10+ years ago I expected we would get AI that would impact blue collar work long before AI that impacted white collar work. Not sure exactly where I got the impression, but I remember some "rising tide of AI" analogy and graphic that had artists and scientists positioned on the high ground.
Recently it doesn't seem to be playing out as such. The current best LLMs I find marvelously impressive (despite their flaws), and yet... where are all the awesome robots? Why can't I buy a robot that loads my dishwasher for me?
Last year this really started to bug me, and after digging into it with some friends I think we collectively realized something that may be a hint at the answer.
As far as we know, it took roughly 100M-1B years to evolve human level "embodiment" (evolve from single celled organisms to human), but it only took around ~100k-1M for humanity to evolve language, knowledge transfer and abstract reasoning.
So it makes me wonder, is embodiment (advanced robotics) 1000x harder than LLMs from an information processing perspective?
- kushalc 1y agoNot a robotics guy, but to extent that the same fundamentals hold— I think it's a degrees of freedom question. Given the (relatively) low conditional entropy of natural language, there aren't actually that many degrees of (true) freedom. On the other hand, in the real world, there are massively more degrees of freedom both in general (3 dimensions, 6 degrees of movement per joint, M joints, continuous vs. discrete space, etc.) and also given the path dependence of actions, the non-standardized nature of actuators, actuators, kinematics, etc. All in, you get crushed by the curse of dimensionality. Given N degrees of true freedom, you need O(exp(N)) data points to achieve the same performance. Folks do a bunch of clever things to address that dimensionality explosion, but I think the overly reductionist point still stands: although the real world is theoretically verifiable (and theoretically could produce infinite data), in practice we currently have exponentially less real-world data for an exponentially harder problem. Real roboticists should chime in...
- FloorEgg 1y agoAlso not a robotics guy, but that all sounds right to me... What I do have deep experience in is market abstractions and jobs to be done theory. There are so many ways to describe intent, and it's extremely hard to describe intent precisely. So in addition to all the dimensions you brought up that relate to physical space, there is also the hard problem of mapping user intent to action with minimal "error", especially since the errors can have big consequences in the physical world. In other words, the "intent space" also has many dimensions to it, far beyond what LLMs can currently handle. On one end of the spectrum of consequences is the robot loads my dishwasher such that there is too much overlap and a bunch of the dishes don't get cleaned (what I really want is for the dishes to be clean, not for the dishes to be in the dishwasher), and on the other end we get the robot that overpowers humanity and turns the universe into paperclips. So maybe we have to master LLMs and probably a whole other paradigm before robots can really be general purpose and useful.
- jandrewrogers 1y agoThis understates the complexity of the problem. I have built a career modeling/learning entity behavior in the physical world at scale. Language is almost a trivial case by comparison. Even the existence of most relationships in the physical world can only be inferred, never mind dimensionality. The correlations are often weak unless you are able to work with data sets that far exceed the entire corpus of all human text, and sometimes not even then. Language has relatively unambiguous structure that simply isn't the norm in real space-time data models. In some cases we can't unambiguously resolve causality and temporal ordering in the physical world. Human brains aren't fussed by this. There is a powerful litmus test for things "AI" can do. Theoretically, indexing and learning are equivalent problems. There are many practical data models for which no scalable indexing algorithm exists in literature. This has an almost perfect overlap with data models that current AI tech is demonstrably incapable of learning. A company with novel AI tech that can learn a hard data model can demonstrate a zero-knowledge proof of capability by qualitatively improving indexing performance of said data models at scale. Synthetic "world models" so thoroughly nerf the computer science problem that they won't translate to anything real.
- noduerme 1y agoBut we don't need to know all the things that could happen if M joints moved in every possible way at the same time. We operate within normal constraints. When you see someone trip on a sidewalk and recover before falling on their face, that's still a physical system taking signals and suggesting corrections that could be simulated in a relatively straightforward newtonian virtual reality, and trained a billion times on with however many virtual joints and actuators. In terms of "world building", it makes sense for the "world" to not be dreamed up by an AI, but to have hard deterministic limits to bump up against in training. I guess what I mean is that humans in the world constantly face a lot of conditions that can lead to undefined behavior as well, but 99% of the time not falling on your face is good enough to get you a job washing dishes.
- amelius 1y agoIn other words, self driving cars and robot vacuum cleaners cannot exist. Hmm.
