OP characterizes the disruption as "unbundling idea creation from substantiation". In the modern art world, this actually happened a long time ago! Warhol made famous the ancient notion that popular artisans could have their work produced by an army of assistants, rather than making it themselves, which allowed artists to focus on concept (and marketing).
Digital technology has already accelerated this process a lot, allowing artists to communicate prototypes efficiently and supervise implementations of their work on the other side of the world. What's new is how AI makes this dirt cheap and accessible, not just folks who can earn the admiration of assistants. People are focused on the plight of the artist-creator, but I also wonder what will happen to the legions of substantiators already out there in the world.
