I think there's difference between synthesizers, which I would compare to something like different paints and brushes and papers, and then Photoshop and Corel draw and whatnot; and where image generators are heading which is more analogous to automatic music generation.

I will also put it forward that for reasons I'm ignorant of, eye seems to be more readily fooled than ear. 20 years ago with crappy tools all I had to do was smudge and clone a hydrant in a photo and it would effectively be gone for 99% of observers. But similarly primitive ways of trying to change or later a sound file were immediatelly noticed by all listeners.
