Either the studios will surrender and pay the respectful amounts, or they'll find a cheaper and easier less problematic way of getting their business done.

It could spur the use of AI, creating a catalyst for a snowball/domino effect where movies will be written by an AI, then movies start to have actors return from the dead with AI, both visually and with audio voice manipulation (although this is already happening in drips and drabs but with CGI, like Tarkin in Rogue One). In time AI will become more definied and more polished and perfected, even more if it has the financial backing of movie studios. Then it could shift over to TV shows. You could even find that long dead show hosts miraculously return from the grave, continuing their job as if they were still with us.

Although.. That Agent Elvis TV Show really could've used an AI to give Elvis his proper voice.. since they didn't even try to find someone who sounded like Elvis to cast as the voice actor.
