By definition of having an AI generate something for you instead of making it yourself, you can’t create exactly what you want. You can probably get it in the ballpark, though. But that’s exactly the same scenario we have today with musicians.
The same way we traded away the profession of painters for photography, it seems like we might be trading away muscicians for generative music AI. Except photography is super useful for lots of things and truly benefitted humankind, and generative music AI… only replaces musicians? I have no idea why we would make this trade, as a society.
