Electric vehicles, rockets... and now brain-computer interfaces. Elon Musk's newest venture, Neuralink, aims to bridge the gap between humans and artificial intelligence (creating a kind of "symbiosis" or "merging") by implanting tiny chips that can link up to the brain. At a press conference on July 16, Neuralink's ambitious plans were detailed for the first time, showcasing a future (a very distant future!) technology that could help people deal with brain or spinal cord injuries or controlling 3D digital avatars.
