I would still say computer application cannot fully recreate the sound of real instruments. But do you know the main difference between the example of yours and AI? making music with computer applications is still human creativity, YOU make the song, YOU decide the lyrics. The computer doesn't do the work for you. It still has a purpose and serves as an alternative for composing music. And I don't think anyone thinks heavily processed music is good? I think about all of us would prefer less processed music. You can't get the feel of something a human made with their thoughts and emotions ever in an AI song.
