“displace the genuine human artistry that is at the heart of copyright protection.”
Please someone think of the poor humans... says the soulless corporate robot haha
There is a significant antipathy against AI at the moment and I fear that these emotions will lead to AI or the "tools of generation" being owned by big copyright holders forever and ever. Basically the common person won't be able to use these tools really. This makes all things AI much worse.
Of course, AI generated music will ultimately lead to the majority of the music business being entirely about marketing and capital, not about creative musical talent. Ultimately you'll have completely artificial "stars" that are simply IP and fully owned and controlled by capital. Which is not what we want, but that outcome is unavoidable. We see the start of this will this hololive stuff (which I'm too old to understand lol).
What is preferable though is that secondary artwork (movies, video, computer games) could use AI generated music without having to pay the music industry. Or that public domain "stars" that anybody can use.
EDIT: This argument assumes that AI will continue to improve and lets say in 10 years it will surpass the quality of music of 90% of human composers... basically that the quality of music will continue to rise until at some point in the future it will surpass the ability of any human composer.
