Hah, I like the idea of showing up to a blind date and opening with "So our LLMs told us we'd get along great, huh?".
A short story idea that's been in my head for years is a Google (or whichever all-knowing system) algorithm that gets 2 people to meet by showing them the correct ads to get them out of the house and to an e.g. concert. Fleshing it out: they get into conversation because they're e.g. both carrying books by a particular author because again they found this author through a Google ad. And 3 weeks later they ran into each other again at another event advertised to them..
