This is completely and utterly your own opinion, not a fact. I know several people who can't draw for shit, due to various reasons, but now AI allows them to create images they enjoy. One of them has aphantasia (They literally cannot imagine images).

Never claimed it wasn't an opinion. And I fully acknowledge that tools can make creating art easier. Hell, I even support the use of machine learning tools when making art. When used as tools and not as a means of creating art wholesale they can enable creativity. But, I'm sorry, writing a text prompt for an AI to produce an image is not making art (for the person writing the prompt). It's writing a prompt. In the same way that a project manager writing a brief for a contract artist to fullfil is also not creating the art. The AI is producing the art (and by extension the artists who created the works the AI was trained off of). Your friend with aphantasia is not.

This is basically trying to argue there's only 1 correct way to make "art", which is complete and utter bullshit. Imagine trying to say that a sculpture isn't art because it was 3D printed instead of chiseled. It makes 0 sense for the method of making the art to impact whether or not it is art. "Expression" can take many forms. Why is this form invalid?

Again, I never said any form of art was invalid. Not even AI art. Nor do I think AI art isn't art. AI art is perfectly capable of creating something worthwhile by means of its content. It's basing it's output on worthwhile works of art created by people after all. I'm merely arguing AI art is unethical. If you made a mural out of the blood of children you murdered it'd still be art. But it sure as shit wouldn't be ethical.
