Yep, AI art is just getting through its irrational exuberance phase. It was (and sometimes is) impressive to create art in a style most of us can't draw or paint in. But AI models tend to produce very similar results unless very specifically prompted. AI art creators are also using a lot of other tools (like ControlNet, which allows you to replicate composition elements from another work) to break out of the "default AI model" look.
All of that points to an immediate future where AI art is seen as low-quality and instantly identifiable, except where AI art creators have spent a fair amount of time customizing and tailoring their image. Kind of like...real artists using pre-AI modern tools like Photoshop, filters, etc.
