You are correct, Tinder is designed keep you on hook, sustain finger-swiping reflex, and all that.

But I've been pondering from a zoomed-out, conspiracy-ish perspective. If FB merges with dating apps, I bet there will be no premium accounts at all, as revenue from them won't matter much. Because, having FB's stat-models of social groups combined with dating app leverage, they can be forced to gravitate towards or divided not only by superficial forces such as personalized news-feeds and ads, but your children potentially will become a content for you and the product for population, recycle.

The biological function of love is to reproduce as many DNA of yours as possible, or support closest neighborhood DNAs as well. It is interesting what it will be like when we'll have substituted natural love with statistically predicted one? We've been doing this already with politics and culture, only this time it will be more real-time.
