I'd welcome you to offer a rigorous definition of this supposedly well-known distinction. Computers don't generate anything spontaneously. They always require some level of direction.
Are the outputs of VSTs not "computer generated"? You can fumble around on a keyboard just moving up and down until you find the pitch you want, and the software will output an orchestral swell of dozens of instruments that take years and years to master, with none of that effort expended by the one mashing the keyboard.
Is that sound computer-assisted or computer-generated in your estimation? Much the same with AI images. It's not fundamentally different from any other computerized tool.
