0:00:00.691,0:00:03.849 I write fiction sci-fi thrillers, 0:00:03.849,0:00:06.042 so if I say "killer robots," 0:00:06.042,0:00:08.403 you'd probably think something like this. 0:00:08.403,0:00:10.958 But I'm actually not here to talk about fiction. 0:00:10.958,0:00:13.906 I'm here to talk about very real killer robots, 0:00:13.906,0:00:17.028 autonomous combat drones. 0:00:17.028,0:00:20.655 Now, I'm not referring to Predator and Reaper drones, 0:00:20.655,0:00:23.915 which have a human making targeting decisions. 0:00:23.915,0:00:27.044 I'm talking about fully autonomous robotic weapons 0:00:27.044,0:00:29.698 that make lethal decisions about human beings 0:00:29.698,0:00:32.115 all on their own. 0:00:32.115,0:00:36.115 There's actually a technical term for this: lethal autonomy. 0:00:36.115,0:00:38.971 Now, lethally autonomous killer robots 0:00:38.971,0:00:42.040 would take many forms -- flying, driving, 0:00:42.040,0:00:44.786 or just lying in wait. 0:00:44.786,0:00:47.895 And actually, they're very quickly becoming a reality. 0:00:47.895,0:00:50.379 These are two automatic sniper stations 0:00:50.379,0:00:54.516 currently deployed in the DMZ between North and South Korea. 0:00:54.516,0:00:56.687 Both of these machines are capable of automatically 0:00:56.687,0:01:00.211 identifying a human target and firing on it, 0:01:00.211,0:01:04.535 the one on the left at a distance of over a kilometer. 0:01:04.535,0:01:08.124 Now, in both cases, there's still a human in the loop 0:01:08.124,0:01:10.496 to make that lethal firing decision, 0:01:10.496,0:01:15.909 but it's not a technological requirement. It's a choice. 0:01:15.909,0:01:19.002 And it's that choice that I want to focus on, 0:01:19.002,0:01:21.643 because as we migrate lethal decision-making 0:01:21.643,0:01:24.752 from humans to software, 0:01:24.752,0:01:28.228 we risk not only taking the humanity out of war, 0:01:28.228,0:01:31.754 but also changing our social landscape entirely, 0:01:31.754,0:01:33.978 far from the battlefield. 0:01:33.978,0:01:38.487 That's because the way humans resolve conflict 0:01:38.487,0:01:40.220 shapes our social landscape. 0:01:40.220,0:01:42.853 And this has always been the case, throughout history. 0:01:42.853,0:01:45.514 For example, these were state-of-the-art weapons systems 0:01:45.514,0:01:47.593 in 1400 A.D. 0:01:47.593,0:01:50.737 Now they were both very expensive to build and maintain, 0:01:50.737,0:01:53.977 but with these you could dominate the populace, 0:01:53.977,0:01:57.866 and the distribution of political power in feudal society reflected that. 0:01:57.866,0:02:00.553 Power was focused at the very top. 0:02:00.553,0:02:04.081 And what changed? Technological innovation. 0:02:04.081,0:02:05.952 Gunpowder, cannon. 0:02:05.952,0:02:09.769 And pretty soon, armor and castles were obsolete, 0:02:09.769,0:02:12.302 and it mattered less who you brought to the battlefield 0:02:12.302,0:02:16.081 versus how many people you brought to the battlefield. 0:02:16.081,0:02:19.719 And as armies grew in size, the nation-state arose 0:02:19.719,0:02:23.399 as a political and logistical requirement of defense. 0:02:23.399,0:02:25.775 And as leaders had to rely on more of their populace, 0:02:25.775,0:02:27.608 they began to share power. 0:02:27.608,0:02:30.207 Representative government began to form. 0:02:30.207,0:02:33.495 So again, the tools we use to resolve conflict 0:02:33.495,0:02:36.799 shape our social landscape. 0:02:36.799,0:02:40.863 Autonomous robotic weapons are such a tool, 0:02:40.863,0:02:46.031 except that, by requiring very few people to go to war, 0:02:46.031,0:02:50.871 they risk re-centralizing power into very few hands, 0:02:50.871,0:02:57.386 possibly reversing a five-century trend toward democracy. 0:02:57.386,0:02:59.143 Now, I think, knowing this, 0:02:59.143,0:03:03.495 we can take decisive steps to preserve our democratic institutions, 0:03:03.495,0:03:07.474 to do what humans do best, which is adapt. 0:03:07.474,0:03:09.479 But time is a factor. 0:03:09.479,0:03:12.330 Seventy nations are developing remotely-piloted 0:03:12.330,0:03:14.487 combat drones of their own, 0:03:14.487,0:03:17.080 and as you'll see, remotely-piloted combat drones 0:03:17.080,0:03:21.552 are the precursors to autonomous robotic weapons. 