"Swiping" has largely replaced computational matching because it outsources the decision to the user and allows for high-through-put decision making. Users set a radius and judge everyone who meets their basic criteria in that radius (or for the lucky, select from the cattle-call of already received likes).
Yes, these apps could be limiting the raw number of swipe opportunities, but this would probably just turn users away altogether for lack of viable matches that fit their criteria.
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.
