I despise AI-generated audio, video, and text.
That said, yes, in many use cases, AI-generated music *will* replace human-made music.
I don't think AI can replace human art. It lacks soul. It's too perfect. It's shallow like a pretty girl friend who has never had a serious thought or suffered something painful and overcome that pain.
Humans have depth and pain and soul.
Art is so much more than a pretty picture.
