It’s perfectly fine to like something that isn’t art. Hell, it’s perfectly fine to have a definition of art that can include AI, that’s just a framing for talking about the things AI does well vs. the things it doesn’t. I find that where a human can mix different things together in a way that enriches the whole, AI mixes things together in contradictory ways because it lacks human experience. It’s why, AI pictures usually come out flat and lifeless or includes nonsense details that don’t fit or includes requested details in incongruous ways.

That said, I only know about Hatsuni Miku through my kids. I don’t really know anything about that specifically.
