Robotics The Military Technology

Weapons Systems That Kill According To Algorithms Are Coming. What To Do? 514

Lasrick writes "Mark Gubrud has another great piece exploring the slippery slope we seem to be traveling down when it comes to autonomous weapons systems: Quote: 'Autonomous weapons are robotic systems that, once activated, can select and engage targets without further intervention by a human operator. Advances in computer technology, artificial intelligence, and robotics may lead to a vast expansion in the development and use of such weapons in the near future. Public opinion runs strongly against killer robots. But many of the same claims that propelled the Cold War are being recycled to justify the pursuit of a nascent robotic arms race. Autonomous weapons could be militarily potent and therefore pose a great threat.'"

      That's pretty much it.

      These are only a problem if they are built and used.

      We cannot stop anyone from building them (in secret). But we can get updates added to the Geneva Conventions. And we can choose how we deal with anyone who uses these.

      Although at the moment it looks like we (USA! USA!) will be the ones using them. So contact your Congress Critters and make sure they know that you'll support them if they vote to ban our usage of these.

        I doubt that other major powers are ignoring such technology. I think other powers have a more closed procurement process and greater control over their design/development bureaus. We are less likely to hear about their designs until they are fielded or made available for export.

And corruptible humans will sell these things under the table to less than scrupulous individuals for protection/collections purposes. Tanks and missiles go missing from the military all the time.

        because all evidence shows that the weak point always lies with the soldier that has to pull the trigger and decide to kill a fellow human being.

        All evidence that I've seen shows that a large number - possibly even the majority - of soldiers have been brainwashed in to following orders unconditionally and will commit the most horrendous crimes against humanity when ordered to do so. And - even when not ordered - that same brainwashing includes training in not thinking of 'the enemy' as human, because that causes you to delay in the critical moment. So they dehumanise the enemy to the point that further atrocities can be committed even when not under orders to do so.

        Note that I don't blame the soldiers themselves in a lot of these situations - they are often good people who given time to think and reason it through would not behave that way, but their training has so messed with them that some actions they'll take don't reflect on the person they are.

        Also note that I did say "a large number of soldiers" and not all. There are plenty of cases you can find of soldiers going against orders they believe to be morally reprehensible, but the fact that OTHER soldiers then do it is a testament for the argument and not against it.

Once you have the sensors, pattern recognition, and mobility, there's no way to control all the possible applications.

        I think that there is a difference, though. It is one thing to create unrelated technology that when linked together is dangerous. It is another thing to just create technology that doesn't have an application outside of killing people. By your argument, every invention all they way back to using flint and tinder to create fire is nothing but a weapon, and why should we even have bothered?

        My prediction is that this technology will float about the edge of popular awareness, until an unbalanced individual sets up a KILLMAX(tm) brand 'smartgun perimeter defense turret' in an elementary school and murders a bunch of children and escapes because he didn't have to be on the scene. Then national outrage will lead to mass bans on such weapons.

        Should we be making such weapons? I don't know, I suppose that the argument can be made that they fill the same role as land mines, but have the upside that there is less problem with getting rid of them when the fighting stops. I find the glee we as a species have in building better was of killing each other to be really depressing on the whole.

    David's Sling, a novel by Marc Stiegler, is about the first "information age" weapons systems. These are autonomous robotic weapons that use algorithms to decide which targets to hit, and the algorithms are designed to take out enemy communications and decision-making. The weapons would try to identify important comm relays and take them out, and would analyze comm traffic to decide who is giving orders and take them out.

    The book was written before the fall of the Soviet Union, and the big finale of the book involves a massive Soviet invasion of Europe and the automated weapons save the day.

    Unlike some portrayals of technology, this book covers project planning, testing, and plausible software development. It contains tense scenes of QA testing, where the team makes sure their hardware designs are adequate and that their software mostly works. (They can remote-update the software but of course not the hardware.)

    Mostly they left the weapons autonomous, but there was a memorable scene where a robot was having trouble whether to kill someone, and the humans overrode the robot and had it leave the guy alone. (The guy was injured, and lying there but moving a little bit, and the robot was not sure whether the guy was already killed or should be killed again. Hmm, now that I think about it, this seems rather implausible, but it was a nifty scene in the book.)

    I can't remember the documentary; maybe Fog of War starring Satan's favorite child Robert McNamara. But, they figured out that in combat 25% of of soldiers weren't actually shooting at other people. They were intentionally shooting up in the air to avoid killing. So, part of the Army's training post WWII was to get soldiers to fire without thinking. The outcome was soldiers were more effective in battle. The consequence was soldiers weren't evaluating the act of taking lives until AFTER they'd done it which contributed to the increased mental issues Vietnam-era soldiers endure.

    • The 25% figure was proposed by S.L.A. Marshall in "Under Fire". He claimed it was from extensive interviews with US soldiers. That, at least, was a lie: he had no time to conduct all those interviews, no records have turned up, and no veterans remember such interviews. This doesn't mean the conclusion is wrong, but that the claimed support doesn't exist.

    Most of the comments on this article seem to be against this which is interesting, because every time an article about gun control gets posted, the highest rating comments are overwhelmingly from gun advocates, often with the argument that "guns don't kill people, people kill people". Whats the difference here? Surely robots don't kill people, people kill people?

      To kill someone with a knife, you have to stand very close to them and thrust the weapon into their body. To kill them with a gun, they have to be in line of sight and pull the trigger. To kill them with a drone, you need them on live camera and push a button. To kill them with an autonomous robot, you need to have a description of what they look like and what area they are located in and program that into the robot. Every step becomes more indirect, more emotionally detached.

      "Guns don't kill people" is just a slogan. A gun is a tool. For killing people. The real questions include "Do guns deter crime or make it more violent?" and "Does home gun ownership help prevent a government from turning on its own people?", but those have no simple answers, so they are not as useful in propaganda.

    Already exist. In our human behavior for one as part of instinct. As part of learned moral code. As part of operational orders such as rules of engagement. Simply codifying them and allowing a machine to do it isn't necessarily a bad thing. For one it takes away the negative mental effects it must have on human operators to have to make such life and death decisions.

    What we are really talking about is A) how well can it be coded, and B) avoiding potential mistakes, like "Kill all Humans!" or " All Humans must Die", or more serious making a distinction between soldier and non-combatant (assuming there is such a thing in the distant future).

    As war had taught us anything (and apparently it hasn't) Humans are perfectly capable of making mistakes and fucking that up all by themselves. Friendly fire happens all the time, and I can't give you a statistic, but it is a significant amount of issue and always has been. Civilian casualties particularly in urban centers has also been an issue since such things as urban centers have ever existed.

    At least if a machine is doing it, it will do it in a consistent, and discoverable way that is hopefully correctable, and not because some soldiers get mentally messed up by all the stress that putting people in those situations is bound to produce (or trying to desensitize them by making the enemy appear subhuman).

    Hopefully in the future all wars will be fought by autonomous robots, fighting other autonomous robots, who once they kill off all the opposing robot forces simply send a C3PO type representative to the defeated leadership to tell them they lost the war. I would imagine it would even make for pretty good TV (and betting opportunity: Go 23rd Fighting Heavy Mech Robot Battalion!).

I tell them to turn to the study of mathematics, for it is only there that they might escape the lusts of the flesh. -- Thomas Mann, "The Magic Mountain"
