The Science of Self/Less

When business tycoon Damien Hale (played by Ben Kingsley) faces death from cancer in Self/Less, in theaters today, he doesn’t go gently into that good night. Instead, he undergoes a radical underground medical procedure called “shedding” that allows him to transfer his mind into another, younger, healthier, lab-grown body (Ryan Reynolds’s body, to be exact) and start a whole new life with a new identity.

For now, this is science fiction—but, says Charles Higgins, a neuroscientist at the University of Arizona, it could one day happen. “We cannot yet conceive of a machine that could scan the brain to the extent required to do what is in the movie,” he tells mental_floss. “But 100 years ago we could not conceive that in our pockets we would carry what are, essentially, supercomputers and communicators that we can talk to anyone on the planet with.”

Studying the brain is Higgins's business. “I’m interested in the interface between the mind and the brain and quantifying things that are normally unquantifiable, like depression, mood, consciousness, and self,” he says. Among the things he and his team are working on in his lab: grabbing electrical signals from insect brains to build high-tech robots with excellent vision; figuring out how cognition works by creating a simulated, computerized rat that wanders around a digital maze; and gathering data on human sleep with a device he built. So though he didn’t consult on Self/Less during production—the studio brought him on afterward—he’s an excellent source to talk to about the film’s science.

According to Higgins, there are huge hurdles to jump before we transfer consciousness from one body to another. For one, there’s a lot we don’t understand about how the brain—and consciousness in particular—work. “If you ask 100 different experts to list what the brain does, you’ll get 100 different answers,” Higgins says. “The brain definitely regulates your life support. Sometimes we use the word cognition—is that what the brain does? It’s a memory system as well. You could go on and on.”

Once we understand the brain in the same way we understand the heart or a computer, Higgins says, “we’ll be able to see how brains are related and understand what the important details we need to get out of the brain are.”

Another challenge: Computers have software, but the brain isn’t quite so simple. “The software and the hardware are all [together],” Higgins says. “So what details of the brain structure do I need to read out?”

Some people, he says, think we need to go down to a quantum level. Others think it might be unnecessary to go subatomic to scan consciousness: “You could go just to the level of of neurons and other connections,” Higgins says. “But we don’t really know.”

Even if we did know where consciousness was found, we don’t have the technology to transfer it. In Self/Less, the company Phoenix Biogenic uses what looks like a souped-up fMRI (functional magnetic resonance imaging) to access and transfer consciousness from one body to another. Higgins says this is “the right idea, although at this point fMRI technology does not allow us to get down to sub-neuron resolution.”

And then there are the thorny ethical issues. When Hale discovers that he hasn’t been given a lab-grown body after all, but the body of a man who once had a life of his own, he’s disgusted and outraged and not entirely sure what to do.

“Scanning somebody’s brain and putting it into another body—you have to wonder, did you destroy someone’s self to do that?” Higgins says. “Let’s say you cloned me and grew me until I was 20 years of age, and then you transferred [my consciousness] into my new, younger body. Was the 20-year-old clone a person of its own? Did it have a self, a soul, an inherent value of its own? Did I kill someone?”

Uploading a consciousness to a computer will likely come first, “because the ethical issues are almost nonexistent,” he continues. “Scanning something into a computer isn’t going to hurt anybody.”

Of course, whether you’re talking about computerized consciousness or body hopping, it’s all hypothetical for the moment. But if and when we do get there, there’s more could do more than merely swap older bodies for younger models. Higgins foresees a future where we can talk to computer copies of the greatest scientists who ever lived, or instantly upload to our brains an education that would otherwise take 10 years to complete.

“If you could actually do this, what impact would it have on society?” he asks. “What if everybody understood world history? Could American citizens be better informed—make better decisions, work together, support our congress and our president rather than having a bunch of different uninformed opinions? What if everyone was an expert engineer and knew how to work their newfangled TV sets? Life would be different. Would it be more pleasant? Maybe you’d spend less time being frustrated by politics and electronics and anything else you’d want to learn about. Or maybe it would create an even worse have and have not situation. It’s a very difficult thing to say.”

We may be very, very far from the future as imagined by Self/Less, but that doesn’t mean we’ll stop looking for it. Humans have been searching for immortality for as long as we’ve been around. “We’ve all felt that when somebody died that something was lost, either just to us or to the world,” Higgins says. “That’s been around as long as humankind, and I don’t see that going away. That will drive technological development for however long it takes until this is possible.”

The Time Douglas Adams Met Jim Henson
Original image

On September 13, 1983, Jim Henson and The Hitchhiker's Guide to the Galaxy author Douglas Adams had dinner for the first time. Henson, who was born on this day in 1936, noted the event in his "Red Book" journal, in characteristic short-form style: "Dinner with Douglas Adams – 1st met." Over the next few years the men discussed how they might work together—they shared interests in technology, entertainment, and education, and ended up collaborating on several projects (including a Labyrinth video game). They also came up with the idea for a "Muppet Institute of Technology" project, a computer literacy TV special that was never produced. Henson historians described the project as follows:

Adams had been working with the Henson team that year on the Muppet Institute of Technology project. Collaborating with Digital Productions (the computer animation people), Chris Cerf, Jon Stone, Joe Bailey, Mark Salzman and Douglas Adams, Jim’s goal was to raise awareness about the potential for personal computer use and dispel fears about their complexity. In a one-hour television special, the familiar Muppets would (according to the pitch material), “spark the public’s interest in computing,” in an entertaining fashion, highlighting all sorts of hardware and software being used in special effects, digital animation, and robotics. Viewers would get a tour of the fictional institute – a series of computer-generated rooms manipulated by the dean, Dr. Bunsen Honeydew, and stumble on various characters taking advantage of computers’ capabilities. Fozzie, for example, would be hard at work in the “Department of Artificial Stupidity,” proving that computers are only as funny as the bears that program them. Hinting at what would come in The Jim Henson Hour, viewers, “…might even see Jim Henson himself using an input device called a ‘Waldo’ to manipulate a digitally-controlled puppet.”

While the show was never produced, the development process gave Jim and Douglas Adams a chance to get to know each other and explore a shared passion. It seems fitting that when production started on the 2005 film of Adams’s classic Hitchhiker’s Guide, Jim Henson’s Creature Shop would create animatronic creatures like the slovenly Vogons, the Babel Fish, and Marvin the robot, perhaps a relative of the robot designed by Michael Frith for the MIT project.

You can read a bit on the project more from Muppet Wiki, largely based on the same article.
