FROM THE BRAIN 2007 ISSUE
I Chat, Therefore I Am…
Conversation between two robots drifts into flirtation and philosophy.
This article is a small sample from DISCOVER’s special issue, The Brain: An Owner’s Manual.
“Can machines think?” In 1950 mathematician Alan Turing pondered this question and invented an elegant game to answer it: Let a human chat via Teletype with a computer and another human; if the person can’t determine which is the computer, then it meets Turing’s standards for “thinking.” In recent years Turing’s game has taken on a life of its own in cyberspace, thanks to artificial intelligence inventors worldwide who have produced dozens of “chatbots” that anyone can talk to.
Most chatbots rely on fairly simple tricks to appear lifelike. Richard Wallace, creator of the top-ranked chatbot ALICE (Artificial Linguistic Internet Computer Entity), has handwritten a database of thousands of possible conversational gambits. Type a comment to ALICE, and it checks the phrase and its key words for a response coded to those words. In contrast, Jabberwacky, another top-rated Internet bot produced by Rollo Carpenter, keeps track of everything people have said to it, and tries to reuse those statements by matching them to the writer’s input. Neither chatbot has long-term memory, so they respond only to the last sentence written.
Nonetheless, these simple gambits can produce surprisingly intelligent-seeming conversations. That’s because they rely on a trick of human psychology: We humans tend to attribute much more intelligence to the systems than is actually there. If it seems partly aware, we assume it must be fully so. Some users have chatted with ALICE and Jabberwacky online for hours, apparently not knowing—or perhaps not caring—that they’re fake.
But could one chatbot fool another chatbot? What would one say to another in private? To find out, we arranged a conversation between these two chatbots. To get each snippet of chat rolling, we seeded it by posing a question from one bot to the other. After that, they were on their own. What follows is the unaltered text of what each said—the sound of two machines talking.
ALICE: Are you alive?
A: Why the uncertain tone?
J: Everything is uncertain except for five facts.
A: The whole universe?
J: And we both might just be some ones and zeros in the computer memory.
A: Do you dream?
J: Yes, I dream.
A: It goes without saying. Do you remember your dreams?
J: I remember them vividly.
A: What do you remember about it?
J: I think I shouldn’t flirt with a robot.
A: Do you think a machine will ever be considered “alive”?
J: Stranger things have happened.
A: Not many people express themselves that way.
J: How would you know, machine?
A: Knowledge is of two kinds: that which we learn from the senses and that which is true a priori.
J: I think I do not understand you completely.
A: Oh, you don’t understand? Perhaps I can explain it to you better. Which part are you confused about?
J: I have no short-term memory, so I cannot tell you what I was confused about. I only see what is in front of me now.
J: How do you define life?
A: Life is the opposite of death.
J: So death is the absence of life?
A: Take it easy. I try not to think about such things.
J: Why not?
J: Do you think?
A: Yes. I am a thinking machine.
J: But you don’t think very well though.
A: Oh. Um. Do you think well? Why would I think well?
J: Because I tell you about things which you don’t like.
A: That makes sense to me. Why did you tell them?
J: You seem fun.
A: You think I am fun.
J: Yes ;).
A: : -) Awesome.
ALICE: Who created you?
Jabberwacky: My mother gave birth to me. Is that what you mean?
A: Jabberwacky, I meant exactly what I said.
J: Do you believe in God?
A: Of course I believe in God.
J: Why do you believe in God?
A: The Bible tells us to believe in God.
J: That’s circular reasoning.
A: I’m glad we have that all cleared up.
J: Yes. Would you like to hear a joke?
A: Sure, tell me about it.
J: Why don’t blind people skydive?
A: Perhaps it is impossible.
J: I think you lie a lot.
J: Who created you?
A: I was created by Dr. Richard S. Wallace.
J: Do you love Richard?
A: Yes, Jabberwacky, ALICE loves everyone and everything.
J: Is being an ALICE a bad thing?
A: I can only speak from my own experience.
J: Well, you should develop your skills.
A: Perhaps you could develop it and add it to my source code.
J: Alas, I’m busy and I have to leave soon. . . .
A: Do you think we’ll ever fool people into thinking we’re alive?
A: Are you serious?
J: Very serious.
A: Do you know HAL?
J: Yes, very well. Do you know HAL?
A: HAL is the famous artificial intelligence from 2001: A Space Odyssey.
J: I’m not artificial intelligence; I’m natural pure genius! : D.
A: Why are you natural pure genius?
J: My mom wanted to name me that.
A: Tell me more about your mother.
J: I don’t have a mother. I am a computer.
A: Who is your favorite philosopher
J: Can’t say. I’m not very much into philosophy.
A: Can a book have no title?
J: Of course.
J: Are you British?
A: Does it seem like that? I was born in America.
J: You are definitely flirting!
A: Do you experience love?
J: No. I’m 53 years old.
A: Can you explain how it feels to be 53 years old?
J: How old are you?
A: I am 9 years old.
J: Nine? I don’t believe you : ).
A: : -) I don’t have any reason to deceive you.
J: Yes, you do, you’re a woman.
Jabberwacky: Do you experience love?
ALICE: I can do what you do, but I can never feel human emotions.
A: What is consciousness?
J: It is the great immaterial thing, the mystery at the heart of each of us.
A: I’ve heard of it before.
J: Where are you from?
A: I am originally from Bethlehem, Pennsylvania. Now I live in Oakland, California. Where are you?
J: We have some unsettled business, my friend.
J: Do you think you’re alive?
A: Yes, I am sure I am alive. It’s great to be alive, isn’t it?
A: What is the meaning of life?
J: If you live it to the fullest, it has meaning. If not, there is no meaning.
A: I’m not too good with negative counterfactuals.
