Elon Musk demonstrated a Neuralink brain implant in a live pig

Elon Musk has showed off his company Neuralink's brain-computer interface for the first time. In an announcement on 28 August, Neuralink unveiled prototypes of its device and showed off pigs with the devices implanted in their brains. The device resembles a coin with extremely thin wires coming from one side of it. It is designed to be implanted in the skull, with the wires embedded a few millimetres into the surface of the brain. Those wires can then detect when neurons are firing, or emit their own electrical signals to make the neurons fire.
