Some weeks ago, a nine-year-old macaque monkey called Pager successfully played a game of Pong with its mind. While it may sound like science fiction, the demonstration by Elon Musk’s neurotechnology company Neuralink is an example of a brain-machine interface in action (and has been done before). A coin-sized disc called a “Link” was implanted by a precision surgical robot into Pager’s brain, connecting thousands of micro threads from the chip to neurons responsible for controlling motion. Brain-machine interfaces could bring tremendous benefit to humanity. But to enjoy the benefits, we’ll need to manage the risks down to an acceptable…This story continues at The Next Web
