Computer programs can also interact among themselves, of course, even though they need some human help. Here is a sample of an exchange between the computerized therapist, ELIZA, and the artificial paranoid, PARRY: parry: People get on my nerves sometimes. eliza: I am not sure I understand you fully. parry: You should pay more attention. eliza: Suppose you should pay more attention? parry: You’re entitled to your opinion. eliza: What makes you think I’m entitled to my opinion? parry: It bothers me just to be around people. eliza: Please go on. [Parry continues with some paranoid ramblings about horseracing, bookies, and the Mafia] parry: I know the mob controls the big rackets. eliza: Who are you really talking about? parry: Have you ever really thought about the Mafia? eliza: Suppose you ever really thought about the Mafia? parry: Let’s talk about something else. eliza: I am not sure I understand you fully. parry: You keep asking me the same things, why not change the topic? eliza: In what way? … .… .… . parry: I am getting tired of answering the same questions over and over. eliza: What resemblance do you see? parry: Why do you need to know that? eliza: What do you think? … .… .… . parry: You harp on the same questions too much. eliza: What does that similarity suggest to you? parry: I don’t get you. eliza: Do you wish that you did get it? parry: It’s about time you showed some interest in my feelings. eliza: Oh, I showed some interest in your feelings?