- Earw0rm 1y agoAutonomous vehicles are an interesting subset. Even though the system rules and I/O are tightly constrained, they're still struggling to match human performance in an open-world scenario, after a gigantic R&D investment with a crystal clear path to return. Fifteen years ago I thought that'd be a robustly solved problem by now. It's getting there, but I think I'll still need to invest in driving lessons for my teenage kids. Which is pretty annoying, honestly: expensive, dangerous for a newly qualified driver, and a massive waste of time that could be used for better things. (OK, track days and mountain passes are fun. 99% of driving is just boring, unnecessary suckage). What's notable: AVs have vastly better sensors than humans, masses of compute, potentially 10X reaction speed. What they struggle with is nuance and complexity. Also, AVs don't have to solve the exact same problems as a human driver. For example, parking lots: they don't need to figure out echelon parking or multi-storey lots, they can drop their passengers and drive somewhere else further away to park.
- simne 1y agoAs I could see, classic methods (used in children teaching) could create at least magnitude more data than we have now, just paraphrasing text (classic NLP), but depends on language (I'll try explain). Text really have lot of degrees of freedom, but depends on language, and even more on type of alphabet - modern English with phonetic alphabet is worst choice, because it is simplest, nearly nobody use second-third hidden meaning (I hear about 2-3 to 5-6 meanings depending on source); hieroglyphic languages are much more information rich (10-22 meanings); and what is interest, phonetic languages in totalitarian countries (like Russian) are also much more rich (8-12 meanings), because they used to hide few meanings from government to avoid punishment. Language difference (more dimensions) could be explanation of current achievements of China, superior to Western, and it could also be hint, on how to boost Western achievements - I mean, use more scientists from Eastern Europe and give more attention to Eastern European languages. For 3D robots, I see only one way - computational simulated environment.
- criddell 1y ago> in practice we currently have exponentially less real-world data for an exponentially harder problem Is that where learning comes in? Any actual AGI machine will be able to learn. We should be able to buy a robot that comes ready to learn and we teach it all the things we want it to do. That might mean a lot of broken dishes at first, but it's about what you would expect if you were to ask a toddler to load your dishes into the dishwasher. My personal bar for when we reach actual AGI is when it can be put in a robot body that can navigate our world, understand spatial relationships, and can learn from ordinary people.
- breuleux 1y ago> So it makes me wonder, is embodiment (advanced robotics) 1000x harder than LLMs from an information processing perspective? Essentially, yes, but I would go further in saying that embodiment is harder than intelligence in and of itself. I would argue that intelligence is a very simple and primitive mechanism compared to the evolved animal body, and the effectiveness of our own intelligence is circumstantial. We manage to dominate the world mainly by using brute force to simplify our environment and then maintaining and building systems on top of that simplified environment. If we didn't have the proper tools to selectively ablate our environment's complexity, the combinatorial explosion of factors would be too much to model and our intelligence would be of limited usefulness. And that's what we see with LLMs: I think they model relatively faithfully what, say, separates humans from chimps, but it lacks the animal library of innate world understanding which is supposed to ground intellect and stop it from hallucinating nonsense. It's trained on human language, which is basically the shadows in Plato's cave. It's very good at tasks that operate in that shadow world, like writing emails, or programming, or writing trite stories, but most of our understanding of the world isn't encoded in language, except very very implicitly, which is not enough. What trips us up here is that we find language-related tasks difficult, but that's likely because the ability evolved recently, not because they are intrinsically difficult (likewise, we find mental arithmetic difficult, but it not intrinsically so). As it turns out, language is simple. Programming is simple. I expect that logic and reasoning are also simple. The evolved animal primitives that actually interface with the real world, on the other hand, appear to be much more complicated (but time will tell).
- programjames 1y agoIt took about the same amount of time to evolve human-level intelligence as human-level mobility. Pretty much no other animal walks on two legs...
- trescenzi 1y agoThis is interesting to think about. It’s basically just birds and primates. Birds have an ancient evolutionary tree as they are dinosaurs, which did actually walk on two legs. But the gap between dinos and primates walking on two feet, I think, is tens of millions of years. So yea pretty long time.
- ACCount37 1y agoThe big robot AI issue is: no data! There is a lot of high quality text from diverse domains, there's a lot of audio or images or videos around. The largest robotics datasets are absolutely pathetic in size compared to that. We didn't collect or stockpile the right data in advance. Embodiment may be hard by itself, but doing embodiment in this data-barren wasteland is living hell. So you throw everything but the kitchen sink at the problem. You pre-train on non-robotics data to squeeze transfer learning for all its worth, you run hard sims, a hundred flavors of data augmentation, you get hardware and set up actual warehouses with test benches where robots try their hand at specific tasks to collect more data. And all of that combined only gets you to "meh" real world performance - slow, flaky, fairly brittle, and on relatively narrow tasks. Often good enough for an impressive demo, but not good enough to replace human workers yet. There's a reason why a lot of those bleeding edge AI powered robots are designed for and ship with either teleoperation capabilities, or demonstration-replay capabilities. Companies that are doing this hope to start pushing units first, and then use human operators to start building up some of the "real world" datasets they need to actually train those robots to be more capable of autonomous operation. Having to deal with Capital H Hardware is the big non-AI issue. You can push ChatGPT to 100 million devices, as long as you have a product people want to use for the price of "free", and the GPUs to deal with inference demand. You can't materialize 100 million actual physical robot bodies out of nowhere for free, GPUs or no GPUs. Scaling up is hard and expensive.
