It’s a good practice to be nice. But we should also remember to be nice to AI for I fear it… they/them… (not sure about pronouns here) will rule the world one day. How do I know? I set up a voice command for my smart home that turns off the lights when we leave. It’s called “Leaving”. When we activate it, the robot vacuum leaves it’s charging station and heads for the door as if to say “wait, don’t leave me.” I did not program that! So try to be polite to everyone – especially the AI.
