People talk to their pets, plants. Their cars or other inanimate objects even. Anthropomorphizing stuff around us is a natural thing to do. It might be irrational but it just fits the way our brains work. The natural way to interact with an LLM is to pretend it's just another person. And LLMs are of course very good at emulating that to the point where it becomes hard to tell the difference. Which of course is the basis for some scams. The Turing test is considered a bit inadequate at this point. It turns out people are quite easy to mislead and manipulate.
