I think your right that corporate stuff (including mass market blockbuster stuff) will increasingly be done by AI. But given a lot of it is currently “written by committee” it’s not really that different. The writer of Halloween 47: The Last Killening might have been an indvidual, but it probably got redrafted by another bunch of writers at different times, and studio execs made changes, etc. It’s unlikely the work of a single visionary.

But I believe that parralel is with industrial food. Living through the mid twentieth century, watching people go from cooking at home to buying frozen, freeze-dried and other processed meals. Or eating in fast food chains where all the food is packed full of additives in some factory a thousand miles away. Some of it was good (being able to get certain ingredients year round, or easy access to food from far away) but a lot was pretty depressing, and easy to imagine a time where we forget how to cook and eat real food entirely.

But that’s not what happened. Sure, some people only eat processed crap, but also people have become more and more obsessed with local, handmade stuff, or authentic or fusion recipes from around the globe. In the 80s/90s it felt inevitable that there would end up being basically 3 beers to pick from. Now there’s an endless wave of craft beers, etc, etc.

So with AI. It will take us a while to get used to. Corporations will use it to make money and make our lives worse. But it will also be a useful tool for help actual people be creative and make things for other humans. And in the end, there will always be a demand for the best, or unique, innovative stuff, and that will probably mean human created, not AI.
