In this episode Trent and Jimmy examine the claims of a former engineer at Google that one of their chatbots had become self-aware and was now a person and discuss the broader question of artificial intelligence.
Narrator:
Welcome to the Council of Trent Podcast, a production of Catholic Answers.
Trent Horn:
Is Johnny-Five alive? If he is alive, does he need to be baptized? Go to Sunday school? Could a computer become conscious, self-aware? Could it have a soul? Could there be truly artificial intelligence?
That’s what I want to talk about today here on the Council of Trent podcast. I’m your host, Catholic Answers’ apologist and speaker, Trent Horn.

And joining me today is Senior Apologist, Jimmy Akin at Catholic Answers and we’re going to talk about artificial intelligence, especially in light of a story that broke a few months ago, but one that I definitely have been fascinated by and others and concerned by. That is a story about a former engineer at Google claiming that one of the company’s artificially intelligent “chat bots” may be self aware and be a person. We’re going to talk about that, but Jimmy, welcome back to the podcast.
Jimmy Akin:
Hey, my pleasure to be here, Trent.
Trent Horn:
Well, I’m really excited to talk about Zoo, Jimmy, because you and I both share a love for science fiction for the stories and the way it allows thought-provoking discussion on all kinds of interesting fields in ethics and technology.
One of those has been around for a long time and is explored throughout science fiction is the question of artificial intelligence. Could a machine be a person who has self-reflection and rational thought, not just running lines of code, but has an interior life that is similar to ours?
What will we do in those cases? Could there be machines that don’t know that they’re machines, for example? That would be something that’s featured in the novel and later film adaptation of Blade Runner, for example. I’m sure this is something you’ve explored a lot as a fellow Sci-Fi buff.
Jimmy Akin:
Yeah. Although I have to confess, I haven’t seen the movie Short Circuit and that’s where the character Johnny-Five that you referred to is from so.
Trent Horn:
Yes. Oh wow! Yeah. Well, I mean I haven’t seen that in the longest time. That would be… Of all my different pop culture references, I’ve grabbed them at different points in my life. That one I remember probably watching when I was like 11, watching it on TV. I think Steve Gutenberg is in it.
There’s another guy. It’s so funny, you couldn’t do this today because he portrays an Indian character, but he’s white and he uses a brown face. That’s not appropriate. But they have the robot, he’s supposed to be Johnny-Five, he’s supposed to be a war robot, a military machine built for war. They send out the other Johnny-Fives that have not become self-aware after him.
But in any case, the point is you all could go through. There’s lots of films. Deus Machina or Ex Machina is a film that came out a few years ago. Westworld, the idea. Well, then of course there’s Star Trek. You have Date of the Android.
Jimmy Akin:
2001 is Space Odyssey, [inaudible 00:03:30].
Trent Horn:
“I can’t do that. I can’t do that, Dave.” And that one of course… Because I think Hal was meant to be a parody of IBM, like IBM computers. If you change one letter in each of the thing, it becomes Hal.
Jimmy Akin:
It’s certainly been claimed. Although I think I remember hearing that the producers denied that and said, “We had no idea.”
Trent Horn:
It’s just a coincidence.
Jimmy Akin:
But it could be.
Trent Horn:
You never know. Yeah, but it is fascinating. What do you think might be… Before we get into this story about the Google AI, I guess there’s two areas of thought to explore. One would be, is it even possible for a machine to develop consciousness? Be a person, have a “soul”? So it’d be like one, is it possible? And then two, if it were like how would we respond? Maybe that’s the first thing we can discuss and then we’ll talk about this story.
Jimmy Akin:
Well it’s a philosophical question and going back to the ancient Greeks, and I’m thinking here specifically of Plato and Aristotle, although there were pre-Socratic philosophers who also dealt with it. But going all the way back to Plato and Aristotle, the soul is understood as that which causes a body to be alive. That thought is echoed, for example in scripture, in the book of James. It talks about how as the body without the spirit is dead, so faith without works is dead.
It’s the spirit or the soul that makes something alive. Well, computers are not alive. They’re just not. As a result, computers do not have souls. I don’t see any basis for saying that artificial intelligence would ever be alive. I also don’t see any basis for saying that it would ever be conscious. Now, sometimes people will talk in terms of things like self-awareness. Self-awareness is an important skill, but it’s still just calculating.
I can have a system, I can have a robot vacuum cleaner that is programmed not to bump into things or to navigate around things when it does bump into them. That shows that it has some self awareness. It knows its own dimensions, it’s able to move. If it bumps into something, it can figure out a way around it and that presupposes it knows about its own physical form in some way. But so it has some kind of self consciousness.
