Dynamically generated, personalized content already exists in the form of video games. Yet it is not notable when an NPC remarks on my unique gear, achievements, etc.
Technology may eventually enable easier remixing of art to personal tastes. However, this has also existed as long as art itself.
What people look for in the artist is their uniquely curated tastes, human connection to the person themselves, and a sense of community with fellow fans.
A machine that creates everything for everyone can provide none of these. Its output will be products, not art. It will have customers, not fans.
