Who Is Elon Musk's New Brain-Computer Interface For?

On Friday, Elon Musk's company Neuralink introduced the world to three pigs who seemed indistinguishable. Yet Gertrude, who was both shy and stubborn, had a secret: Two months prior, her brain had been implanted with Neuralink's newest version of a brain-computer interface, or BCI. She looked just like another pig with no such device and a third who had had a similar device in and then removed. As Gertrude walked around doing pig things, viewers saw a display of her real-time brain activity. "If the device is lasting in the pig, as it lasted in there for two months and going strong, then that's a good sign the device is robust for people," Musk said.
