I’ll argue the opposite: there is no need for human actors anymore. The entire story will be CGI, and you’ll not miss the actors. They, of course, will go on strike, demanding that taxpayers subsidize their obsolescence, and make grand moral arguments about art.
I’ll say it again: acting is dead. Long live the illustrators and writers. (I do agree that Hollywood is out of ideas, which is a different issue. When you turn against virtue, you can’t have a hero; without heros, there are no stories.)
