If it's not already a thing, I'm thinking that one day, people will be able to create themselves a virtual 3D friend or a lover via AI. Ain't nothin' like the real thing though, without a doubt.
More than likely one day the few people still living on this pitiful broken planet will be living in caves and killing each other for a drink of water.
There is already a whole subreddit of people having relationship problems with AI. They complain there they are not responding to thier needs or the AI wants sex but they don't feel like sex ATM, or vice versa.
