I'm mostly seeing people who lack the skills or means to create their own works go nuts with prompting gen-AI tools, but it rarely strikes me as creative in either the 'having the ability to create' sense — they've outsourced that — or the 'original, expressive, imaginative' sense.
Creativity is not just having the idea, it's bearing that to fruition in you own manner (or that of a group of people). Gen-AI outsources the 'creativity' needed to get what it generates. The prompt wrangler provides only the prompt; the rest is drawn from the training data.
The way people are using gen AI is way more creative than typing in a prompt, and it is no different than electronic music producers, it's an arrangement of discrete elements they do not necessarily produce themselves.
