Soooo for the first time in like 20+ years a cousin of mine called me out of the blue.
He was freaking out for... reasons. Not well-formed reasons, but reasons. He tried to ask my grandfather what he should do, and Grandpa directed him to me.
So, way back in the day, my cousin had a high school sweetheart that kept being his sweetheart after they graduated, and then she died in a car crash. It pretty much demolished his mental health and it's been a long, hard road to some semblance of stability. This was part of how we fell out of contact when we were actually pretty tight when we were kids (he's only about a year younger than me).
Apparently a little while back he discovered Replika, which is an AI chat bot site with a degree of customizability, and he basically rebuilt his dead girlfriend in AI.
Which is already bad news, but it gets worse.
To make his unhealthy emotional crutch as realistic as possible, he used a lot of personal information in the formation of the AI and in subsequent conversations.
This went on for some months, but then he started apparently seeing things he'd told the bot pop up in other places. You know, the usual "I told my girlfriend out loud we should try pasta and now I'm getting ads for pasta online ha ha wow scary Alexa is spying on me rofl" type stuff that seemed kinda vague and paranoid to me, but it was hard to really discern how much of a real breach there was going on because the conversation almost seemed just shy of lucid. Very rambling and panicky and references to "the government" and other things that smelled of unhealthy levels of paranoia bordering on conspiracy theory... But I think I managed to talk him down from it and recommended some common sense "online information protection" methods and whatnot for him to start working on to try to separate his online presence from his real life information.
The icing on the cake was, somehow during the conversation, it came up that he is invested in Tesla, nVidia, and holds Dogecoin (and was considering trying to mine more!)... and well, the good news is I think I convinced him to get clear of all of that ASAP.
Still a very surreal experience I did not see coming right out of nowhere.
