Back in 1991 I wrote a short story...
About a blockbuster movie that was in production, and then its mega-star lead actor dies in the middle of filming... in a panic the studio turns the emerging CGI technology to just simulate the actor digitally- saving the film which smashed box office records...
Overnight, studios realize it is cheaper to digitally design perfect leading men and women, rather than pay 10's of millions to temperamental actors...
Blockbuster actors are suddenly unable to find work... Meryl Streep becomes a cab driver, Arnold Schwarzenegger becomes a short order cook at a diner...
