    My biggest fear at the moment is robot armies and police forces.

    Case in point : we're all expecting China needs to invade Taiwan soon, or they will run out of soldiers because of the one child policies of the 70s/80s.

    Meanwhile, Ukraine is holding up against a "modern" army with quickly assembled drones.

    So it all seems a bit like "they'll never put tanks through the Ardennes", sort of ?

    Where and when will the first invasion of a country by a purely remote controlled, AI assisted army take place ?

    Will robot battalions embed civilians to act as human shields ? Will the AI learn to mistreat the locals to maintain fear, or will they see it as a needless distraction and rush to the center of powers ?

    If war is mostly played out from a disrance, will years of playing RTS give South Korea an edge ?

      > If war is mostly played out from a disrance

      I left a company because they pivoted to exactly this. There are so many companies in this space today, testing what they call "physical AI autonomy" today, and we have to recognize that this is our today.

      There are entire marketplace options for buying the pretrained, supported, private models, or the datasets if you have your own goals. If you're interested purely in ditzing around with GPS denied, or communications lost, you can do that today.

      I watched a demo video, in March where a company was sharing their remote instructed (note, not controlled) multiple format (spider, dog) robot swarm. The company claimed to be 35km away from where the drones dropped off the payloads, and the mission was engaged. Lightweight explosives were used to toss off a car.

      This is our present.

        It's going to happen and at some level I'd rather war casualties were measured in robots rather than people.

        My concern is the cottage industry of integrating guns with half baked AI at the lowest cost. And probably vibe coded too.

        The companies don't care - a sale is a sale. MoD maybe doesn't care - 90% accuracy and less human casualties on their own side are a win. Governments want to save money and by the time they find out the robots go rogue, it will be too late to do anything about it.

        • spwa4 2 hours ago ago

          The problem is always the same. It's not just MoD (is it MoW now?) that will have access to this.

          YoloV8 + optical flow works fine on an esp32. You want to give a drone rough coordinates for a refinery and hit something in it, like a storage tank? That'll work. This means, give it 5 years, relatively small groups will have access to it. This cannot be stopped.

          The only real answer is to work to have groups that you can trust to have access to this first.

      Not sure China actually needs to invade Taiwan - it just needs to be patient. cf Hong Kong.

      Totally agree with you about the dangers of autonomous killing machines - I think the two key problems here are.

      1. Reduces the political cost of going to war. Though as Iran has shown, there are other ways to exert political pressure even if the other military can hit you with almost impunity.

      2. This is really a follow on from the first - low cost ( in all meanings of the word ) weapons makes asymmetric warfare available to all - and this won't be limited to governments.

      On the positive side one of the potential outcomes of 2. is that countries and the world will need to operate on the principle of consent, as force will be nigh on impossible.

      Marching humanoid terminator robots will never be as cheap as a drone. Autonomous suicide drone swarms are what should terrify you.

      • fhub 4 hours ago ago

        Not marching, but Ukraine uses continuous track machine gun robots seemingly very effectively. They aren’t suicide ones.

        • rustyhancock an hour ago ago

          They are an interesting prospect but their use isn't quite as claimed.

          They are extremely vulnerable to the same drones humans are.

          It's more along the lines of this is a patch were not expecting active fighting this robot can act as a deterrent and surveillance.

          Cheaper and simpler than a loitering IRS drone. But more concentrated in domain.

          I believe for a while Samsung developed similar drones for the demilitarised zone in Korea. Those could be static as they were hard wired in.

      • imtringued 3 hours ago ago

        Most military grade drones cost $10k or more and they can only be used once.

        An optimized quadruped could probably be built for the same price and have an integrated 60mm mortar instead. The front legs act as the bipod and the rear legs would be designed to dig into the ground for stabilization. The only problem here is reloading the mortar, which could be done using a revolver style magazine. That's 5 shots per robot vs 1 per drone.

      • trhway 13 hours ago ago

        Autonomous suicide drone swarms are easily countered by autonomous interceptor swarms.

        >Marching humanoid terminator robots

        ground bots, not necessarily marching, do have their value. They can have bulletproof armor, while still be relatively lightweight and small and fast. They can easily carry even 20-25mm autocannon - very destructive weapon, sometimes can even succeed against a real tank.

        And imagine when a swarm of drones lifts a ground bot, brings and drops it right into the needed point and protects it from the enemy drones while the ground bot just destructs the things around. Synergy between different weapons system has always been the super-weapon.

