Would the same go for say, a great car? If it was created by a machine that was activated by a toddler pressing a button, would you value it less than if it was manually constructed by a team of men?
I think I would value the fruits of AI pretty highly if they were good - like if I was a coder I would probably value an AI for taking a lot of work off my hands, and value the code it produced just fine.
With art there is the question of originality. An example of ‘true art’ to my mind would be Dante’s writing, regardless of my valuing of it – it did, by conjuring up hell as we’ve known it since, construct a whole new world in mankinds imagination and changed peoples sense of morality and behavior, and at the same time raised the Italian language to a new level from which it became standardized. FJ’s posted image of the fisherman doesn’t attain to that level of reality-altering power, but then very little art does. I made a lot of film and music and drawing and writing that all could be called art by some definitions, but I would call very little of it art, myself. Most is just craft.
