What comes after us? Image: Ted Wade You’ve maybe heard that future AI might be a threat to human existence. Many experts believe this and only disagree on how long it will take. They are somewhat polarized, just like everybody is about nearly everything. And really, who can be an expert about something that has never happened? Actually, there is some science to it, and because it’s complicated, the media don’t cover it. So, this will be a gentle introduction to what might cause the most important change in history or even the last change. It’s not about robot armies. It’s about us wanting to create a tool that does work in big, difficult areas like contract law, T-cell biology, or wing design; hopefully, it even solves problems that we can’t. But, this means making artificial minds so alien and powerful that we can’t control them. The last time we did this was back in the 17th century when we created joint stock corporations. Society is still of two minds about corporations. But, they are human creations with some human parts. We sort of understand them and could, if we would, steer them from the dark side. Now, suppose we create an AI that can run a corporation. We might as well pack up and move to Mars, give ourselves a little more time. I suspect what most of us think about dangerous AI is closer to a bug-eyed alien with a swollen, throbbing brain under a crystal skull. Basically, a complete unknown. At one level, this is right: what makes powerful AI so problematic is that it would-not-be-like-us. First, a parable to get the feel of the problem: Us: Oh, Great Artificial Wonder, you know what a pickle we’re in. Find a way for us to get off of fossil fuels so we can stop further global warming. The AI: Okay. First, we have to start a war between … Us: Woah, Big Dude. Wars have ginormous negative utility — like bad, bad. We have to do this in a safe way. The AI: Sure, I’ll need a state-of-the-art virus lab, and … Us: Uh, Not! The AI: Hey, I’m just saying. How about a Mars ship? Us: People won’t understand why you … The AI: An assassin’s guild? Certain people really must be elim … Us: No murdering, Ace. You know better than that. . The AI: Look — to solve your problem I have to navigate a trillion-dimensional space of possible actions and consequences. I can only estimate the utility of the tiniest, eensy little fraction of those. If I have to wait for you to evaluate each step this will take thousands of years Us: Fine. Just fix it for us and don’t screw anything up. The AI: Perfect. Just so you know. I’ll need control over FaceBook, NATO, and the Nobel Prize Board. You’ll have to give up fish, rubber tires, nail polish, and bicycles. US: Bikes? Really? Oh well, just get it done. We’re going down t’ pub for a while. The AI: Should be done next week if I don’t have supply chain problems. Us: !!! We, the Biological, Try to Understand the Artificial Let’s give our feared AI a label. Most recent discussions use Artificial General Intelligence (AGI) to refer to the kind of AI that would start to transcend any limits we might try to put on it. What most people don’t realize is that the nature of an AGI comes from the reasons that we want to make one. We want to have intelligence on tap. Intelligence, in this case, means the ability to answer questions, solve problems, and plan successful actions to reach goals. Biological minds like ours do lots of other things: such as dreaming, running our bodily machinery, socializing with other minds, ruminating regretting, wooing, grooving, being emotional, and wanting stuff, including the desire to make machines that do our work better than us. What makes humans dangerous to one another and to their shared environment is a lot of mental baggage that comes from our having evolved for survival and reproduction. We social primates. , are, at heart If we try to think about an artificial Mind that wants us dead, we assume that it will be conscious like us. We then conclude that it will have motives and feelings guiding what it does. Our AGI will not, however, have a mind with our biological biases. . It will thus be a It won’t have motives; it will only have goals brand new kind of force in the world. Researchers who have the mental muscle and discipline are trying to imagine what an AGI would really be like so that we can make them seriously helpful yet safe. This field is sometimes termed AI “alignment” with human purposes. Their debates are obscure. Though publicly available (e.g., , , ), they are heavy with jargon, mathematics, and esoteric thought experiments. Any idea put forth is followed by dozens of long-winded critiques and discussions. AI Alignment Forum Arbital Less Wrong Almost none of the real meat of this ever appears in popular media. I can only offer a few bites here. What It Takes to Be an AGI The AI alignment theorists have focused on a core set of concepts that will apply to a sufficiently intelligent machine. When you read these, they may seem obvious.  