If you want an artist you can discuss a project with, who will respond to your concerns, make relevant contributions and produce something close to exactly what you need, hire a human.
If you want semi-random stuff, go with the AI.
If you're an artist trying to get by making semi-random art and hoping someone will buy it, time to look at refining your business model and asking what your artistic contribution really is...
Art isn't about showing you what's there - phototgraphy has taken that over - it's now about showing you what could be there and what should be there. Art is about the communication of complex concepts. Sure you can take a bunch of random stuff and try to reverse engineer a meaning into it - humans a pretty good at that, but it's about as artistic as reading goat entrails. A good artist should understand at least some of the meaning they are putting into their work and be able to explain that, at least partially, to other people (although for really great art, they should be able to get that communicated meaning from the image).
Anyone tried suing the folks that make/run these AIs for stylistic for copyright infringement, or fraud? Unless clearly indicated otherwise, an image in the style of one of the old masters is a forgery...
