absorb the energy and start to glow. The scanner will record the positions of the glowing dots attached to the cells, and their patterns will give us a detailed map of all the connections within the brain and the strength of those connections.”
    His voice is getting louder. That often happens when Dad talks about his research. He can’t help it; he gets excited. “This is the key,” he says, holding the vial of nanoprobes up to the light. “All our memories, all our emotions, all our quirks and virtues and flaws—all that information is stored in the connections between our brain cells, which create new links or alter the old ones whenever we learn or remember something. So if we make a sufficiently detailed scan of a person’s brain, we’ll have a full description of his or her personality, which can be held in an electronic file of about a billion gigabytes. The next step is downloading that information into circuits that mimic the cells of the human brain. We already have that kind of neuromorphic circuitry because we built it to hold our AI software.”
    The audience is murmuring again. Some people are confused. And some, like me, are terrified, because they can see where this is going. Shannon Gibbs leans forward and points at the screen. “Are you talking about making copies?” she asks. “Copies of our brains?”
    â€œYes, exactly. Once the information is downloaded into the neuromorphic electronics, the circuits will replicate the connections of the person’s brain, re-creating all its memories. And as data flows through the circuits, the electronic brain will generate new thoughts based on these memories. Just like in a human brain, the thoughts will organize themselves into a conscious intelligence, a self-aware entity that can set goals for itself and communicate with others, either by text or through a speech synthesizer. And the ‘personality’ of this new intelligence would be identical to the one inside the person’s head, because it would be based on the same memories and emotions and character traits.”
    Shannon wrinkles her nose. She looks queasy. “Have you…tried doing this yet? Making a copy of someone?”
    Dad nods. “Four months ago we tried the procedure on three volunteers. All were Army veterans with high IQs. Unfortunately, the experiment failed each time. We scanned their brains and successfully downloaded the data into the circuits, but in each case the human intelligence failed to run on the computer. We were able to copy their minds, but the copies didn’t survive the transfer.” He furrows his brow. “Since then we’ve studied the problem, and now we know what went wrong. The crucial factor is the person’s age. After the age of eighteen, there’s a change in the structure of brain cells. They become coated with greater amounts of a substance called myelin, which insulates the cells and makes them more rigid. This increases the efficiency of a person’s thinking but reduces its flexibility. The mind of an adult is simply too inflexible. It can’t adapt to the new conditions of residing in a machine.”
    â€œSo now you’re going to try to copy younger minds?”
    He nods again. “We were planning to conduct the next phase of the experiment later this year, but the events in Russia have accelerated our plans. This time, all the volunteers must be sixteen or seventeen. At that age you’ve reached your maximum brainpower but your minds are still adaptable. In addition to being highly intelligent, the volunteers must have strong, resilient personalities.” Dad sweeps his arm in a wide arc, gesturing at all the teenagers in the room. “All of you meet those requirements.”
    Shannon rears back in her seat as if she’s been slapped. “And where are you going to store the copies of our brains?” Her voice is furious. “In a supercomputer? A
