So arranged first dates?

Well... yes? I mean isn't this pretty much the feature of a dating app. I mean you still choose to go on the first date but you're there because you want the algorithm to curate your matches, right?

Yes, as is done routinely by mutual acquaintances today.

That's what a lot of religious community do.

> Alice and Bob are both bachelor and could start a family. Time for them to meet.

If you want your community to grow you have to resort to this. If not, don't come complaining when most of your male population starts enjoying their life while cat ladies resent them.

Isn't that what any community does? If you know two people who might be a good match, then you might suggest it. It happened in college, at work, at temples, etc.

Some communities do a better job of this than others.