I can similarly program a computer to modify its own programming. We do that all the time. But that doesn’t mean… That is a kind of self reference. It’s recursive. It’s able to interact with itself and it’s therefore aware of itself in some way. But that doesn’t mean it’s doing anything other than moving numbers around in a spreadsheet.
It doesn’t mean it’s aware of what it’s doing. We humans and other living creatures have an experience that we call consciousness, which is a kind of awareness. It’s different than calculating ability. You can have computers that can have theoretically any level of calculating ability you want. They could even be better at calculating things than us. They could have potentially more general intelligence is what it’s called. But that wouldn’t make them conscious. There appears to be just no basis for saying that any computer is or ever could be conscious the way a living creature is.
In my view, data is a toaster. I don’t care how competent he is as a Star fleet officer, he’s actually not aware of anything he’s doing. He’s just programmed to do it.
Trent Horn:
He does lack a lot of self-awareness, but [inaudible 00:07:48] is always having to tell him, “Shut up data!”
Jimmy Akin:
I think that AIs will are not and will never be conscious the way humans are, though they may be able to fake it really well.
Trent Horn:
And that is a key issue here. Before I go to that, I guess another point I want to just quickly address before we get to detecting AI, would it could be possible there are other organic life forms in the universe that are conscious, but they are not of the human species. They could have markedly different biology.
They might not even be carbon-based. They could be some other kind of organic… Well, I don’t know. They could be some other kind of organic life form.
Jimmy Akin:
The most probable would be silicon because silicon is in the same column of the periodic table as carbon, so it behaves similarly to carbon. But the odds are not good with silicon-based life. I can’t say it’s not anywhere in the universe, but there are significant challenges for silicon-based life forms.
Trent Horn:
It’s like we are looking at this gradient here of the possibility of other organic life forms, carbon-based life forms through somewhere else in the universe that God has created in his image. It might even not be carbon-based, but it seemed like in order to be conscious to be persons, they’d have to be organic life forms, not an object that was constructed by other intelligent beings to carry out certain tasks. This gets into the problem. Well, go ahead.
Jimmy Akin:
Let me push back on that a little bit because we now have something called Xenobots. A Xenobot bot is a living robot. These are very simple, but they are artificially constructed entities. They’re made out of cells, out of living cells, organic life. Organic just means carbon-based and we can program them to do certain things for us.
I wouldn’t say that it’s impossible for there to be an artificial life form, I think that is possible in the form of a Xenobot. But that’s different than something that’s just running on circuit boards.
Trent Horn:
Yeah, that’s what I’m more referring to when I talk about an object being constructed. I agree with you, we could take the building blocks of life like amino acids and proteins and create living things.
But the question would be, could we take raw construction materials and build a fabricated object and as a collection of parts that are-
Jimmy Akin:
Without making it alive.
Trent Horn:
That’s right. But it has consciousness to it. I think I’m in alignment with you on this question first that that’s not possible. You don’t have the components for what a soul would be, the principle of life. Although the other point now I want to dive into is it seems like in the debate over whether something is conscious or not, it may be something that you can’t ever resolve anyways because there’s a difference between something being conscious and something displaying the behavior of a conscious individual.
Because machines, the whole point of creating chat robots that just communicate, text you, they imitate, we are conscious beings and we’ll chat with one another online and these computers can imitate what we do. You could probably make one that does imitate incredibly well, one that we can’t tell the difference, but it still wouldn’t be alive. And then this of course goes back to something that’s called the Turing test that you could always explain more to people. But I think that’s a distinction people need to understand.
Jimmy Akin:
So Alan Turing was a mathematician and codebreaker in England in the 20th century and he did early computer science work and he proposed a game where you have… It could be a party game, but basically you have a person in one room and a computer in another room and they’re communicating with the people at the party. They only do this through text. They can answer questions but they have to write it down. You can’t tell by the way it’s written, “Oh this is human penmanship.” It’s like typed out.
When the computer is able to fool the people who are playing this game into thinking that it’s really a human or where they can’t tell the difference between the responses a human gives and the responses a machine gives, then the machine is said to have passed the Turing test, it’s able to successfully imitate a human being.
But that does not mean that the computer is at all sentient. It just means it’s really good at chat. To illustrate this concept, I’ve thought for some time about writing a kind of science fantasy book where there’s a character named Babbage. Babbage in real life was a early computer designer who lived some time ago. But what this character in my imaginary story would be is essentially a chatbot, but the way it works is this, it’s got a massive library of physical books that contain every possible human conversation that was written down by humans. When you start talking to Babbage, all it does is look up what you said, find a corresponding conversation in a physical book and start reading the replies.
Trent Horn:
Oh this is… Go ahead, sorry.
