I don’t understand you. The amount of human art, or indeed the possible maximum number possible of human artistic expressions (from the beginning of time until the end of the universe), is, I believe, far smaller than the pictures you would have left after your sorting filter.
I don't know what you mean by a 'sorting filter', but what I'm talking about is an algorithm that takes >40Mb of data as input (pictures of Bolt and Athens for example) and uses this data to output ~40Mb of Bolt in Athens.
I mean human artists to be an analogy: humans can 'select' a picture of Athens Bolt without enumerating all others. I don't see why computers couldn't.
