The day is coming (and not too far off I predict) when human actors will, to some extent, be replaced by those which are computer generated.
Producers can save a lot of money by not having to pay “movie stars” loads of money, when they can hire a company to “create actors” on a computer and then insert them in a movie.
How will we be able to tell the difference?

I thought that would happen with animation. It hasn’t yet.
