So if you're a woman in your mid-20s, single, and ostensibly, reasonably good looking, AI can find you a soul mate? Maybe. I mean, you probably give it a lot of information on your preferences and it knows a bit about all the male suitors you ostensibly seek. So there are like ten (or more!) times as many men on these platforms.
What it almost certainly can't do is, do the same for a man who is below average. It's just a numbers game at that point. If there are ten men for every woman, then you need to be in the 10% of the best men that women seek, otherwise you don't have a mathematical shot at finding a mate. If you advertise that AI will find you a soulmate, maybe you increase the female membership and you give more men a chance, but it's still a gamble and most men will still be left without.
Now if it had profiles on all available consenting adults in the world, maybe? But that would be super invasive. And if it told you accurately (as in, with 100% confidence) that your soul mate is out there but they live in another country, and there's a 100% chance they will be right for you... do you take the trip? Or deprive two people (you and this other person) of finding their perfect mate?
