Advice for AI makers

A friend of mine is about to launch himself heavily into the realm of AI programming. The details of his approach aren't important; probabilities dictate that he is unlikely to score a major success. He's asked me for advice, however, on how to design a safe(r) AI. I've been pointing him in the right directions and sending him links to useful posts on this blog and the SIAI.

Do people here have any recommendations they'd like me to pass on? Hopefully, these may form the basis of a condensed 'warning pack' for other AI makers.

Addendum: Advice along the lines of "don't do it" is vital and good, but unlikely to be followed. Coding will nearly certainly happen; is there any way of making it less genocidally risky?

"And I heard a voice saying 'Give up! Give up!' And that really scared me 'cause it sounded like Ben Kenobi." (source)

Friendly AI is a humongous damn multi-genius-decade sized problem. The first step is to realize this, and the second step is to find some fellow geniuses and spend a decade or two solving it. If you're looking for a quick fix you're out of luck.

The same (albeit to a lesser degree) is fortunately also true of Artificial General Intelligence in general, which is why the hordes of would-be meddling dabblers haven't killed us all already.

This article (which I happened across today) written by Ben Goertzel should make interesting reading for a would-be AI maker. It details Ben's experience trying to build an AGI during the dot-com bubble. His startup company, Webmind, Inc., apparently had up to 130 (!) employees at its peak.

According to the article, the AGI was almost completed, and the main reason his effort failed was that the company ran out of money due to the bursting of the bubble. Together with the anthropic principle, this seems to imply that Ben is the person responsible for the stock market crash of 2000.

I was always puzzled why SIAI hired Ben Goertzel to be its research director, and this article only deepens the mystery. If Ben has done an Eliezer-style mind-change since writing that article, I think I've missed it.

ETA: Apparently Ben has recently been helping his friend Hugo de Garis build an AI at Xiamen University under a grant from the Chinese government. How do you convince someone to give up building an AGI when your own research director is essentially helping the Chinese government build one?

Ben has a Phd, can program, has written books on the subject and has some credibility. Those kinds of things can help a little if you are trying to get people to give you money in the hope of you building a superintelligent machine. For more see here:

It has similarly been a general rule with the Singularity Institute that, whatever it is we're supposed to do to be more credible, when we actually do it, nothing much changes. "Do you do any sort of code development? I'm not interested in supporting an organization that doesn't develop code" -> OpenCog -> nothing changes. "Eliezer Yudkowsky lacks academic credentials" -> Professor Ben Goertzel installed as Director of Research -> nothing changes. The one thing that actually has seemed to raise credibility, is famous people associating with the organization, like Peter Thiel funding us, or Ray Kurzweil on the Board.

I just came across an old post of mine that asked a similar question:

BTW, I still remember the arguments between Eliezer and Ben about Friendliness and Novamente. As late as January 2005, Eliezer wrote:

And if Novamente should ever cross the finish line, we all die. That is what I believe or I would be working for Ben this instant.

I'm curious how that debate was resolved?

From the reluctance of anyone at SIAI to answer this question, I conclude that Ben Goertzel being the Director of Research probably represents the outcome of some internal power struggle/compromise at SIAI, whose terms of resolution included the details of the conflict being kept secret.

What is the right thing to do here? Should we try to force an answer out of SIAI, for example by publicly accusing it of not taking existential risk seriously? That would almost certainly hurt SIAI as a whole, but might strengthen "our" side of this conflict. Does anyone have other suggestions for how to push SIAI in a direction that we would prefer?

There is one 'mostly harmless' for people who you think will fail at AGI. There is an entirely different 'mostly harmless' for actually have a research director who tries to make AIs that could kill us all. Why would I not think the SIAI is itself an existential risk if the criteria for director recruitment is so lax? Being absolutely terrified of disaster is the kind of thing that helps ensure appropriate mechanisms to prevent defection are kept in place.

Does this suggest that founding a stealth AGI institute (to coordinate conferences, and communication between researchers) might be suited to oversee and influence potential undertakings that could lead to imminent high-risk situations?

