I recently read that 1/3rd of hollywood jobs have disappeared. 48,000 gone. Most I suspect due to the terrible scold movies and tv shows they make but AI is replacing background players and set design builders etc.
The writing from AI is a rehash of the bad storylines already made.
Some of that is due to the industry shift away from Hollywood. The Arri Alexa digital movie camera was released in 2010. Since then, movie producers had a more plentiful, less expensive, and better filming options than Hollywood could offer. The James Bond movie "Skyfall" (2012) was filmed using Alexa digital cameras and won the Academy Award for Best Cinematography.
Add in Computer Generated Imagery and regular television shows can be filmed against a blue screen (or green screen), cutting back on set construction by instead using digital backgrounds created by lower cost overseas video editors.
