But let me put it this way: when LLMs weren't really a thing, I made a Tinder auto swiper. It was about 4 years ago. I think it was around ChatGPT 3.5.

I swiped about 125K profiles. I had a match rate of about 0.75%. I'd unmatch two-thirds (I went through all the pictures and read the bio in full, a few minutes per match). And the rest would stay as actual matches.

This means in my 5 month dating period I had 60 matches per month on average. 50% of them didn't respond, the other did. So 30 chats per month. I had a 20% chance that I'd go on a date with them. I went on about 30 dates in total.

I found my wife through those shenanigans. I wouldn't have found her if I wouldn't have auto swiped because I got swiping fatigue after manually swiping a few thousands profiles myself.

Call it what you will but finding the right partner is an incredibly important decision in one's life. Finding the wrong partner will cost a lot of money eventually.

I can tell this story now because it happened 4 years ago and I don't mind (nope, I never got banned either, Tinder's detection mechanism was laughably bad).

Back then I was building personal software in that vein. I'm done with my dating life as I'm happily married, but there are other problems I need fixed. I build software for that by vibe coding it. And it's saving me time and sometimes it directly saves on cost. Sometimes though it's more a software product that allows me to become a happier person.

One thing in that vein that I haven't build (yet) would be an app that motivates me to meditate. If I can build something that actually works, it makes me happier and therefore (mentally) healthier. That has knock on effects for my career, health, etc.
