This is her saying actors will have their faces rented for cheap to movies.

This is a total "missing the forest for the trees" statement. If that happens it will be for a VERY short period of time, because it will be cheaper to just generate a new face. She just can't follow the train of logic to the obvious next step because she assumes "actor's faces have value" is a truism.

Say we were making Iron Man in this supposed future world. Why would anyone license RDJ's face when they could just generate a model of Stark's face based on the comics and not have to pay an actor for their face?

And once they're not hiring flesh-and-blood actors for any roles? DEI excuses go out the window. If they make a character look a certain way, it will be a deliberate choice. They won't be able to hide behind the "best actor who auditioned" lies anymore. They had the capability of making the character look exactly as described in whatever the source material was, they simply chose not to.
