And why should it matter? How about judging a story on its merits?
Why would I pay you for the work of a robot? Also, this is art we are talking about. The robot is only stealing the work product of millions of other people and regurgitating it into a story. Same thing with the AI that produces images, though more noticeable: it outright steals paintings and styles and regurgitates them based on its algo. In many cases it 90-99% successfully reproduces the style of an artist, albeit with some flaws that only artists would notice (and an abundance of screwed up fingers).
The artist in question—usually some hobbyist on some art website somewhere—is made obsolete in seconds by an AI that stole his work, and for which he will never be compensated for.
This is not the way we should treat art or artists.
