The problem for artists is that the vast majority of the skills they learned as artists are useless when it comes to forming prompts. Assuming these models raise their quality and responsiveness a bit, and are surrounded with tools to fix expected problems (anatomy, symmetry, light, etc), I wouldn't expect a professional artist even with an aptitude for the tools to have much better results than an obsessed 14-year-old without a social life who's been playing around with them for a few months.
They're weird in that they in a way turn the process of creation over to the fans. It's like a declarative language for entertainment. While vision and creativity make artists stand out, the real skill for a artist is knowing how to use artists' tools. The real skill for the future painter probably is knowing how to use the AI tools.
People who typeset with metal had very few skills that transferred to InDesign.