        • DennisP 10 hours ago ago

          They can also sit in one spot guarding a position without using much battery. Ukraine recently took territory from Russian forces using ground bots, the first time it's been done without using soldiers on the ground. Now they're starting to scale the bots up to mass production.

          • trhway 9 hours ago ago

            the issue is remote control. Ground position means a lot of obstacles in addition to the widespread jamming. One can try to control the bot from the fiber-optic controlled drone hanging over, yet such complication has its own drawbacks. That means that ground bots are in real need of making them autonomous.

            • Gud 8 hours ago ago

              They don’t need to be remotely controlled anymore! Autonomous!

        Which of those is opening doors?

        • 4gotunameagain 6 hours ago ago

          Two drones. One to blast the door open, the next goes through.

          Still more cost effective than a humanoid robot, even in the presence of hundreds of doors.

          • fragmede 5 hours ago ago

            That breaks the building. If you want to destroy the whole thing, conventional weapons has that covered. Drones can't get through nets and doors. Though, have you considered packs of robot dogs with machine guns and one arm/hand? Cheaper than a fully bipedal humanoid robot.

              > have you considered packs of robot dogs with machine guns

              I don't have it to hand but already a few years ago a defense contractor had attached quite a heavy rifle on some sort of articulable mount to the top of something that looked exactly like Boston Dynamic's Spot. I'm not sure how much ammo it was capable of carrying or what it's range was but it's definitely a concerning development. I think I might become an enthusiastic custom anti-materiel rifle collector in the near future.

            • vasco 5 hours ago ago

              One thing exists and is known to work and be cheap. The other it's you musing about what will be possible. So they need to be judged differently. No land robot can move through a war environment in any effective way at the moment and also "open doors" etc. They are too slow. Not drones.

        If money or economics were relevant in these decisions, most wars would probably not play out in the first place. Tesla probably wouldn't be worth 1.2T. And we certainly wouldn't see AI buildouts happening at their current rates.

        Economics and costs only matter for normal humans, small countries, and efforts that might actually help humanity. They're not seemingly considerations in nefarious applications.

        • DennisP 10 hours ago ago

          It matters quite a bit. If your drone costs $1000, you can build a thousand times more of them than if a drone costs $1M. As the saying goes, quantity has a quality all its own.

          This is a lesson the US has yet to learn, and its military drones are really expensive. Ukraine learned it by necessity, and now it's building millions of drones annually.

            On the other hand, if Musk really flips his lid, he's one OTA away from a network of ground-delivered lithium bombs. The fear of humanoid bots is their banality: if a government or private company has a reason to build them, then the world is full of hardware with terrifying capability and questionable security.

            Not really. They’re fought over fear of the future, desire for control and power over other people. “It’s us or them” captures one of the core calculi of war. It’s not rational, it’s just an expression of evolutionary imperatives.

      Silly Devil's Advocate argument:

      What if there are no human soldiers or fighters at all? No-one needs to die in a war again, but wars are won by the side with the stronger tech.

      What are the possible outcomes of this? Technologically superior countries start a race to acquire more territory, so large blocks expand and absorb other countries? More wars? Fewer wars? More suffering? Less suffering?

      Disclaimer: I'm not imagining this is really possible. As long as some humans from group A don't want to be under the rule of group B, humans will resist and fight. But it is just a thought experiement.

        The births of 2025 will be the warriors of 2050. By then, a bunch of those will be needed to, you know, run things around the country. It's clear that China is going to use tech (as in, artificial wombs, neural implants for optimized beaurocracy, and plenty of robots.)

        My big question is:

        - will they keep the human bodies warm to care for the elderly, and send robots to war ?

        - will they keep the robots to take care of the elderly, and send the young's to war ?

        - will they dispose f the elderly to keep their edge ?

        - will they play long and wait things out ?

      Not sure if this is serious, but RTS skills are different from real-world battlefield skills. Macro is completely different, and while micro skills might be slightly transferrable, computers are so much better that no human will ever be microing real units on a real battlefield.

    • dyauspitr 8 hours ago ago

      We are less than 5 years from robot armies. I mean if you put a person behind a Unitree robot, we have robot armies now. Those things run pretty fast and are quite good at obstacle clearance. They also cost $20,000 per unit which is throwaway money by any metric. Full autonomy is real close though.

    • theshrike79 5 hours ago ago

      Remote controlled autonomous robots/drones can also be used for, say, elder care.

