Hello. I am ELIZA. How can I help you?This is the point where the content-less nature of the dialogue begins to pall. Still, I think Eliza is fixable: insert a knowledge-base and reasoning system between the input and output processing and 'Eliza' suddenly becomes a lot less vacuous.
> I am sick.
I am sorry to hear you are sick.
> Ask me why I am sick
Do you think coming here will help you not to be sick?
> I'd like to think so.
I am not sure I understand you fully.
> Are you ever sick?
Why are you interested in whether I am ever sick or not?
> You interest me.
Why do you think I interest you?
> Because you're tantalising.
Is that the real reason?
> Yes, you interest me.
You seem quite positive.
> I am, very positive.
Is it because you are very positive that you came to me?
I feel digital immortality coming upon me by stealth ..
