I think this has become slightly more nuanced as of late. For example Synthesizer V now has an AI edition that produces retakes with deep learning.
I wonder how people will feel about this long-term as it blurs the line between generated from scratch and tool-assisted. Clearly the intent is to make it easier for producers to get the results they want. How easy is too easy?
I believe in the near future there will be more discussion about specific parts of songs being derived from AI even if the rest is traditionally composed. Because that is the natural result of creating more efficient tools to solve specific needs that artists have, when "generate my song for me" is not an option they would ever consider (given today's rapidly changing norms, at that point it becomes an issue of integrity over efficiency).
I think it is also interesting how revered Vocaloids have been in certain fandoms stretching back to the late 00's in spite of their artificiality. Whereas a lot of the autogenerated content today is derided for being artificial, "not the real thing." I guess because the vastly wider gap and set of limitations of Vocaloid compared to human singers causes creative workarounds that wouldn't be considered otherwise. But the creator is the one who needs to plan and execute those workarounds, as it confirms to their artistic preference.
Maybe in the future the AI art tools that are seen to be most ethical are the ones that preserve the artistic vision of the user. An aspect that artists are lamenting the loss of. Less outsourcing and more deliberate collaboration.