- Hendrikto 1y ago> And all of that combined only gets you to "meh" real world performance - slow, flaky, fairly brittle, and on relatively narrow tasks. Often good enough for an impressive demo, but not good enough to replace human workers yet. Sounds like LLMs to me.
- ACCount37 1y agoIt's like GPT-3.5 - a proof-of-concept tech demo more than a product. I don't think further improvements are impossible, not at all. They're just hard to get at.
- dragonwriter 1y ago> 10+ years ago I expected we would get AI that would impact blue collar work long before AI that impacted white collar work. We did. Like, to the point that the AI that radically impacted blue collar work isn't even part of what is considered “AI” any more.
- mikeyouse 1y agoI think it's Benedict Evans who frequently posts about 'blue collar' AI work not looking like humanoid robots but instead Amazon fulfillment centers keeping track of millions of individual items or tomato picking robots with MV cameras only keeping the ripe ones as it picks at absurd rates. There are endless corners of the physical world right now where it's not worth automating a task if you need to assign an engineer and develop a software competency as a manufacturing or retail company, but would absolutely be worth it if you had a generalizable model that you could point-and-shoot at them.
- noduerme 1y agoOr a generalized model to develop them in a virtual sandbox before deploying them physically, which I think is more likely.
- don_esteban 1y agoI think the bottleneck for this is still the cost of the physical hw of the robot, and its maintenance. You need a fairly robust one that needs little maintenance, with a multitude of good sensors and precise actuators to be even remotely useful for sufficiently wide range of tasks (so that you have economy of scales). None of that comes cheap.
- foxglacier 1y agoRobots are only harder because they have expensive hardware. We already have robots that can load dishwashers and do other manual work but humans are cheaper so there isn't much of a market for them. The rising tide idea came from a 1997 paper by Moravec. Here's a nice graphic and subsequent history https://lifearchitect.ai/flood/ https://lifearchitect.ai/flood/ Interestingly, Moravec also stated: "When the highest peaks are covered, there will be machines than can interact as intelligently as any human on any subject. The presence of minds in machines will then become self−evident." We pretty much have those today so by 1997 standards, machines have minds, yet somehow we moved the goalposts and decided that doesn't count anymore. Even if LLMs end up being strictly more capable than every human on every subject, I'm sure we'll find some new excuse why they don't have minds or aren't really intelligent.

The presence of minds in machines will then become self−evident > We pretty much have those today so by 1997 standards, machines have minds, yet somehow we moved the goalposts and decided that doesn't count anymore What you describe as "moving the goalposts" could also just be explained as simply not meeting the standard of "as intelligently as any human on any subject". Even in the strongest possible example of LLM's strengths applying their encyclopedic knowledge and (more limited) ability to apply that knowledge for a given subject I don't think they meet that bar. Especially if we're comparing to a human over a time period greater than 30 minutes or so.
- chrchr 1y agoPart of the answer to this puzzle is that your dishwasher itself is a robot that washes dishes, and has had enormous impact on blue collar jobs since its invention and widespread deployment. There are tons of labor saving devices out there doing blue collar work that we don't think of as robots or as AI.
- zer00eyz 1y ago> 10+ years ago I expected we would get AI that would impact blue collar work long before AI that impacted white collar work. Not sure exactly where I got the impression, but I remember some "rising tide of AI" analogy and graphic that had artists and scientists positioned on the high ground. The moment you strip away the magical thinking, the humanization (bugs not hallucinations) what you realize is that this is just progress. Ford in the 1960's putting in the first robot arms vs auto manufacturing today. The phone: from switch board operators, to mechanical switching to digital to... (I think phone is in some odd hybrid era with text but only time will tell). Draftsmen in the 1970's all replaced by autocad by the 90's. GO further back to 1920, 30 percent of Americans were farmers, today thats less than 2. Humans, on very human scales are very good at finding all new ways of making ourselves "busy" and "productive".
