Elon Musk claims his mysterious brain chip will allow people to hear previously impossible sounds

Elon Musk has revealed more details about his mysterious brain-computer interface startup, claiming it will allow people to hear sounds that were previously beyond their range. Neuralink's brain chip technology could also help restore movement to someone with a fully severed spinal cord, according to Musk. The SpaceX and Tesla boss founded Neuralink in 2016 but has only held one major public presentation about how its technology will actually work. The ultimate aim is to provide a direct connection between a brain and a computer, using a "sewing machine-like" device to stitch threads to an implanted brain chip. A research paper published last year in conjunction with the event explained how these threads would connect to a single USB-C cable to provide "full-bandwidth data streaming" to the brain.
