Conducting an orchestra is an important role but the music is mostly a result of first of all the composer, and then the conductor / arranger's interpretation as well as the skill of the musicians. I really don't see the similarity to a human input of "GNU license, sad, jazzy." The resolution is just way too rough.
In fact, imagine comparing the experience of reading Snow Crash, to reading the sentence, "Cyberpunk story with sci fi elements, VR universe, pizza delivery guy with samurai sword."
