The talking parrot can only answer by repeating something it heard before.

Another question you could ask is “What’s the difference between a conversation between 2 people and a conversation between 2 parrots who can answer any question?”

It doesn't only repeat things it's heard before. Have you ever talked with an LLM?

I had ChatGPT design a programming language for a specific uncommon purpose and then use it. It's creative enough.

Can any question be answered? As long as any reaction on a question is considered an answer, then I see no difference between a human and a parrot.