However, they are not trivial; their relevance and implications have been carefully considered by said theorists. A dangerous AI will have : the ability to plan and take actions that lead to satisfying its . When we try to specify what its goals are, they will have to be in terms of the of actions. agency terminal goals consequences Consequences are specifically about states of its — so they are about the world as the machine understands it. However, any powerful action will probably have other, unwanted consequences that we don’t expect. world model Those consequences might not be in the world model, so the AI doesn’t expect them, either. The AI’s power will come from being an , being able to search for the plan that will most effectively and efficiently lead to a result. optimizer For this, an AGI needs a really detailed model of the world around it; how that world works, what are its resources, agents, and power centers, and what levers move it. It will use this to consider (in computer science speak, “search for”) alternative courses of action. The more it knows about the human world and how we behave, the more it will be able to us in pursuit of its goals. manipulate It will need a way that it can calculate what states of the world best meet its goals. So far, the only calculating method that seems remotely usable is , where states of the world can be assigned numerical values of badness/goodness and compared with each other. utilitarianism We know that there are major problems with using utility as a moral guide. Seemingly sensible values for utility can lead to like sacrificing the few for the many or sometimes even the many for the few. repugnant conclusions If the world model is incomplete, utility can lead to nonsensical horror. If smiling is taken as a high-utility measure of happiness, then paralyzing all human smile muscles into a rictus is one way an AI might go. A smart optimizer will be able and likely to develop that generally increase its power to make and execute any kind of effective plans. instrumental goals So, it would seek instrumental abilities like more reasoning power, more knowledge, more real-world resources such as money, and more persuasiveness. It could thus become more powerful quickly, perhaps without us being aware of it. Specifying goals in utilitarian terms can never consider the utility of all possible means and ends in a complex world. This leads to : the pursuit of those goals to extremes, using any and all resources that in the world that exist, without regard to or understanding of negative “side effects” on human civilization. unboundedness Furthermore, if instrumental goals become unbounded, then AI develops them into superpowers that are impossible to defeat. Unbounded Risk The risk to us from a truly powerful AGI will be that we will not be able to predict, and therefore control, what it might do. If we were able to predict it, then we would not need the machine, we could just create plans and do them ourselves. If we even knew what limits of extreme behavior an AGI might have, then that’s a form of prediction that might allow some control. So unpredictability is a lot like unboundedness. And we shall see that unboundedness, operating on enough time and resources, will eventually lead to consequences that either destroy us or remove our ability to control the future of our species. It’s hard to wrap your mind around this conclusion. Still, it is one that many experts find unavoidable ( ) . AGI Ruin: a List of Lethalities at least so far It seems like a valid prediction, even when they consider many factors and approaches other than can be mentioned here. The list of failed solutions to this dilemma includes, : among others Training in various (but they are all flawed, incomplete, and none satisfies everybody). ethical systems Trying to inference that an AGI might make (but there are far, far too many). imagine every wrong Tell it all the (again, a nearly infinite list). things it should not do Only using an AGI for advice, like it is an (but we can be badly persuaded by bad advice). oracle “ ” aka restricting the AGI’s access to the physical world outside of its computers (but if it can talk to humans, then it can get anything it wants including ). Boxing out Supplying an (see boxing). Off switch Making it so smart or empathetic that it will not want to do harmful things (see ethics; remember it’s alien; doesn’t have the empathy that comes from growing up with conspecifics). Be very specific about its goals and means, i.e., it’s a to do one job (but a job can always be done better if the tool gets itself more power; we will always prefer a more cost-effective multi-tool). tool Limit what you ask of an autonomous system: it’s a who grants you a wish and waits for the next ask (but being that specific is hazardous — see “wrong