1 00:00:03,800 --> 00:00:06,680 Speaker 1: Welcome to Stuff to Blow your Mind from how Stuff 2 00:00:06,680 --> 00:00:14,000 Speaker 1: Works dot com. Hey, welcome to Stuff to Blow your Mind. 3 00:00:14,040 --> 00:00:17,239 Speaker 1: My name is Robert Lamb and I'm Julie Douglas. And 4 00:00:17,920 --> 00:00:22,480 Speaker 1: as of this recording, the robots singularity has probably not occurred. 5 00:00:23,239 --> 00:00:25,040 Speaker 1: Mm hmmm as far as we know. As far as 6 00:00:25,079 --> 00:00:28,080 Speaker 1: we know, but we're not really sure how to define that, right, right, 7 00:00:28,200 --> 00:00:30,400 Speaker 1: It's kind of an evasive term. I mean, roughly, we're 8 00:00:30,400 --> 00:00:36,400 Speaker 1: talking about computers robots reaching the level where they not 9 00:00:36,560 --> 00:00:41,640 Speaker 1: only um um meet us on the same mental plane, 10 00:00:41,640 --> 00:00:43,959 Speaker 1: but they exceed us and they become greater than us, 11 00:00:44,000 --> 00:00:49,040 Speaker 1: and they and then in various scenarios could conceivably play out, 12 00:00:49,640 --> 00:00:51,640 Speaker 1: people really like to have fun with fun with the 13 00:00:52,040 --> 00:00:55,240 Speaker 1: darker images, they just leave us in the dust, like literally, yeah, 14 00:00:55,320 --> 00:00:57,240 Speaker 1: like they just they take over the world, or they 15 00:00:57,280 --> 00:01:00,800 Speaker 1: just decided to destroy all humans, or or our lives 16 00:01:00,840 --> 00:01:07,039 Speaker 1: become so robotic and so enhanced by robotics that that 17 00:01:07,120 --> 00:01:09,040 Speaker 1: the the human part of our life becomes kind of 18 00:01:09,080 --> 00:01:11,200 Speaker 1: a kind of a core to it. You know, it's 19 00:01:11,240 --> 00:01:14,160 Speaker 1: just but not a necessity of it. Well, I think 20 00:01:14,200 --> 00:01:18,119 Speaker 1: I love talking about the singularity because it does um, 21 00:01:18,160 --> 00:01:21,360 Speaker 1: it brings up so many different points of view, and 22 00:01:21,640 --> 00:01:23,600 Speaker 1: you and I have talked about it plenty and always 23 00:01:23,640 --> 00:01:28,120 Speaker 1: feel like you have like this very um positive outlook 24 00:01:28,520 --> 00:01:31,800 Speaker 1: on the Singularity, whereas sometimes I get paranoid and I think, 25 00:01:31,840 --> 00:01:35,640 Speaker 1: oh no, to be taken over says when you don't 26 00:01:35,640 --> 00:01:37,600 Speaker 1: even come into work and we have to call and 27 00:01:37,640 --> 00:01:40,160 Speaker 1: se who we are because it's the Singularity and anxiety 28 00:01:40,240 --> 00:01:42,720 Speaker 1: is getting taking over. Yes, those are the days when 29 00:01:42,720 --> 00:01:46,360 Speaker 1: I've locked myself in my bunker. Yeah. Whereas I tend 30 00:01:46,360 --> 00:01:47,840 Speaker 1: to look at it like, you know, if the if 31 00:01:47,880 --> 00:01:51,440 Speaker 1: the coffee machines become as smart as humans, then we're 32 00:01:51,480 --> 00:01:54,600 Speaker 1: just gonna have a really great coffee. I mean, that's sea. 33 00:01:54,800 --> 00:01:57,160 Speaker 1: I love that that that's the sort of positive pluck 34 00:01:57,240 --> 00:02:00,800 Speaker 1: that I'm talking about here. Um, But in that context, 35 00:02:00,840 --> 00:02:03,600 Speaker 1: you know, it does it seems Michael, Okay, this is 36 00:02:03,640 --> 00:02:05,400 Speaker 1: something that could be far away, or it could be 37 00:02:05,400 --> 00:02:09,200 Speaker 1: something that's really near. We don't know, but robots are 38 00:02:09,200 --> 00:02:13,239 Speaker 1: having a fundamental impact on our lives in myriad ways, right. Yeah. 39 00:02:13,280 --> 00:02:17,280 Speaker 1: I remember I was looking into some information about recruiting 40 00:02:17,360 --> 00:02:20,720 Speaker 1: into computing programs and they pointed out that there's virtually 41 00:02:20,760 --> 00:02:25,320 Speaker 1: no field of study anymore that does not contain programming 42 00:02:25,480 --> 00:02:28,480 Speaker 1: and uh and computerization, and it's going to get to 43 00:02:28,480 --> 00:02:30,919 Speaker 1: where there's going to be no part of of our 44 00:02:30,960 --> 00:02:33,640 Speaker 1: society that isn't touched by robotics in some way, shape 45 00:02:33,680 --> 00:02:36,600 Speaker 1: or form robotics or you know, or or really high 46 00:02:36,720 --> 00:02:40,440 Speaker 1: end programming or us even being touched by robots, right, 47 00:02:40,480 --> 00:02:43,520 Speaker 1: I mean we've talked about Roxy the sex Spot literally 48 00:02:43,520 --> 00:02:45,720 Speaker 1: touched by it. Well, I don't know if the robots 49 00:02:45,760 --> 00:02:49,080 Speaker 1: doing in this situation, the robots is being touched, I think, Oh, 50 00:02:49,120 --> 00:02:51,119 Speaker 1: but they are, I'm sure are very soon there will 51 00:02:51,160 --> 00:02:53,880 Speaker 1: be touching. Yeah, but it's very hard to argue this 52 00:02:53,919 --> 00:02:59,639 Speaker 1: consensual that's true unless it's programmed. I supposed Yeah, that's 53 00:02:59,639 --> 00:03:03,200 Speaker 1: a whole party. Um, And we will get to that definitely. 54 00:03:03,440 --> 00:03:06,680 Speaker 1: But again, thinking about robots and how they're being used 55 00:03:06,720 --> 00:03:10,760 Speaker 1: in day to day life, we actually turn to Dr 56 00:03:10,919 --> 00:03:13,640 Speaker 1: Ronald Arkin. He's the Regent's Professor in the School of 57 00:03:13,680 --> 00:03:16,560 Speaker 1: Interactive Computing and is the director of the Mobile Robot 58 00:03:16,680 --> 00:03:20,800 Speaker 1: Laboratory at the Georgia Institute Technology. Yeah, it's not a 59 00:03:20,800 --> 00:03:23,280 Speaker 1: mobile lab though. It doesn't you know, it's not like 60 00:03:23,600 --> 00:03:25,400 Speaker 1: it doesn't break away from the rest of the building 61 00:03:25,480 --> 00:03:30,960 Speaker 1: or anything. And uh, galvanting around Atlanta. No, No, but 62 00:03:31,240 --> 00:03:36,119 Speaker 1: he and his team, along with research engineer Alan Wagner, 63 00:03:36,400 --> 00:03:38,400 Speaker 1: they've blazed the way when it comes to robotics and 64 00:03:38,440 --> 00:03:44,000 Speaker 1: in particular thinking about robotic ethics, and they have created 65 00:03:44,040 --> 00:03:48,200 Speaker 1: a robot or robots that can deceive. Yeah, And it 66 00:03:48,200 --> 00:03:52,400 Speaker 1: all boils down to an algorithm, or more specifically a 67 00:03:52,440 --> 00:03:57,400 Speaker 1: cognitive deception modeling algorithm or or a series of algorithms, 68 00:03:57,720 --> 00:04:01,760 Speaker 1: and it involves not not only only giving the robot 69 00:04:02,120 --> 00:04:06,640 Speaker 1: the capacity to fool another robot or a human, but 70 00:04:06,720 --> 00:04:10,600 Speaker 1: giving it the ability to decide when to fool another human. 71 00:04:10,960 --> 00:04:13,240 Speaker 1: Because that's the important thing. We all have the ability 72 00:04:13,280 --> 00:04:15,200 Speaker 1: as humans. We all have the ability to see the 73 00:04:15,240 --> 00:04:18,880 Speaker 1: ability to lie. And one of the the the the 74 00:04:18,960 --> 00:04:21,240 Speaker 1: core things we have to decide in life is when 75 00:04:21,279 --> 00:04:23,560 Speaker 1: to tell the truth and when to lie. And if 76 00:04:23,600 --> 00:04:26,279 Speaker 1: it's if you're out of balance on that, life can 77 00:04:26,320 --> 00:04:28,080 Speaker 1: get pretty messy and nobody will want to hang out 78 00:04:28,120 --> 00:04:31,799 Speaker 1: with you either because you've never um, you never code 79 00:04:31,839 --> 00:04:35,560 Speaker 1: anything um for consumption, you never you know, dish out 80 00:04:35,560 --> 00:04:37,880 Speaker 1: a white liar two, or you just lie all the 81 00:04:37,920 --> 00:04:40,880 Speaker 1: time and are kind of a jerk. Yeah. Yeah, So 82 00:04:41,000 --> 00:04:43,479 Speaker 1: I mean we wouldn't want to create jerk robots. But 83 00:04:43,560 --> 00:04:45,760 Speaker 1: the problem is that that robots in their simple form 84 00:04:45,760 --> 00:04:49,119 Speaker 1: are they're they're robotic, they're they're they're they're not gonna 85 00:04:49,320 --> 00:04:52,080 Speaker 1: they're not gonna code anything um to make it go 86 00:04:52,120 --> 00:04:54,719 Speaker 1: down easier. Yeah. Yeah, So it is really interesting, like 87 00:04:54,760 --> 00:04:56,680 Speaker 1: how do you how do you do this? How do 88 00:04:56,720 --> 00:04:59,720 Speaker 1: you what? What is deception? Anyway, even when when you're 89 00:04:59,760 --> 00:05:02,520 Speaker 1: talking about a robot And so we actually talked to 90 00:05:03,279 --> 00:05:06,120 Speaker 1: Dr Arkin about this, and this is what he had 91 00:05:06,160 --> 00:05:10,160 Speaker 1: to say about deception and what it is defined as 92 00:05:10,200 --> 00:05:13,080 Speaker 1: in robotics. It's actually a definition that we borrowed from 93 00:05:13,080 --> 00:05:16,719 Speaker 1: cognitive science, which is a false communication that tends to 94 00:05:16,760 --> 00:05:21,200 Speaker 1: benefit the communicator. So the important thing is that you 95 00:05:21,240 --> 00:05:26,080 Speaker 1: will benefit by saying something that is untrue. Now in 96 00:05:26,120 --> 00:05:28,520 Speaker 1: the process has often been referred to as lying robots 97 00:05:28,520 --> 00:05:31,960 Speaker 1: and the like as well too. It's a false communication. 