I assume that there's a certain a pride that we all get when making a patch or a song from scratch.
(Lots of other good thoughts not quoted for the sake of brevity, just wanted to partially capture the essence of your post)
I've written about it here, but for me it has always been about the journey, not the output... I like the satisfaction I get from the creation process. I haven't even shared musical output with anyone in a very long time because I never cared about attention or validation from others. Musical creation is an amazing form of escapism for me, and that is all.
I can remember walking into a music store at the local shopping mall with my sister (who is a talented pro musician) when we were small kids where they had "Kimball" organs. We were amused at the thought of someone wanting to buy a musical instrument that for the most part, played itself... or at least looked for ways to take the "burden of musicianship" off the player. I couldn't fathom who would want that, or why it was a desirable thing that people would pay money for. Many years later I was in a different shopping mall and I saw a really old guy in the middle of a food court playing what I guess is something like a modern arranger keyboard. Lots of mediocre music coming out of the thing with very little effort on his part
... but you know he really seemed to be having fun, and I realized he is "on that journey" described above, and good for him.
In the 80s we heard about how computers, algorithmic composers, drum machines etc. would kill the music industry. I always felt that the focus on technology was missing the point... music composition in my mind at least is almost always an expression of human feeling, and while the technology to fake that might be interesting, I knew as someone who had already been programming computers that even the best AI of the future would not reach the depth of complexity of human feeling and emotion.... ever actually.
Musical technical gadgets weren't what made it hard to make a living in the music industry.... simple human greed did, the same type of human greed that has long sucked the soul of out of so many art forms in the pursuit of commercial success. If AI is trained on human knowledge, maybe it can acquire the same level of greed and soulessness, but in that case we are no worse off
So to be honest I don't see AI as any different. It will have some novel impact on the industry for sure... but I see it as just another tool in the toolbox. How best to utilize the technology will still be up to the creator.
Is there likely to be a lot of insufferably bad music created as a result of AI technology? HAVE.NO.DOUBT.YES.
But that doesn't mean it needs to get in the way of our own journey.
