I think to me the weirdest and most unexpected (not so much in retrospect) AI use is that people will use it all day long to navigate chat conversations with their boyfriends/girlfriends, having it suggest romantic replies, etc.
I expect people to be lazy, but that we'd outsource feelings was surprising.
I have a family member who worked in a Hallmark store when they launched a custom card printing service (in-store, select the cover art and write your own message, printed on a card).
She says that about 75% of the custom card customers would ask her what they should write for a message.
She wrote messages of friendship, love, birthdays, graduations, congratulations, sympathy, etc. To support her coworkers on other shifts, she filled an index card box with several dozen canned "custom" messages for Hallmark customers to choose from.
Somewhat separately, she reports that working at Hallmark is a good way to make a misanthrope out of an intelligent teenager. To which I reply that most of the intelligent teenagers I knew were already misanthropes! But the stories she tells, particularly of Christmas ornament hysteria, are hysterical.
Hmm, LLMs have helped me understand the perspective of my girlfriend better, and taught me to be a better listener and how to not act in various scenarios. I do not really use LLMs to write replies to my girlfriend, however. I have used it before to make some corrections, but the essence remained, and it came from me.
