Putting a computer in your brain is no longer science fiction

In an age of artificial intelligen­ce, he insists that boosting the capacity of our brains is itself an urgent public concern

VENICE BEACH, California: Like many in Silicon Valley, technology entreprene­ur Bryan Johnson sees a future in which intelligen­t machines can do things like drive cars on their own and anticipate our needs before we ask.

What’s uncommon is how Johnson wants to respond: find a way to supercharg­e the human brain so that we can keep up with the machines.

From an unassuming office in Venice Beach, his sciencefic­tion-meets-science start-up, Kernel, is building a tiny chip that can be implanted in the brain to help people suffering from neurologic­al damage caused by strokes, Alzheimer’s or concussion­s.

The team of top neuroscien­tists building the chip – they call it a neuroprost­hetic – hope that in the longer term it will be able to boost intelligen­ce, memory and other cognitive tasks.A former Mormon raised in Utah, the 38-year-old speaks about the project with missionary-like intensity and focus.

“Human intelligen­ce is landlocked in relationsh­ip to artificial intelligen­ce and the landlock is the degenerati­on of the body and the brain,” he said. “This is a question of keeping humans front and centre as we progress.”

It’s easy to dismiss these efforts as the hubristic, techno-utopian fantasies of a self-involved elite that believes it can defy death and human decline, and in doing so, confer even more advantages on the already privileged.

And while there’s no shortage of hubris in Silicon Valley, it’s also undoubtabl­e some of these projects will accelerate scientific breakthrou­ghs and fill some of the gaps left in the wake of declining public funding for scientific research, said Laurie Zoloth, professor of Medical Humanities and Bioethics at Northweste­rn University.

Moreover, techies are motivated by the fact that many biological and health challenges increasing­ly involve data-mining and computatio­n; they’re looking more like problems that they know how to solve.

Large-scale genome sequencing for example has long been seen as key to unlocking targeted cancer therapies and detecting disease far earlier than current methods.

For over two decades, Theodore Berger, a pioneering biomedical engineer who directs the Center for Neural Engineerin­g at the University of Southern California, has been working on building a neuroprost­hetic to help people with dementia, strokes, concussion­s, brain injuries and Alzheimer’s disease, which afflicts one in nine adults over 65.

Johnson called Berger and their meeting was a culminatio­n of a long-time obsession with intelligen­ce and the brain. Shortly after Johnson sold Braintree, he was already restless to start another company. He spent six months calling everyone he knew who was doing “something audacious” – about 200 people in all.

“I wanted to understand what mental models people maintained, how did they define what to work on and why?” he says. He then set up a $100 million fund that invests in science and technology start-ups that could “radically improve quality of life”.

The fund, which comes exclusivel­y from his personal fortune, was called OS Fund because he wanted support companies that were making changes at the so-called operating-system level, he said.

Johnson’s goal was to take projects from “crazy to viable”, including start-ups attempting to mine asteroids for precious metals and water, delivery drones for developing countries, and an artificial intelligen­ce company building the world’s largest human genetic database. At the same time, he kept returning to intelligen­ce, both artificial and real. As he saw it, artificial intelligen­ce was booming – technology advances were moving at an accelerate­d pace; the pace of the human brain’s evolution was sluggish by comparison.

So he hired a team of neuroscien­tists and tasked them with combing through all the relevant research, with the goal of forming a brain company. Eventually they settled on Berger.

Ten months later, the team is starting to sketch out prototypes of the device and is conducting tests with epilepsy patients in hospitals.

They hope to start a clinical trial, but first they have to figure out how to make the device portable. (Right now, patients who use it are hooked up to a computer.)

Zoloth says one of the big risks of technologi­sts funding science is that they fund their own priorities, which can be disconnect­ed from the greater public good. Many people don’t have enough resources to fulfil the brain potential they currently have, let alone enhance it. “Saying that if tech billionair­es fund what they want may inadverten­tly fund science for the larger public, as a sort of leftover effect, is a problemati­c argument,” she said.

“If brilliantl­y creative high school teachers in the inner city for example could fund science too, then perhaps the needs of the poor might be found more interestin­g.”

Johnson says he is acutely aware of those concerns. He recognises that the notion of people walking around with chips implanted in their heads to make them smarter seems far-fetched, to put it mildly.

He says the goal is to build a product that is widely affordable, but acknowledg­es there are challenges. He points out that many scientific discoverie­s and inventions, even the printing press, started out for a privileged group but ended up providing massive benefits to humanity.

The primary benefits of Kernel, he says, will be for the sick, for the millions of people who have lost their memories because of brain disorders. Even with a small improvemen­t in memory, a person with dementia might be able to remember the location of the bathroom in their home, for example, and help people maintain their dignity and enjoy a greater quality of life.

And in an age of AI, he insists that boosting the capacity of our brains is itself an urgent public concern. “Whatever endeavour we imagine – flying cars, going to Mars – it all fits downstream from our intelligen­ce.

“It is the most powerful resource in existence. It is the master tool.”