0:03:21.552,0:03:24.319 That's because once you've deployed remotely-piloted drones, 0:03:24.319,0:03:27.703 there are three powerful factors pushing decision-making 0:03:27.703,0:03:32.303 away from humans and on to the weapon platform itself. 0:03:32.303,0:03:37.562 The first of these is the deluge of video that drones produce. 0:03:37.562,0:03:41.415 For example, in 2004, the U.S. drone fleet produced 0:03:41.415,0:03:46.727 a grand total of 71 hours of video surveillance for analysis. 0:03:46.727,0:03:51.226 By 2011, this had gone up to 300,000 hours, 0:03:51.226,0:03:54.375 outstripping human ability to review it all, 0:03:54.375,0:03:58.039 but even that number is about to go up drastically. 0:03:58.039,0:04:00.614 The Pentagon's Gorgon Stare and Argus programs 0:04:00.614,0:04:03.778 will put up to 65 independently operated camera eyes 0:04:03.778,0:04:05.816 on each drone platform, 0:04:05.816,0:04:09.119 and this would vastly outstrip human ability to review it. 0:04:09.119,0:04:11.279 And that means visual intelligence software will need 0:04:11.279,0:04:15.327 to scan it for items of interest. 0:04:15.327,0:04:16.675 And that means very soon 0:04:16.675,0:04:19.422 drones will tell humans what to look at, 0:04:19.422,0:04:21.919 not the other way around. 0:04:21.919,0:04:24.392 But there's a second powerful incentive pushing 0:04:24.392,0:04:27.775 decision-making away from humans and onto machines, 0:04:27.775,0:04:30.647 and that's electromagnetic jamming, 0:04:30.647,0:04:32.883 severing the connection between the drone 0:04:32.883,0:04:35.697 and its operator. 0:04:35.697,0:04:38.315 Now we saw an example of this in 2011 0:04:38.315,0:04:41.271 when an American RQ-170 Sentinel drone 0:04:41.271,0:04:45.578 got a bit confused over Iran due to a GPS spoofing attack, 0:04:45.578,0:04:50.692 but any remotely-piloted drone is susceptible to this type of attack, 0:04:50.692,0:04:52.744 and that means drones 0:04:52.744,0:04:56.364 will have to shoulder more decision-making. 0:04:56.364,0:04:59.407 They'll know their mission objective, 0:04:59.407,0:05:04.252 and they'll react to new circumstances without human guidance. 0:05:04.252,0:05:06.833 They'll ignore external radio signals 0:05:06.833,0:05:09.163 and send very few of their own. 0:05:09.163,0:05:11.169 Which brings us to, really, the third 0:05:11.169,0:05:15.031 and most powerful incentive pushing decision-making 0:05:15.031,0:05:18.373 away from humans and onto weapons: 0:05:18.373,0:05:21.666 plausible deniability. 0:05:21.666,0:05:24.553 Now we live in a global economy. 0:05:24.553,0:05:28.887 High-tech manufacturing is occurring on most continents. 0:05:28.887,0:05:31.801 Cyber espionage is spiriting away advanced designs 0:05:31.801,0:05:33.687 to parts unknown, 0:05:33.687,0:05:35.701 and in that environment, it is very likely 0:05:35.701,0:05:40.435 that a successful drone design will be knocked off in contract factories, 0:05:40.435,0:05:42.605 proliferate in the gray market. 0:05:42.605,0:05:45.065 And in that situation, sifting through the wreckage 0:05:45.065,0:05:48.025 of a suicide drone attack, it will be very difficult to say 0:05:48.025,0:05:52.425 who sent that weapon. 0:05:52.425,0:05:55.225 This raises the very real possibility 0:05:55.225,0:05:58.160 of anonymous war. 0:05:58.160,0:06:00.774 This could tilt the geopolitical balance on its head, 0:06:00.774,0:06:04.265 make it very difficult for a nation to turn its firepower 0:06:04.265,0:06:07.113 against an attacker, and that could shift the balance 0:06:07.113,0:06:10.877 in the 21st century away from defense and toward offense. 0:06:10.877,0:06:14.001 It could make military action a viable option 0:06:14.001,0:06:16.289 not just for small nations, 0:06:16.289,0:06:18.834 but criminal organizations, private enterprise, 0:06:18.834,0:06:21.313 even powerful individuals. 0:06:21.313,0:06:24.641 It could create a landscape of rival warlords 0:06:24.641,0:06:28.321 undermining rule of law and civil society. 