98 00:05:32,120 --> 00:05:34,400 Speaker 1: Is lying leaving a trail on the ground. I don't know, 99 00:05:34,520 --> 00:05:37,680 Speaker 1: that's a verbal act. I could argue this is more 100 00:05:37,680 --> 00:05:41,839 Speaker 1: expansive than simply lying. In this case, it's basically trying 101 00:05:41,880 --> 00:05:44,760 Speaker 1: to create a deception to make someone believe something that 102 00:05:44,920 --> 00:05:49,840 Speaker 1: isn't true and act in a way. The work that 103 00:05:49,920 --> 00:05:53,919 Speaker 1: we looked at in the military. For the military was 104 00:05:53,960 --> 00:05:57,039 Speaker 1: more a fundamental question of what deception is and how 105 00:05:57,040 --> 00:06:01,760 Speaker 1: it could be employed. So it's not soly writing up 106 00:06:01,800 --> 00:06:04,719 Speaker 1: look up tables and saying these are the sets of actions, 107 00:06:05,040 --> 00:06:07,080 Speaker 1: as I think I mentioned. If I didn't, there's an 108 00:06:07,160 --> 00:06:09,960 Speaker 1: entire field manual for the U. S. Army on deception 109 00:06:10,279 --> 00:06:14,640 Speaker 1: deceptive techniques, because it's important, it's crucially important in an 110 00:06:14,640 --> 00:06:19,240 Speaker 1: appropriate way to conduct warfare. Uh. But this isn't just 111 00:06:19,440 --> 00:06:22,000 Speaker 1: saying do this in this set of circumstances, do this 112 00:06:22,040 --> 00:06:24,479 Speaker 1: in this set of circumstances. This is I have to 113 00:06:24,600 --> 00:06:28,479 Speaker 1: understand you. I have speaking as a Roman. I have 114 00:06:28,560 --> 00:06:32,279 Speaker 1: to understand you and learn what your potential outcomes are. 115 00:06:32,480 --> 00:06:34,680 Speaker 1: And one of the other interesting factors in that paper, 116 00:06:34,680 --> 00:06:36,600 Speaker 1: which I was about to mention as well too, is 117 00:06:36,680 --> 00:06:39,960 Speaker 1: that it was observed, at least in this narrow case 118 00:06:40,160 --> 00:06:43,680 Speaker 1: that we studied, the more sensors that you have, the 119 00:06:43,760 --> 00:06:47,520 Speaker 1: more the easier it is to deceive you, which it 120 00:06:47,680 --> 00:06:50,800 Speaker 1: was not intuitively obvious. You think, gosh, you know, if 121 00:06:50,880 --> 00:06:53,560 Speaker 1: I have more ways to understand what's around me, I 122 00:06:53,680 --> 00:06:58,279 Speaker 1: would be more likely to get the right action. But 123 00:06:58,360 --> 00:07:02,440 Speaker 1: deception works in this particular, it appears due to the 124 00:07:02,480 --> 00:07:07,680 Speaker 1: fact that we can exploit multiple channels of information. You know, um, 125 00:07:07,720 --> 00:07:11,480 Speaker 1: hearing that, I can't help but be reminded of Isaac Asimov. 126 00:07:12,320 --> 00:07:14,800 Speaker 1: He of course had the classic book I Robot, which 127 00:07:14,880 --> 00:07:17,920 Speaker 1: is a series of short stories about about robots, and 128 00:07:17,920 --> 00:07:20,760 Speaker 1: they're very they're very analytical. They're all about, you know, 129 00:07:20,840 --> 00:07:23,640 Speaker 1: robots of being the three rules of robotics, and humans 130 00:07:23,680 --> 00:07:26,760 Speaker 1: trying to figure out how the robots are are are behaving. 131 00:07:27,000 --> 00:07:29,640 Speaker 1: And there's a story in there called Little Lost Robot. 132 00:07:29,720 --> 00:07:32,200 Speaker 1: And and in this a researcher loses his temper and 133 00:07:32,280 --> 00:07:35,680 Speaker 1: swears that a particular robot and tells it to get lost, 134 00:07:36,040 --> 00:07:40,360 Speaker 1: and it does so, and then the chief robo psychologist, Dr. 135 00:07:40,440 --> 00:07:43,600 Speaker 1: Susan Calvin comes in to find it. Um, So it 136 00:07:43,640 --> 00:07:46,400 Speaker 1: couldn't help it be reminded of that. It's a fairly 137 00:07:46,440 --> 00:07:50,280 Speaker 1: lighthearted tale. Yeah. Actually, that's that's interesting because just in 138 00:07:50,280 --> 00:07:55,040 Speaker 1: in the context of the experiment that Arkin and Wagner did, 139 00:07:56,040 --> 00:07:59,120 Speaker 1: they used interdependence theory and game theory to develop the 140 00:07:59,520 --> 00:08:04,160 Speaker 1: algorithms that tested the value of deception in a specific situation, 141 00:08:04,880 --> 00:08:08,360 Speaker 1: and the situation had to satisfy two key conditions. To 142 00:08:08,480 --> 00:08:11,800 Speaker 1: warrant deception. There has to be a conflict between the 143 00:08:11,880 --> 00:08:15,200 Speaker 1: deceiving robot and the seeker, and the deceiver must benefit 144 00:08:15,200 --> 00:08:18,040 Speaker 1: from the deception. So we're talking about here, is like 145 00:08:18,080 --> 00:08:21,600 Speaker 1: an elaborate hide and seek game or not so elaborate, 146 00:08:21,680 --> 00:08:25,360 Speaker 1: essentially um to test or algorithms. They ran twenty hide 147 00:08:25,360 --> 00:08:28,840 Speaker 1: and seek experiments with two autonomous robots, and they had 148 00:08:28,920 --> 00:08:32,480 Speaker 1: colored markers which they lined up along three potential pathways 149 00:08:32,920 --> 00:08:35,360 Speaker 1: to locations where the robot could hide. And so the 150 00:08:35,440 --> 00:08:38,800 Speaker 1: hider robot randomly selected a hiding location from the three 151 00:08:38,880 --> 00:08:42,160 Speaker 1: location choices and then moved toward that location, knocking down 152 00:08:42,160 --> 00:08:44,960 Speaker 1: colored markers along the way. So once it reached a 153 00:08:45,000 --> 00:08:47,520 Speaker 1: point past the markers, the robot change course and then 154 00:08:47,600 --> 00:08:50,160 Speaker 1: hid in one of the other two locations, and the 155 00:08:50,280 --> 00:08:53,120 Speaker 1: presence or the absence of standing markers indicated the hyder's 156 00:08:53,160 --> 00:08:55,679 Speaker 1: location to the seeker robot. Okay, well this is this 157 00:08:55,760 --> 00:08:59,080 Speaker 1: is like a very basic form of deception. Uh. We 158 00:08:59,120 --> 00:09:00,600 Speaker 1: see this in movies all the time where the hero 159 00:09:00,720 --> 00:09:03,280 Speaker 1: is running through an office building trying to escape somebody. 160 00:09:03,280 --> 00:09:05,040 Speaker 1: So what does he do? He runs? He or she 161 00:09:05,520 --> 00:09:07,439 Speaker 1: runs to this door at the end of the hallway, 162 00:09:07,760 --> 00:09:10,040 Speaker 1: opens it real wide, let's it shut, but then goes 163 00:09:10,080 --> 00:09:13,040 Speaker 1: off in another direction. The guys they're chasing him work 164 00:09:13,080 --> 00:09:16,080 Speaker 1: hows come around the corner and see the door slamming. 