Difference is that AI can generate good-enough content most of the time. And that is often enough. It is not like what is sold now produced by humans is especially spectacular.
The script-writing AI, voice AI, actor-image AI will be used to create a multitude of options, and all but one will be thrown away anyways. Perfection isn't necessary, realtime isn't necessary, and a human correcting things here and there is always still an option. Compute resources are also far less limited, it doesn't have to fit in a "car" form factor and power consumption.
Isn’t that what we are asking for though? We know there will be fewer people working in the industry. We want to ensure those who will work will be paid fairly.
