I don’t think these tools eliminate the artists. They just remove their need to waste vast amounts of time on menial and repetitive tasks like UV unwrapping and rigging so they can focus on creating what they should be creating: art. If you look at most tools that vastly improve artists productivity, they often have one thing in common: eliminate the need to deal manually with the gory technical elements that make up computer graphics like polygons, normals and UVs: sculpting tools, terrain tools, cloth design tools, hair styling tools, etc. Those not only save time, they also allow for more consistent results.
They also don’t eliminate the need for skill and talent, they merely change the kind of skill and talent that is required. For example, someone with no experience in 3D modelling but skilled in sewing and apparel design can actually use Marvelous Designer to create clothing for game and CG characters that will probably look way better than that done by an experienced 3D modeller with zero apparel design experience.