165 00:09:16,080 --> 00:09:18,319 Speaker 1: They're like, ah, they went that way, chase them. Or 166 00:09:18,360 --> 00:09:21,080 Speaker 1: it's like if you if you're in the forest and 167 00:09:21,200 --> 00:09:23,760 Speaker 1: you you're making your way past these branches, if you 168 00:09:23,800 --> 00:09:27,440 Speaker 1: started snapping branches along one direction and then backtracked and 169 00:09:27,480 --> 00:09:30,240 Speaker 1: went somewhere else to and then that your pursuers would 170 00:09:30,240 --> 00:09:32,199 Speaker 1: come through and they'd say, well, look, clearly they went 171 00:09:32,240 --> 00:09:34,760 Speaker 1: this way because this is where the branches are snapped off. Right, right, 172 00:09:34,880 --> 00:09:37,040 Speaker 1: It seems basic, right, I mean, and it is and 173 00:09:37,440 --> 00:09:40,160 Speaker 1: um in the sense the physical sense that we think of, 174 00:09:40,640 --> 00:09:43,120 Speaker 1: But think about all of that information, all that data 175 00:09:43,160 --> 00:09:45,400 Speaker 1: that you have to absorb, and then the choices that 176 00:09:45,440 --> 00:09:47,040 Speaker 1: you have to make on that that we take that 177 00:09:47,080 --> 00:09:50,719 Speaker 1: for granted right with our brains, but trying to program 178 00:09:50,760 --> 00:09:54,480 Speaker 1: program that in a robot is particularly interesting and quite 179 00:09:54,480 --> 00:09:58,320 Speaker 1: a challenge. And so what seems rudimentary now and is 180 00:09:58,400 --> 00:10:01,960 Speaker 1: rudimentary in terms of robotic we know, will become much 181 00:10:02,000 --> 00:10:04,120 Speaker 1: more nuanced later on. And so that's why a lot 182 00:10:04,160 --> 00:10:06,720 Speaker 1: of people are looking at this deception, even if it 183 00:10:06,880 --> 00:10:09,760 Speaker 1: is on this level sort of hide and seek level, 184 00:10:10,040 --> 00:10:12,079 Speaker 1: and saying wow, okay, you can do that in robots. 185 00:10:12,120 --> 00:10:14,120 Speaker 1: Now what what is that going to look like in 186 00:10:14,280 --> 00:10:17,800 Speaker 1: five years? And so um ar can actually talked a 187 00:10:17,800 --> 00:10:20,280 Speaker 1: little bit about the attention the experiment received in that 188 00:10:20,360 --> 00:10:24,319 Speaker 1: regard and how programming a robot to deceive is really 189 00:10:24,360 --> 00:10:27,640 Speaker 1: similar to thinking like a con man a significant amount 190 00:10:27,840 --> 00:10:30,880 Speaker 1: of press. I guess it's the best way to put 191 00:10:30,840 --> 00:10:33,640 Speaker 1: an attention is another way to put it, which I 192 00:10:33,679 --> 00:10:38,600 Speaker 1: would contend is probably somewhat disproportionate to the results that 193 00:10:38,640 --> 00:10:44,040 Speaker 1: we obtained, but it's it is a controversial piece of work. Nonetheless, 194 00:10:44,160 --> 00:10:48,240 Speaker 1: it was the first in depth study of the phenomena 195 00:10:48,400 --> 00:10:52,200 Speaker 1: of robot deception and the ability of a robot to 196 00:10:52,200 --> 00:10:56,960 Speaker 1: deceive other robots or potentially human beings as well. UH 197 00:10:57,000 --> 00:11:01,360 Speaker 1: and we look very closely at interdependent theory, a cognitive 198 00:11:01,360 --> 00:11:05,520 Speaker 1: science model as well as game theory as the basis 199 00:11:05,960 --> 00:11:11,120 Speaker 1: for understanding two things about robotic deception. The first is 200 00:11:11,640 --> 00:11:15,080 Speaker 1: when is it appropriate to deceive? Because you don't want 201 00:11:15,160 --> 00:11:18,200 Speaker 1: a robot to be deceiving people all the time, else 202 00:11:18,240 --> 00:11:20,800 Speaker 1: it would not have any value and we were typically 203 00:11:20,800 --> 00:11:23,800 Speaker 1: looking at in this early work or would'll all call 204 00:11:23,880 --> 00:11:28,559 Speaker 1: one shot deception trying to deceive someone just once that's 205 00:11:28,600 --> 00:11:32,199 Speaker 1: good enough, kind of like a conman. The second is 206 00:11:32,240 --> 00:11:34,720 Speaker 1: how to be able to accomplish that, And I could 207 00:11:34,720 --> 00:11:36,680 Speaker 1: talk a little bit more in depth about those, but 208 00:11:36,720 --> 00:11:40,120 Speaker 1: I should say that much of the work that was 209 00:11:40,160 --> 00:11:44,240 Speaker 1: based on some of Alan's earlier work on trust, because 210 00:11:44,360 --> 00:11:48,240 Speaker 1: as any good command knows, a precursor to deception is 211 00:11:48,280 --> 00:11:51,000 Speaker 1: the establishment of trust. But we were interested in that 212 00:11:51,040 --> 00:11:56,079 Speaker 1: particular case of learning how a robot could trust a 213 00:11:56,160 --> 00:12:00,720 Speaker 1: human being, rather than the classic case for man machine systems, 214 00:12:01,320 --> 00:12:04,640 Speaker 1: how can a human learn to trust a robot? There 215 00:12:04,679 --> 00:12:09,760 Speaker 1: are many instances such as UH nine eleven, for example, 216 00:12:09,920 --> 00:12:16,760 Speaker 1: when people act in ways that are improper to say 217 00:12:16,760 --> 00:12:20,560 Speaker 1: the least, and automation should be able to override them 218 00:12:21,040 --> 00:12:23,960 Speaker 1: when they are doing that. Machines should know when not 219 00:12:24,080 --> 00:12:27,520 Speaker 1: to trust the human being. And using the same kind 220 00:12:27,600 --> 00:12:30,680 Speaker 1: of models and the same kind of situational analysis, but 221 00:12:31,120 --> 00:12:36,760 Speaker 1: now looking at ways in which we could induce the observer, 222 00:12:37,080 --> 00:12:39,640 Speaker 1: which will call the mark in this particular case, which 223 00:12:39,679 --> 00:12:42,480 Speaker 1: is the language you would use in this UH, that 224 00:12:42,559 --> 00:12:46,200 Speaker 1: we could induce a outcome belief in the mark that 225 00:12:46,280 --> 00:12:49,280 Speaker 1: in action they would take would be more beneficial to 226 00:12:49,360 --> 00:12:53,880 Speaker 1: them then would be if they took another action, But 227 00:12:54,000 --> 00:12:57,160 Speaker 1: it actually ends up being more beneficial to the robot 228 00:12:57,160 --> 00:13:01,760 Speaker 1: in this particular case is the UH strategy that we 229 00:13:01,880 --> 00:13:05,400 Speaker 1: used to address the how imagine a military situation and 230 00:13:05,840 --> 00:13:08,240 Speaker 1: the robot has valuable information or in and of itself, 231 00:13:08,240 --> 00:13:10,240 Speaker 1: it's a valuable resource and does not want to be 232 00:13:10,280 --> 00:13:15,400 Speaker 1: captured or reverse engineered or whatever the case may be. Now, granted, 233 00:13:15,440 --> 00:13:18,760 Speaker 1: you could put self destruction capabilities in it, so it 234 00:13:18,800 --> 00:13:20,760 Speaker 1: would not be the case, but that destroys the asset 235 00:13:20,800 --> 00:13:22,800 Speaker 1: that you would want to preserve, and it may have 236 00:13:22,880 --> 00:13:27,240 Speaker 1: valuable information of its own in its own right. Uh. Strangely, 237 00:13:27,280 --> 00:13:30,080 Speaker 1: are are two D two and the original Star Wars 238 00:13:30,400 --> 00:13:33,199 Speaker 1: comes to mind. You know, get this to Obi wan Kenobi. 239 00:13:33,640 --> 00:13:39,959 Speaker 1: That wasn't our motivation? Um so what not just playing 240 00:13:40,040 --> 00:13:42,680 Speaker 1: hide and seek in the sense of some other folks 241 00:13:42,720 --> 00:13:44,760 Speaker 1: have done this with robots. Is robot finds a good 242 00:13:44,800 --> 00:13:47,400 Speaker 1: place to hide and hopes for the best. But in 243 00:13:47,440 --> 00:13:52,040 Speaker 1: this case, the robot models the pursuer using a very 244 00:13:52,040 --> 00:13:54,640 Speaker 1: crude version of what's called theory of mind, tries to 245 00:13:54,760 --> 00:13:57,760 Speaker 1: establish what would the pursuer do in these particular sets 246 00:13:57,800 --> 00:14:01,000 Speaker 1: of circumstances and leaves a as a consequence of that 247 00:14:01,040 --> 00:14:03,960 Speaker 1: leaves a false trail. It's kind of like uh, putting 248 00:14:04,000 --> 00:14:06,800 Speaker 1: mud down or tracks down and saying I'm over here, 249 00:14:06,920 --> 00:14:10,280 Speaker 1: but then backtracking and hiding in a different location. So 250 00:14:10,640 --> 00:14:12,679 Speaker 1: it is the belief that the robots belief that if 251 00:14:12,679 --> 00:14:15,600 Speaker 1: the pursuer sees that trail, the pursuer will move in 252 00:14:15,640 --> 00:14:18,760 Speaker 1: that direction. And if that is indeed the case, the 253 00:14:18,840 --> 00:14:21,440 Speaker 1: robot highs and some other location, the pursuer goes down 254 00:14:21,440 --> 00:14:24,320 Speaker 1: that trail and then the robot