If you think anthropics has saved us from AI many times, you ought to believe we will likely die soon, because anthropics doesn't constrain the future, only the past. Each passing year without catastrophe should weaken your faith in the anthropic explanation.

The first sentence seems obviously true to me, the second probably false.

My reasoning: to make observations and update on them, I must continue to exist. Hence I expect to make the same observations & updates whether or not the anthropic explanation is true (because I won't exist to observe and update on AI extinction if it occurs), so observing a "passing year without catastrophe" actually has a likelihood ratio of one, and is not Bayesian evidence for or against the anthropic explanation.

Methinks that is still a lack of understanding, or a disagreement on utility calculations. I myself would rate the universes where I die as lower utility still than those were I get injured (indeed the lowest possible utility).

Better still if in all the universes I don't die.

comment by DefectiveAlgorithm · 2014-06-29T02:47:36.858Z · score: 0 (0 votes) · LW · GW

I do think 'a disagreement on utility calculations' may indeed be a big part of it. Are you a total utilitarian? I'm not. A big part of that comes from the fact that I don't consider two copies of myself to be intrinsically more valuable than one - perhaps instrumentally valuable, if those copies can interact, sync their experiences and cooperate, but that's another matter. With experience-syncing, I am mostly indifferent to the number of copies of myself to exist (leaving aside potential instrumental benefits), but without it I evaluate decreasing utility as the number of copies increases, as I assign zero terminal value to multiplicity but positive terminal value to the uniqueness of my identity.

My brand of utilitarianism is informed substantially by these preferences. I adhere to neither average nor total utilitarianism, but I lean closer to average. Whilst I would be against the use of force to turn a population of 10 with X utility each into a population of 3 with (X + 1) utility each, I would in isolation consider the latter preferable to the former (there is no inconsistency here - my utility function simply admits information about the past).

You can't appeal to common sense. That's the point of quantum immortality, it defies our common sense notions about death. Obviously, since we are used to assuming single-threaded universe, where death is equivalent to ceasing to exist.

Of course, if you kill someone, you still cause that person pain in the vast majority of universes, as well as grieving to their family and friends.

If star-trek-style teleportation was possible by creating a clone and deleting the original, is that equivalent to suicide/murder/death? If you could upload your mind to a computer but destroy your biological brain, is that suicide, and is the upload really you? Does destroying copies really matter as long as one lives on (assuming the copies don't suffer)?

You absolutely appeal to common sense on moral issues. Morality is applied common sense, in the Minsky view of "common sense" being an assortment of deductions and inferences extracted from the tangled web of my personal experiential and computational history. Morality is the result of applying that common sense knowledgebase against possible actions in a planning algorithm.

Quantum "immortality" involves a sudden, unexpected, and unjustified redefinition of "death." That argument works if you buy the premise. But, I don't.

If you are saying that there is no difference between painlessly, instantaneously killing someone in one branch while letting them live another, verses letting that person live in both, then I don't know how to proceed. If you're going to say that then you might as well make yourself indifferent to the arrow of time as well, in which case it doesn't matter if that person dies in all branches because he still "exists" in history.

Now I no longer know what we are talking about. According to my morality, it is wrong to kill someone. The existence of other branches where that person does not die does not have even epsilon difference on my evaluation of moral choices in this world. The argument from the other side seems inconsistent to me.

And yes, star trek transporters and destructive uploaders are death machines, a position I've previously articulated on lesswrong.

For useful-tool AI, learn stuff from statistics and machine learning before making any further moves.

For self-improving AI, just don't do it as AI, FAI is not quite an AI problem, and anyway most techniques associated with "AI" don't work for FAI. Instead, learn fundamental math and computer science, to a good level -- that's my current best in-a-few-words advice for would-be FAI researchers.

Isn't every AI potentially a self-improving AI? All it takes is for the AI to come upon the insight "hey, I can build an AI to do my job better."

