How so? It's pretty good, wait a few years and it will definitely be as good or better than human musicians. If you're talking as if it is a treat to musicians, they can only adapt and use such techs to push forward. All professions that require reasoning are endangered, not only music.
I am a musician and I like the technology (even wanted to do research on music generation in uni), but I still think the notion that music generation will surpass human capabilities in a few years is naive.