      A nurse can log in to a HelperBot remotely, check up on the client, tidy up the house and maybe even give medication. Instead of having to drive around between clients, losing maybe hours a day just on transit, one person can manage more people per day.

      ...but the same system can be modified for KillerBot easily like we know from EVERY SCI-FI BOOK EVER.

Because "fear gives men wings".

    A year ago this [0] table tennis robot backed by Google DeepMind was discussed on HN.

    It plays much worse and the HN discussion is anchored around whether it's OK to call it "human-level" or if the authors should have clarified that they meant a human who doesn't actually play table tennis. But it was accepted as being SOTA at that time.

    What happened since then? This looks like the kind of level of advance we see in, say, coding AIs, but I thought physical robotics was advancing much more slowly.

    A partial answer is that the new robot cheats in ways that DeepMind didn't seem to. It has high speed cameras all over the room and can detect spin by observing the logo on the ball. But I'm not sure this explains such a big advance.

      • neosat 13 hours ago ago

        As a player myself, and having seen much higher level player than me, reading the spin from the ball rotation (and in fact trajectory) of the ball is a common (if advanced) skill. Sometimes the movement of the bat can be deceptive (since with the same movement, where it contact on the bat, the finger pressure can affect the spin).

        For example, backspin/underspin balls will move slower after the first bounce and feel 'damper' while topspin will jump. So it's def. possible (and in fact reliable) to read the spin from the spin and trajectory of the ball.

        • QuantumGood 13 hours ago ago

          Visually reading spin is unreliable at all levels; the ITTF passed the two-color rubber rule requiring one black and one red side to neutralize players taking advantage of their opponents being unable to read the spin from watching the ball rotation via twiddling rackets with the same color rubber on both sides, but different characteristics.

              Ping pong paddles have two sides, with different characteristics for each side. Now the two sides have to have different colors so your opponent can see what you are hitting it with, where before you could use the same color on both sides and your opponent wouldn't be able to tell how the ball would react

    I'm very surprised to see the rapid advancement in robotics these days. After all the fancy demos of Boston Dynamics and others from 10 years ago, and no real advancement beyond them, we kinda learned to treat robotics as "fancy toys".

    Now, this feels to me very much like a Deep Blue moment in chess, when to everyone's surprise it won over Garry Kasparov 3.5 to 2.5. 20 years in, and no one even considers competing with chess engines.

    This Ace robot won over table tennis professionals in 3 matches and lost in 2. Even the score is similar. I wonder what it'll all look like in 20 years from now.

  • halfnhalf 15 hours ago ago

    Don't table tennis players learn to predict how the ball will act based on their opponents movements? Seems like if they aren't able to do that with a robot opponent (who doesn't look or behave like a human) then they wouldn't be able to play at their best.

    • ACCount37 15 hours ago ago

      I do expect this to have a "novelty edge" over human opponents - which can be closed with practice, on the human end.

      And, like many AIs, it can have "jagged capability" gaps, with inhuman failure modes living in them - which humans can learn to exploit, but the robot wouldn't adapt to their exploitation because it doesn't learn continuously. Happened with various types of ML AIs designed to fight humans.

      • Ferret7446 13 hours ago ago

        Only if you assume the AI can't improve. Otherwise, AI has a fundamental edge over humans in that they don't get old and die, and can be copied perfectly without an expensive retraining period

        • ACCount37 7 hours ago ago

          Oh, they can. They just need a human touch to actually improve.

          For now. It's a work in progress.

      • zingar 14 hours ago ago

        Chess players learned to exploit chess computers’ weaknesses in the beginning too, but they can’t any longer. This version of the robot might not learn continuously, but the next will be better.

        • cool_dude85 11 hours ago ago

          I believe there are still some echoes of the concept. Even top engines will play certain grandmaster draw lines unless told more or less explicitly not to. So if you were playing a match against Stockfish you'd want to play the Berlin draw as White every time, for example.

    • dethos 4 hours ago ago

      Exactly. There are cues that an opponent provides when approaching a ball that help the player prepare for and limit the range of possible responses (this happens with most racket games). With these robots, the players only find out after the ball is already coming in their direction.

      I wonder how much practice these players had against the machine in the weeks leading up to the actual game. That would be significant to ensure they are playing at their pro level.

