I also believe AI is a tool, but I'm sympathetic to the idea that, due to some facet of human psychology, being "rude" might train me to be less respectful in other interactions.
Ergo, I might be more likely to treat you like a toilet.
Are you really in danger of forgetting the humanity of strangers because you didn't anthropomorphize a text generator? If so, I don't think etiquette is the answer
perhaps if an LLM were trained to be less conversational and more robotic, i would feel less like being polite to it. i never catch myself typing "thanks" to my shell for returning an `ls`.
Your condescension is noted though.
I'd probably have passed this over if it wasn't contextually relevant to the discussion, but thank you for your patience with my pedantry just the same.
