It all depends on what you define as creative, and there are two ways of thinking, that being creative is a characteristic intrinsic of life matter this being the least interesting path since it means that how much we wanted to a computer will be bound by the rules imposed by our programming thus never being truly creative but forcefully creative.

The other variant is the more fun one since the act of being creative is observed by creating pieces of literature, music or science; giving a robot the instruction on following patterns to create these kinds of authorship means the robot has the capacity to be creative and thus all the ramification that you just exposed in your article.

Thank you for posting this, it was thought-provoking for me.