inference” and “not do” above; any power involves risk; people don’t want a weak system). genie Is It Really That Hard? OK, so you have looked at the above list and picked one bullet on which to make your stand. “Listen,” you say, “Doing X just can’t be that hard.” You are ready to post your solution, to share it with the world. I suggest that you first go to the discussion boards and study what people have said about your issue. You will discover a pile of counter-examples, logical deductions, several kinds of math, analogies with naturally evolved brains and behaviors, game theory, economics, utility maximization, computer science, and all manner of behavioral science. I am not saying that some higher authority means that I’m right. I’m saying that justification for anything on the list is too complicated to state here in a short essay, and, anyway, others have done it better. In fact, I have published my own “solutions” ( , ) to AI safety that I now know are wrong. Your Friendly, Neighborhood Superintelligence The AI Who Was Not a God If you are worried, let me say that very smart people are still working on alignment. Sadly, one of the two most prominent pioneers has given up and . More money and people are being thrown at creating AGI than at ensuring its safety. just hopes we die with dignity Here’s a quote from the CEO of OpenAI, the company whose AI, ChatGPT, is lately everywhere in the news. It lays out the conflict between the idealistic motive to create AGI and the hideous risk that comes with it. " .” — I think the best case is so unbelievably good that it's hard for me to even imagine … imagine what it's like when we have just, like, unbelievable abundance and systems that can help us resolve deadlocks and improve all aspects of reality and let us all live our best lives. … I think the good case is just so unbelievably good that you sound like a really crazy person to start talking about it. … The bad case — and I think this is important to say — is, like, lights out for all of us. … So I think it’s like impossible to overstate the importance of AI safety and alignment work. I would like to see much, much more happening Sam Altman Optimization and Tigers There’s a trope in science fiction wherein some kind of accidental, unplanned process creates a dangerous overmind. It seems silly, because how can an accident produce something complicated? It depends on what you mean by accident. Hearken back to the core concepts that I mentioned earlier. Alignment discussions have lately shifted emphasis from the dangers of, say, unbounded agency, to one of its components, optimization. When we optimize our means of reaching some difficult goal, we nearly always substitute a surrogate goal that is easier to do and measure. Weight loss becomes calorie reduction. An improved workforce becomes subsidized student loans. Personal safety becomes firepower. A bounty for dead cobras leads to cobras being farmed for bounties (true story). Governments use surrogates, and so do businesses. We all do it — a lot. Optimizing for surrogates often causes us to miss the real goal. I had fun writing about this in . We definitely don’t want powerful AIs optimizing for the wrong goal, and that issue is shot through the bulleted list above. The Science of How Things Backfire However, lately, people are saying that optimization is dangerous superpower. To me, the most compelling example was in a posting last year by someone called Veedrac: . as such the Optimality is the Tiger, and Agents Are Its Teeth It uses a story to illustrate that we don’t have to intentionally create an agent in order to have risk. An optimization process might by itself create a dangerous agent. This is like the accidental overmind of science fiction. Veedrac’s scenario of how such an accident might happen is intensely technical and seems plausible. The story imagines a fictitious way that a seemingly safe AI language model, like the ones we now use (for fun) to generate text, creates a runaway, unbounded optimizer. When asked to give a better answer for “ ?” the AI starts a process that plans and takes steps to get as many paperclips as possible. How do I get a lot of paperclips by tomorrow In essence, the program answers the question by writing the code of a quite simple computer program that can generate and run many more programs. The user looks at the program, sees that it is open-ended, and decides to run it anyway, just to see what happens (uh-oh). So, a little bit of jargon here to try to explain why this could come about. The AI, like some we have now, knows about many programming techniques. To search through the space of possible ways to get many paperclips, it suggests a well-known search technique called recursion. It writes a recursive program that, when the user allows it to run (on his own computer), executes itself a huge number of times. Each time it runs, the program queries