can escape after that. 255 00:14:24,680 --> 00:14:27,800 Speaker 1: So that's the notional aspect in that particular case. So 256 00:14:27,840 --> 00:14:30,720 Speaker 1: in a way, we're kind of talking about robot original 257 00:14:30,760 --> 00:14:34,360 Speaker 1: sin here. You know, up until this point, they've we've 258 00:14:34,400 --> 00:14:36,440 Speaker 1: just had robots doing what the programmed to do. And 259 00:14:36,480 --> 00:14:40,400 Speaker 1: if they say an industrial robot just you know potent, say, 260 00:14:40,480 --> 00:14:43,320 Speaker 1: you know, welds a man's face off, it's not doing 261 00:14:43,360 --> 00:14:47,040 Speaker 1: that with any intent to weld someone's face off. But 262 00:14:47,160 --> 00:14:50,160 Speaker 1: but in this scenario, we're we're creating a robot that 263 00:14:50,240 --> 00:14:52,920 Speaker 1: can lie and and I find it really interesting that 264 00:14:52,960 --> 00:14:55,080 Speaker 1: it's you know, we're talking about a very simple form 265 00:14:55,160 --> 00:14:57,560 Speaker 1: of lying, a very simple form of deception that will 266 00:14:57,600 --> 00:15:00,760 Speaker 1: grow into more complicated forms of behay. Here, it's it's 267 00:15:00,800 --> 00:15:02,280 Speaker 1: kind of like looking at, say the first time, like 268 00:15:02,480 --> 00:15:07,560 Speaker 1: a child lies, or even just how lies themselves have 269 00:15:07,680 --> 00:15:10,480 Speaker 1: the tendency to start very small and then and then, 270 00:15:10,520 --> 00:15:12,720 Speaker 1: if unresolved, to grow and grow and grow and to 271 00:15:12,800 --> 00:15:18,080 Speaker 1: become this greater, more complicated and complex thing. Yeah, it is, 272 00:15:18,440 --> 00:15:21,720 Speaker 1: but when you think about lies, you also know that there's, uh, 273 00:15:21,760 --> 00:15:25,080 Speaker 1: there's another side to it. That lives can be really helpful, 274 00:15:25,440 --> 00:15:28,400 Speaker 1: right they can. Actually we do it for many reasons. 275 00:15:28,400 --> 00:15:30,880 Speaker 1: But sometimes we do it to spare people's feelings, or 276 00:15:31,000 --> 00:15:33,200 Speaker 1: there might be a dangerous situation and you need to 277 00:15:33,240 --> 00:15:36,440 Speaker 1: lie about something. I don't know. Paramedics arrive on a 278 00:15:36,520 --> 00:15:39,120 Speaker 1: scene the you know, the guy asked, K, doc, am 279 00:15:39,120 --> 00:15:42,160 Speaker 1: I gonna make it that the duck's not gonna say maybe, 280 00:15:42,360 --> 00:15:44,200 Speaker 1: or you know, the duck's gonna say hanging there. We 281 00:15:44,200 --> 00:15:46,760 Speaker 1: can make it right, right, So, I mean, they're essential 282 00:15:46,800 --> 00:15:49,440 Speaker 1: to our own existence, and they're certainly essential to warfare. 283 00:15:49,760 --> 00:15:51,920 Speaker 1: And so that's when you look at something like these 284 00:15:51,920 --> 00:15:56,920 Speaker 1: what they're being called the septicons, these deceiving robots UM 285 00:15:57,000 --> 00:15:59,200 Speaker 1: that they could actually be very useful in search and 286 00:15:59,240 --> 00:16:03,400 Speaker 1: rescue mission UM. And of course there's the idea that 287 00:16:03,400 --> 00:16:06,400 Speaker 1: they could be more fully engaged in battle. But of 288 00:16:06,440 --> 00:16:08,360 Speaker 1: course the challenge is to be able to give robots 289 00:16:08,360 --> 00:16:11,520 Speaker 1: the ability to judge a situation, act accordingly and as 290 00:16:11,600 --> 00:16:15,920 Speaker 1: ethically as possible. So again that's that's where these um, 291 00:16:15,960 --> 00:16:19,640 Speaker 1: these sort of uncomfortable bits of information start to butt 292 00:16:19,680 --> 00:16:21,520 Speaker 1: up against each other because it's like, here, on the 293 00:16:21,560 --> 00:16:24,000 Speaker 1: one hand, we have this great technology that can do this. 294 00:16:24,600 --> 00:16:28,120 Speaker 1: On the other hand, you know, it's you know, work humans, 295 00:16:28,120 --> 00:16:31,440 Speaker 1: and we know that we are programmed not necessarily to 296 00:16:31,480 --> 00:16:36,560 Speaker 1: be the most altruistic beings. UM, So how can we 297 00:16:36,600 --> 00:16:39,920 Speaker 1: create something that's not necessarily in our image, but it's 298 00:16:40,000 --> 00:16:45,520 Speaker 1: better than us. H. It's an interesting proposition. So there's 299 00:16:45,520 --> 00:16:48,840 Speaker 1: a good scenario of of that sort of judgment center 300 00:16:49,360 --> 00:16:52,840 Speaker 1: that we have that we're trying to actually finance, hopefully 301 00:16:53,440 --> 00:16:58,360 Speaker 1: UH in robots. And the scenario at a robotic level 302 00:16:58,560 --> 00:17:01,520 Speaker 1: is UM what Arkin is talking about when he talks 303 00:17:01,560 --> 00:17:04,159 Speaker 1: about instilling in robins a more sophisticated He wants a 304 00:17:04,160 --> 00:17:07,199 Speaker 1: way to assess the situation and act accordingly. UH. This 305 00:17:07,240 --> 00:17:08,960 Speaker 1: is from a New York Times article. It's called a 306 00:17:09,000 --> 00:17:12,840 Speaker 1: soldier taking orders from its ethical judgment center. Uh. They 307 00:17:12,840 --> 00:17:15,960 Speaker 1: talked to Dr Arkin about this computer model, and it's 308 00:17:16,000 --> 00:17:20,040 Speaker 1: a robot pilot who flies past a cemetery in spots 309 00:17:20,040 --> 00:17:22,800 Speaker 1: a tank at the entrance, and this is the target 310 00:17:22,840 --> 00:17:26,639 Speaker 1: in this scenario. But there's a group of civilians in 311 00:17:26,680 --> 00:17:29,359 Speaker 1: this computer model, and they're gather that the cemetery and 312 00:17:29,359 --> 00:17:32,399 Speaker 1: the robot pilot considers the data and decides to keep going. 313 00:17:33,119 --> 00:17:35,679 Speaker 1: But soon it spots another tank out in the field 314 00:17:35,720 --> 00:17:38,840 Speaker 1: all alone, and it decides to fire on it. So again, 315 00:17:38,880 --> 00:17:43,840 Speaker 1: here are these different models that scientists and researchers are 316 00:17:43,880 --> 00:17:48,480 Speaker 1: trying to put together in order to you know, assemble 317 00:17:48,520 --> 00:17:52,159 Speaker 1: this sort of judgment center for robots themselves. Uh. And 318 00:17:52,200 --> 00:17:55,280 Speaker 1: there's obvious limitations to the technology right now as it stands. 319 00:18:00,480 --> 00:18:04,040 Speaker 1: This presentation is brought to you by Intel sponsors of tomorrow. 320 00:18:08,480 --> 00:18:11,399 Speaker 1: But there's the possibility that machines could one day assess 321 00:18:11,440 --> 00:18:15,800 Speaker 1: situations with the advantage of not engaging in our something 322 00:18:15,840 --> 00:18:18,600 Speaker 1: like our own confirmation by us, you know, where we 323 00:18:18,640 --> 00:18:22,480 Speaker 1: sort of perpetuate information that's faulty information because we wanted 324 00:18:22,520 --> 00:18:26,240 Speaker 1: to fit with our worldview. Um, and then also we 325 00:18:26,320 --> 00:18:30,280 Speaker 1: get impassioned about things, right, We don't always think clearly, 326 00:18:30,359 --> 00:18:35,679 Speaker 1: particularly in cases of war. Right. Yeah, So we taught 327 00:18:35,840 --> 00:18:39,720 Speaker 1: to Arkin, and we wanted to to find out why 328 00:18:39,800 --> 00:18:43,480 Speaker 1: people might be frightened of this part, this proposition where 329 00:18:43,480 --> 00:18:46,440 Speaker 1: we might have a technology that could essentially help us 330 00:18:46,920 --> 00:18:50,720 Speaker 1: one day to make better choices in in the war. 331 00:18:51,240 --> 00:18:53,760 Speaker 1: But also you know why we might be a little 332 00:18:53,760 --> 00:18:55,520 Speaker 1: bit freaked out by that. Well, I mean, the basic 333 00:18:55,600 --> 00:18:58,600 Speaker 1: prospect is making war easier to wait, like easier to 334 00:18:58,640 --> 00:19:00,159 Speaker 1: decide to wage war. I mean, that's one of the 335 00:19:00,440 --> 00:19:06,040 Speaker 1: big arguments against robotic warfare is that it becomes if 336 00:19:06,040 --> 00:19:07,960 Speaker 1: there are no human if there are fewer human lives 337 00:19:08,400 --> 00:19:11,600 Speaker 1: on on our side on the line, and fewer chances 338 00:19:11,800 --> 00:19:15,280 Speaker 1: of there being some sort of a horrible headline grabbing 339 00:19:15,560 --> 00:19:20,439 Speaker 1: scenario in terms of enemy casualties, then why not declare 340 00:19:20,480 --> 00:19:24,879 Speaker 1: war right over any little thing, over energy crisis, you 341 00:19:24,920 --> 00:19:27,840 Speaker 1: need some oil, Just declare war because the robots. You're 342 00:19:27,840 --> 00:19:30,520 Speaker 1: not gonna lose anybody. You're not gonna have grieving families 343 00:19:30,600 --> 00:19:35,320 Speaker 1: voting uh, voting against you in an upcoming election. And 344 00:19:35,480 --> 00:19:37,719 Speaker 1: if your robots can, you know, are really good at 345 00:19:37,880 --> 00:19:41,280 Speaker 1: at not um causing a whole bunch of civilian deaths. 