I remember that one dude they interviewed like 10 year ago who basically made his own algorithm to find the perfect match on I think several dating apps including Tinder.
It would also tell him a ton of information about each person from web scraping other profiles and stuff.
He said he got about 200 dates that all went really well because he knew everything about the person, and the algorithm would sift through thousands at a time to match someone he wanted.
After all that, he still never committed to anyone, eventually stopped his scripted thing, deleted all his dating app profiles, and met his future wife months later IRL by complete chance lol.
