Or, I digress, it will be distinguishable from human work but because it's so much better than anything that a human could have ever created. These AI tools that we have now are as dumb as they will ever be. If we ever reach AGI or superintelligence or whatever—or even if not, even if these tools just advance for 10 more years on their current trajectory—it's easy for me to imagine some scenario where the machines can generate something so perfect to your liking that you just prefer it to anything a human ever would have created, storytelling and all.
You can take the general case where AI can just generate a better movie than a team of humans ever could plausibly generate. After all, AI doesn't have any of the physical constraints of a movie studio—the budget, the logistics of traveling from location to location, the catering, the fact that the crew has to sleep, has to coordinate schedules, all that. AI, with some human involvement or not, could just keep iterating on some script on a laptop overnight until its created an optimized version which is more satisfying to humans than any other human made movie ever created. Or in a narrow case it could create the perfect movie for you, given what it knows about you and your interests. All human movies would look inferior.
For my kids, who I'm sure are going to grow up in a world where this type of art is embedded everywhere—and where the human version is almost certainly going to be worse—I don't think the desperate cries to see the last scrap of human ingenuity will mean anything. All of these people throwing rocks at Waymos and others boycotting companies for generating ads rather than shooting one with a video studio; it's so obviously helpless, desperate and obviously futile in the face of what's coming.
I mourn the future that seems plausible here but I also welcome it as inevitable. The technology is coming, and people are going to have to adapt one way or another.
When I'm listening to music, looking at art, seeing a play or a short film I want to feel connection to the humans behind it. AI is by definition missing that connection. That's what makes me retrospectively vomit at AI writings like these. That connection requires that the humans behind it are imperfect, the solo can have one or two sloppy notes, but at least it's genuine interaction. We have seen this same yearning for connection with all the "Don't use LLM to comment, use your true style of writing with its flaws" rules.
I'm 100% certain mainstream studios will be producing "perfect" content with AIs just like current mainstream pop stars have 10 ghost writers working on each song to create "perfect" songs. The good stuff will exist in the fringes as always and I'm ok with that as I've already been for years.
And the future may not be as settled as you think it is. Leaders try to sell you their vision of the future by saying it is settled and that things are certain, but that is because they want you to believe that, because if you and the masses believe so, it's more certain for the future to settle the way the leaders want. But you can also actively refuse that future and find a different future that's worth believing in yourself.
