>Me labeling "authentic" it or not should not affect it's artistic value.
The problem with automated imitation generators is that they can produce thousands of painting that imitate Van Gogh, but does not have the same soul.
It is the same reason why these things cannot create genuinely funny jokes. They cannot assess the funnyness of the themselves. They cannot feel, and cannot do the filtering based on emotion.
It is easy to recognize the emptiness of a joke, but not so easy for a painting, or some other form of art.
This is why it will never work for art. But the sad thing is that that will not stop them from being used to create art. Because it just needs to sell.
I would say that for art, at least for most of the movies, music etc, this was already the case. So nothing much to lose.
