Just over a year since their last major announcement, Elon Musk’s Neuralink is finally ready to show off the fruits of its labor: a revolutionary brain-machine interface that could blur the lines between humanity and technology, as well as give our feeble fleshy minds a leg up against increasingly capable AIs.
Musk took to the stage at the Neuralink headquarters on Friday afternoon to reveal a working “V2” prototype of the automated surgical system that the company debuted last year. This machine will “sew” as many as 1,024 impossibly thin 5 micron-wide electrodes into a person’s brain.
So far the system only taps into the brain’s cortical surface but the company hopes to eventually insert them deeper into the grey matter to monitor deeper brain functions (ie the hypothalamus).
These electrodes will connect to Neuralink’s “Link 0.9” chip, a 23mm x 8mm sealed unit which plugs into a small hole bored into the patient’s skull and collects the signals that the electrodes pick up. The Link will measure the patient’s temperature, pressure and movement, potentially providing early warnings about imminent heart attacks or stroke, Musk said.
The Link will fit flush in the skull and transmit data wirelessly at megabit speeds up to 10 meters. It will also reportedly offer inductive charging and a full day’s battery life, enabling users to recharge it as they sleep.
The small pod worn behind the ear that the company showed last summer has since been removed in favor of the all-in-one design we see today. The entire installation process will reportedly take a little under an hour to complete. “It’s like a Fitbit in your skull,” Musk noted during the event.
During the live demonstration, Musk introduced the crowd to a trio of pigs: Joyce, Gertrude and Dorothy. Joyce has not had the implantation surgery and appeared to be a perfectly happy and healthy pig.
Dorothy had the surgery but had the implant subsequently removed to illustrate that the Link device is not a permanent attachment but rather can be installed and removed at will should the patient want to upgrade the hardware.
Finally, Gertrude had the surgery and still has the link installed in her head. Her link monitors signals generated from her snout so whenever Gertrude smells something tastey, the Link picked up and recorded those signals.
