In this spirit, I think Tiktok would actually be a tremendously good matchmaker for finding either friends or romantic partners. I think a lot of their recommendation AI actually figures out what you might like ahead of actually showing it to you, by trying to sort you into a cohort of people with very similar tastes. Which is why as a new user its sometimes scary how Tiktok can almost predict what you might like. E.g. people into cars, 30-40 yrs old, rural probably also like DIY.

That's a good point. A simple k nearest neighbors search of users would likely turn up very similar people to you even if you don't explicitly include any demographics.