I'm very much out of touch with the AI scene, but I believe the key distinction is between Artificial General Intelligence, versus specialized approaches like chess-playing programs or systems that drive cars.

A chess program's goal structure is strictly restricted to playing chess, but any AI with the ability to formulate arbitrary sub-goals could potentially stumble on self-improvement as a sub-goal.

Additionally, the actions that a chess AI can consider and take are limited to moving pieces on a virtual chess board, and the consequences of such actions that it considers are limited to the state of the chess game, with no model of how the outside world affects the opposing moves other than the abstract assumption that the opponent will make the best move available. The chess AI simply does not have any awareness of anything outside the chess game.

A good chess AI would not be so constrained. A history of all chess games played by the particular opponent would be quite useful. As would his psychology

Is it worth me examining the tree beyond this particular move further? How long will it take me (metacognitive awareness...) relative to my time limit?

Today's specialized AIs have little chance of becoming self-improving, but as as specialized AIs adopt more advanced techniques (like the ones Nesov suggested), the line between specialized AIs and AGIs won't be so clear. After all, chess-playing and car-driving programs can always be implemented as AGIs with very specific and limited super-goals, so I expect that as AGI techniques advance, people working on specialized AIs will also adopt them, but perhaps without giving as much thought about the AI-foom problem.

I would think that specialization reduces the variant trees that the AI has to consider which makes it unlikely that implenting AGI techniques would help the chess playing program.

It is not clear to me that the AGI wouldn't (eventually) be able to do everything that a specialised program would (and more). After all, humans are a general intelligence and can specialise; some of us are great chess players, and if we stretch the word specialise, creating a chess AI also counts (it's a human effort to create a better optimisation process for winning chess).

So I imagine an AGI, able to rewrite its own code, would at the same time be able to develop the techniques of specialised AIs, while considering broader issues that might also be of use (like taking over the world/lightcone to get more processing power for playing chess). Just like humanity making chess machines, it could discover and implement better techniques (and if it breaks out of the box, hardware), something the chess programs themselves cannot do.

Or maybe I'm nuts. /layman ignoramus disclaimer/ but in that case I'd appreciate a hint at the error I'm making (besides being a layman ignoramus). :)

EDIT: scary idea, but an AGI with the goal of becoming better at chess might only not kill us because chess is perhaps a problem that's generally soluble with finite resources.

Yay, that really helped!

Roko and I don't see eye to eye on this issue. From my POV, we have had 50 years of unsuccessful attempts. That is not exactly "getting it right the first time".

Google was not the first search engine, Microsoft was not the first OS maker - and Diffie–Hellman didn't invent public key crypto.

Being first does not necessarily make players uncatchable - and there's a selection process at work in the mean time, that weeds out certain classes of failures.

From my perspective, this is mainly a SIAI confusion. Because their funding is all oriented around the prospect of them saving the world from imminent danger, the execution of their mission apparently involves exaggerating the risks associated with that - which has the effect of stimulating funding from those who they convince that DOOM is imminent - and that the SIAI can help with averting in.

Humans will most likely get the machines they want - because people will build them to sell them - and because people won't buy bad machines.

Tim, I think that what worries me is the "detailed reliable inheritance from human morals and meta-morals" bit. The worry that there will not be "detailed reliable inheritance from human morals and meta-morals" is robust to what specific way you think the future will go. Ems can break the inheritance. The first, second or fifteenth AGI system can break it. Intelligence enhancement gone wrong can break it. Any super-human "power" that doesn't explicitly preserve it will break it.

All the examples you cite differ in the substantive dimension: the failure of attempt number 1 doesn't preclude the success of attempt number two.

In the case of the future of humanity, the first failure to pass the physical representation of human morals and metamorals on to the next timeslice of the universe is game over.

The other thing to say is that there's an important sense in which most modern creatures don't value anything - except for their genetic heritage - which all living things necessarily value.