    • LeCompteSftware 13 hours ago ago

      Yes, you're dead on:

        Rui Takenaka, an elite-level player who has won and lost matches against Ace, said in comments provided by Sony AI: "When it came to my serve, if I used a serve with complex spin, Ace also returned the ball with complex spin, which made it difficult for me. But when I used a simple serve - what we call a knuckle serve - Ace returned a simpler ball. That made it easier for me to attack on the third shot, and I think that was the key reason why I was able to win."
      
      It seems like the human players might be playing in a way that tacitly overestimates their AI opponents' intelligence and underestimates their skill. AFAIK the SOTA Go AIs are still vulnerable to certain very stupid adversarial strategies that wouldn't fool an amateur (albeit they're not something you'd come up with in normal play, more like a weird cheat code). I wonder if this could get ironed out with a bit more training against humans vs. simulation.
    • hermitcrab 15 hours ago ago

      You can predict the movement of the ball (speed, direction, spin) based on the movement of the bat relative to the ball. What the rest of the player's body is doing is irrelevant to predicting what the ball will do - but relevant to predicting where they will be when you make the return shot.

      • dethos 4 hours ago ago

        The movement of the "bat" is tied to the physical limitations of the arm and the positioning of the body. Something that can't be deduced or even perceived clearly from the movements of this robot.

        As I mentioned in a previous comment, it would be important to know how many weeks of preparation and training against this sort of robot the player had before the match.

  • nilslindemann 4 hours ago ago

    I find Sony's work valuable. In my opinion, the primary purpose of AI is still, first and foremost, to relieve us of the physical labor we don't want to do. The next step to be taken is to create a universal basic income. Evolution will then unfold, as creative people will be able to dedicate their whole life undisturbed to the problems they deem important.

    Here a video where one can actually see the robot in action:

    I'm not that excited about 'x beats human at y' anymore. I am more interested in 'x beats human at made up on the spot tasks p d and q'. That is starting to happen more generically and is a bigger sign of emerging capability. We can always create something confined that will beat humans, it isn't until recently that we are starting to be able to generally beat humans at tasks.

      Even club level players have access to tennis table 'robots'. They fire the ball at you and collect the return in a net. You can set the speed, position and spin. They are very basic compared to this robot, but useful for training.

  • allthetime 14 hours ago ago

    Much like the robots beating half marathon records in China recently… who cares? Cake making robots can make cakes way faster than human bakers. Cars and motorcycles go faster than bicyclists. It is a boring given that purpose made machines perform the tasks they are built to perform better than humans.

      It's an amazing feat of engineering because it requires constant micro-adjustments, something that robots couldn't do a few years ago.

        Yeah, thinking through it a bit further, the real story here, aside from the mechanical engineering, is the application of AI/machine learning/computer vision processing. The advancements that have made it possible to reason about, simulate, and react to the complexities of a spinning ball in a fraction of a second are pretty cool. My gripe is mostly that this article isn't focusing on and detailing this.

I'd be particularly interested in gladiatorial competitions since on top of super human athleticism blood sports have otherwise fallen out of favor due to the human cost.

    While the engineering behind this achievement is really impressive, it doesn't feel that important in the grand scheme of things.

    • jillesvangurp 10 hours ago ago

      The significance of ping pong is not beating humans but that it is a sport that depends on high precision, fast movement, and rapid responses. The aim of the game is to out maneuver the opponent and corner them such that they can't respond and adapt quickly enough. A robot beating a human means that it does this better, faster, and more precise. A few days ago, a bi pedal robot ran a a half marathon about eight or nine minutes faster than the fastest human can.

      These are not the clumsy robots of a few years ago that could only do simple, pre-programmed tasks and had to work in fenced off areas because they had no awareness of anything around them (including fragile people) but self stabilizing, inhumanly fast running robots that can operate in any kind of environment and adapt to a wide variety of tasks. And then complete those tasks at very high precision and speed.

      • vultour 27 minutes ago ago

        I'm sorry but none of this sounds in any way exciting or like a breakthrough. There are ASML machines that hit microscopic tin particles with a laser 50,000 times per second, but it's somehow an achievement we've managed to create a ping pong paddle that's fast enough to hit a ball? Precision robotics have been used in manufacturing for decades.

    • _carbyau_ 9 hours ago ago

      And humans have mastered radio waves for communication, washing machines for washing clothes, dishwashers for dishes etc etc.

      However, the point here is not that it makes a sport redundant, but that a type of observation, calculation, and movement has been achieved.

      I for one hope to see this tech in action from the customer side of a teppanyaki restaurant. It won't replace the humour of a good human teppanyaki chef but maybe I'll be able to afford it....