0:06:28.321,0:06:31.937 Now if responsibility and transparency 0:06:31.937,0:06:34.321 are two of the cornerstones of representative government, 0:06:34.321,0:06:38.641 autonomous robotic weapons could undermine both. 0:06:38.641,0:06:40.187 Now you might be thinking that 0:06:40.187,0:06:42.433 citizens of high-tech nations 0:06:42.433,0:06:45.136 would have the advantage in any robotic war, 0:06:45.136,0:06:48.769 that citizens of those nations would be less vulnerable, 0:06:48.769,0:06:53.057 particularly against developing nations. 0:06:53.057,0:06:56.581 But I think the truth is the exact opposite. 0:06:56.581,0:06:58.832 I think citizens of high-tech societies 0:06:58.832,0:07:02.561 are more vulnerable to robotic weapons, 0:07:02.561,0:07:07.026 and the reason can be summed up in one word: data. 0:07:07.026,0:07:10.507 Data powers high-tech societies. 0:07:10.507,0:07:13.697 Cell phone geolocation, telecom metadata, 0:07:13.697,0:07:17.169 social media, email, text, financial transaction data, 0:07:17.169,0:07:20.701 transportation data, it's a wealth of real-time data 0:07:20.701,0:07:24.074 on the movements and social interactions of people. 0:07:24.074,0:07:27.849 In short, we are more visible to machines 0:07:27.849,0:07:30.091 than any people in history, 0:07:30.091,0:07:35.707 and this perfectly suits the targeting needs of autonomous weapons. 0:07:35.707,0:07:37.445 What you're looking at here 0:07:37.445,0:07:40.691 is a link analysis map of a social group. 0:07:40.691,0:07:44.325 Lines indicate social connectedness between individuals. 0:07:44.325,0:07:47.205 And these types of maps can be automatically generated 0:07:47.205,0:07:51.920 based on the data trail modern people leave behind. 0:07:51.920,0:07:54.397 Now it's typically used to market goods and services 0:07:54.397,0:07:58.813 to targeted demographics, but it's a dual-use technology, 0:07:58.813,0:08:02.173 because targeting is used in another context. 0:08:02.173,0:08:04.733 Notice that certain individuals are highlighted. 0:08:04.733,0:08:08.013 These are the hubs of social networks. 0:08:08.013,0:08:11.603 These are organizers, opinion-makers, leaders, 0:08:11.603,0:08:14.285 and these people also can be automatically identified 0:08:14.285,0:08:16.667 from their communication patterns. 0:08:16.667,0:08:18.813 Now, if you're a marketer, you might then target them 0:08:18.813,0:08:21.356 with product samples, try to spread your brand 0:08:21.356,0:08:24.185 through their social group. 0:08:24.185,0:08:26.138 But if you're a repressive government 0:08:26.138,0:08:30.948 searching for political enemies, you might instead remove them, 0:08:30.948,0:08:33.708 eliminate them, disrupt their social group, 0:08:33.708,0:08:36.877 and those who remain behind lose social cohesion 0:08:36.877,0:08:39.498 and organization. 0:08:39.498,0:08:42.822 Now in a world of cheap, proliferating robotic weapons, 0:08:42.822,0:08:45.457 borders would offer very little protection 0:08:45.457,0:08:47.403 to critics of distant governments 0:08:47.403,0:08:51.049 or trans-national criminal organizations. 0:08:51.049,0:08:54.542 Popular movements agitating for change 0:08:54.542,0:08:58.151 could be detected early and their leaders eliminated 0:08:58.151,0:09:01.062 before their ideas achieve critical mass. 0:09:01.062,0:09:03.653 And ideas achieving critical mass 0:09:03.653,0:09:07.589 is what political activism in popular government is all about. 0:09:07.589,0:09:11.586 Anonymous lethal weapons could make lethal action 0:09:11.586,0:09:15.368 an easy choice for all sorts of competing interests. 0:09:15.368,0:09:19.102 And this would put a chill on free speech 0:09:19.102,0:09:24.410 and popular political action, the very heart of democracy. 0:09:24.410,0:09:27.324 And this is why we need an international treaty 0:09:27.324,0:09:30.864 on robotic weapons, and in particular a global ban 0:09:30.864,0:09:34.772 on the development and deployment of killer robots. 0:09:34.772,0:09:38.026 Now we already have international treaties 0:09:38.026,0:09:41.412 on nuclear and biological weapons, and, while imperfect, 0:09:41.412,0:09:43.700 these have largely worked. 