Contrast with a gold-atom maximiser. That values collections of pure gold atoms. It cares about something besides the survival of its genes (which obviously it also cares about - no genes, no gold). It strives to leave something of value behind.

Most modern organisms don't leave anything behind - except for things that are inherited - genes and memes. Nothing that they expect to last for long, anyway. They keep dissipating energy gradients until everything is obliterated in high-entropy soup.

Those values are not very difficult to preserve - they are the default state.

If ecosystems cared about creating some sort of low-entropy state somewhere, then that property would take some effort to preserve (since it is vulnerable to invasion by creatures who use that low-entropy state as fuel). However, with the current situation, there aren't really any values to preserve - except for those of the replicators concerned.

The idea has been called variously: goal system zero, god's utility function, Shiva's values.

Even the individual replicators aren't really valued in themselves - except by themselves. There's a parliament of genes, and any gene is expendable, on a majority vote. Genes are only potentially immortal. Over time, the representation of the original genes drops. Modern refactoring techniques will mean it will drop faster. There is not really a floor to the process - eventually, all may go.

I figure a fair amount of modern heritable information (such as morals) will not be lost. Civilization seems to be getting better at keeping and passing on records. You pretty-much have to hypothesize a breakdown of civilization for much of genuine value to be lost - an unprecedented and unlikely phenomenon.

However, I expect increasing amounts of it to be preserved mostly in history books and museums as time passes. Over time, that will probably include most DNA-based creatures - including humans.

Evolution is rather like a rope. Just as no strand in a rope goes from one end to the other, most genes don't tend to do that either. That doesn't mean the rope is weak, or that future creatures are not - partly - our descendants.

If you were an intelligence only cared about the number of paperclips in the universe, you would not build a museum to the past, because you could make more paperclips with the resources needed to create such a museum.

This is not some clever, convoluted argument. This is the same as saying that if you make your computer execute

10: GOTO 20

20: GOTO 10

then it won't at any point realize the program is "stupid" and stop looping. You could even give the computer another program which is capable of proving that the first one is an infinite loop, but it won't care, because its goal is to execute the first program.

That's a different question - and one which is poorly specified:

If insufficient look-ahead is used, such an agent won't bother to remember its history - prefering instead the gratification of instant paperclips.

On the other hand, if you set the look-ahead further out, it will. That's because most intelligent agents are motivated to remember the past - since only by remembering the past can they predict the future.

Understanding the history of their own evolution may well help them to understand the possible forms of aliens - which might well help them avoid being obliterated by alien races (along with all the paper clips they have made so far). Important stuff - and well worth building a few museums over.

Remebering the past is thus actually an proximate goal for a wide range of agents. If you want to argue paperclip-loving agents won't build museums, you need to be much more specific about which paperclip-loving agents you are talking about - because some of them will.

Once you understand this you should be able to see what nonsense the "value is fragile" post is.

This has nothing to do with anthropomorphism or optimism - it is a common drive for intelligent agents to make records of their pasts - so that they can predict the consequences of their actions in the future.

Once information is lost, it is gone for good. If information might be valuable in the future, a wide range of agents will want to preserve it - to help them attain their future goals. These points do not seem particularly complicated.

I hope at least that you now realise that your "loop" analogy was wrong. You can't just argue that paperclipping agents will not have preserving the past in museums as a proximate goal - since their ultimate goal involves making paperclips. There is a clear mechanism by which preserving their past in museums might help them attain that goal in the long term.

A wide class of paperclipping agents who are not suffering from temporal myopia should attempt to conquer the universe before wasting precious time and resources with making any paperclips. Once the universe is securely in their hands - then they can get on with making paperclips. Otherwise they run a considerable risk of aliens - who have not been so distracted with useless trivia - eating them, and their paperclips. They will realise that they are in an alien race - and so they will run.

That is something we worry about from time to time, but in this case I think the downvotes are justified. Tim Tyler has been repeating a particular form of techno-optimism for quite a while, which is fine; it's good to have contrarians around.

