You are completely right but you missed the essential point:
Soon A.I. music will be undetectable by most and consumed as usual human production.
This is the problem...Like non labelled fake meat, like UBI, like digital control etc...
Human "style" is linked to a controlled "imperfection" gesture, which become meaningful because chosen by a human soul.( think about your written signature, your specific way of walking, and the way you can create)
But this "imperfection" can be imitated to "perfection" by machine...
All the A.I. question is related to the soul and the human free social fabric existence, versus hive controls and no-soul consumerism...
Terminator is not the worst scenario nor the most probable for now, destruction of human soul is...
What is extraordinary is that many dont even recognize the soul exist and what is their own soul compared to their ego-body...Then transhumanism is for them not an abomination at all , and techno-cultism is conflated with "science" ...But it is not...
AI doesn’t create art… without its human intelligence repository it is inert.
AI music is just an algorithmic rearranging of a library of other intellectual property.
