When the ELIZA chatbot came out (1964), some users claimed it was intelligent and sentient. Then, they were shown the diagram that describes its behavior. Even after that, they kept insisting it was sentient, etc. Some people just want to believe bullshit.
When you interact with an LLM (or Eliza) your brain is doing a lot of heavy lifting, without you even realizing it. I think we tend to infer more intelligence than is there, in the same way we see faces in clouds.
ELIZA replies to almost everything with questions. So ELIZA is constantly prompting you to do the work required to continue the conversation.