0:09:43.700,0:09:47.468 But robotic weapons might be every bit as dangerous, 0:09:47.468,0:09:50.756 because they will almost certainly be used, 0:09:50.756,0:09:55.783 and they would also be corrosive to our democratic institutions. 0:09:55.783,0:09:59.251 Now in November 2012 the U.S. Department of Defense 0:09:59.251,0:10:01.709 issued a directive requiring 0:10:01.709,0:10:06.228 a human being be present in all lethal decisions. 0:10:06.228,0:10:11.004 This temporarily effectively banned autonomous weapons in the U.S. military, 0:10:11.004,0:10:14.757 but that directive needs to be made permanent. 0:10:14.757,0:10:19.133 And it could set the stage for global action. 0:10:19.133,0:10:22.978 Because we need an international legal framework 0:10:22.978,0:10:25.116 for robotic weapons. 0:10:25.116,0:10:28.044 And we need it now, before there's a devastating attack 0:10:28.044,0:10:31.196 or a terrorist incident that causes nations of the world 0:10:31.196,0:10:33.120 to rush to adopt these weapons 0:10:33.120,0:10:36.891 before thinking through the consequences. 0:10:36.891,0:10:39.872 Autonomous robotic weapons concentrate too much power 0:10:39.872,0:10:46.155 in too few hands, and they would imperil democracy itself. 0:10:46.155,0:10:48.841 Now, don't get me wrong, I think there are tons 0:10:48.841,0:10:51.459 of great uses for unarmed civilian drones: 0:10:51.459,0:10:55.398 environmental monitoring, search and rescue, logistics. 0:10:55.398,0:10:58.224 If we have an international treaty on robotic weapons, 0:10:58.224,0:11:01.811 how do we gain the benefits of autonomous drones 0:11:01.811,0:11:04.459 and vehicles while still protecting ourselves 0:11:04.459,0:11:08.439 against illegal robotic weapons? 0:11:08.439,0:11:13.180 I think the secret will be transparency. 0:11:13.180,0:11:16.193 No robot should have an expectation of privacy 0:11:16.193,0:11:19.644 in a public place. 0:11:19.644,0:11:24.692 (Applause) 0:11:24.692,0:11:26.737 Each robot and drone should have 0:11:26.737,0:11:29.620 a cryptographically signed I.D. burned in at the factory 0:11:29.620,0:11:32.543 that can be used to track its movement through public spaces. 0:11:32.543,0:11:35.924 We have license plates on cars, tail numbers on aircraft. 0:11:35.924,0:11:37.765 This is no different. 0:11:37.765,0:11:39.777 And every citizen should be able to download an app 0:11:39.777,0:11:42.902 that shows the population of drones and autonomous vehicles 0:11:42.902,0:11:45.331 moving through public spaces around them, 0:11:45.331,0:11:48.064 both right now and historically. 0:11:48.064,0:11:51.612 And civic leaders should deploy sensors and civic drones 0:11:51.612,0:11:53.956 to detect rogue drones, 0:11:53.956,0:11:57.132 and instead of sending killer drones of their own up to shoot them down, 0:11:57.132,0:12:00.124 they should notify humans to their presence. 0:12:00.124,0:12:02.730 And in certain very high-security areas, 0:12:02.730,0:12:04.639 perhaps civic drones would snare them 0:12:04.639,0:12:07.480 and drag them off to a bomb disposal facility. 0:12:07.480,0:12:10.507 But notice, this is more an immune system 0:12:10.507,0:12:11.828 than a weapons system. 0:12:11.828,0:12:14.420 It would allow us to avail ourselves of the use 0:12:14.420,0:12:16.452 of autonomous vehicles and drones 0:12:16.452,0:12:20.747 while still preserving our open, civil society. 0:12:20.747,0:12:23.746 We must ban the deployment and development 0:12:23.746,0:12:25.608 of killer robots. 0:12:25.608,0:12:30.458 Let's not succumb to the temptation to automate war. 0:12:30.458,0:12:33.176 Autocratic governments and criminal organizations 0:12:33.176,0:12:36.132 undoubtedly will, but let's not join them. 0:12:36.132,0:12:38.023 Autonomous robotic weapons 0:12:38.023,0:12:40.074 would concentrate too much power 0:12:40.074,0:12:42.556 in too few unseen hands, 0:12:42.556,0:12:45.811 and that would be corrosive to representative government. 0:12:45.811,0:12:48.772 Let's make sure, for democracies at least, 0:12:48.772,0:12:51.376 killer robots remain fiction. 0:12:51.376,0:12:52.486 Thank you. 0:12:52.486,0:12:57.051 (Applause) 0:12:57.051,0:13:01.667 Thank you. (Applause)