However, in the current thread, I don't think he's taking the critique seriously enough. It's been pointed out that he's essentially searching for reasons that even a Paperclipper would preserve everything of value to us, rather than just putting himself in Clippy's place and really asking for the most efficient way to maximize paperclips. (In particular, preserving the fine details of a civilization, let alone actual minds from it, is really too wasteful if your goal is to be prepared for a wide array of possible alien species.)

I feel (and apparently, so do others) that he's just replying with more arguments of the same kind as the ones we generally criticize, rather than finding other types of arguments or providing a case why anthropomorphic optimism doesn't apply here.

We do, in fact, have detailed information about how much our own civilisation is prepared to spend on preserving its own history. We preserve many things which are millions of years old - and which take up far more resources than a human. For example, see how this museum dinosaur dwarfs the humans in the foreground. We have many such exhibits - and we are still a planet-bound civilisation. Our descendants seem likely to have access to much greater resources - and so may devote a larger quantity of absolute resources to museums.

So: that's the basis of my estimate. What is the basis of your estimate?

The real dichotomy here is "maximising evaluation function" versus "maximising probability of positive evaluation function"

In paperclip making, or better, the game of Othello/Reversi, there are choices like this:

80% chance of winning 60-0, versus 90% chance of winning 33-31.

The first maximises the winning, and is similar to a paperclip maker consuming the entire universe. The second maximises the probability of succeeding, and is similar to a paperclip maker avoiding being annihilated by aliens or other unknown forces.

Mathematically, the first is similar to finding the shortest program in Kolmogorov Complexity, while the second is similar to integrating over programs.

So, friendly AI is surely of the second kind, while insane AI is of the first kind.

There are too many fake rationalists here. The absence of any real arguments either way to my article above, is evidence of this.

My Othello/Reversi example above was easy to understand, and a very central problem in AI systems, so it should be of interest to real rationalists interested in AI, but there is only negative reaction instead, from people I guess have not even made a decent game playing AI, but nevertheless have strong opinions on how they must be.

So, for getting intelligent rational arguments on AI, this community is useless, as opposed to Yudkowsky, Schmidhuber, Hansen, Tyler, etc. which has shown on their own sites that they have something to contribute.

To get real results in AI and rationality, I do my own math and science.

Your Othello Reversi example is fundamentally flawed, but it may not seem like it unless you realize that at LW the tradition is to say that utility is linear in paperclips to Clippy. That may be our fault, but there's your explanation. "Winning 60-0", to us using our jargon, is equivalent to one paperclip, not 60. And "winning 33-31" is also equivalent to one paperclip, not 33. (or they're both equivalent to x paperclips, whatever)

So when I read your example, I read it as "80% chance of 1 paperclip, or 90% chance of 1 paperclip".

I'm sure it's very irritating to have your statement miscommunicated because of a jargon difference (paperclip = utility rather than f(paperclip) = utility)! I encourage you to post anyway, and begin with the assumption that we misunderstand you rather than the assumption that we are "fake rationalists", but realize that in the current environment (unfortunately or not, but there it is) the burden of communication is on the poster.

'Museum' and 'library' both imply, to me at least, that the data is being made available to people who might be interested in it. In the case of a paperclipper, that seems rather unlikely - why would it keep us around, instead of turning the planet into an uninhabitable supercomputer that can more quickly consider complex paperclip-maximization strategies? The information about what we were like might still exist, but probably in the form of the paperclipper's 'personal memory' - and more likely than not, it'd be tagged as 'exploitable weaknesses of squishy things' rather than 'good patterns to reproduce', which isn't very useful to us, to say the least.

I see. We have different connotations of the word, then. For me, a museum is just a place where objects of historical interest are stored.

When I talked about humans being "preserved mostly in history books and museums" - I was intending to conjour up an institution somewhat like the Jurassic park theme park. Or perhaps - looking further out - something like The Matrix. Not quite like the museum of natural history as it is today - but more like what it will turn into.

Regarding the utility of existence in a museum - it may be quite a bit better than not existing at all.