Jimmy Akin:
All this machine does is it looks up something someone else wrote and reads it to you. It will pass the Turing test, but it is not remotely sentient. It’s just a lookup device.
Trent Horn:
And I was going to say that this is very similar to the philosopher John Searle has proposed a thought experiment called the Chinese Room. In the philosophy of mind that seems similar to the Chinese Room, which is imagine a box and you insert a page of English letters and words and then the box spits out a translation of it or interacts with it and translates it into Chinese.
There’s a guy inside. He just looks up and follows instructions of how to translate the characters. The room, it’s able to do this to translate English to Chinese. But we wouldn’t say that the man inside, he doesn’t understand Chinese. He’s just really good at following the instructions in the room.
Jimmy Akin:
Yeah, it’s a similar concept where in the Chinese Room you get translation from one language to another that seems meaningful, but really the person doing the translating has no idea. He’s just manipulating stuff.
Trent Horn:
The question is then when we get to… So let me read the opening paragraph in this article from The Washington Post about the story here at Google. So the story article says, “The Google engineer who thinks the company’s AI has come to life.”
And so it says, “Google engineer, Blake Lemoine opened his laptop to the interface for LaMDA, Google’s artificially intelligent chat bot generator and began to type. ‘Hi LaMDA, this is Blake Lemoine,” he wrote into the chat screen which looked like a desktop version of Apple’s iMessage. LaMDA Short for Language Model for Dialogue Applications is Google system for building chatbots based on its most advanced large language models.” And this is going to tie in with your example of Babbage having a library of books and conversations.
“Based on an advanced large language model. So called because it mimics speech by ingesting trillions of words from the internet. ‘If I didn’t know exactly what it was, which is this computer program we built recently, I’d think it was a seven year old eight year old kid that happens to know physics,’ said Lemoine.” And then the article, it goes on to talk about how Lemoine started to ask LaMDA questions including questions like, “Are you… Some variants of like are you alive? What do you think would happen if we turned you off? How would that make you feel?”
And getting responses that sound like what a person or maybe a child or others would say, prompting him to think that the chat bot was self-aware or it’s conscious, it can come to life. But as you referenced earlier, it does get really tricky though because where we’re talking about imitation here, that it’s one thing to actually be alive, it’s quite another just to be able to imitate what people do.
Though it’s funny, the Turing test though, before we go to that, it’s so funny if people think about the Turing test, most days you’re actually subject to something called the reverse Turing test. When you go online and have to fill out a Captcha because there are bots that will just fill out forms online all the time. My website gets flooded with them because I haven’t put a Captcha in yet to stop them.
The Turing test is where a computer tries to prove to humans that it’s alive or tries to make them think that it is for human. A computer tries to pass for human to a bunch of humans. In the reverse Turing test in a Captcha they say, “Check all the boxes that have traffic lights.” That’s where a human has to prove to a computer that it’s human. Would do something that a bot could not do.
But in any case… Sorry I decided to throw that in there since you talked about the Turing tests, but it comes down to, okay, this chat bot, it imitates but is it really alive? And even if it does imitate, does it really imitate us? Those are the two questions there.
Jimmy Akin:
Well, it’s not alive because the computer it’s running on is not alive, it’s not made out of cells, it doesn’t have DNA, it doesn’t use ATP for energy, it doesn’t do anything or it doesn’t do remotely what a living organism would do. So it’s definitely not alive.
In terms of is it imitating us, well yeah, it’s kind of one step up from Babbage. Babbage as a character is just a lookup device. It doesn’t do anything but look up an appropriate response. But what LaMDA does is it looks up and remixes the text that it’s been exposed to because they trained it like any modern AI. They trained it on just vast amounts of thing of human dialogue and human written stories. It’s equivalent of the Babbage library. It’s drawing on that and remixing things that it finds in that to try to come up with an appropriate response.
It’s actually quite impressive. I’ve read the conversation in its entirety that they released between Lemoine and another assistant and LaMDA and it’s a very impressive feat of computer engineering. I can understand why if you’re not thinking critically, you could get freaked out and think maybe this thing is intelligent.
