Consider a band releasing a new album they've spent 9 months writing and recording. In our post-financial brave new world, they give it away for free. But they'll read the reviews, and get excited if their music is well received. In short, they are hoping to be "paid" in public acclaim.
Now imagine that the minute they release it, some AI system digests all their new tracks, and a thousand randoms start making songs that are similar to the style and aesthetic they have spent time creating. In short order, the number of synthetic AI tracks will dwarf the originals, and the recognition will go to whoever markets their synthetic tracks the best, rather than the original creator.
The only hope I see for artistic creativity is in training custom, boutique AI systems that accurately encompass the Artist's style. But that's not really creativity to be honest, it's more akin to licensing.
