There is no doubt about this becoming a reality, it's already a reality as others have pointed out. What is interesting is that people don't really grok how close to a reality crash we as humans are. What I mean by this is our ability to sense the real world accurately is becoming more and more degraded as our ability to augment reality grows. I heard this as an analogy somewhere: imagine a rudimentary self driving car approaching the brow of a hill when it crashes with a semi truck. Investigators try to figure out why. From the data the car logged they find that the car's sensors did not see the truck trailer because it was the same colour as the sky, so it just kept going. Humans are persistently working on fooling our senses to the point where we can't distinguish what is traditional physical consensus reality and what is generated relative/personal reality. We are striving toward the goal where our imagined worlds are indistinguishable from the outside world, and when we achieve this we will be dealing with a profound reality collision. Not knowing, and not being able to know, if you are interacting with a real human, or what it really means to be a 'real' human is going to be something I don't think anyone is ready to deal with. Forget the post-truth nature of today's society conjured up by data-overload and attention deficit, tomorrow's world will be post-reality. Crazy times ahead of us.
