This. Right now, I'm assuming you're all humans, and so are all my coworkers, and the other people driving cars around me and etc. How easy is it to dehumanize actual humans? If I don't try to remain polite in all written English conversations, including the LLMs, that's going to trickle over to the rest of my interactions too. Doesn't mean they deserve it, just that it's a habit I know I need to maintain.
