Hollywood Actors are doing what they can to preserve their existence but eventually they will also be left behind - you can't stop the progress.
I wouldn't call the idea of big tech having even more influence on our culture and entertainment progress though. Sounds horrible to me.
that's the wrong question, it is like asking "how many peasants are there nowadays"?
of course there are many more people that do not need to plow the fields all day to provide for their 11 children and that can entertain themselves with arts, that's not the point.
the point is that mass manufacturing easily reproducible standardized artifacts becomes industrial production, which has nothing to do with art.