Regarding the reason for keeping objects of historical around - that is for much the same reason as we do today - to learn from them, and to preserve them for future generations to study. They may have better tools for analysing things with in the future. If the objects of study are destroyed, future tools will not be able to access them.

Disagreeing with majorities is often a bad sign. Delusional individuals may create "green ink" explanations of why others are foolish enough to disagree with them. However, critics may also find themselves disagreeing with majorities - for example when in the company of the associates of those being criticised. That is fairly often my role here. I am someone not in the thrall of the prevailing reality distortion field. Under those circumstances disagreements do not have the same significance.

Yes. To me it seems like all arguments for the importance of friendly AI are based on the assumption that its moral evaluation function must be correct, or it will necessarily become evil or insane, due over optimization of some weird aspect.

However, with uncertainty in the system, as limited knowledge of the past, or as uncertainty in what the evaluation function is, optimization should take this into account, and make strategies to keep its options open. In the paperclip example, this would be avoiding making people into paperclips because it suspects that the paperclips might be for people.

Mathematically, an AI going evil insane corresponds to it seeking the most probable optimization, while doing multiple strategies corresponds to it integrating the probabilities over different outcomes.

If you want to design a complex malleable AI design and have some guarantees about what it will do (rather than just fail in some creative way), think of simple properties you can prove about your code, and then try and prove them using Coq or other theorem proving system.

For solving the Friendly AI problem, I suggest the following constraints for your initial hardware system:

1.) All outside input (and input libraries) are explicitly user selected. 2.) No means for the system to establish physical action (e.g., no robotic arms.) 3.) No means for the system to establish unexpected communication (e.g., no radio transmitters.)

Once this closed system has reached a suitable level of AI, then the problem of making it friendly can be worked on much easier and more practically, and without risk of the world ending.

To start out from the beginning to make a GAI friendly through some other means seems rather ambitious to me. Why not just work on AI now, make sure when you're getting close to the goal, that the AI is suitably restricted, and then finally use the AI itself as an experimental testbed for "personality certification".

Vladimir and orthonormal,

Please point me to some more details about the AI box experiment, since I think what i suggested earlier as isolated virtual worlds is pretty much the same as what zero call is suggesting here.

I feel that there are huge assumptions in the present AI Box experiment. The gatekeeper and the AI share a language, for one, by which the AI convinces the gatekeeper.

If AGI is your only criteria without regards to friendliness, just make sure not to communicate with the AI. Turing tests are not the only proofs of intelligence. If the agi can come up with unique solutions in the universe in which it is isolated, that is enough to understand this algorithm is creative.

This just evoked a possibly-useful thought:

If observing but not communicating with a boxed AI does a good enough job of patching the security holes (which I understand that it might not - that's for someone who better understands the issue to look at), perhaps putting an instance of a potential FAI in a contained virtual world would be useful as a test. It seems to me that a FAI that didn't have humans to start with would perhaps have to invent us, or something like us in some specific observable way(s), because of its values.

Due to the lack of details, it is difficult to make a recomendation, but some thoughts.

Both as an AGI challenge and for general human safety, business intelligence datawarehouses are probably a good bet. Any pattern undetected by humans detected by an AI could mean good money, which could feedback into more resources for the AI. Also, the ability of corporations to harm others doesn't increase significantly with a better business intelligence tool.

Virtual worlds - If the AI is tested in an isolated virtual world, that will be better for us. Test it in a virtual world that is completely unlike ours, a gas giant simulation maybe. Even if it develops extremely capable technology to deal with the gas giant environment within the simulation, it would mean very little in the real world except as a demonstration of intelligence.

Virtual Worlds doesn't buy you any safety, even if it can't break out of the simulator.

If you manage to make AI, you've got a Really Powerful Optimization Process. If it worked out simulated physics and has access to it's own source, it's probably smart enough to 'foom', even with the simulation. At which point you have a REALLY powerful optimizer, and no idea how to prove anything about it's goal system. An untrustable genie.

