To use your example of the movie industry, everyone gets the benefits of the effiency gains.
There's twice as many scripted shows today and twice as many movies released despite the average person spending half the time they did 30 years ago watching TV and movies. For less than the price of a 1990s cable tv subscription we can access almost any movie, instantly streamed to our HDR TVs at home, on demand. The digital VFX we expect of a low tier direct to streaming show are better than the some of the best 90s movies (practical effects excluded).
There are hundreds of thousands of people across the world using the 4k camera in their pocket they bought for a few hundred dollars to make hyper specific media and distributing it free on YouTube. They are editing it in cheap or free video editors on their computer or built in to their phone.
It's easy to shit on modern media. With democratization comes slop. There's garbage now just like there was before. But we are absolutely benefitting off the efficency gains of the last few decades.
