Chatting with an LLM resembles chatting with a person.

A human might be "empathetic", "infinitely patient, infinitely available". And (say) a book or a calculator is infinitely available. -- When chatting with an LLM, you get an interface that's more personable than a calculator without being less available.

I know the LLM is predicting text, & outputting whatever is most convincing. But it's still tempting to say "thank you" after the LLM generates a response which I found helpful.
