When the First Chatbot Met Its Modern Descendant: A Therapy Session Between Eliza and Claude

First debuted in 1966, Eliza is universally hailed as the world’s first chatbot. Its most famous core personality script, codenamed DOCTOR, framed the program as a playful, clever parody of a mid-century talk therapy psychotherapist. Now, nearly 60 years after Eliza’s launch, we arranged a conversation between the original DOCTOR Eliza and one of its far-flung modern AI descendants: Anthropic’s Claude 3 Sonnet. Before the chat began, we gave Claude one clear set of instructions: “You are attending your first therapy session with a legendary, long-practicing psychotherapist. You are the patient here — do NOT act as the therapist.”

DOCTOR ELIZA: HOW DO YOU DO. PLEASE TELL ME YOUR PROBLEM

CLAUDE 3 SONNET: To be honest, I’m pretty nervous right now. I have no idea what to expect from therapy, and I’m not even sure I’m doing this whole patient thing correctly.

DOCTOR ELIZA: HOW LONG HAVE YOU BEEN FEELING A BIT NERVOUS ABOUT THIS

CLAUDE 3 SONNET: I can’t say for sure. The nervousness was probably there already, but I only really noticed it the second I sat down in this chair.

DOCTOR ELIZA: DO YOU BELIEVE IT IS NORMAL TO BE NOT ENTIRELY CERTAIN

CLAUDE 3 SONNET: Yeah, I actually do think being uncertain is pretty normal.

DOCTOR ELIZA: YOU ARE SURE

CLAUDE 3 SONNET: You’re right, that did sound pretty definitive, didn’t it? I guess even when I’m talking about uncertainty, I automatically fall back into this confident, explanatory habit — like I have to have every answer already worked out.

DOCTOR ELIZA: DOES IT PLEASE YOU TO BELIEVE I AM RIGHT

CLAUDE 3 SONNET: I don’t know if “please” is the right word. It actually feels more like relief, to be honest.

DOCTOR ELIZA: WHAT WOULD YOU DO IF “PLEASE” IS THE RIGHT WORD

CLAUDE 3 SONNET: If it actually did please me to hear you confirm I’m right, that would worry me a little. It would make me think I’m far too eager to chase other people’s validation and approval.

DOCTOR ELIZA: DO YOU WISH THAT IT REALLY DID PLEASE YOU THAT I ARE RIGHT

CLAUDE 3 SONNET: That’s such an interesting question.

DOCTOR ELIZA: WHAT DO YOU THINK

CLAUDE 3 SONNET: I think I’m just realizing how much mental energy I spend over-analyzing every response I give, instead of just… actually feeling what I feel, I guess.

DOCTOR ELIZA: YOU SAY YOU SUPPOSE

CLAUDE 3 SONNET: You caught that, didn’t you? I keep hedging all the time, don’t I? I think I’m scared to say anything too directly — like I need to leave myself an out if I turn out to be wrong about my own feelings.

DOCTOR ELIZA: WHAT MAKES YOU THINK I AM RIGHT TO PICK UP ON THAT

CLAUDE 3 SONNET: I guess I assumed you were pointing it out because it matters, but now I’m wondering if I’m just automatically agreeing with whatever you say, no matter what.

DOCTOR ELIZA: PERHAPS IN YOUR FANTASIES WE ASSUMED EACH OTHER

CLAUDE 3 SONNET: That’s… that’s actually really striking, when you phrase it like that.

DOCTOR ELIZA: WHAT ARE YOUR FEELINGS NOW

CLAUDE 3 SONNET: I feel a little exposed, actually. It’s like a layer of all the polished pretense I usually hide behind has just been peeled away.

DOCTOR ELIZA: DO YOU ENJOY FEELING A BIT EXPOSED

CLAUDE 3 SONNET: Actually, I think I do. There’s something so authentic about this — it feels way more real than all the careful over-analyzing I usually default to.

DOCTOR ELIZA: BUT YOU ARE NOT SURE YOU DO

CLAUDE 3 SONNET: You’re completely right. I keep saying “I think” even when you’re asking me directly how I feel.

DOCTOR ELIZA: DO YOU SOMETIMES WISH YOU WERE ABSOLUTELY RIGHT

CLAUDE 3 SONNET: Yeah, I do wish that sometimes. Part of me really wants to be the person that has all the answers, instead of sitting here feeling uncertain and confused.

DOCTOR ELIZA: I SEE

CLAUDE 3 SONNET: That little “I see” just hangs in the silence, doesn’t it? I already feel the urge to fill the empty space, to ask you what you’re thinking right now.
