Yeah I've heard this story before. What's actually going to happen is that Spotify and every other music streaming service will be filled with 50 million functionally identical AI generated songs made by people looking to scrape off a few cents when people listen to them by accident.
I don't really want "anyone" to make music. I want people who are good at making music to make music. Yeah we should remove barriers for those people, but honestly nothing beats practice and dedication. Tech seems more and more focused on regurgitation instead of creation.