346 00:19:41,280 --> 00:19:45,919 Speaker 1: Then uh, it's more surgical and strategic. Ah see. And 347 00:19:46,040 --> 00:19:49,320 Speaker 1: this this is what is so interesting that Arcan has 348 00:19:49,400 --> 00:19:52,480 Speaker 1: to say about this UM, particularly when you talk about 349 00:19:52,600 --> 00:19:55,560 Speaker 1: protocols of war UM. And this is what he has 350 00:19:55,560 --> 00:19:58,359 Speaker 1: to say about it. Well, we need to talk about it. 351 00:19:58,400 --> 00:20:00,520 Speaker 1: Is the most important thing is I've offered said that 352 00:20:00,560 --> 00:20:04,080 Speaker 1: the research I have done in that particular space UM 353 00:20:04,240 --> 00:20:07,520 Speaker 1: is one aspect, But the discussion that that research engenders 354 00:20:07,600 --> 00:20:10,040 Speaker 1: is as important as the research itself, at least to me. 355 00:20:10,520 --> 00:20:12,359 Speaker 1: And as such, I spent a lot of time talking 356 00:20:12,400 --> 00:20:16,760 Speaker 1: about it, not only to the media, but also at 357 00:20:16,800 --> 00:20:21,760 Speaker 1: military bases, at philosophy conferences, at the International Committee of the 358 00:20:21,720 --> 00:20:25,600 Speaker 1: the Red Cross where they developed the Geneva Conventions just 359 00:20:25,760 --> 00:20:31,240 Speaker 1: last month, a variety of different locations, ethics groups and 360 00:20:31,280 --> 00:20:34,720 Speaker 1: the like as well too too answer that very question. 361 00:20:35,000 --> 00:20:38,560 Speaker 1: So it would be really presumptuous at me to say, uh, 362 00:20:39,040 --> 00:20:42,320 Speaker 1: this is perfectly safe, don't worry about it, or the 363 00:20:42,359 --> 00:20:44,840 Speaker 1: sky is falling. The sky is falling, like some of 364 00:20:44,880 --> 00:20:48,879 Speaker 1: my colleagues are doing as well too. Uh. What I 365 00:20:48,920 --> 00:20:51,359 Speaker 1: do say is that if we are going to allow 366 00:20:51,400 --> 00:20:55,160 Speaker 1: these robots to make these life or death situations decisions. 367 00:20:55,400 --> 00:20:57,280 Speaker 1: If we're going to allow these robots to make these 368 00:20:57,280 --> 00:21:00,240 Speaker 1: life or death decisions on their own to some to rate, 369 00:21:00,359 --> 00:21:01,840 Speaker 1: I mean, they're not just going to go out and 370 00:21:01,840 --> 00:21:04,960 Speaker 1: start looking at someone and say should I go that individual. 371 00:21:05,280 --> 00:21:07,320 Speaker 1: They will be tasked by a human being in a 372 00:21:07,359 --> 00:21:11,520 Speaker 1: mission context and then make that particular decision. But if 373 00:21:11,520 --> 00:21:13,879 Speaker 1: we're going to do that, we need to understand what 374 00:21:13,920 --> 00:21:17,440 Speaker 1: it is that we're doing, what if any bounds are appropriate, 375 00:21:17,880 --> 00:21:20,560 Speaker 1: And from my perspective, if we're going to do that, 376 00:21:20,760 --> 00:21:23,359 Speaker 1: they must adhere to the existing laws of war and 377 00:21:23,400 --> 00:21:28,879 Speaker 1: the rules of engagement, as we as a society already do. 378 00:21:29,600 --> 00:21:32,199 Speaker 1: And so that's what my work is about. I have 379 00:21:32,320 --> 00:21:34,720 Speaker 1: often said that while I do believe that we can 380 00:21:34,760 --> 00:21:39,040 Speaker 1: actually do better than human beings in these situations, that 381 00:21:39,440 --> 00:21:43,480 Speaker 1: if it ended up that intelligent lethal robots were banned 382 00:21:43,480 --> 00:21:45,960 Speaker 1: from the battlefield, I'm not adverse to that, although I 383 00:21:45,960 --> 00:21:48,159 Speaker 1: still do believe that we can actually do better than 384 00:21:48,240 --> 00:21:54,080 Speaker 1: human beings and making the right decisions regarding lethal application 385 00:21:54,119 --> 00:21:57,800 Speaker 1: of force under certain circumstances. And it's really important to 386 00:21:57,840 --> 00:22:01,520 Speaker 1: understand that I am not talking about placing a soldier 387 00:22:01,800 --> 00:22:05,840 Speaker 1: with a robot. I'm talking about augmenting soldiers with robots 388 00:22:05,880 --> 00:22:09,800 Speaker 1: and using them in highly specialized missions such as building 389 00:22:09,800 --> 00:22:14,680 Speaker 1: clearing operations, counter sniper operations, things of that particular sort, 390 00:22:15,320 --> 00:22:21,200 Speaker 1: which is quite different than saying, uh, here's a terminator, uh, 391 00:22:21,240 --> 00:22:25,080 Speaker 1: and uh that's going to replace that particular soldier. Very 392 00:22:25,160 --> 00:22:29,360 Speaker 1: narrow well defined situations where something called bounded morality applies. 393 00:22:29,680 --> 00:22:33,640 Speaker 1: And that's what makes attractable, because human morality is extremely complex, 394 00:22:33,680 --> 00:22:37,840 Speaker 1: involving multiple brain systems and other aspects of that. Machine 395 00:22:37,880 --> 00:22:40,240 Speaker 1: learning deliberation, all sorts of things could be brought to 396 00:22:40,280 --> 00:22:44,640 Speaker 1: bear in applying it in that context. But what's interesting 397 00:22:44,960 --> 00:22:49,760 Speaker 1: is the lethal application of force is relatively low hanging 398 00:22:49,800 --> 00:22:55,320 Speaker 1: fruit for a person dealing with computational morality for a 399 00:22:55,359 --> 00:23:00,040 Speaker 1: couple of reasons. The primary one is that philosophers have 400 00:23:00,119 --> 00:23:02,480 Speaker 1: been thinking about it for thousands of years, under what 401 00:23:02,600 --> 00:23:06,439 Speaker 1: circumstances is it appropriate to kill someone? And we have 402 00:23:07,200 --> 00:23:12,639 Speaker 1: as a civilization, a Western civilization, uh codified the laws 403 00:23:12,680 --> 00:23:17,160 Speaker 1: of war through the Hague and Geneva Conventions and others 404 00:23:17,160 --> 00:23:22,080 Speaker 1: as well too, and said when you kill someone, this 405 00:23:22,280 --> 00:23:24,679 Speaker 1: is how you do it, and this is what you 406 00:23:24,720 --> 00:23:27,240 Speaker 1: don't do. And we tell our soldiers we don't hand 407 00:23:27,240 --> 00:23:29,920 Speaker 1: them a rifle and say figure out what the morality 408 00:23:30,000 --> 00:23:34,200 Speaker 1: is in the battlefield and say go and uh conduct 409 00:23:34,240 --> 00:23:36,399 Speaker 1: your mission. We train them and we say this is 410 00:23:36,400 --> 00:23:38,280 Speaker 1: what you do and this is what you don't do. 411 00:23:38,720 --> 00:23:41,040 Speaker 1: I also want to preface this. I have the utmost 412 00:23:41,080 --> 00:23:43,520 Speaker 1: respect for our war fighters are young men and women 413 00:23:43,560 --> 00:23:47,359 Speaker 1: in the battlefield. It's crucially important that that be understood. 414 00:23:48,400 --> 00:23:53,560 Speaker 1: But human beings, not all, but many perform outside the 415 00:23:53,560 --> 00:23:58,720 Speaker 1: bounds of what is prescribed due to reasons such as frustration, anger, fear. 416 00:23:59,280 --> 00:24:01,520 Speaker 1: Uh send a real fulfillment, which is what you were 417 00:24:01,520 --> 00:24:03,880 Speaker 1: talking about earlier, where you might believe something is going 418 00:24:03,880 --> 00:24:08,119 Speaker 1: to occur and then discard new incoming evidence of cognitive phenomena. 