Just try "M-x doctor" in emacs. You get great AI and it's actually useful: psychotherapy! Just to convince you how good it is, here are some excerpts from my conversation with it (these are genuine lines, I start):
I think we are friends, but I am not sure.
Is it because you are not sure that you came to me?
I see... Well, why do you say this is so?
Because she seems to avoid me.
Does it bother you that she seems to avoid you?
Yes, hmmm... so, what makes you believe this is so?
Well, I am getting very anxious about it.
Are you sure that you are getting very anxious about it?
Yes. I'm glad you're getting back to actually trying to help me.
Maybe your plans have something to do with this.
Yes, I want to get married.
Do you really think you might want to get married?
Is it because of your life that you say you do?
Yes. I'm tired of being so lonely.
Are you lonely often?
