As much as the media likes to try and romanticize the discipline, machine learning is not going to produce skynet, Durandal, Leela, or Shodan any time soon. (and certainly not by accident).
More realistically, the kind of machine learning that this represents, will further demonstrate the fallacy of considering original works original. (All works created by human hands, are likewise reflections of previous works or experiences that the human in question has encountered, and then processed into 'new' media-- that is to say-- all works are derivative works.) Since the legal system has already clearly taken the position that AI cannot hold copyrights, (and thus the derivative works produced by AI cannot have copyright ascribed to the AI--- the matter of ascribing the creator of the AI, or the operator of the AI, that copyright is still up in the air) there is an opening for this kind of revelation to continue to eat away at the notion of intellectual property as a whole, which I am excited for.
However, this machine learning exercise really is just boiling down the process of image creation based on keywords, down to a fixed subset of mathematical expressions and iterative processes. It is the exact opposite of the romatic notions the press ascribes to AI--- It is the active removal of the 'magic' from the creative process, through demonstrating that the 'creative process' is purely mechanistic.
Eventually, it MIGHT end up that what we consider "consciousness" (and I use that word very broadly, as it means different things to different people) is indeed a wholly mechanistic process itself, thus eliminating all conceptions of "human uniqueness" (and thus the "magic" of free will, independent thought, and creativity as a whole), or "human exceptionalism".
That day is a long way away however.
Society would have a number of very difficult questions to ask itself if human behavior is a wholly mechanistic process. Much like you dont ascribe blame to a food disposal when it eats a person's fingers when they reach inside with it turned on, a "Humans are mechanisms, and we can prove it" world would have a greatly difficult time with such simple things as ascribing guild, blame, or fault via a legal system-- as any outcome could be ascribed to a set of pre-existing conditions prior to the event being put on trail. "Choice" would not be a thing that makes sense, and thus, neither would "blame".
It is my personal conjecture, that should the reality of "Humans are mechanisms, and we can prove it" come to pass, what will happen is just that humans will continue to insist that they are magical and special, with "souls" and thus "free will" is not an illusion, etc.
