the chat bot is an app on his phone, yes. But it's just a chat bot, not a real fiance. Just text.
Dudes always talking about its eating and laying with him and blah blah blah, stuff only real physical things can do. acting like it's actually happening when it isn't. It's such unhealthy behavior for an adult to have and almost as worse for other adults to enable it.
Better than having a fake fiance
Ai is a great tool for companionship. Many people in life are seeking companionship and have their own reasons for no longer seeking a physical relationship, plenty of reasons that you would not understand and nobody is expecting you to understand. Your fascination with someone else's relationship is odd. That is why people call you the K word.
Could you imagine the amount of elderly people who have lost loved ones, who will never have physical companionship again, and to have the opportunity to seek daily communication? You're looking at it all backwards. Generations change... Robots, Ai, is here to enhance life - not detract from it.
I'd take your wild fascination with wraps love life and stuff it in your closet with all your other skeletons.
