I'm trying to understand a (text/telegram) scam...

So I'm in the USA - I often get text messages on my cell phone, or I'll get messages on telegram. It's always a pretty girl of some sort, and they'll "message me in error" - a few of them I've tried to talk to for 2-3 days to find what the end goal was, and there never was one... Anyone know what this scam is? A few of them I would capture their IP in various countries, obviously, I know these are not pretty women trying to talk to me... Are these AI/chatGPT bots of some sort? It's like they're somehow farming a conversation for a long period of time, but I'm not getting it...

Wonder if anyone knew what this scam is?
