Making an activity in which the primary limiting factors for most people are the time, knowledge, and effort required (as opposed to expensive tools) into an effortless slot machine pull is enfeebling to human creativity and agency. Who will spend the hours of making bad music to get to the point where they become good if they can just rely on something else to generate music that's "good enough"?

There's something to be said about all this which is related to AI generated images that I rarely see brought up: people with specific skills play roles within groups, so AI making their hobby that they dedicated so much time to more easily accessible makes them lose social value, which might make them quit altogether.

The common response that "people should make art because they love it, not for attention" is a prescriptive statement that supposes there are more or less "pure" forms of performing an activity and also ignores that art is a form of communication.

This does not augment the music making process in any way, it simply replaces it with what might as well be a gacha game. There's no low-level experimentation, no knowledge acquisition, no growth, and you can't even truly say you made whatever comes out.

It's not a tool for music creators, it's a tool for people who want slop that's "good enough".
