we would laugh at the idea that random computer output is communicating something just because someone put it in a legible font
but that's all AI-generated artwork is: a (procedurally-generated, somewhat) legible font for visual concepts
the entire novelty of it is simply that it produces an image that you can read
being able to use computers to produce legible images is indeed a potentially profound development in our toolset for artistry but it is not in itself a form of communication
