This phrasing made me think of Baudrillard: https://en.wikipedia.org/wiki/Simulacra_and_Simulation , in particular "Simulacra are copies that depict things that either had no original, or that no longer have an original".
The AI produces something that is statistically similar to what it was asked for. A copy, through the weights, of some text selected from all the text it was trained on. A simulacra of good work.
