> is it the prompt you once wrote?

Yes, but also the prompts you give after, and the iterations you continue to do. Art is rarely something you build once and forget about. A lot of that going on in AI no doubt, but the builders who polish their work and strive for perfection are still the builders they were before AI.

You mention the novel writer and yes that person who's great at writing novels will create great art. But the ones that are 80% of the way their, but maybe can't nail the ending, or segue into different plot-lines, can now create great art and have AI get them there. Subconsciously, they will get better at those things by using AI and seeing the result.

I'm always reminded of that I, Robot scene where the scientist says "you must ask the right questions." And that is true now more than ever.
