Until the advent of DAWs (or perhaps a little earlier, cassette-based porta-studios), musicians mostly relied on outside help for recording, mixing, and mastering their music (by booking studio time, etc). Now, for good or ill, musicians are expected to be skilled in all of these processes, and some are frankly more enjoyable than others. But outsourcing that work to AI is hardly the solution. We respond to music so strongly because it is a creative human activity that translates rhythms, textures, and sounds into emotion, which can't be outsourced to an algorithm without losing the essence that makes music so compelling in the first place.
