Also, I don't think there is any example testing the conclusion. There is no case to point at that any of the factors they listed are sufficient to convey authorship. Would love to be pointed to a case where rejecting decisions and redirecting to a different approach was deemed human authorship. What we do know is that you can disclaim the part of the code a human didn't author. In fact, the Copyright Office requires you disclose and disclaim. If anyone out there has more factual and citable sources please share.
