I do not approve of the use of the term “creator” here when they may believe they are creating but they are actually working inside a box (machine) or job parameter which inherently is derivative.
As in, I can whistle a song I created on the guitar because I pull it out of thin air - can he do the same with his “creation” as it were?
Let's not gate keep the word "creator". Writing new software is just as much "creating" as whistling a tune, writing a song, drawing a new piece of art, painting a miniature, carving a stone, or anything else. Something exists now that didn't exist before. It has been created.
It's unclear to me precisely what your definition of creator is, but it seems like one nobody else shares. It has to be something made without constraints? Or something that can be effortlessly reproduced later? Or something that is 100% non-derivative?
Do you really believe the songs you write on the guitar are non derivative?

Stay in your lane.
