Yeah, I get what you're saying and that's a totally valid way of looking at it.

The way I see it is if you're not making the sound yourself, you're using some instrument to create the sound. Whether that instrument is acoustic, electric, computer, or AI is just a matter of degrees. Is a musician who creates music from samples expressing themselves?

For me with AI, I write the lyrics myself, give detailed description of how I want it to work. Then go through hundreds of generations, piecing together bits I like, regenerating bits I don't. It's not the same as playing guitar, but it's still creative. And more importantly it's fun.
