For the specific process that generated this story, I think a generous comparison could be made to something like photography. Yes, the machine is producing the resulting work, but under the guidance and curation of an artist that sets an appropriate parameters and context to the machine. I’d submit that this can result in varying levels of authorship, much like the difference between a snapshot (one-shot?) and a carefully controlled studio photograph, depending on the depth of preparation, iteration, and curation the photographer performs.