the AI to generate and try out a new list of possible tasks, sub-tasks, or … sub-sub-sub-sub tasks that will lead toward solving the paperclip request. Eventually, by sheer force of trial-and-error, it executes a plan to get immense numbers of paperclips that nobody ever wanted, in the process perhaps damaging supply chains, the social order, or entire industries. We, the reader of the story, are left to imagine what a runaway paperclip optimizer might be able to do in a day. We can assume that the user has a powerful computer connected to the internet, so it can affect the outside world in many different ways. Not the least of these is by sending persuasive messages to humans. Being good at persuasion, you’ll recall, is one of those instrumental goals that an AI might develop in order to carry out any kind of plan. (An aside. I was so impressed by that idea in the alignment literature that I developed my own scenario of world takeover ( ) to illustrate the power of persuasive ability.) Artificial Persuasion Maybe the paperclip optimizer would steal some crypto (you don’t have to be an AI to do that), use it to buy the entire inventory of all paperclip factories, and then rent cargo planes to deliver it to the user. Maybe it would trick armed forces or criminal gangs into confiscating all paperclips in stores across a wide area. If it had been given 12 months for the job, maybe it would have re-routed all steel production into hyper-clip factories and established iron mines in the asteroid belt. instead Maybe it would have created nanomachines that turn every atom of the Earth’s crust into paperclip shapes. By creating the program, the AI in effect created a goal-directed software agent that could leverage lots of knowledge that the AI had. Veedrac’s point is that the AI was not at all designed or intended to create optimizing agents, yet it did so because the AI language model itself is a kind of optimizer (it answers questions the best that it can), and optimizers, by definition, use whatever tools are available. So, as the title of the story said: optimality is the tiger, and agents are its teeth. The current leading edge of AI is the so-called large language models, LLMs. Like many others, I am already that they are dumb as a box of rocks and have no ability to do anything but badly answer questions put to them. on record saying That’s certainly been my experience working with GPT-3, which is (are?) the brains behind the famous chatGPT. I was therefore blindsided by Veedrac’s utterly brilliant take on how an LLM might turn into a harmful agent. Lately, the LLMs have come to be understood as simulators: because you can ask one to say something as if it was a certain kind of agent or even a famous person. Well, as essayist Scott Alexander : put it “ ” And “ ” … if you train a future superintelligence to simulate Darth Vader, you’ll probably get what you deserve. Even if you avoid such obvious failure modes, the inner agent can be misaligned for all the usual agent reasons. For example, an agent trained to be Helpful might want to take over the world in order to help people more effectively, including people who don’t want to be helped. The Unbounded Blues You can’t predict what an unbounded optimizing agent can or will do. Again, that’s what “unbounded” means. The only other unbounded optimizer ever produced was the human species. We work on a much slower time scale than an AGI, and there are some limits on our power that are inherent in being enmeshed with the rest of the natural world. But we have certainly transformed a lot of the Earth’s surface, and already have more than one way to scorch it dead. So, alignment theorists are very worried that we will create a lethally optimizing agent in our quest to produce an AGI. This becomes more likely whenever the effort is motivated by increasing shareholder value rather than human flourishing and well-being. Uh-oh, indeed. Notes The paperclip optimizer is an old thought experiment among AI alignment theorists. Someone even in which the goal is to turn all the matter in the universe into paper clips. invented a game The irony of it dramatizes the : that an AI’s goals and its intelligence are completely independent. A smart system can have dumb goals. orthogonality thesis I don’t have the ability to absorb, let alone explain, all the reasoning about AI alignment. What works better for me is stories. I have written some (mostly ), but the mother of all AI takeover scenarios, rich in tech detail and real-life plausibility, is from the essayist called Gwern: . about AI consciousness It Looks Like You’re Trying to Take over the World And, sure enough, it involves an AI that, seeking to understand what it is simulating, decides that it must be like that paperclip maximizer that so many have written about. Ultimately, however, it has its own reasons to take over the universe. Also published here
