You don't need AI to generate hack art. Corporate Memphis aesthetic has been around for ages precisely because its cheap, hacky clip-art you can apply to ad copy in order to give it a hint of life without spending much money.
These AI models make the new art comparatively dirt cheap (if you ignore all the negative external costs) without relying on the even more cheap and bland techniques of the past. It's absolutely "better" relative to what's come before.
This applies so much in so many different areas of society that we should have a Unicode character that’s like an asterisk but this is the only caveat that it represents.
