It's kind of like the difference between something being enjoyable for you, and something being widely popular?

In a hypothetical world of "AI can produce a lot of extremely high quality art", you can easily find (or commission) AI art you would absolutely love. But it probably wouldn't be something that anyone else would find a lot of value in?

There will be no AI-generated Titanic. There will be many AI-generated movies that are as good as Titanic, but none will become as popular as Titanic did.

Because when AI has won art on quality and quantity both, and the quality of the work itself is no longer a differentiator against the sea of other high quality works? The "narrative/life of the artist" is a fallback path to popularity. You will need something that's not just "it's damn good art" - an external factor - to make it impactful, make it stick in the culture field.

Already a thing in many areas where the supply of art outpaces demand. Pop music, for example, is often as much about making sound as it is about manufacturing narratives around the artists. K-pop being an extreme version of the latter lean.

Was Titanic actually that good of a film? Perhaps I should watch it again now that almost three decades have passed.
