The thing about that though is that no one cares.
Listeners do not care, anyone who would hire composers does not care, etc.
One thing that can be given to the individuality camp is that AI does not seem to be able to, and may never be able to, do something like compose an entire album that has a consistent style. So it composes one piece of music that you like, it can't compose more that retain the same "fingerprint" that Beethoven or Metallica has throughout their work. People will probably find that disappointing.
But not disappointing enough to turn people away from AI.
Because all that people ultimately care about is whether or not it sounds good.
However, it could be that this is all a moot discussion as the sustainability of AI is coming more and more into question. These programs require large data centers to maintain, and they are pretty much all spending more money than they are making; it's mostly investors keeping them above water. At some point prices of the services are going to skyrocket because they will need even more hardware, electricity and such to support literally everyone using just a handful of services. Private individuals, big companies, everyone.
Then you must consider something like ChatGPT. ChatGPT is not replacing search engines because why pay to ask the robot when just about anything you want to know has already been written by humans and is freely available online?
The other issue is that AI cannot presently make changes in small details; it has to reinvent the entire image or whatever. If it were capable of doing small, specific tweaks, this will exponentially increase the demand for processing power. So far, despite the fears that it will destroy all the jobs, it has not proven to be a more profitable, efficient or economical alternative to people.
