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?