You are giving a budding superintelligence exposure to a simulation based on our physics? It would work out the physics of the isolated virtual world, deduce from the traces you leave in the design that it is in a simulation and have a good guess on what we believe to be the actual physics of our universe.

My point with the virtual worlds was to put the AI into a simulation sufficiently unlike our world that it wouldn't be a threat and sufficiently like our world that we would be able to recognise what it does as intelligence. Hence the Gas giant example.

If we were to release an AI into today's simulations like sims which are much less granular than the one I have proposed in my post, then it would figure out that it is in a simulation much faster.

If we put it into some other kind of universe with weird physics, a magical universe lets say, then we will need to send someone intelligent to do a considerable amount of trials before we release the AI. This is to prove that whatever solutions the AI comes up with are genuinely intelligent and not something that is obvious.

I too agree that we wouldn't want to bet our existence on it being unable to get out of that box, but what evidence will we leave in the simulation which will point to it that it has to "Press Red for talking to simulator"?

That is odd; I distinctly recall posting this before the top-level.

There isn't really a general answer to "how to design a safe AI". It really depends what the AI is used for (and what they mean by AI).

For recursively self-improving AI, you've got your choice of "it's always bad", "You should only do it the SIAI way (and they haven't figured that out yet)", or "It's not a big deal, just use sofware best practices and iterate".

For robots, I've argued in the past that robots need to share our values in order to avoid squashing them, but I haven't seen anyone work this out rigorously. On a different tack altogether, Ron Arkin's Governing Lethal Behavior in Autonomous Robots is excellent and describes in detail how to make military robots that use lethality appropriately. In a household application, it's very difficult to see what sorts of actions might be problematic, but in a military application the main concern is making "aim the gun and fire" only happen when you really want it to.

For video games and the like, there's plenty of literature about the question, but not much to take seriously there.

I've read through the AI-Box experiment, and I can still say that I recommend the "sealed AI" tactic. The Box experiment isn't very convincing at all to me, which I could go into detail about, but that would require a whole post. But of course, I'll never develop the karma to do that because apparently the rate at which I ask questions of proper material exceeds the rate at which I post warm, fuzzy comments. Well, at least I have my own blog...

It looks like you're picking up karma relatively rapidly of late; it takes a while to learn the ways of speaking around here that don't detract from the content of one's comments, but once that happens, most people will accumulate karma reasonably quickly.

But since the AI-Box experiment has been discussed a bit here already, it might make sense to lay out your counterargument here or on the Open Thread for now. I know that's not as satisfying as making a post, but I think you'll still get quality discussion.

(Also, a top-level post on an old topic by a relative newcomer runs a risk of getting downvoted for redundancy if the argument recapitulates someone's old position— and post downvotes can kill your karma for a while. Caveat scriptor!)

P.S. Also on the topic, and quite interesting: That Alien Message.

My current toy thinking along these lines is imagining a program that will write a program to solve the towers of hanoi, given only some description of the problem, and do nothing else, using only fixed computational resources for the whole thing.

I think that's safe, and would illustrate useful principles for FAI.

An earlier comment of mine on the Towers of Hanoi. (ETA: I mean earlier relative to the point in time when this thread was resurrected.)

Are you familiar with Hofstadter's work in "microdomains", such as Copycat et al.?

More like a program that takes

What Blueberry said. The page you linked just gives the standard program for solving Towers of Hanoi. What JamesAndrix was imagining was a program that comes up with that solution, given just the description of the problem -- i.e., what the human coder did.

Well, this can actually be done (yes, in Prolog with a few metaprogramming tricks), and it's not really that hard - only very inefficient, i.e. feasible only for relatively small problems. See: Inductive logic programming.

No, not learning. And the 'do nothing else' parts can't be left out.

This shouldn't be a general automatic programing method, just something that goes through the motions of solving this one problem. It should already 'know' whatever principles lead to that solution. The outcome should be obvious to the programmer, and I suspect realistically hand-traceable. My goal is a solid understanding of a toy program exactly one meta-level above hanoi.

