I am pretty sure that this is filtered out. On a related note I think the whole autonomous agent metaphor is a net negative. It is a pure probabilistic token prediction function. You can run 100 in parallel, add or remove chat history as content to explore the output space. That is much more interesting and powerful than a single sad stateful clippy agent that one might act polite to.
Because I want to be a polite person by default. It makes life nicer fot everyone involved and gives extra effect when I (rarely)choose not to be polite. I believe any interaction with anything is a little training, and I want to do it in the right direction.
I presume I would if it would talk to me (playing ads doesn't count). I am known to absent mindedly apologize to my table if I walk into it(sample size of 1). I also try to be polite to my cats(they don't seem to care either way as long as food appears). Make of all this what you want.
