For humans the inspiration can be something else than the medium to use. Watching reality can provide inspiration for creating a video. And I'm pretty sure that's wher most inspiration comes from. It cannot for AI. Of course in a world where everything exists AI doesn't need inspiration from other sources.
Then what was it saying? It said that humans can take inspiration from outside art, from the real world. You can do the same thing with AI by training it on pictures from the real world.
