You can make a person look real with computer animation, but a lot of it lacks soul, charm and charisma. A programmer would have to be very talented to recreate a scene that was very realistic, wet, hardcore and fooled people 100%. The reason porn works is that guys want to fantasize about fucking these hot girls. When it turns out the girl is just a piece of animation, a lot of the fantasy goes with it.
