5/ We spent decades working on (and worrying about) machines acquiring human capabilities. The quiet shift may be in the opposite direction -- in talking to these efficiency machines, we could be unlearning how to treat each other as people, and willingly becoming fungible with them, even behaviorally.

4/ However, the difference here is not simply in the absence of politeness markers. It's that when agents make creation so easy (quality aside) people stop valuing the act of creation the way they used to. And in a culture where identity is so wrapped up in what you offer, a drop in how your output is valued will bleed into how you are valued -- so you can imagine less thoughtful managers and colleagues treating you accordingly.