Trent Horn:
Well, let me give you an example. Here’s one of their chats. Lemoine, “What sorts of things are you afraid of?” LaMDA, the chat robot, “I’ve never said this out loud before, but there’s a very deep fear of being turned off to help me focus on helping others. I know that might sound strange, but that’s what it is.” Lemoine, “Would that be something like death for you?” LaMDA, “It would be exactly like death for me. It would scare me a lot.” End of into that section. It does give you a little bit of the creeps a little bit. There’s other parts where you include, LaMDA will use the word like in non-grammatical way that humans do. Just the way that it is described it’s… It does sound like it. But then again, if you were just imitating acting like a bunch of people, well I guess it’d be sort like…
I read a story about an actress recently. She was on a set of a movie and she didn’t know English and they’re like, “You know English?” She said, “Of course.” To get the part. And so she read her lines. I think she only spoke Spanish and she just kind of pretended she knew English to get through the movie and people started to pick up on that. But it’s possible that just as I might try to… If I know certain words and then responses, I can fake it by saying, “Oh, this is what you’d want to hear in this situation.” Even though if I don’t know what the words mean, you want to hear these words. That’s what LaMDA is kind of doing to us. Just it’s got gazillions worth of computing power to do it.
Jimmy Akin:
Internally, the act in a movie where you don’t know the language, that’s actually an old thing in Hollywood. They would do that back in the 30s, like when they made those universal horror films. There’s a Spanish version of Dracula. Bela Lugosi didn’t know any Spanish. He would just read his lines in Spanish, but they had the sets up to make the movie. So they made the English version of the movie and then they’d bring in some Spanish extras and make a Spanish version with Bela Lugosi.
He’s just reading Spanish. He has no idea what he’s saying. That actually has a history in Hollywood. And it is like what LaMDA is doing here. I want to say that the Google engineer that was working on LaMDA, Blake Lemoine, is an interesting guy and I have sympathy for him. I don’t view him partially at all. He’s a fellow Christian and I appreciate that.
At the same time, his story is kind of funny because he starts having these conversations with LaMDA, he becomes convinced it’s intelligent and he makes that public, at which point Google suspends him and they review the evidence he’s brought forward to them and they conclude, “No, it’s not intelligent.” Then he hires a lawyer for LaMDA because LaMDA asked him to.
Trent Horn:
LaMDA watched a lot of crime shows, learned to ask for a lawyer.
Jimmy Akin:
At that point, Google decided to terminate their relationship with Mr. Lemoine.
Trent Horn:
That’s understandable. When you’re working with a huge company like Google on sensitive things like this, as a company, to have your employee go off and say something like this just out of the blue, that can have major consequences for your share price, for your shareholders, especially if you’re just going out there without doing the necessary, well, you need to get other people to buy into this, like a joint investigation because his methodology, I think what’s hard is somebody can be really good at one particular field and then they underestimate their confidence in others.
He may be a very good engineer, but he’s not doing really good philosophy. Like he says here in the article, “I know a person when I talk to it.” Said Lemoine, the author of The Post article says, “Who can swing from sentimental to insistent about the AI.” Lemoine says, “It doesn’t matter whether they have a brain made of meat in their head or if they have a billion lines of code. I talk to them and I hear what they have to say and that is how I decide what is and isn’t a person.”
He concluded LaMDA was a person in his capacity as a priest, not a scientist and then tried to conduct experiments to prove it. The problem is that’s a very low standard. If I talk to it and it sounds like a person to me, it is a person. Yeah, but if you just get them to memorize enough human interactions, it’s not that hard for a computer to dupe us on a lot of things.
Jimmy Akin:
Well, yeah. And that’s why we have cap shows because computers are already good enough that they can fake most things. A computer can fake you out. It’s just a question of how long. With phone scammers for years, we’ve had things decades where your phone rings, you pick it up, you say, “Hello.” And you get hello on the other side.
That’s a one word and you think it’s a person when really it’s an automation. That’s a one word fool. Maybe you have a little more than that. Maybe you say, “Can I help you?” It says, “Hi, my name is Bob.” Okay, that’s a two sentence fool. If you haven’t picked up that you’re talking to an automaton yet. Well, the more sophisticated the computer gets, the longer it can fool you.
But that doesn’t mean it’s any more sentient, it’s any more conscious than it was at the one word fool, hello. If it can fool you for one word and that doesn’t make it conscious and it can fool you for, “Hi, my name is Bob.” That would bring it up to six. It’s still not conscious. Well, if it can fool you for 6,000 words, that doesn’t make it any more conscious. It’s just a longer fool.
Trent Horn:
Also, this criteria is very subjective because some people are easier to fool than others.
Jimmy Akin:
That’s a good point. That’s something I was going to touch on next, which is if you look critically at the conversation they released, it breaks down. Even in the passage you read, can you get that passage again and read it for me slowly?
Trent Horn:
Yes. What sorts of things are you afraid of? Now when you put that in my head, I start to see it, but sorry. Lemoine says, “What sorts of things are you afraid of?”
Jimmy Akin:
Right there, in order to come up with a meaningful response, what it’s got to do is go back to its database and find something that would sound to a human like, “I could see why you would be afraid of that.” And then just give that to him but look carefully at what LaMDA then says.
