To be fair, it was more a "wow look what the computer did". The AI "art" was always bad. At first it was just bad because it was visually incongruous. Then they improved the finger counting kernel, and now it's bad because it's a shallow cultural average.
AI producing visual art has only flooded the internet with "slop", the commonly accepted term. It's something that meets the bare criteria, but falls short in producing anything actually enjoyable or worth anyone's time.
It sucks for art almost by definition, because art exists for its own reason and is in some way novel.
However, even artists need supporting materials and tooling that meet bare criteria. Some care what kind of wood their brush is made from, but I'd guess most do not.
I suspect it'll prove useless at the heart of almost every art form, but powerful at the periphery.
