If it's trained on and emulates the behaviour of people, and develops a memory of interactions in order to better serve requests, being "polite" is likely a wise idea if you want to have a useful relationship with your agent(s). People are taught a form of manners already, when interacting with desktop computers, because they display complex behaviour and "being rude" (e.g. Installing random software or poking about in internal settings without understanding of what you're requesting) will result in failure or, at a minimum the system behaving oddly towards you. Further, you seem to assume the these systems will be controlled by and owned by billionaires and we'll only be able to rent access. That's an even worse problem than people treating machines with complex behaviours like people (because they can't tell the difference!) - that's billionaires treating people like machines, and then blaming it on people acting as people do! This isn't a problem with AI and how people treat machines, this is a problem with giving sociopathic rich people more power via sole control of what is possibly the most democratising technology we've ever invented. Make sure your pointing your rage cannon at the right target, eh.