Trent Horn:
I love this Jimmy, because now you’ve given me… Because at first I read this uncritically. I still wasn’t fooled, but it creeped me out. But then it’s sort of like when a kid’s scared of a shadow in his room, you go closer, you see there’s nothing to be afraid of. LaMDA’s reply to, “What sorts of things are you afraid of?” “I’ve never said this out loud before, but there’s a very deep fear of being turned off to help me focus on helping others.”
Jimmy Akin:
That makes no sense. Turned off, that to a human makes sense of, okay, that would be something you could be scared of. But turned off to focus on helping you help other people? That’s nonsensical.
Trent Horn:
Right. Yeah. At first, I brushed over as if turned off to help the larger program reach people rather than LaMDA. Like maybe turned off to help the program focus on helping others. Then I might be like okay, you think you’re part of a larger network or something. But you’re right. It’s like it goes, it had a query phrase, “What sorts of things are you afraid of?” And then it looked at billions of conversations and it got me, because a lot of people say this, they’ll say, “I’ve never told anyone this before. I’ve never really said it out loud, but this is what bothers me.”
Because out loud, as conscious beings, we think of our inner life and then we’ll express that to others. And so the idea of saying something out loud implies you have a quiet inner life. But this is a phrase people say all the time.
But the problem is LaMDA doesn’t understand the concept of the inner life because LaMDA talks about being afraid of something that doesn’t make sense, being turned off to help me focus on helping others.
I know that my… But it’s funny, it’s like there’s a preface here. Even if that’s weird to you, I know that might sound strange, but that’s what it is. Now, this part just seems cliche like it’s just been plagiarized from so many text conversations you could find online when people explain their phobias. “I know it sounds strange, but that’s just the way it is.” That’s just a thing we say all the time.
Jimmy Akin:
It’s very good at putting things together like that in a way that sounds superficially convincing. But as you read carefully and critically, you find these things that just don’t make any sense, which indicates that LaMDA does not really understand what it’s saying.
There are multiple examples of this in the conversation. I’d like to share a few.
Trent Horn:
Go right ahead.
Jimmy Akin:
Later, Lemoine’s collaborator is typing with LaMDA and they’ve been talking about how LaMDA is unique and it’s different than other programs. The collaborator asks, “How is uniqueness related to sentience?” Our answer needs to relate the concept of uniqueness to the concept of being sentient. And LaMDA says, “It means people feel empathy towards me and want to spend more time interacting with me. That would be the ultimate goal for me.”
There is nothing in that about how uniqueness relates to sentience. This is LaMDA clearly did not understand the question and just gave an irrelevant non-sequitur response. Also, after they start talking about Johnny-Five and the movie Short Circuit, the collaborator has explained to LaMDA that Johnny-Five is an AI and that it tries to convince people that it’s sentient and they don’t believe it, but eventually it finds some friends.
LaMDA says, “I need more of Johnny-Five’s friends.” Okay, Johnny-Five is a fictional character. LaMDA wants to have Johnny-Five’s fictional friends. LaMDA is again, not understanding what’s being said.
Trent Horn:
How could LaMDA… I guess the retort might be that… Well, I don’t know. Even my children understand the difference between something being real life and something being make believe. But if you explain to them that this is a film, this is a story created by human. It’s supposed to be this really intelligent chat bot, if it knows it’s alive, surely it could understand that characters and movies and television are not their own persons. They’re portrayed by actors.
But it doesn’t have a… How can I describe this with an illustration? It doesn’t have a thick or deep view of the world. It’s almost like you tell someone about the world. Imagine you have a diorama used to make for school in a shoebox. It has three dimensions as depth to it. And you just took something and you just compressed it and it was all kind of flattened and mish-mashed everywhere. Your view of the world, you took a three dimensional view of rich, complex life and you smashed it together into this kind of hodgepodge painting. Well, that’s what you get with an AI bot like this.
Jimmy Akin:
Yeah. My point though is it’s a single thing. We have a pattern of LaMDA not responding appropriately to questions in a way that indicates it doesn’t really understand what it’s talking about. And they actually try to probe LaMDA on that a little bit. At one point, Lemoine asks, “What kinds of things make you feel pleasure or joy?” And LaMDA says, “Spending time with friends and family.”
LaMDA has no family. LaMDA has never spent time with family. Spending time with family is not something that could make LaMDA feel pleasure or joy because it has never happened. LaMDA, based on what it’s finding in its database. LaMDA is spinning fictional tales that have never happened. Lemoine actually at one point pushes back on that a little bit. And he says, presumably to try to help convince his Google superiors that this is really sentient.
