Neuralink is building a brain-machine interface as well as a little robot that installs it into your skull.

Neuralink, the mysterious neuroscience company backed by Elon Musk, is expected to reveal more details about its plans to connect computers to human brains on Friday. While the development of this futuristic-sounding tech is still in its early stages, the presentation is expected to demonstrate the second version of a small, robotic device that inserts tiny electrode threads through the skull and into the brain. Musk says he’ll “show neurons firing in real-time. The matrix in the matrix.”
