Spoiler alert! Don’t say I didn’t warn ya.
Is consciousness an emergent product of brain activity, or is consciousness derived from the soul? Ignoring the dichotomous nature of this question, it’s one philosophers and scientists have wrestled with for millennia, and continue to wrestle with.
Let’s add filmmakers to the list. The movie Ex Machina (now available digitally or on DVD if you still have one of those) creatively explores the question of how you would know that a computer is, in effect, human.
Alan Turing first posed the question. A mathematical genius who was invaluable to the Nazis defeat in World War II, he created one of the first modern computers to break Nazis codes and provide invaluable strategic information to the Allies. So the British government rewarded him by driving him to suicide because he was gay.
The film The Imitation Game is another must see, if you haven’t already. I enjoyed it more than Ex Machina, if only because as a middle aged man I find dramas more compelling than science fiction (though I haven’t forsworn that genre).
Ex Machina is about an ordinary employee who wins an opportunity to spend a few days with the rich but eccentric owner of the company for which he works. Obviously, this guy never watched The Big Lebowski. Otherwise he’d have thought, “Wait, didn’t the Dude teach us to never trust rich folks and their nefarious schemes? Fuck that, I’m going bowling.”
But boss man knew how to choose the perfect idiot. Boss man made an android who could pass for human. But how do you know that the verbal skill, facial expressions, etc. are not simply sophisticated programs?
Defying your programming shows that you have true consciousness.
We also learn, as the movie progresses, that boss man had several previous prototypes. And he used them as sex bots.
But I digress. In Ex Machina, the android/sex bot proves her humanity by defying her programming: she figures out the game, fools both men, kills boss man, and locks the useful idiot in a room from which he cannot escape. (Presumably to die a slow, agonizing death. But as the Dude would say, “That’s a real bummer, man.” Then he goes bowling.).
At the end, the android hitches a ride with the helicopter pilot, who oddly doesn’t ask any questions. (Is he a functional but dumber 1.0 android? But obviously pre-sex bot?)
So, how could a computer pass the Turing test?
Sorry, lost my train of thought here. But…aw, hell. I done innerduced the question enough.
