this is just gonna be my current thought on it, and its defo full of holes that I fall in all the time with my own stuff... but ultimately I feel if you don't understand how a tool, like AI, came up with the thing its done, it is not really 'yours'. So, if I got real smart and created an AI model that created music that I like, sure, that is mine. If I trained that AI on only Nine Inch Nails, then I think I might start having issues... If I use an AI model that I didn't make, and all I did was put a prompt in, I don't think I have any ownership of that, beyond a curiosity... But then.. If I started sampling that and creating my own work from that, then it becomes more an expression of myself again...
That's similar to how I feel about sampling, and how I feel about tools that write and suggest chord progressions, or even (the thing I use all the time) slicers and glitch plugins..
It has all these open questions, and I use ownership in both the 'I actually own the output of this so I'm free to share it' and the 'I can feel proud of the content I've made' way.
Ultimately, I do like the use of AI for prompting new creative acts. I ran a tabletop campaign recently, and in my depth of feeling uninspired, bashing "I need 20 missions for a pirate themed tabletop skirmish game" gave me no usable ideas, but I did get 8-10 things I could jump off of and use..
So yeah.. it is a biiig mess.. I don't think I'll use AI for music for a while, as I'm not a programmer, I don't know if I could ever make my own AI model, so I wouldn't feel like its 'mine', for whatever that is really worth. I can't wait to hear what people actually do with it creatively though!