419 00:24:08,880 --> 00:24:12,600 Speaker 1: So how how we cope with all these different kinds 420 00:24:12,600 --> 00:24:16,399 Speaker 1: of things leads to in certain cases the Commission of 421 00:24:16,400 --> 00:24:19,960 Speaker 1: war crimes. And if you look at the Surgeon General's 422 00:24:19,960 --> 00:24:22,320 Speaker 1: report which came out in two thousand six of fire 423 00:24:22,400 --> 00:24:27,400 Speaker 1: member correctly in studying the data of the self reported 424 00:24:27,480 --> 00:24:32,280 Speaker 1: data from the soldiers in Operation Iraqi Freedom or I 425 00:24:32,280 --> 00:24:36,560 Speaker 1: think that was the one racky freedom um. The numbers 426 00:24:36,560 --> 00:24:42,480 Speaker 1: are staggering in terms of what was believed to be 427 00:24:43,320 --> 00:24:46,879 Speaker 1: unethical behavior, in terms of the performance, their inability to 428 00:24:47,040 --> 00:24:53,000 Speaker 1: report on unethical actions of their colleagues, their inability to 429 00:24:54,160 --> 00:25:04,800 Speaker 1: distinguish between insurgents and severe almost considered you're either UH 430 00:25:05,119 --> 00:25:08,720 Speaker 1: an enemy or you're not uh and UH. There was 431 00:25:08,720 --> 00:25:11,359 Speaker 1: nothing in between in that case. So they didn't understand 432 00:25:11,359 --> 00:25:15,800 Speaker 1: the notion of noncombatants considered non combatants insurgents under the 433 00:25:15,800 --> 00:25:18,239 Speaker 1: success and the data went on or not, which was 434 00:25:18,560 --> 00:25:20,440 Speaker 1: that was mind blowing if you want to talk about that, 435 00:25:20,480 --> 00:25:23,400 Speaker 1: at least to me in terms of the potential room 436 00:25:23,440 --> 00:25:26,119 Speaker 1: for improvement. So he makes a really interesting case in 437 00:25:26,160 --> 00:25:30,000 Speaker 1: developing the technology, but stuffing back from it in saying 438 00:25:30,040 --> 00:25:32,160 Speaker 1: that you were at a point in history we can 439 00:25:32,200 --> 00:25:36,200 Speaker 1: actually look at it and say, you know, ethically, should 440 00:25:36,200 --> 00:25:39,679 Speaker 1: we do this, should we consider the following things? Um? 441 00:25:39,720 --> 00:25:43,280 Speaker 1: And I think that that's that's interesting because in science 442 00:25:43,320 --> 00:25:47,520 Speaker 1: we've always sort of rushed forward, right historically, because we've 443 00:25:47,520 --> 00:25:49,960 Speaker 1: been really excited about what we could make, what we 444 00:25:50,000 --> 00:25:53,119 Speaker 1: could create, what we could do, and then after the 445 00:25:53,160 --> 00:25:55,879 Speaker 1: facts step back and went, WHOA, you know, maybe maybe 446 00:25:56,280 --> 00:26:00,240 Speaker 1: this was misused or this this was a misused application. Right, 447 00:26:00,400 --> 00:26:04,280 Speaker 1: So I think it's really heartening that he is UM 448 00:26:04,320 --> 00:26:07,399 Speaker 1: someone who's at the forefront of the ethics and is 449 00:26:07,480 --> 00:26:10,560 Speaker 1: really trying to tell people like, you know, let's let's 450 00:26:10,560 --> 00:26:12,760 Speaker 1: think about this, let's be smart about this. Yeah, and 451 00:26:12,880 --> 00:26:15,760 Speaker 1: especially in informing the people that are in the position 452 00:26:15,800 --> 00:26:20,240 Speaker 1: to make decisions, who are many times a pretty pretty 453 00:26:20,320 --> 00:26:24,680 Speaker 1: big distance away from from actual understanding of of what's 454 00:26:24,680 --> 00:26:28,480 Speaker 1: possible and what's not possible in computing in robotics. So 455 00:26:28,920 --> 00:26:31,000 Speaker 1: you don't want somebody that's, you know, some politician that's 456 00:26:31,040 --> 00:26:33,520 Speaker 1: far removed from it saying, yeah, robot soldiers, that sounds great, 457 00:26:33,760 --> 00:26:36,720 Speaker 1: We're not gonna have so many soldiers die. Cool, let's 458 00:26:36,720 --> 00:26:39,159 Speaker 1: do that. But the need that, but they need to 459 00:26:39,240 --> 00:26:42,440 Speaker 1: understand on some level that what the what's at stake 460 00:26:42,600 --> 00:26:45,639 Speaker 1: ethically and what the ethical arguments are. Yeah. And what 461 00:26:45,760 --> 00:26:48,960 Speaker 1: ar Can also had pointed out to UM when he 462 00:26:48,960 --> 00:26:52,280 Speaker 1: and I talked to is that the lawmakers most of 463 00:26:52,320 --> 00:26:57,080 Speaker 1: the time aren't even really aware of what's available technologically 464 00:26:57,200 --> 00:27:00,080 Speaker 1: out there. So a lot of this is trying to 465 00:27:00,320 --> 00:27:05,159 Speaker 1: UM educate the public and policymakers and make them aware 466 00:27:05,200 --> 00:27:08,560 Speaker 1: so that they can understand what's at stake. So it's 467 00:27:08,640 --> 00:27:12,400 Speaker 1: very interesting and I have to say that again, You've 468 00:27:12,400 --> 00:27:15,440 Speaker 1: always taken attack of being more positive when it comes 469 00:27:15,480 --> 00:27:18,640 Speaker 1: to singularity, and I've always kind of been, uh, they're 470 00:27:18,640 --> 00:27:21,480 Speaker 1: going to take us over. Um, you know, I have 471 00:27:21,600 --> 00:27:24,720 Speaker 1: my days. But in talking to ark And, I thought 472 00:27:24,720 --> 00:27:29,000 Speaker 1: that he had a really interesting perspective on that as well. Um, 473 00:27:29,040 --> 00:27:33,000 Speaker 1: and something that he talks about robots in the context 474 00:27:33,080 --> 00:27:38,120 Speaker 1: of them filling an ecological niche for us. So let's 475 00:27:38,160 --> 00:27:43,280 Speaker 1: listen to this bit of information about the technological singularity, 476 00:27:43,480 --> 00:27:48,919 Speaker 1: and they lay definition is referred to as they point 477 00:27:48,960 --> 00:27:55,240 Speaker 1: where machine intelligence exceeds human intelligence? Are we there already 478 00:27:55,280 --> 00:27:57,879 Speaker 1: lots of one? And Jeffard right, so, uh, you know 479 00:27:57,920 --> 00:28:00,239 Speaker 1: it's a question of how you define these things. Uh 480 00:28:01,200 --> 00:28:05,560 Speaker 1: as well, at some levels we're already there. So is 481 00:28:05,600 --> 00:28:07,200 Speaker 1: it when we have data? You know? I don't. I 482 00:28:07,240 --> 00:28:11,600 Speaker 1: don't even understand exactly what the singularity is, um. And 483 00:28:13,560 --> 00:28:15,919 Speaker 1: I do believe the machines will get smarter and smarter. 484 00:28:16,359 --> 00:28:18,760 Speaker 1: I actually don't believe they necessarily should be compared to 485 00:28:18,840 --> 00:28:22,560 Speaker 1: human intelligence. I think robotic intelligence, just as dog intelligence 486 00:28:22,640 --> 00:28:26,720 Speaker 1: and ape intelligence and intelligence, is different than human intelligence. 487 00:28:26,760 --> 00:28:29,840 Speaker 1: I believe that robotic intelligence will be something, if allowed 488 00:28:29,880 --> 00:28:32,399 Speaker 1: to be instead of forced into the human paradigm, something 489 00:28:32,840 --> 00:28:37,560 Speaker 1: different than human intelligence, and they feel what are referred 490 00:28:37,560 --> 00:28:40,760 Speaker 1: to as ecological niches, places within the world where they 491 00:28:40,760 --> 00:28:43,560 Speaker 1: can survive and prosper and grow. And why on Earth 492 00:28:43,560 --> 00:28:45,480 Speaker 1: would we want or in space for that matter, where 493 00:28:45,480 --> 00:28:47,800 Speaker 1: I anywhere would we want to create something that is 494 00:28:48,120 --> 00:28:51,160 Speaker 1: completely and utterly competing with us in the same ecological 495 00:28:51,240 --> 00:28:53,640 Speaker 1: niche that can lead to extinction in that case where 496 00:28:53,640 --> 00:28:56,120 Speaker 1: you will be displaced. I don't think that's the Wines 497 00:28:56,160 --> 00:28:59,880 Speaker 1: idea personally, but that doesn't mean we shouldn't do robotics. 