New form of transcendence: uploading the brain to the cloud

So yeah. Nectome is a preserve-your-brain-and-upload-it company. Its chemical solution can keep a body intact for hundreds of years, maybe thousands, as a statue of frozen glass.

The idea is that someday in the future scientists will scan your bricked brain and turn it into a computer simulation. That way, someone a lot like you, though not exactly you, will smell the flowers again in a data server somewhere.

This story has a grisly twist, though. For Nectome’s procedure to work, it’s essential that the brain be fresh. The company says its plan is to connect people with terminal illnesses to a heart-lung machine in order to pump its mix of scientific embalming chemicals into the big carotid arteries in their necks while they are still alive (though under general anesthesia).

The company has consulted with lawyers familiar with California’s two-year-old End of Life Option Act, which permits doctor-assisted suicide for terminal patients, and believes its service will be legal. The product is “100% fatal,” says McIntyre. “That is why we are uniquely situated among the Y Combinator companies.”

Brain uploading will be familiar to readers of Ray Kurzweil’s books or other futurist literature. You may already be convinced that immortality as a computer program is definitely going to be a thing. Or you may think transhumanism, the umbrella term for such ideas, is just high-tech religion preying on people’s fear of death.

Either way, you should pay attention to Nectome. The company has won a large federal grant and is collaborating with Edward Boyden, a top neuroscientist at MIT, and its technique just claimed an $80,000 science prize for preserving a pig’s brain so well that every synapse inside it could be seen with an electron microscope.

McIntyre, a computer scientist, and his cofounder Michael McCanna have been following the tech entrepreneur’s handbook with ghoulish alacrity. “The user experience will be identical to physician-assisted suicide,” he says. “Product-market fit is people believing that it works.”

Nectome’s storage service is not yet for sale and may not be for several years. Also still lacking is evidence that memories can be found in dead tissue. But the company has found a way to test the market.

Following the example of electric-vehicle maker Tesla, it is sizing up demand by inviting prospective customers to join a waiting list for a deposit of $10,000, fully refundable if you change your mind.

So far, 25 people have done so. One of them is Sam Altman, a 32-year-old investor who is one of the creators of the Y Combinator program. Altman tells MIT Technology Review he’s pretty sure minds will be digitized in his lifetime. “I assume my brain will be uploaded to the cloud,” he says.

The brain storage business is not new. In Arizona, the Alcor Life Extension Foundation holds more than 150 bodies and heads in liquid nitrogen, including those of baseball great Ted Williams. But there’s dispute over whether such cryonic techniques damage the brain, perhaps beyond repair.

So starting several years ago, McIntyre, then working with cryobiologist Greg Fahy at a company named 21st Century Medicine, developed a different method, which combines embalming with cryonics. It proved effective at preserving an entire brain to the nanometer level, including the connectome—the web of synapses that connect neurons.

A connectome map could be the basis for re-creating a particular person’s consciousness, believes Ken Hayworth, a neuroscientist who is president of the Brain Preservation Foundation—the organization that recognized McIntyre and Fahy’s work with the prize for preserving the pig brain.

There’s no expectation here that the preserved tissue can be actually brought back to life, as is the hope with Alcor-style cryonics. Instead, the idea is to retrieve information that’s present in the brain’s anatomical layout and molecular details.

“If the brain is dead, it’s like your computer is off, but that doesn’t mean the information isn’t there,” says Hayworth. A brain connectome is inconceivably complex; a single nerve can connect to 8,000 others, and the brain contains millions of cells. Today, imaging the connections in even a square millimeter of mouse brain is an overwhelming task.

“But it may be possible in 100 years,” says Hayworth. “Speaking personally, if I were a facing a terminal illness I would likely choose euthanasia by [this method].”
