Very well said! Creativity is definitely a skill that requires work, and for which there are no short cuts. It seems to me that the vast majority of people using AI for artwork are just looking for a short cut, so they can get the results without having to work hard and practice. The one valid exception is when it's used by disabled people who have physical limitations on what they can do, which is a point that's brought up occasionally - and if that was the one and only use-case for these models, I think a lot of artists would actually be fine with that.

Average humans, sure, don't have a lot of understanding and insight, and little is needed to be able to draw a doodle on some paper. But trained artists have a lot of it, because part of the process is learning to interpret artworks and work out why the artist used a particular composition or colour or object. To create really great art, you do actually need a lot of understanding and insight, because everything in your work will have been put there deliberately, not just to fill up space.

An AI doesn't know why it's put an apple on the table rather than an orange, it just does it because human artists have done it - it doesn't know what apples mean on a semiotic level to the human artist or the humans that look at the painting. But humans do understand what apples represent - they may not pick up on it consciously, but somewhere in the backs of their minds, they'll see an apple in a painting and it'll make the painting mean something different than if the fruit had been an orange.
