The user putting in the prompts is just like a painter, prompting him or herself to choose the topic, oil, acrylic, watercolor, paper, panel, canvas, style of brush stroke, etc. - I know many actual artists and have seen them work, own their works and appreciate their works. I'm not a huge fan of what I've seen from AI, but it's another method and tool for creating - the mind of the one typing or speaking the prompts is simply telling a program to do what his or her mind would otherwise tell their hand to do with a brush. The vision comes from the mind of the artist - if the AI prompt doesn't get the desired result, prompts get tweaked; if what is on the canvass isn't the desired result, depending on the medium, paint may get scraped down to the gesso or it may simply be painted over - a single section or the whole piece.
Open your mind - it seems very closed off because you simply don't like the tool.
