An LLM is not a pet, but there are definitely people out there treating it like one, and I am not sure how well this is going to work out for them. Not because it is wrong to treat a text box you can hold a conversation with as a conversation partner, but because the capacity to activate the weirder corners of human expression - obsession and delusion - seems to be much higher. And it's an unknown quantity.
I would also like to introduce HN to what I'm calling the Brian Conley test: if you can see a hand up the back, it's a puppet. That is, a lot of LLM interaction is gated through businesses run by humans with profit motives and unclear morality, and you need to proceed accordingly or you'll get scammed.
This is even more apparent if you read this post closely. Look at that personality prompt. It's going to effectively tell a story and start to imagine itself in a role. If that prompt said "Talk like a pirate", it wouldn't be bad for you to say it's acting like a pirate.
Anthropomorphizing themselves is at the core of how these things work, sometimes in subtle ways.
That's spot-on. It is a mistake to think that LLMs have human feelings. Their behaviour is based on narrative descriptions learnt from human texts, without experiencing those feelings first-hand.
A useful way to understand them is as systems that write stories about human characters. We know the characters are fictional and no one is actually experiencing those feelings, but we can still judge whether the portrayal is realistic or whether it contains logical or emotional inconsistencies.