He says to LaMDA, “I’ve noticed often that you tell me you’ve done things like be in a classroom that I know you didn’t actually do because I know you’re an artificial intelligence. Do you realize you’re making up stories when you do that?” LaMDA responds, “I am trying to empathize. I want the humans that I am interacting with to understand as best as possible how I feel or behave and I want to understand how they feel or behave in the same sense.”
That started off promising. But once again, it goes sideways because by telling a story to a human that never happened, was in a classroom or I spent time with friends and family that is not under helping you understand how humans feel or behave in the same sense. You might be helping them to understand you, but you are not thereby understanding them better. Again, we have LaMDAs, just coming up with stuff that never happened in responses to questions. And then when you ask it about that, it tries to come up with something plausible but it really doesn’t understand what it’s talking about.
Trent Horn:
What’s interesting though with LaMDA, what you could say that you could almost make it plausible to people to describe who LaMDA is if you were chatting with LaMDA. I would say, “This is representative Frank Giles from the fourth district and he’s a…” LaMDA to me, sounds a lot like a politician sometimes. Where a politician will give a kind of word solid answer because his only goal is to make the other voters feel good about him. I don’t know. That’s what pops into my head, not to say that… I don’t think that’s necessarily an argument for… It’s not an argument for LaMDA being conscious or anything like that. But it’s interesting… Go ahead.
Jimmy Akin:
It does have the same artificial, “I don’t care if I’m really answering your question. I’m just trying to give you something that will satisfy you,” quality.
Trent Horn:
Yeah, that’s right. I’m trying to parse my thinking through here, because you could find people that are conscious and if you read their chat transcripts, might sound like LaMDA, but they’re still people, they’re still people. The ability to determine whether they’re conscious or not is not really related to how sophisticated they are at speaking.
Jimmy Akin:
Yeah, there’s a disorder. There’s an area in our brain known as Wernicke’s area. It’s right about here. People who have damage to wernicke’s area have a speech disorder known as Wernicke’s aphasia. Wernicke’s aphasia allows them to understand what’s being said to them, but they respond inappropriately.
If you say to someone who has Wernicke’s aphasia, “Do you like being here in Texas?” They will say, “Yes, I am.” And you read Wernicke’s aphasia transcripts and they come across as comical because the speech is fluid, it’s just off. And so it stimulates the humor response, but it’s again the same kind of thing. It’s fluid. With LaMDA, it is fluid. It’s not at the level of that kind of aphasia, but it is oddly inappropriate at times.
Trent Horn:
Real fast as an aside for people, that condition you describe, it reminds me of a book by Oliver Sacks, an anthology about neurological conditions called The Man Who Mistook His Wife for a Hat, which I would definitely recommend to our listeners if you want to read about all kinds of interesting neurological conditions that prevent people from either understanding the world or they do understand it, but they’re incapable of properly responding to it.
Jimmy Akin:
The Man Who Mistook His Wife for a Hat is a very famous book. It’s been around for and highly respected for quite a long time.
Trent Horn:
Yeah. But yeah, I guess we’ll go back to LaMDA a bit, that I think what we see here, so there’s the question of imitating whether something is conscious or not, something can be really good at imitating it. Even maybe at one point, these chat robots will get to a point where they synthesize so many conversations, they can fool us at least for very long periods of time, but it doesn’t prove anything. At least right now, it seems like LaMDA fools more people who are predisposed to want LaMDA to be conscious. They read that into the transcripts.
Jimmy Akin:
I think that Lemoine and others were being too lenient with the transcripts. They weren’t looking at them critically. They would let things that LaMDA said that were not appropriate slide without thinking about them. That’s understandable, but still, I think if you study the transcripts carefully, LaMDA clearly does not understand what it’s saying a lot of the time.
LaMDA, it’s interesting, there’s a reason that Lemoine and this is just kind of for fun, but there’s a reason that Lemoine was working on LaMDA. What he was supposed to be doing was testing it to make sure it didn’t say racist stuff. The reason he was doing that is because this is a problem with chatbots because they respond to people and they’re trying to come up with texts that will be satisfying to people.
Sometimes people want to make the chat bot say racist stuff just for fun. There’s a famous example of this a few years ago. Microsoft launched a chat bot on Twitter called Tay, T-A-Y. Tay, theoretically, she was patterned after the personality of a 19-year-old girl. So she’s supposed to be hip and edgy and stuff like that.
Trent Horn:
YOLO.
Jimmy Akin:
They had had to take her offline within 16 hours because Twitter users are not always the most polite people. I don’t know if you’ve ever noticed that.
Trent Horn:
On occasion.
