Games will be photorealistic within a couple of decades, so you will have AI generated people who do not exist, never have existed, yet look like actual video footage of a real person walking around, talking and communicating with you.

Sometimes I do wonder if it would be harder to shoot a character in a game who looks and sounds like a real human being. The ethical implications ARE sort of interesting once you actually venture all the way across the uncanny valley.
