"The Robotic Moment"

In late November 2005, I took my daughter Rebecca, then fourteen, to the Darwin exhibition at the American Museum of Natural History in New York. From the moment you step into the museum and come face-to-face with a full-size dinosaur, you become part of a celebration of life on Earth, what Darwin called "endless forms most beautiful." Millions upon millions of now lifeless specimens represent nature's invention in every corner of the globe. There could be no better venue for documenting Darwin's life and thought and his theory of evolution by natural selection, the central truth that underpins contemporary biology. The exhibition aimed to please and, a bit defensively in these days of attacks on the theory of evolution, wanted to convince.

At the exhibit's entrance were two giant tortoises from the Galápagos Islands, the best-known inhabitants of the archipelago where Darwin did his most famous investigations. The museum had been advertising these tortoises as wonders, curiosities, and marvels. Here, among the plastic models at the museum, was the life that Darwin saw more than a century and a half ago. One tortoise was hidden from view; the other rested in its cage, utterly still. Rebecca inspected the visible tortoise thoughtfully for a while and then said matter-of-factly, "They could have used a robot." I was taken aback and asked what she meant. She said she thought it was a shame to bring the turtle all this way from its island home in the Pacific, when it was just going to sit there in the museum, motionless, doing nothing. Rebecca was both concerned for the imprisoned turtle and unmoved by its authenticity.

It was Thanksgiving weekend. The line was long, the crowd frozen in place. I began to talk with some of the other parents and children. My question — "Do you care that the turtle is alive?" — was a welcome diversion from the boredom of the wait. A ten-year-old girl told me that she would prefer a robot turtle because aliveness comes with aesthetic inconvenience: "Its water looks dirty. Gross." More usually, votes for the robots echoed my daughter's sentiment that in this setting, aliveness didn't seem worth the trouble. A twelve-year-old girl was adamant: "For what the turtles do, you didn't have to have the live ones." Her father looked at her, mystified: "But the point is that they are real. That's the whole point."

The Darwin exhibition put authenticity front and center: on display were the actual magnifying glass that Darwin used in his travels, the very notebook in which he wrote the famous sentences that first described his theory of evolution. Yet, in the children's reactions to the inert but alive Galápagos tortoise, the idea of the original had no place. What I heard in the museum reminded me of Rebecca's reaction as a seven-year-old during a boat ride in the postcard-blue Mediterranean. Already an expert in the world of simulated fish tanks, she saw something in the water, pointed to it excitedly, and said, "Look, Mommy, a jellyfish! It looks so realistic!" When I told this story to a vice president at the Disney Corporation, he said he was not surprised. When Animal Kingdom opened in Orlando, populated by "real" — that is, biological-animals, its first visitors complained that they were not as "realistic" as the animatronic creatures in other parts of Disneyworld. The robotic crocodiles slapped their tails and rolled their eyes-in sum, they displayed archetypal "crocodile" behavior. The biological crocodiles, like the Galápagos tortoises, pretty much kept to themselves.

I believe that in our culture of simulation, the notion of authenticity is for us what sex was for the Victorians — threat and obsession, taboo and fascination. I have lived with this idea for many years; yet, at the museum, I found the children's position strangely unsettling. For them, in this context, aliveness seemed to have no intrinsic value. Rather, it is useful only if needed for a specific purpose. Darwin's endless forms so beautiful were no longer sufficient unto themselves. I asked the children a further question: "If you put a robot instead of a living turtle in the exhibit, do you think people should be told that the turtle is not alive?" Not really, said many children. Data on aliveness can be shared on a "need-to-know basis" —for a purpose. But what are the purposes of living things?
