On the same note, I was talking to someone a few days ago who was telling me about how many of her girlfriends use Tinder to essentially have virtual boyfriends. She explained that in many cases they meet guys via Tinder, move to text-messaging, and the relationship never progresses to in-person meetings. They simply love having someone on the other end of their phones to talk to. The knowledge that someone is there at almost all times seems to be comforting and addicting. Kinda crazy, but again this kind of thing is only going to become more and more common due to the fact that technology is in everyone's pocket from a young age now.
The question I ended the conversation with was something along the lines of, "Do you think they care that it's an actual human on the other end? Would they be ok with really convincing AI?"
Food for thought.
