There's a joke that everyone who tries to solve their own problem makes a dating app. I think that's half of the problem - the people making the apps are amateurs, while the happily married people don't feel a need to make them.

Catfishing has always been around. AI doesn't make it much worse. It's a temporary problem.

Compatibility is overrated IMO. I'm probably incompatible with my wife on many levels. I don't know a lot of people who are fully compatible with their spouses. If he's not abusive, if she's not manipulative, it's probably going to work out.

Part of the romance is wanting to make it work despite the obstacles. If I could optimize for anything, it's for platforms matching people willing to make it work. Coffee Meets Bagel does a decent job at this by forcing the two to not talk with others. Muzz goes even further and lets you meet the dad to propose marriage.
