This is also why SAG-AFTRA [Screen Actors Guild-American Federation Of Television And Radio Artists] plus WGA [Writers' Guild Of America] are protesting nowadays. The AMPTP [Alliance Of Motion Picture and Television Producers] are endeavoring to use this technology so that they will not have to PAY actual human artists for their talents, skillsets, and profession. In fact, they want to use (and in most cases ILLEGALLY) the likeness of these professions, whether they are foreground/top billing or background/extras.
IMPHO, modern technology can be good--but only up to a certain degree where it doesn't ensure damage to people's livelihood and quality of life. As the old saying/adage goes: "Too much of a good thing can not good for you!".
