Ex Machina

Ex Machina (2015)

They say things happen in threes.

One, I watch a movie, Ex Machina, which poses provocative questions about how real an artificially intelligent human can be.

Two, I am in the middle of Neurosurgery research and come across some of the latest applications of Virtual Reality to navigate around the brain as if you were inside it.

Three, I get an email from my medical school about a new project in which students can practice difficult conversations with patients by speaking with virtual humans.

I like toys, but I do not consider myself a techie. Yet, I find myself fascinated by the concept of Virtual Reality. Why?

Then it hits me. I am trained in Theatre. Theatre is, by definition, Virtual Reality! You create a 3-D space with objects that look real but aren’t (as any actor who has had to eat cold mashed potatoes as if it were delicious ice-cream will tell you!). You surround yourself with people who are supposed to be real people  with whom you have real relationships. But of course, the whole thing is made up. The curtain will come down (the “console” will switch off). And just like that, Richard III becomes your cast mate and you go get a drink, no longer having to worry about being impaled on a sword (unless you gave a terrible performance . . .). And yet, your imaginary creation sent a room full of people home feeling new emotions and thinking new thoughts.

And so, the question becomes if the “Virtual Reality” of Theatre can provoke an emotional response, could the computerized Virtual Reality do the same, and perhaps even trigger the crucial emotion of empathy? That question must have occurred to journalist Nony Lapena when she teamed up with technologist Palmer Luckey to create a virtual world to portray the devastating reality of war-torn Syria

Her work was presented at this year’s Sundance Festival. So why does Ms. Lapena do it?

“Syria is so far away from most Americans. How do you attract a younger audience who might not pick up the newspaper to think about these important issues? That’s the point of all good journalism.”

All of which takes us back to the medical school project. Can interacting with virtual humans really help me prepare for such conversations with real patients? That depends, I imagine, on how “real” they are. And how do you know that? At what point does a computerized human cross that threshold? The movie Ex Machina proposed The Turing Test in which a human interacts with a machine that she is blinded to. If the responses of the machine convince the interrogator that she is speaking to a human, the machine has passed the test. In developing this test, Alan Turing raised an interesting point. The question, he said, is not can a machine think, but can it imitate human thought?

I have heard this line of reasoning used before in terms of empathy. Do we need to feel empathy to show it? Or is empathy a skill, a craft that should be learned like any other part of the physician’s arsenal?

The neurosurgeon uses Virtual Reality to master the architecture of the brain, through relentless repetition and adjustment. Can empathy be achieved in the same way? Is it trainable?

And, ultimately, when the headset is removed, the electronics shut down, and I am sitting in front of a patient with all our histories, biases and experiences present, but invisible and we begin to talk, into what reality have we just entered?

Have an existential weekend!