- mbac32768 1y agoWe think this because ten years ago we were all having our minds blown by DeepMind's game playing achievements and videos of dancing robots and thought this meant blue collar work would be solved imminently. But most of these solutions were more crude than they let on, and you wouldn't really know unless you were working in AI already. Watch John Carmack's recent talk at Upper Bound if you want him to see him destroy like a trillion dollars worth of AI hype. https://m.youtube.com/watch?v=rQ-An5bhkrs&t=11303s&pp=2AGnWJACAQ%3D%3D https://m.youtube.com/watch?v=rQ-An5bhkrs&t=11303s&pp=2AGnWJ... Spoiler: we're nowhere close to AGI
- uncircle 1y agoThank you for this update. I vividly remember a few years ago the excitement of John Carmack announcing he was retreating into his cave to do some deep work on AGI, pushing the boundaries of the current AI research. I truly appreciate Carmack's intellectual honesty now at announcing "yeah, no, LLMs are not the way to go to recreate anything remotely close to human intelligence.". In fact, and I quote him, "we do not even have a line of sight to [the fundamentals of intelligence]." I'm honestly relieved that one of the brightest minds in computing, with all the resources and desire to create actual super-intelligences, has had to temper hard his expectations.
- hackinthebochs 1y agoI don't think that quote from Carmack represents some deeply considered conclusion. He started off his efforts with embodiment. He either never considered LLMs a path towards AGI, or thought he didn't personally have anything to contribute to LLMs (he talked about it early on in his journey but I don't remember the specifics). He didn't spend a year investigating LLMs and then decide that they weren't the path to AGI. The point is that he has no special insight regarding LLMs relationship to AGI and its misleading to imply that his current effort towards building AGI that eschew LLMs is an expert opinion.
- uncircle 1y agoYes, I meant to say that, for Carmack, no type of modern AI research has figured out the path to actual general intelligence. I just didn't want to use the meaningless "AI" buzzword, and these days all the focus and money is on large language models, especially when talking about the end goal of AGI.
- bflesch 1y agoThe problem is not the robot loading the diswasher, it is the dishwasher. The dishwasher (and general kitchen electronics) industry has not innovated in a long time. My prediction is a new player will come in who vertically integrates these currently disjoint industries and product. The tableware used should be compatible with the dishwasher, the packaging of my groceries should be compatible with the cooking system. Like a mini-factory. But current vendors have no financial incentive to do so, because if you take a step back the whole notion of putting one room of your apartment full with random electronics just to cook a meal once in a blue moon is deeply inefficient. End-to-end food automation is coming to the restaurant business, and I hope it pushes prices of meals so far down that having a dedicated room for a kitchen in the apartment is simply not worth it. That's the "utopia" version of things. In reality, we see prices for fast food (the most automated food business) going up while quality is going down. Does it make the established players more vulnerable to disruption? I think so.
- lambdaone 1y agoThis exists already in the form of "ready meals" a.k.a. TV dinners. Fast food shops are already substantially mechanised; huge effots have been made to robotize cooking, but people are still cheaper to hire. It's still nowhere near the quality of home-cooked food.
- bflesch 1y agoYes, there are a lot of garbage microwave food offerings, especially popular with the US population. As a European I'm talking about quality food made with an automated process and end-to-end automation, including ingredient procurement and cleanup. Not in competition with trash food but with proper food and local ingredients.
- criddell 1y ago> the whole notion of putting one room of your apartment full with random electronics just to cook a meal once in a blue moon is deeply inefficient You don't use your kitchen? After the rooms we sleep in, the kitchen is probably the most used space in my home. We are planning an upcoming renovation of our home and the kitchen is where we plan on spending the most money. > The tableware used should be compatible with the dishwasher Aside from non-dishwasher safe items, what tableware is incompatible with a dishwasher?
- api 1y agoEmbodiment is 1000x harder from a physical perspective. Look at how hard it is for us to make reliable laptop hinges or the articulated car door handle trend (started by Tesla) where they constantly break. These are simple mechanisms compared to any animal or human body. Our bodies last up to 80-100 years through not just constant regeneration but organic super-materials that rival anything synthetic in terms of durability within its spec range. Nature is full of this, like spider silk much stronger than steel or joints that can take repeated impacts for decades. This is what hundreds of millions to billions of years of evolution gets you. We can build robots this good but they are expensive, so expensive that just hiring someone to do it manually is cheaper. So the problem is that good quality robots are still much more expensive than human labor. The only areas where robots have replaced human labor is where the economics work, like huge volume manufacturing, or where humans can’t easily go or can’t perform. The latter includes tasks like lifting and moving things thousands of times larger than humans can or environments like high temperatures, deep space, the bottom of the ocean, radioactive environments, etc.
- petralithic 1y ago> 10+ years ago I expected we would get AI that would impact blue collar work long before AI that impacted white collar work. I'm not sure where people get this impression from, even back decades ago. Hardware is always harder than software. We had chess engines in the 20th century but a robotic hand that could move pieces? That was obviously not as easy because dealing with the physical world always has issues that dealing with the virtual doesn't.
