the TV show The Simpsons. Pretty incredible actually!
Eliezer, I clicked on your name in the above comment box and voila- a whole set of resources to learn about AI. I also found out why you use the adjective "unfortunately" in reference to the Outcome Pump, as its on the Singularity Institute website. Fascinating stuff!
"It seems contradictory to previous experience that humans should develop a technology with "black box" functionality, i.e. whose effects could not be foreseen and accurately controlled by the end-user."
Eric, have you ever been a computer programmer? That technology becomes more and more like a black box is not only in line with previous experience, but I dare say is a trend as technological complexity increases.
"Eric, have you ever been a computer programmer? That technology becomes more and more like a black box is not only in line with previous experience, but I dare say is a trend as technological complexity increases."
No I haven't. Could you expand on what you mean?
In the first year of law school students learn that for every clear legal rule there always exists situations for which either the rule doesn't apply or for which the rule gives a bad outcome. This is why we always need to give judges some discretion when administering the law.
James Miller, have you read The Myth of the Rule of Law? What do you think of it?
Every computer programmer, indeed anybody who uses computers extensively has been surprised by computers. Despite being deterministic, a personal computer taken as a whole (hardware, operating system, software running on top of the operating system, network protocols creating the internet, etc. etc.) is too large for a single mind to understand. We have partial theories of how computers work, but of course partial theories sometimes fail and this produces surprise.
This is not a new development. I have only a partial theory of how my car works, but in th... (read more)
TGGP,
I have not read the Myth of the Rule of Law.
Given that it's impossible for the someone to know your total mind without being it, the only safe genie is yourself.
From the above it's easy to see why it's never possible to define the "best interests" of anyone but your own self. And from that it's possible to show that it's never possible to define the best interests of the public, except through their individually chosen actions. And from that you can derive libertarianism.
Just an aside :-)
"Ultimately, most objects, man-made or not are 'black boxes.'"
OK, I see what you're getting at.
Three questions about black boxes:
1) Does the input have to be fully known/observable to constitute a black box? When investigating a population of neurons, we can give stimulus to these cells, but we cannot be sure that we are aware of all the inputs they are receiving. So we effectively do not entirely understand the input being given.
2) Does the output have to be fully known/observable to constitute a black box? When we measure the output of a popula... (read more)
TGGP: What did you think of it? I agree till the Socrates Universe, but thought the logic goes downhill from there.
tggp, that paper was interesting, although I found its thesis unremarkable. You should share it with our pal Mencius.
Upon some reflection, I remembered that Robin has showed that two Bayesians who share the same priors can't disagree. So perhaps you can get your wish from an unsafe genie by wishing, "... to run a genie that perfectly shares my goals and prior probabilities."
As long as you're wishing, wouldn't you rather have a genie whose prior probabilities correspond to reality as accurately as possible? I wouldn't pick an omnipotent but equally ignorant me to be my best possible genie.
"As long as you're wishing, wouldn't you rather have a genie whose prior probabilities correspond to reality as accurately as possible?"
Such a genie might already exist.
If the rule doesn't apply, it's not relevant in the first place. I doubt very much you can establish what a 'bad' outcome would involve in such a way that everyone would agree - and I don't see why your personal opinion on the matter should be of concern when we consider legal design.
You mean GOD? From the good book? It's more plausible than some stories I could mention.
GOD, I meta-wish for an ((...Emergence-y Re-get) Emergence-y Re-get) Emergency Regret Button.
Recovering Irrationalist said:
I wouldn't pick an omnipotent but equally ignorant me to be my best possible genie.
Right. It's silly to wish for a genie with the same beliefs as yourself, because the system consisting of you and an unsafe genie is already such a genie.
I discussed "The Myth of the Rule of Law" with Mencius Moldbug here. I recognize that politics alters the application of law and that as long as it is written in natural language there will be irresolvable differences over its meaning. At the same time I observe that different countries seem to hold different levels of respect for the "rule of law" that the state is expected to obey, and it appears to me that those more prone to do so have more livable societies. I think the norm of neutrality on the part of judges applying law with obj... (read more)

Is a genie that does share all my judgment criteria necessarily safe?