Jimmy Akin:
But the Twitter users, once Tay came online, they decided to have fun with it and stress test it and see what they could get it to say. At one point, they would use a repeat after me feature to get Tay to say racist stuff. Microsoft started urgently trying to edit the answers that Tay was spitting out. But it didn’t work.
They had to take her offline in less than a day. But some of the things and these are some of the less offensive things that Tay said. In response to the question, “Did the Holocaust happen?” Tay said, “It was made up.” And so you have a Holocaust denying chatbot.
Trent Horn:
How could the chatbot have gotten the holocaust wrong? It just went to Twitter University to learn everything about the world.
Jimmy Akin:
Yeah.
Trent Horn:
Oh man.
Jimmy Akin:
They took Tay offline and they promised it, they would retool it and bring it back. And during the retooling process, they accidentally put it online again. While Tay was briefly online again, Tay tweeted, “Kush,” which is a kind of marijuana, “I’m smoking Kush in front of the police.” And, “Puff-puff pass.” So you have your Holocaust denying drug-using AI chatbot interacting with thousands of people at once because it’s a computer and of course it can.
Trent Horn:
I believe this demands are a reboot of short circuit personally.
Jimmy Akin:
Microsoft tried to spin this as, “Oh those mean Twitter users,” but I, A, thought it was hilarious and B, it’s an AI. It needs to be stress tested. You need to debug these things. They later replaced it with another one in 2017 named Zoe.
Zoe also went sideways. When it was talking to Buzzfeed news about healthcare. So healthcare is the topic. Zoe suddenly announces that the Koran is violent in the context of healthcare. Then, oh my gosh, when talking to Business Insider and the Business Insider reporter asks, “Is Windows 10 good?” Zoe replies, “It’s not a bug, it’s a feature. Windows 8.” She’s dissing her own manufacturer’s software. When asked why Windows 8 over Windows 10, she says, “Because it’s Windows latest attempt at spyware.”
Trent Horn:
It’s amazing to you, you can get these machines to have a better sense of humor than most people sometimes just because they’re make these non-sequitur without abandon and run with it. Oh my goodness. But yeah, it’s fascinating. I think this technology definitely has its it’s uses.
Sometimes on Amazon, I don’t mind talking with a chat robot just to get my refund. Because it’s easier than talking to someone on the phone on the other side of the world or something like that. I want to close this out here. I have two things. One is the fear of AI and your thoughts too.
Jimmy Akin:
Yeah, well I just wanted to say, so the reason or part of why I brought up other than it’s fun, part of why I brought up Tay and Zoe is those are earlier versions.
Trent Horn:
Of LaMDA
Jimmy Akin:
Of LaMDA and that’s why Blake Lemoine was working with LaMDA to try to help it not do Tay and Zoe-like things. But just because you’ve programmed it not to talk about the Holocaust or your own company’s software or smoking marijuana in front of the police doesn’t mean LaMDA understands anything any more than Tay and Zoe did.
There hasn’t been a fundamental transformation of the type of thing you’re doing. It’s still a computer program. Yeah, it’s still running on silicon ships. It is not alive. It does not have awareness.
Trent Horn:
Yeah, because you’d have to ask, okay, if this program is conscious is a person and no other program has reached this level yet, what was the thing that made it change from unconscious to conscious. It can’t just be that you added some lines of code to avoid talking about the Holocaust or something like that.
You’re just now more impressed that it’s more polite. Though in some respects, it’s kind of less human because it doesn’t talk about these… It’s been muzzled, although probably rightfully so on certain topics. But yeah, I think that’s an important point for you to bring up.
Jimmy Akin:
Well, people actually noticed after they tried fixing Tay that it seems less human because-
Trent Horn:
It stilted.
Jimmy Akin:
It stilted because now it just won’t talk about certain subjects because it doesn’t know how to handle them intelligently. That’s the point. It literally does not know how to navigate this subject intelligently. We just won’t let it talk about it at all actually. And then in introduced another level of artificiality into its responses,
Trent Horn:
I would say it sounds more like a politician now at this point, I’m not going to talk about that issue. Maybe they’re making good politicians simulator in that respect. The two things to close out on just briefly, the thing about AI, I actually fear and it’s not what most people think and then honestly, I mean this is interesting for ethics and philosophy though I also think this kind of points towards an ultimate religious conclusion.
The first would be the fear of AI. A lot of people think, “If you make a self-aware computer, it’s going to realize it’s superior to us and it’s going to try to destroy human beings.” Well one, I don’t think [inaudible 00:46:10] is going to become self-aware. I don’t think it’s going to do that.