This does seem like something Prolog could do well, if there is already a static program that does this I'd love to see it.

Until you specify the format of a description of the problem, and how the program figures out how to write a program to solve the problem, it is hard to tell if this would be safe.

And if you don't know that it is safe, it isn't. Using some barrier like "fixed computational resources" to contain a non-understood process is a red flag.

The format of the description is something I'm struggling with, but I'm not clear how it impacts safety.

How the AI figures things out is up to the human programmer. Part of my intent in this exercise is to constrain the human to solutions they fully understand. In my mind my original description would have ruled out evolving neural nets, but now I see I definitely didn't make that clear.

By 'fixed computational resources' I mean that you've got to write the program such that if it discovers some flaw that gives it access to the internet, it will patch around that access because what it is trying to do is solve the puzzle of (solving the puzzle using only these instructions and these rules and this memory.)

What I'm looking for is a way to work on friendliness using goals that are much simpler than human morality, implemented by minds that are at least comprehensible in their operation, if not outright step-able.

Try to build an AI that:

  1. Implements a timeless decision theory.
  2. Is able to value things that it does not directly perceive, and in particular cares about other universes.
  3. Has a utility function such that additional resources have diminishing marginal returns.

Such an AI is more likely to participate in trades across universes, possibly with a friendly AI that requests our survival.

[EDIT]: It now occurs to me that an AI that participates in inter-universal trade would also participate in inter-universal terrorism, so I'm no longer confident that my suggestions above are good ones.

(Disclaimer: I don't know anything about AI.)

Is the marginal utility of resources something that you can input? It seems to me that since resources have instrumental value (pretty much, that's what a resource is by definition), their value would be something that has to be outputted by the utility function.

If you tried to input the value of resources, you'd run into difficulties with the meaning of resources. For example, would the AI distinguish "having resources" from "having access to resources" from "having access to the power of having access to resources"? Even if 'having resources' has negative utility for the AI, he might enjoy controlling resources in all kinds of ways in exchange for power to satisfy terminal values.

Even if you define power as a type of resource, and give that negative utility, then you will basically be telling the AI to enjoy not being able to satisfy his terminal values. (But yet, put that way, it does suggest some kind of friendly passive/pacifist philosophy.)

There is a difference between giving something negative utility and giving it decreasing marginal utility. It's sufficient to give the AI exponents strictly between zero and one for all terms in a positive polynomial utility function, for instance. That would be effectively "inputting" the marginal utility of resources, given any current state of the world.

There is a difference between giving something negative utility and giving it decreasing marginal utility.

I was considering the least convenient argument, the one that I imagined would result in the least aggressive AI. (I should explain here that I considered that even a 0 terminal utility for the resource itself would not result in 0 utility for that resource, because that resource would have some instrumental value in achieving things of value.)

(Above edited because I don't think I was understood.)

But I think the problem in logic identified with inputting the value of an instrumental value remains either way.

You pretty much have to guess about the marginal value of resources. But let's say the AI's utility function is "10^10th root of # of paperclips in universe." Then it probably satisfies the criterion.

EDIT: even better would be U = 1 if the universe contains at least one paperclip, otherwise 0.

Can you please elaborate on "trades across universes"? Do you mean something like quantum civilization suicide, as in Nick Bostrom's paper on that topic?

Here's Nesov's elaboration of his trading across possible worlds idea.

Personally, I think it's an interesting idea, but I'm skeptical that it can really work, except maybe in very limited circumstances such as when the trading partners are nearly identical.

What does "AI programming" even mean ? If he's trying to make some sort of an abstract generally-intelligent AI, then he'll be wasting his time, since the probability of him succeeding is somewhere around epsilon. If he's trying to make an AI for some specific purpose, then I'd advise him to employ lots of testing and especially cross-validation, to avoid overfitting. Of course, if his purpose is something like "make the smartest killer drone ever", then I'd prefer him to fail...