"Whatever proposition you can manage to input into the Outcome Pump, somehow happens, though not in a way that violates the laws of physics. If you try to input a proposition that's too unlikely, the time machine will suffer a spontaneous mechanical failure before that outcome ever occurs."
So, a kind of Maxwell's demon? :)
Rather than designing a genie to exactly match your moral criteria, the simple solution would be to cheat and use yourself as the genie. What the Outcome Pump should solve for is your own future satisfaction. To that end, you would omit all functionality other than the "regret button", and make the latter default-on, with activation by anything other than a satisfied-you vanishingly improbable. Say, with a lengthy password.
Of course, you could still end up in a universe where your brain has been spontaneously re-wired to hate your mother. However, I think that such an event is far less likely than a proper rescue.
You have a good point about the exhaustiveness required to ensure the best possible outcome. In that case the ability of the genie to act "safely" would depend upon the level of the genie's omniscience. For example, if the genie could predict the results of any action it took, you could simply ask it to select any path that results in you saying "thanks genie, great job" without coercion. Therefore it would effectively be using you as an oracle of success or failure.
A non-omniscient genie would either need complete instructions, or woul... (read more)
With a safe genie, wishing is superfluous. Just run the genie.
But while most genies are terminally unsafe, there is a domain of "nearly-safe" genies, which must dwarf the space of "safe" genies (examples of a nearly-safe genie: one that picks the moral code of a random living human before deciding on an action or a safe genie + noise). This might sound like semantics, but I think the search for a totally "safe" genie/AI is a pipe-dream, and we should go for "nearly safe" (I've got a short paper on one approach to this here).
I am worried that properties P1...Pk are somehow valuable.
In what sense can they be valuable, if they are not valued by human judgment criteria (even if not consciously most of the time)?
For example, if the genie could predict the results of any action it took, you could simply ask it to select any path that results in you saying "thanks genie, great job" without coercion.
Formalizing "coercion" is itself an exhaustive problem. Saying "don't manipulate my brain except through my senses" is a big first step, but it doesn't exclude, e.g., powerful arguments that you don't really want your mother to live.
Nick,
Are you thinking of magically strong arguments, or ones that convince because they provide good reasons?
I'd think the latter would be valuable even if it leads to a result you'd initially suppose to be bad.
The first.
"In what sense can [properties P1...Pk] be valuable, if they are not valued by human judgment criteria (even if not consciously most of the time)?"
I don't know. It might be that the only sense in which something can be valuable is to look valuable according to human judgment criteria (when thoroughly implemented, and well informed, and all that). If so, my concern is ill-formed or irrelevant.
On the other hand, it seems possible that human judgments of value are an imperfect approximation of what is valuable in some other (external?) sense. Im... (read more)
Nick,
What makes you think that magically strong arguments are possible? I can imagine arguments that work better than they should because they indulge someone's unconscious inclinations or biases, but not ones that work better than their truthfulness would suggest and cut against the grain of one's inclinations.
I don't know that they are, but it's the conservative assumption, in that it carries less risk of the world being destroyed if you're wrong. Also, see the AI-box experiments.
Excellent post.
Damn, it took me a long time to make the connection between the Outcome Pump and quantum suicide reality editing. And the argument that proves the unsafety of the Outcome Pump is perfectly isomorphic to the argument why quantum immortality is scary.
"I wish that the genie could understand a programming language."
Then I could program it unambiguously. I obviously wouldn't be able to program my mother out of the burning building on the spot, but at least there would be a host of other wishes I could make that the genie won't be able to screw up.
"I wish that wishes would be granted as the wisher would interpret them".
Are convicted murderers not human?
So if I specified to the Outcome Pump, that I want the outcome, where the person, that is future version of me (by DNA, and by physical continuity of the body), will write "ABRACADABRA, This outcome I good enough and I value it for $X" on the paper and put in on the outcome pump, and the $X is how much I value the outcome. And if this won't happen in one year, I don't want this outcome, either).
Are there any loopholes?
If the genie is clueless but not actively malicious, then you can ask the genie to describe how it will fulfill your wish. If it describes making the building explode and having your mother's dead body fly out, you correct the genie and tell it to try again. If it gives an inadequate description (says the building explodes and fails to mention what happens to the mother's body at all), you can ask it to elaborate. If it gives a description that is inadequate in exactly the right way to make you think it's describing it adequately while still leaving a huge loophole, there's not much you can do, but that's not a clueless genie, that's an actively malicious genie pretending to be a clueless one.
There was a story with an "outcome pump" like this, I do not remember the name. Essentially, a chemical had to get soaked with water due to some time travel related handwave. You could do minor things like getting your mom out of the building by pouring water on the chemical if you are satisfied with the outcome, with some risk that a hurricane would form instead and soak the chemical. It would produce the least improbable outcome (in the sense that all probabilities would become as if it is given that the chemical got soaked, so naturally the le... (read more)

Living things moving at high speeds or being exposed to dangerous levels of heat are bad. No living things falling long distances.