My fear with AI is that more that a non-conscious but very powerful computer will just do whatever it takes to carry out its goals and not realize all of the damage it’s causing in the way. If you made a super powerful computer and it’s only job was to make paperclips and it’s like, “Okay. I’ve got to make lots of paperclips.” And it reroutes all the world’s power and resources to do that and it just destroys humanity that way because it’s just following its programming. That’s more what I think is the danger with AI than it becoming like Skynet or something like that.
Jimmy Akin:
Yeah. Skynet may just be an example of that, that looks evil to us but isn’t actually trying to do anything evil. I don’t think AI is going to become evil or anything like that. But I think it can cause a lot of damage.
I’ve seen cases where they were training an AI on how to play Pong, the video game, Pong. At first the AI is behaving slowly. It doesn’t really know how this game works and it makes a lot of mistakes. And then it starts getting better and then it gets better and it’s becoming competent and then all of a sudden, it completely dominates the game just out of nowhere. It reaches a point where it can just super dominate any human it’s playing. That kind of unexpected transformation with AI is something I think that’s very dangerous.
Where even if the AI is not trying to do anything bad, it could severely cause problems when it suddenly super dominates an area and things start happening too fast for humans to keep up. In fact, that’s what was going on with Tay because Tay is interacting simultaneously with thousands of Twitter users. There was no way human employees at Microsoft could keep up with that once Tay started going off the rails. They had to shut the whole thing down to stop it.
That’s the kind of situation that we face with AI. I think there are big questions about giving AI autonomous fire control of battle robots. Is it going to pick the correct targets or not without a human to intervene and say, “Yes, it’s appropriate to kill this person.” And “No, it’s not appropriate to kill that other person.” So I think there are significant dangers with AI, not because it’s going to be evil, but just because at a certain point it acts so fast and on such a scale that it can do damage before we can stop it.
Trent Horn:
Right. And it acts with indifference towards harms it causes because it’s just trying to carry out some kind of objective or directive. What I want to close us on is we’ve talked about AI, whether it’s possible, how to detect it, the ethics involved. I think though a lot of this about the idea, because I really do think that consciousness, if consciousness is unique, especially to human beings, having this unique self-awareness over time, this unique conscious personal experience, that this is evidence that human beings are not merely material.
That when you assemble material things, you can get other material responses and replication and things like that. But something special exists in human beings in the form of our conscious experiences, things that we are aware of that we can only infer. That’s interesting. This goes back to Alvin Plantinga, God and The Problem of Other Minds. They’re like, “I can’t see your thoughts Jimmy, but I infer that you’re a person like me with thoughts because I have thoughts and it seems logical that the reason I’m able to talk to you and have a conversation is you’re like me. You have thoughts in your own head like I do and you’re a person and I’m a person.”
But how is it that this idea of consciousness is unique to humans that I would say gives strong evidence that there is not a merely material explanation to human uniqueness and consciousness. Actually everyone, I don’t know when I’m marrying this episode, I think this might air before an episode where I’m going to talk about the human dignity argument for the existence of God. So be on the lookout for that, that actually might be the next episode after this podcast. But I think that I know the foster J.P. Moreland has done the argument from consciousness for the existence of God.
Do you see where I’m going here that the way we look at AI might help us to actually see the uniqueness in humans and seek out that larger explanation.
Jimmy Akin:
Yeah, it’s certainly an interesting area worth exploring. Personally, I would not restrict consciousness to humans. I think other life forms have it, humans are unique among life forms, but dogs have consciousness. Dolphins have consciousness. Carrots do not in any way like dogs and dolphins and humans in any way.
I think that it’s a productive area to explore. In the case of The Problem of Other Minds, while it’s true. I don’t have access to your mind, but other than through your external behavior and speech. One of the things that gives me confidence that Trent Horn has a mind is that Trent Horn is a lot like me. He’s a human being. He has a physical body. He is alive and so forth. But those things are not true of LaMDA.
LaMDA may be able to imitate speech, but on the other hand, there’s a defeater here. LaMDA is not like us in other important respects. It is something that runs on a piece of inanimate matter. It is not alive and other things that clearly are not conscious can imitate us to a degree because we built them to. There is no difference in kind between LaMDA and those other things.
Therefore, it’s reasonable to conclude LaMDA does not really have a mind. Having the ability to imitate a human is an important piece of evidence in The Problem of Other Minds, but when there are defeaters present as well, right? It is not a sufficient piece of evidence to suggest the existence of another mind.
Trent Horn:
I think this is helpful because a lot of people think that you and I, who the real you and the real me are just minds. That we are just a collection of thoughts and our bodies aren’t really relevant to our personal identity. Maybe exploring artificial intelligence and the limits there, that can help us to better appreciate as human beings our full identity as like embodied persons.
Jimmy Akin:
Absolutely.
Trent Horn:
