Elon Musk’s start-up, Neuralink, has implanted a smart chip in the brain of a guinea pig pig, a prototype to make the version for humans that will restore speech and mobility to paralyzed people.
«It’s like a Fitbit (smartwatch) in your skullElon Musk enthused Friday at an online conference on the progress of his brain-to-computer interface project, which is arousing much skepticism in the scientific community.
The futuristic entrepreneur (Tesla, SpaceX) presented a year ago a chip with ultra-fine threads, which can be implanted in the brain by a robot – a kind of ultra-precise sewing machine. The new model, wireless thanks to bluetooth technology, charges at night and measures 23 mm in diameter (like a small coin) by 8 mm in thickness.
Treat diseases
In theory, the round chip will be implanted in the brain, without having to spend a night in the hospital, and without leaving any trace, except for a small scar under the hair.
It will first be used to treat neurological diseases. But the long-term goal is to make implants so safe, reliable and simple that they would qualify for elective (comfort) surgery. People could then spend a few thousand dollars to equip their brains with computing power.
For now, in Neuralink’s labs, the pig Gertrude is walking on a treadmill, snouting in a feeder hanging in front of her, while the chip retransmits her neurological signals. From this information, the computer is able to predict at any time where each of its members are. What gives hope to restore mobility to paraplegic people.
“Regain full use of the body”
In the event of a spinal cord injury, we could implant another chip at the site of the injury, and bypass the “transmission circuitsDamaged, imagines Elon Musk. “In the long term, I am sure that we will be able to regain full use of our body».
Many companies are working on thought control of computers, and more brain-machine interfaces are in development. Facebook is funding a project to translate brain activity into words, via algorithms, in order to give voice to people who have been silenced due to neurodegenerative diseases.
Many scientists point out, however, that the brain is not as compartmentalized as one would like to think. “Each brain has a unique, massively interconnected structure», Commented Dean Burnett, researcher at Cardiff University, ahead of the conference, saying he was skeptical of the real advances of Neuralink.
The goal of the whimsical boss, with this presentation on YouTube, was above all to attract and recruit many engineers, surgeons, chemists, robotics specialists and others. The start-up has only a hundred employees, but hopes 10,000 as soon as possible, to meet a mountain of challenges.
Inviolable communications
The computer chip must be protected against external disturbances (interference on the waves, signal strength) but also internal. Its communications with the smartphone and any other machine must be inviolable.
And of course, as with Tesla’s self-driving cars, behind the boss’s ambitious announcements, the chip relies on regulators’ green lights. Elon Musk announced that Neuralink had just obtained approval from US health authorities for tests, without specifying a horizon for the first human implantations.
In July 2019, he promised them for 2020. But nothing dampens the ardor of the billionaire, who wants to colonize Mars and fears that artificial intelligence (AI) technologies will turn humans into “domestic cats” of computers. The chip is thus supposed to allow us to arrive at a “symbiosis with AI».
He also mentioned the possibility of communicating raw thoughts, not limited by human languages - of the “Consensual and conceptual non-linguistic telepathy».
Save memories
His team dreams, among other things, of putting an end to extreme pain, of curing depressions and addictions or of unraveling the mysteries of consciousness.
Referring to an episode of the Black Mirror series, which connects nightmarish scenarios where humans are overwhelmed by technology, Elon Musk also said that it would be possible to store his memories in digital form.
«You will be able to save your memories, and also potentially download them in another body or in a robot“, he said. “The future is gonna be weird».
