I think it depends on the self-awareness of the user. It's easy to slip into the mode of conflating an LLM with a conscious being, but with enough metacognition one can keep them separate. Then, in the same way that walking on concrete doesn't make me more willing to walk on a living creature, neither does my way of speaking to an LLM bleed into human interactions.
That said, I often still enjoy practicing kindness with LLMs, especially when I get frustrated with them.
It seems like by default, the LLMs I've used tend to come across as eager to ask follow-up questions along the lines of "what do you think, x or y?" or "how else can I help you with this?" I'm going to have to start including instructions not to do that to avoid getting into a ghosting habit that might affect my behavior with real people.
I think people in general are not all that great at doing this.
Anecdotal, but I grew up in a small town in rural New England, a few hours from NYC and popular with weekenders and second-home owners from there. I don’t think that people from NYC are inherently rude, but there’s a turbulence to life in NYC to where jockeying for position is somewhat of a necessity. It was, however, transparently obvious in my hometown that people from the city were unable to turn it off when they arrived. Ostensibly they had some interest in the slow-paced, pastoral village life, but they were readily identifiable as the only people being outwardly pushy and aggressive in daily interactions. I’ve lived in NYC for some time now, and I recognize the other side of this, and feel it stemmed less from inherent traits and more from an inability to context switch behavior.
If you're rude to an LLM, those habits will bleed into your conversations with barista/etc.
