Fifty-two prominent researchers on intelligence, agreed to a broad definition of the term, “Intelligence:”
“Intelligence is a very general capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not merely book learning, a narrow academic skill, or test‑taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings—‘catching on’, ‘making sense’ of things, or ‘figuring out’ what to do. Intelligence, so defined, can be measured, and intelligence tests measure it well”
–Gottfredson, L. S. Mainstream science on intelligence: excerpt from an editorial with 52 signatories, history, and bibliography. Intelligence 24, 13–23 (1997).
Intelligence of the artificial variety, if it is ever to be considered on a par with the human variety, should then include each of these abilities, as well as the capabilities for comprehension, “catching on,” etc. A recent film about this very subject has captured some very important aspects of concern, supposing that there is some sort of breakthrough eventually that creates what might be described as a “conscious machine.”
“Ex Machina,” the 2015 Universal Studio film, directed by Alex Garland, starring Domhnall Gleeson, Alicia Vikander, and Oscar Isaac, tells the story of a reclusive billionaire genius who owns the largest search engine company in the world, who has built a research facility in a remote mountain setting for the purpose of building an artificially intelligent robot, with the expressed goal of passing the well-known “Turing Test,” for determining if the “machine” is self-aware. As the film opens, Caleb, an employee of the high-tech firm, has won a lottery drawing within the company to visit the CEO, Nathan, at his research station and, as a result, has the opportunity to test the A.I. to see if it is truly “self-aware.” If Nathan has succeeded, he claims that it would be “the most important event in the history of man.” Domhnall Gleeson’s character corrects him by describing it as “the most important event in the history of gods.”
We are immediately thrown into the astonishing world of the newly “born” A.I., Ava, and by virtue of the design of a special high-tech suit, Alicia Vikander’s character appears to be constructed of wires and metal bones, illuminated by a variety of internal lights, and covered strategically by patches of flesh-like “skin,” allowing for the display of facial movements, and to give “Ava,” a basic human appearance. The internal workings are visible enough to suggest how the robot functions, while still providing the basic contours of the human form. It is an accomplished display of special effects which are both astonishingly realistic and profoundly disturbing at the same time. The contrast is designed to be unsettling to the moviegoer—to draw us in and to shock us into believing that it could be accomplished.
If you haven’t seen the film, it is a powerfully compelling story, and I recommend it wholeheartedly as a morality tale, which begs the question of how we would have to treat such entities should they actually qualify as being self-aware, as well as a serious warning about what might happen if we don’t get it right. The character of the robot’s creator, Nathan, clearly isn’t sufficiently cautious regarding the implications of bringing a self-aware robot “online,” and he seems callous and narcissistic as an eccentric billionaire genius.
Story elements aside, many of which were designed to create drama and provide tension, the underlying implications of the circumstances surrounding such an endeavor gave me pause to consider why any future human being capable of such a feat would even want to dabble in such an undertaking in the first place. Regardless of the level of extraordinary intelligence required, bringing such an entity into existence would also require just the right balance of human decency, compassion, and empathy, coupled with profound and penetrating neuroscientific acumen. While the technological and scientific principles supporting such an invention would be of great interest to artificial intelligence advocates generally, and those who would stand to benefit financially and otherwise would have an understandable motive to see it through, the actual created entity itself would present humanity with the most challenging and perplexing dilemma it could ever face—how to know if it would turn out to be a powerfully beneficial scientific breakthrough, or the eventual instrument of our own obsolescence!
At this point in human evolution, the possibility of constructing anything even close to the self-aware robot we meet in the film seems, on the face of it, to be a very unlikely development for a number of reasons. Throughout the film, we are presented with brief glimpses of the architecture and underlying technologies which provide the foundation for how such an entity might be constructed and assembled to achieve the desired result of the project, and none of those elements exist currently in any form even resembling in the slightest degree that which would be necessary for accomplishing this enormously complex task. Using even the most sophisticated and powerful computers known to humanity, we can barely reach a level of AI that even just approximates the sophistication of the most basic nervous system of the most minimally sentient creature.
Several projects being undertaken to “mimic” the human brain, using our most promising approaches for “deep learning,” and the giant “supercomputers” like IBM’s Watson, are simply nowhere near being able to reproduce anything resembling even a fraction of the innate capabilities that our own three pound squishy mental organ can manage, with its trillions of connections inside our exquisitely shaped and evolutionarily designed skulls. This inheritance of the long evolutionary path of modern primates provided Homo sapiens with a distinctly and uniquely capable cognitive system, which exists (so far as we know) only within human beings, and consists of the most complex arrangement of neural networks of any known species. It is presumptuous indeed to suppose that any artificial system might one day exist, which could recreate precisely, that which now exists within us, possessing the same character and quality of a living, breathing, sentient modern human.
Even the tiniest quantum “neurons,” represented by the atomic scale of the components proposed by the advent of quantum computers, require supporting technologies that would seriously prohibit squeezing them into a space as small as the human skull. The character of Ava, portrayed unflinchingly in the film by Alicia Vikander, has so many affectations of modern humans, and is intriguing beyond any expectation of her creator or her Turing tester, that we easily get caught up in suspending our knowledge that no such creature currently exists. The interplay between Caleb and Ava reaches a fever pitch eventually, and we are compelled to hang on to the edge of our seats as the drama unfolds.
It is well worth the investment of the resources available to produce sophisticated and intelligent machines, and I’m not suggesting that we abandon artificial intelligence research and development. Many of the films which attempt to portray what might take place in a world where such inventions exist, often only offer a superficial portrayal of the opposing characters, glossing over the significant differences between artificial machines and sentient living humans. In the film, “Ex Machina,” the contrast is absolutely startling, as both human and machine present a potent display of the limits of both the technology and our human understanding of what makes us truly self-aware.
What it usually boils down to is whether or not the film makers believe consciousness is a product of brain physiology—whether it “emerges” out of the firing of neurons and the electrochemical processes defined by neuroscience, or instead exists as a phenomenon of indeterminate origin which is made available to us by virtue of possessing “the right stuff,” –a sufficiently complex cognitive organ.
Any attempt to reduce the complexity and holistic phenomenal experience of consciousness to simply putting together enough neurons in the right arrangement and coordinating systems and functions in just the right manner, seriously underestimates not only the phenomenon itself, but fails to take into account the awesome and sometimes mysterious character of our humanity. Human nature and nurture won’t ever be truly obsolete, as long as we continue to appreciate the supreme value of human life, and acknowledge with gratitude, our awareness of our subjective experience of existing as complex sentient beings. We are imperfect creatures who often don’t understand or appreciate fully how miraculous it is to be a participant in the experience of life on Earth, and we cannot expect any artificial “life” to be anything other than a reflection of the moral character and scientific competence of its creator.