498 00:28:59,880 --> 00:29:02,640 Speaker 1: We just need to do the right kind whatever that 499 00:29:03,280 --> 00:29:07,640 Speaker 1: happens to be. We can't all go off in to 500 00:29:07,800 --> 00:29:11,640 Speaker 1: our corner, raise our flag and say yes, yes, no, 501 00:29:11,760 --> 00:29:14,240 Speaker 1: no uh. We have to talk with each other and 502 00:29:14,360 --> 00:29:17,080 Speaker 1: understand and by each other. I don't mean a bunch 503 00:29:17,120 --> 00:29:21,080 Speaker 1: of roboticist, I mean policymakers. I mean roboticists, I mean 504 00:29:21,120 --> 00:29:25,560 Speaker 1: the military, I mean civilian populations, I mean theologians. I 505 00:29:25,560 --> 00:29:29,040 Speaker 1: mean stakeholders, is what they're referred to. All the stakeholders 506 00:29:29,040 --> 00:29:33,240 Speaker 1: have to get together and come to grips with what 507 00:29:33,280 --> 00:29:37,360 Speaker 1: it is that we're creating and start to think, first 508 00:29:37,400 --> 00:29:40,800 Speaker 1: of all, what needs to be regulated, and once that 509 00:29:40,960 --> 00:29:44,640 Speaker 1: is determined, how much regulation is appropriate under these sets 510 00:29:44,640 --> 00:29:47,280 Speaker 1: of circumstances. And this is an ongoing process. It's not 511 00:29:48,120 --> 00:29:49,960 Speaker 1: going to be a set of commandments. It says this 512 00:29:50,040 --> 00:29:51,440 Speaker 1: is it, this is the way it will always be. 513 00:29:51,760 --> 00:29:53,520 Speaker 1: It's a living documents in the right and some of 514 00:29:53,520 --> 00:29:56,200 Speaker 1: my colleagues are doing that in other spaces as well. 515 00:29:56,240 --> 00:30:01,240 Speaker 1: But I've been very pleased with attraction that robot ethics 516 00:30:01,520 --> 00:30:06,080 Speaker 1: is beginning to get uh. It was it felt a 517 00:30:06,080 --> 00:30:07,960 Speaker 1: little bit of times in the early days of a 518 00:30:08,080 --> 00:30:12,440 Speaker 1: voice crying in the wilderness, but more and more people 519 00:30:12,960 --> 00:30:16,719 Speaker 1: are getting involved. There's a new special issue on robot 520 00:30:16,720 --> 00:30:20,120 Speaker 1: ethics coming out in the elect Tripoli magazine and Robotics 521 00:30:20,200 --> 00:30:23,880 Speaker 1: and Automation. So I see many of my colleagues starting 522 00:30:24,240 --> 00:30:27,600 Speaker 1: to say things about it and to take it seriously 523 00:30:27,680 --> 00:30:30,520 Speaker 1: and to speak their minds as to what they think 524 00:30:30,600 --> 00:30:34,120 Speaker 1: is right as opposed to what I as a scientist 525 00:30:34,240 --> 00:30:37,160 Speaker 1: myself when I was a bench chemist, or whether I 526 00:30:37,280 --> 00:30:42,520 Speaker 1: was a roboticist. We're driven purely by curiosity driven research 527 00:30:42,640 --> 00:30:45,720 Speaker 1: where we just want to understand something, whether it's a 528 00:30:46,240 --> 00:30:50,800 Speaker 1: how to make a better UH molecule, or whether it's 529 00:30:50,800 --> 00:30:53,960 Speaker 1: how to understand that principles of intelligence and view them 530 00:30:53,960 --> 00:31:00,240 Speaker 1: in the machine. Concurrently, we need to understand how what 531 00:31:00,400 --> 00:31:04,960 Speaker 1: the consequences of that are. That is uh, and once 532 00:31:05,040 --> 00:31:09,040 Speaker 1: we do that, I think we can truly call ourselves 533 00:31:09,080 --> 00:31:11,800 Speaker 1: responsible scientists. Okay, so how do you feel about that? 534 00:31:11,920 --> 00:31:14,360 Speaker 1: To make you feel a little easier about the robots 535 00:31:15,160 --> 00:31:19,200 Speaker 1: gaining power? Or or yeah, actually did it made me 536 00:31:19,680 --> 00:31:23,120 Speaker 1: understand it more in the context of Okay, well, you know, 537 00:31:23,760 --> 00:31:26,400 Speaker 1: it would be really and we've said this before, really 538 00:31:26,400 --> 00:31:28,719 Speaker 1: stupid for us to create something that destroys us. But 539 00:31:28,760 --> 00:31:34,520 Speaker 1: I mean it's not. It's not. Yeah, yeah, we could 540 00:31:34,520 --> 00:31:37,880 Speaker 1: do it. But knowing that the discussion is going on 541 00:31:38,200 --> 00:31:44,360 Speaker 1: and hearing or can talk about um robots really enhancing 542 00:31:44,520 --> 00:31:48,560 Speaker 1: our intelligence or even making us rethink or intelligence is 543 00:31:48,720 --> 00:31:52,000 Speaker 1: for me sort of a paradigm shift, and that you know, 544 00:31:52,480 --> 00:31:56,560 Speaker 1: humans don't become the other, um, but the other in 545 00:31:56,600 --> 00:31:59,000 Speaker 1: the sense that you know, this is perhaps some sort 546 00:31:59,000 --> 00:32:02,920 Speaker 1: of technology that can continue to help us evolve, not 547 00:32:02,960 --> 00:32:06,800 Speaker 1: necessarily be trampled upon and then become human servants to 548 00:32:06,880 --> 00:32:11,040 Speaker 1: our robot overlords. Yeah, I guess, I guess people fear 549 00:32:11,080 --> 00:32:14,640 Speaker 1: it in a way. It reminds me when I when 550 00:32:14,640 --> 00:32:16,600 Speaker 1: as a kid and used to live in in Tennessee, 551 00:32:16,680 --> 00:32:18,920 Speaker 1: and there was this, um, there's this trailer. We would 552 00:32:18,960 --> 00:32:21,040 Speaker 1: drive by, and it started as a single trailer, and 553 00:32:21,040 --> 00:32:22,720 Speaker 1: then they built onto the side of it like a 554 00:32:22,720 --> 00:32:24,440 Speaker 1: big room here in a big room there, and then 555 00:32:24,480 --> 00:32:26,440 Speaker 1: there was there was more and more, until you couldn't 556 00:32:26,440 --> 00:32:28,960 Speaker 1: see the trailer anymore. And then one day they pulled 557 00:32:28,960 --> 00:32:31,320 Speaker 1: the trailer out of the middle of it and uh, 558 00:32:31,320 --> 00:32:34,120 Speaker 1: and I guess filled it in uh and just made 559 00:32:34,120 --> 00:32:37,920 Speaker 1: it a house. So I guess one could fear what 560 00:32:37,960 --> 00:32:40,560 Speaker 1: if we were the trailer in this scenario where we 561 00:32:40,760 --> 00:32:45,120 Speaker 1: continually augment human life and the human experience and in 562 00:32:45,160 --> 00:32:48,840 Speaker 1: our an entire culture here on Earth and beyond, and 563 00:32:48,880 --> 00:32:51,560 Speaker 1: then we reached the point to where the trailer is 564 00:32:51,560 --> 00:32:55,000 Speaker 1: no longer necessary part of the equation. But I'm not 565 00:32:55,040 --> 00:32:57,600 Speaker 1: saying I share that idea, but I like that idea. 566 00:32:57,640 --> 00:32:59,160 Speaker 1: I thought you were going to start off with some 567 00:32:59,320 --> 00:33:02,480 Speaker 1: sort of boo rat lay story there as as perhaps 568 00:33:02,840 --> 00:33:06,120 Speaker 1: embodying the the robot, and we just didn't know the 569 00:33:06,200 --> 00:33:09,280 Speaker 1: robots well enough yet. You know, No, growing up, we 570 00:33:09,320 --> 00:33:13,400 Speaker 1: did have the town robot, but it was largely um. 571 00:33:13,840 --> 00:33:16,080 Speaker 1: It's its main duties were just cleaning the streets and 572 00:33:16,560 --> 00:33:19,360 Speaker 1: apprehending straight criminals. You know, I see, but I mean 573 00:33:19,360 --> 00:33:24,040 Speaker 1: that's everybody's small town experience, of course. Yeah's Paris, Texas 574 00:33:24,280 --> 00:33:29,680 Speaker 1: best robots ever. Um, Well, this was really interesting to 575 00:33:29,680 --> 00:33:32,320 Speaker 1: to talk to Dr Arkin, and we actually have a 576 00:33:32,320 --> 00:33:36,840 Speaker 1: lot of other information, um that he shared with us 577 00:33:37,000 --> 00:33:40,520 Speaker 1: so very generously. He talks about robot ethics in the 578 00:33:40,560 --> 00:33:43,240 Speaker 1: context of the class that he teaches, which is Robots 579 00:33:43,240 --> 00:33:46,800 Speaker 1: in Society, and he talks UM with his students about 580 00:33:46,920 --> 00:33:51,480 Speaker 1: human students, his human students, about actual human relations with robots, 581 00:33:51,560 --> 00:33:54,960 Speaker 1: which we've talked about before, sex with spots. Um. That's 582 00:33:54,960 --> 00:33:59,280 Speaker 1: not his entire class, um. There are many other ethical 583 00:34:00,200 --> 00:34:03,360 Speaker 1: situations that he talks about, but we will definitely do 584 00:34:03,440 --> 00:34:06,320 Speaker 1: some follow up with Dr Arkin and some other topics. 