Antonio Relagado, senior editor for biomedicine for MIT Technology Review, isn’t too impressed with Elon Musk’s claims for Neuralink. In particular, he explains that the 8-10 year time line for the first available implants is absurd and impossible.
Let’s deal with Musk’s time line first. A brain implant is a medical device that requires neurosurgery. Proving that it works requires a stepwise series of experiments that each takes years, starting in rats or monkeys.
Here’s a time line from the real world: a company called NeuroPace was started in 1997 to develop an implant that controls epileptic seizures. It actually senses a seizure coming and zaps your brain to stop it. The device got approved in 2013—16 years later. And that was for a very serious medical condition in which brain surgery is common.
Putting an implant in healthy people? That would require extraordinary evidence of safety. And that’s hard to picture, because as soon as you open someone’s head you put that person’s life at risk. We at MIT Technology Review know of only one case of a healthy person getting a brain implant: a crazy stunt undertaken in Central America by a scientist trying to do research on himself. It caused life-threatening complications.
Musk doesn’t seem to be considering the ethical problems at all. It’s cool tech, but I wouldn’t let anyone stick wires in my brain unless it was to treat a serious medical problem with tested procedures.
So it’s not crazy to believe there could be some very interesting brain-computer interfaces in the future. But that future is not as close at hand as Musk would have you believe. One reason is that opening a person’s skull is not a trivial procedure. Another is that technology for safely recording from more than a hundred neurons at once—neural dust, neural lace, optical arrays that thread through your blood vessels—remains mostly at the blueprint stage.
So what facts am I missing? What makes it even remotely okay that Musk and Facebook are promising the public telepathy within a few short years?
We criticize religions for making false promises without evidence; we imprison people for bilking people out of money on false pretenses; so yes, I agree, why do we give billionaire industrialists a pass when they make secular claims that don’t stand a chance in hell of coming true, and when they do it on behalf of profit-making companies?
