While addressing an event at Neuralink’s headquarters in Fremont, California, Elon Musk found himself hanging out with a passel of Yucatan pig. Several of those pigs had previously undergone a surgical procedure in which a robot placed the latest version of Neuralink’s computing implant or chip into their brains. As a result, the brain activity of these enhanced pigs could be transmitted wirelessly to a nearby computer, allowing onlookers at the event to watch the animals’ neurons fire as veterinarians stroked their snouts. Musk spoke passionately at the event about the potential for the technology to address brain injuries and other brain related disorders. “The neurons are like wiring, and you sort of need an electronic thing to solve an electronic problem,” he said.