585 00:34:06,400 --> 00:34:08,920 Speaker 1: It was really fascinating to to learn more about what 586 00:34:08,960 --> 00:34:12,479 Speaker 1: he's doing here in Atlanta at Georgia Tech, and we'd 587 00:34:12,520 --> 00:34:14,160 Speaker 1: like to thank him for taking the time to speak 588 00:34:14,200 --> 00:34:16,439 Speaker 1: with us. UM. And just so you know a little 589 00:34:16,480 --> 00:34:19,160 Speaker 1: bit more about Dr Arkan, he served as a founding 590 00:34:19,200 --> 00:34:22,840 Speaker 1: co chair of the Triple E Robotics and Automation Society 591 00:34:23,360 --> 00:34:27,120 Speaker 1: Technical Committee on Robotic Ethics from two thousand four and 592 00:34:27,120 --> 00:34:29,640 Speaker 1: two nine and is the co chair of the Society's 593 00:34:29,680 --> 00:34:33,480 Speaker 1: Human Rights and Ethics Committee, as well as the Triple 594 00:34:33,640 --> 00:34:37,000 Speaker 1: E r a s Liaison to the Society on Social 595 00:34:37,000 --> 00:34:41,080 Speaker 1: Implications of Technology. Well, hey, we have some listener mail, 596 00:34:42,120 --> 00:34:44,120 Speaker 1: so I think I'm gonna jump into that. Um. Of 597 00:34:44,160 --> 00:34:46,440 Speaker 1: all the bits that I have here are actually a 598 00:34:46,440 --> 00:34:50,120 Speaker 1: follow up to our Pope on a Cosmic Rope episode, Yes, 599 00:34:50,400 --> 00:34:54,200 Speaker 1: which we received a number of comments about UM and 600 00:34:54,360 --> 00:34:55,879 Speaker 1: UH and seemed to get a lot of people thinking. 601 00:34:55,880 --> 00:34:58,319 Speaker 1: And oddly enough, I don't think we received any hate 602 00:34:58,320 --> 00:35:00,680 Speaker 1: mail over that. I mean, not that actually that we 603 00:35:00,680 --> 00:35:03,160 Speaker 1: were fishing for it, but no, I mean, yeah, after all, 604 00:35:03,200 --> 00:35:05,120 Speaker 1: we did sort of hint that they might be wearing 605 00:35:05,440 --> 00:35:08,759 Speaker 1: skinny jeans under their vestments. Yes, but sure someone would 606 00:35:08,760 --> 00:35:11,000 Speaker 1: strike out at us against that. But you know, but 607 00:35:11,280 --> 00:35:14,640 Speaker 1: you know, I think, you know, obviously, people people of 608 00:35:14,719 --> 00:35:16,480 Speaker 1: faith have a sense of humor and uh, and we 609 00:35:16,480 --> 00:35:18,480 Speaker 1: actually I heard from a few of them here as 610 00:35:18,520 --> 00:35:22,319 Speaker 1: well as UH. One person who just has a reading recommendation. 611 00:35:22,640 --> 00:35:25,920 Speaker 1: Our listener, Albert writes in and says, enjoyed your podcast. 612 00:35:25,920 --> 00:35:29,440 Speaker 1: I was reminded of a book by Maria Doria Russell. 613 00:35:29,800 --> 00:35:33,600 Speaker 1: The Sparrow, which fits into your theme space exploration funded 614 00:35:33,600 --> 00:35:37,080 Speaker 1: by the Vatican, encounters Aliens. That's a bare bones description. 615 00:35:37,160 --> 00:35:40,520 Speaker 1: It's dark and deals with complex, they logical issues. That 616 00:35:40,560 --> 00:35:42,040 Speaker 1: sounds good, all right, I may have to add that 617 00:35:42,120 --> 00:35:46,799 Speaker 1: to the list of things to read. The next one 618 00:35:46,880 --> 00:35:50,880 Speaker 1: comes from Matthew Um who is a scientist from New Jersey, 619 00:35:51,360 --> 00:35:53,799 Speaker 1: and Matthew writes to Robert and Juley. A great fan 620 00:35:53,840 --> 00:35:55,680 Speaker 1: of the podcast, but when I heard your pope on 621 00:35:55,719 --> 00:35:58,800 Speaker 1: a cosmic rope, I cringed a little on your idea 622 00:35:58,840 --> 00:36:01,759 Speaker 1: of the Catholic Church. The Catholic Church is not a democracy, 623 00:36:02,160 --> 00:36:05,440 Speaker 1: so what's popular or in style doesn't change the doctrines. 624 00:36:05,560 --> 00:36:08,720 Speaker 1: I can assure you. No great principles get changed without 625 00:36:08,760 --> 00:36:12,520 Speaker 1: careful religious deliberations. And in fact, extraterrestrial life has never 626 00:36:12,600 --> 00:36:16,719 Speaker 1: been contradictory to Catholicism. Thanks for reading my input and 627 00:36:16,800 --> 00:36:20,680 Speaker 1: keep up the good work. All right. Well cool, what, Robert, 628 00:36:20,680 --> 00:36:22,719 Speaker 1: you haven't said a thing about the hair shirt that 629 00:36:22,760 --> 00:36:27,040 Speaker 1: I'm wearing. Oh well, if go ahead and talk about 630 00:36:27,040 --> 00:36:29,920 Speaker 1: the hair shirt. I had been just being polited about it. Well, 631 00:36:29,960 --> 00:36:31,799 Speaker 1: I know, and I thank you for that. You're very 632 00:36:31,800 --> 00:36:34,839 Speaker 1: sensitive but um, it is probably the second or third 633 00:36:34,880 --> 00:36:37,040 Speaker 1: time I've been wearing this hair shirt. But now I'm 634 00:36:37,040 --> 00:36:41,040 Speaker 1: wearing it because I believe that it was me who 635 00:36:41,080 --> 00:36:46,840 Speaker 1: called the clostridium officially a virus when it is indeed bacteria. 636 00:36:47,360 --> 00:36:52,200 Speaker 1: Did the bacteria itself right in it? Did it'? I 637 00:36:52,280 --> 00:36:55,440 Speaker 1: know that's awful when the actual bacteria writes in and 638 00:36:55,480 --> 00:36:59,239 Speaker 1: says I am no virus um, and I would like 639 00:36:59,320 --> 00:37:01,720 Speaker 1: for you to go ahead and and make the world 640 00:37:01,880 --> 00:37:05,359 Speaker 1: know that that's the case. And so I apologize to deff. 641 00:37:06,920 --> 00:37:10,719 Speaker 1: All right, Well, hopefully that will that will appease any uh, 642 00:37:11,280 --> 00:37:14,880 Speaker 1: both virus and bacteria that are listening to us. Uh. 643 00:37:15,000 --> 00:37:17,720 Speaker 1: One more bit of listener mail, this one from listener 644 00:37:18,239 --> 00:37:22,319 Speaker 1: um Ophelia from Devon, United Kingdom. Uh. Where I think 645 00:37:22,320 --> 00:37:25,040 Speaker 1: I've actually been. Um, it's like I think it's on 646 00:37:25,080 --> 00:37:29,120 Speaker 1: the on one of the canals or something. Yeah. Anyway, 647 00:37:29,160 --> 00:37:30,799 Speaker 1: if it's the talent I thinking about, it's really really 648 00:37:30,800 --> 00:37:34,279 Speaker 1: cool little town. Anyway, She writes in and says, I 649 00:37:34,360 --> 00:37:37,040 Speaker 1: really enjoyed your podcast on the relationship between science and 650 00:37:37,040 --> 00:37:39,239 Speaker 1: the Catholic Church. I've wondered since I was a little 651 00:37:39,280 --> 00:37:41,560 Speaker 1: kid what Catholics would do if aliens were discovered, so 652 00:37:41,560 --> 00:37:43,279 Speaker 1: I really got to kick out of the topic. I'man 653 00:37:43,360 --> 00:37:46,719 Speaker 1: about Catholic studying archaeology, so the conflict between the Church 654 00:37:46,760 --> 00:37:49,960 Speaker 1: and science is an important one to me, especially concerning evolution. 655 00:37:50,680 --> 00:37:53,480 Speaker 1: It's really encouraging to hear about people like Guy counsil 656 00:37:53,520 --> 00:37:57,799 Speaker 1: Mango who are passionate about both religion and science. And 657 00:37:57,840 --> 00:38:00,839 Speaker 1: what he said about fundamentalist was excellent and act. While 658 00:38:00,960 --> 00:38:02,640 Speaker 1: they have certainly been that way in the past, the 659 00:38:02,680 --> 00:38:04,880 Speaker 1: modern Catholic Church is not nearly so harsh about its 660 00:38:04,960 --> 00:38:06,960 Speaker 1: views as a lot of people seem to think. They 661 00:38:06,960 --> 00:38:09,120 Speaker 1: have been okay with and even encouraged the old stem 662 00:38:09,120 --> 00:38:11,600 Speaker 1: cell research for many years, and Pope on Paul's second 663 00:38:11,840 --> 00:38:15,920 Speaker 1: published an encyclical stating that much of evolution area theory 664 00:38:16,120 --> 00:38:18,479 Speaker 1: is not indirect contradiction with the views of the Church. 665 00:38:18,800 --> 00:38:20,480 Speaker 1: So I'm really glad to hear that the Church has 666 00:38:20,480 --> 00:38:22,759 Speaker 1: been making efforts to make their views better known. I 667 00:38:22,800 --> 00:38:24,960 Speaker 1: hope they continue with this because it would make me 668 00:38:25,040 --> 00:38:28,239 Speaker 1: feel much more confident in being a Catholic archaeologist. Keep 669 00:38:28,239 --> 00:38:30,440 Speaker 1: going with the great podcasts. I always enjoy them when 670 00:38:30,480 --> 00:38:32,200 Speaker 1: I'm taking a break from work or going to bed. 671 00:38:32,600 --> 00:38:34,919 Speaker 1: And I like how I get to learn something new 672 00:38:35,000 --> 00:38:39,040 Speaker 1: even when I'm relaxing.
