You're the second person I've replied to about that, but they give only two examples of image generation which were denied for claiming to contain absolutely no human authorship which can be considered subjective by the courts as digital camera output is copyrightable based on who presses the button, the office admits they are waiting for public input (the legislative body) on the matter, and also since this is the copyright office it has no bearing on other types of established property such as license or patent law.

Until the laws clarify I say treat AI code as radioactive.
