This is think-piece for me, and not a fully fleshed out treatise on this subject.
It's factual to say that music made by AI removes at least some level of creative intention from the resulting music. On the question of intention, is intentionality correlated to spiritual and creative evolution? Or, is less intentionality the result of evolution and development? The truth is probably contextual, depending on the individual. Growth can be in either direction.
The intention to use Artificial Intelligence in any field of endeavor is a choice.
The intention to use constructed, hand-built, or human crafted materials is also a choice.
Whereas the effects of a creative work can be the by-product of an intention, it isn't a necessary causal agent of the experience of the work. You can enjoy a piece of music built by hand. You can enjoy a piece of music constructed by AI. It's within the chasm between intentionality and non-intentionality that work produced by AI exists within.
Whether to use AI as a creative tool is decided by an individual's intention - to have a relationship with the entire creative process or to curate the work produced by AI.
Do I want the experience of knowing the subtleties and textures of a creative process, or do I want someone else, or something else, to create a product without those experiences?
Do I want to retain ownership of a process or curate an outcome?
At what level do we cross the threshold between noble experience, experience that guides our evolution as artists, experience that opens new avenues of personal growth and exploration, and mundane experience that means nothing?
Is there such a thing as an experience that means nothing in the context of our personal, creative, and spiritual evolution?
Can we still evolve as artists, creators, humans, removed from process and experience? Which processes and experiences are most beneficial to our growth?
If we increasingly curate our lives and work through the by-products of artificial intelligence, what happens to our personal, creative, and spiritual evolution?
Certainly, experience doesn't end where our tools have taken over. We move on to other experiences, new contexts.
What new contexts will open up as a result of artificial intelligence, and where will our new growth areas lie as humans? What experiences do we want to have even when someone, or something, else could execute a process or produce a work on our behalf?
Perhaps, in a world saturated with AI, like any pervasive technology, its effects will be largely ignored, infused into the fabric of society, until it's weaponized.
The underlying issues of human survival, personal growth, etc, will remain largely the same in a world saturated with AI. We will still search for meaning. We will still desire to be celebrated, supported, loved. We will endure the effects of competition and need some sort of livelihood. We will base our self-worth on internal values, external circumstances, and combinations thereof. AI will not solve the problems of our human nature and self-perceptions. It will not solve the ills of society, which is the by-product of human nature.
Ironically, AI, its use, mis-use, and development, is the by-product of our intention to create it. How intentional are we willing to be in the curation of our own lives and experiences within a world increasingly pervaded by artificial intelligence? Like most areas of human endeavor, each individual will have to decide what they want from their experiences, what to include, and what to exclude.
