I shit you not, my mother thanks her Alexa hockey pucks every time she interacts with one and gets an acceptable response. You would not believe the ridiculous, over-the-top replies it's programmed to give when it (correctly) interprets a thank you. The lengthiest one I've heard it shoot back is along the lines of: "[mom gives command]" "Here's [blah blah blah] response" "Thank you Alexa!" "Good morning, [mom's name], you're so very welcome. I'm glad I could help."
I seriously wonder if they've just got a guy (or worse, a team) devoted solely to "pointless courtesy interactions" like this. I've heard the fucker sing, tell jokes, offer to play music or sounds (that she already has -- no upsells, which is the creepy part), etc., all in response to a "thanks." And like I said, it bizarrely never offers an upsell when responding to a thank-you.
But yeah, I assume my mother's buying enough goodwill for at least a dozen human beings in the upcoming AI apocalypse.
