Then the first fully non-human (but human-like) actors will be created and gain popularity. The IP of those characters will be more valuable than the humans they replaced. They will be derided by old people as "Mickey Mouse" AI actors. The SAG will be beside themselves. Younger people will not care. The characters will never get old (or they will be perfectly rendered when they need to be old).

The off-screen dramas and controversies are part of the entertainment, and these will be manufactured too. (If there will even be an off-screen...)

This is the future, and we've been preparing for it for years by presenting the most fake versions of ourselves on social media. Viewers have zero expectation of authenticity, so biological status is just one more detail.

It will be perfect, and it will be awful. Kids born five years from now will never know anything different.
