Robots are entering into a lot more areas of our lives than ever before and taking on different social roles. I love robots. I want to build robots. But I think we can't be naive about the possible harms and repercussions that we don't even expect. Because that will affect real people's lives. [MUSIC PLAYING] I think we have a very powerfully ambivalent relationship to robotics. And what I mean by that is, on the one hand we're drawn to them very strongly. They're very compelling and captivating as objects. But they also can be very scary in many cases. [GUNSHOTS] There's a host of concerns about robotic systems. Robots really represent the ability to have roaming, roving cameras that are capturing all kinds of information. All of the outdoor space, public space, places that were not observed, are going to be observed. And that data is all going to be captured and recorded. And we really don't have any kind of laws and regulations about how that can be utilized. The other thing that makes these very different is the fact that they move around. These are physically engaged with the world. And that means they can do a lot of harm in the physical world. And Amazon is talking about these quadrotors or octorotors that are going to be delivering packages to your front door. My first concern is, well, that's eight lawn mower blades coming down for a landing in front of your house, especially if it's carrying a box of books. Then you have a whole host of legal issues around who's responsible when these things do some harm. So there's the person who maybe owns the robot. There's the person who programs it or maybe tells it what to do. The idea of who really shares in these kinds of responsibilities becomes very critical, especially when we think about technological innovation. Because a company that manufactures a robot, if they hold all of the liability, then that's a really big impediment to them bringing to market these different technologies. But if we shift the law so that they don't have any liability or we greatly limit the kind of liability that they can have, we could wind up with a lot of really dangerous robots. So we really have to kind of find a balance between these. [MUSIC PLAYING] Asimov's three laws of robotics are pretty straightforward. A robot should obey a human being. A robot shouldn't do any harm. And a robot should then engage in effect self-preservation. But if you actually read Asimov's stories, in nearly every story, something goes awry largely because of these laws themselves. So what happens if two humans give orders to the robots and they're conflicting orders? What should the robot do then? He illustrated how just a simple rule-base morality does not work. [CRASHING NOISE] Robots are going to encounter some hair-raising scenarios. With self-driving cars on a narrow bridge and a school bus is headed toward it, what does it do Does it crash into the bus? Or does it drive off the bridge, taking you and the other passengers in the car to immediate death? In the ancient times, we used to believe that being moral was to transcend all your emotional responses and come up with the perfect analysis. But actually, an awful lot more comes into play, our ability to read the emotions of others, our consciousness, our understanding of habits and rituals and the meaning of different gestures. It's not clear that we know how to get that kind of understanding or appreciation into those systems. So will their analytical tools be satisfactory? They may win the game of Jeopardy. And the danger of that is that will make us liable to attribute levels or kinds of intelligence to them that they do not have and may lead to situations where we become increasingly reliant on them managing tools that they won't really know how to manage when that idiosyncratic and truly dangerous situation arises. I think the revolution in military robotics has been I think just the widespread adoption and use of the unmanned aerial systems by the US military. As these things make mistakes, we don't really know who's necessarily controlling them. If they've been programmed, again, who's responsible? So it becomes much more easy to distance yourself from the responsibility. And I think in the case of autonomous systems, it's a really big question. Because if these things accidentally kill people or commit something which, if it was done by a human, we would consider it a war crime, now it's being done by a machine, so is that just a technological error? Or is it a war crime? In legal terms, that's really about intention to commit a war crime. Otherwise, it's just sort of a mistake, which is very different than in product liability. So if you make a mistake with product liability, there's a lawsuit and the company still has to pay even though they didn't intend the harm. But in war, that's not the case. I think robots are not a threat in and of themselves. I think we have to worry about how they're used. And we have to design them and build them very responsibly. But I think we can't be naive about the possible harms and repercussions and the ways that they may be used that we don't approve of or the ways that we don't even expect, so relieving us of responsibility for our actions because we can point to the robot and say, well, it's not my responsibility. I think that's a kind of abdication of responsibility. It's a threat to who we are as humans and how we develop as a society. What interests me is how humans are starting to interact with robots that views robots not so much as objects but as lifelike things and the ethical questions that come along with that. Will you be my friend? Sure thing, Martin. Anthropomorphism is our tendency to project human-like qualities on animals or life-like qualities on objects. And the interesting thing about robots, particularly social robots, is that just the fact that we're having something moving around in our physical space that we can't quite anticipate lends itself to this projection. And we start to name these object or give them a gender or ascribe intent or states of mind to them. We'll even feel bad for them if they get stuck under the couch. And so we start to perceive these objects differently than we do other objects like toasters. This can get actually pretty extreme. So I did a workshop where my friend [INAUDIBLE] and I gave people little robotic dinosaurs and had them play with them. And then we asked them to torture and kill them. And they had a lot of trouble doing it. They basically refused to even hit the things. So anthropomorphism can go a long way in how we're willing to treat things. Even with the primitive social robots we have now, there are YouTube videos of robots being tortured or treated violently. And the comments underneath these videos are very polarized. And some people already get very upset by this type of behavior. We're not at this stage yet in robotic development that robots could actually experience something that's anywhere near to how we imagine our own pain experience. So the question is not do the robots actually feel it when you hurt them? The question is more, what do we feel when we hurt them? One could imagine especially a child who doesn't really understand the difference between a cat and a robotic object becoming either traumatized or desensitized to this type of behavior. If our research shows that violent behavior and hurting robots translates to treating other humans in a violent way or turning off parts of us that are empathetic, then yes, we probably should prevent people from hurting robots. If we put a red line in the sand right now, that doesn't mean that we will never see terminator-like creatures. But it means we're trying to design in the appropriate ethical considerations in today's systems. It's going to be more important what we project onto robots and how we interact with them and what roles they play in society. And that's going to drive what moral status we give them, essentially. And I think that's why it's important for us collectively to also think about who we are as humans and how we develop as a society. [MUSIC PLAYING]
