A Chinese state-backed company on Thursday unveiled a brain chip similar to the technology developed by Elon Musk's startup Neuralink. The company, Beijing Xinzhida Neurotechnology, developed a brain-computer interface (BCI) implant, called Neucyber, that has been tested on a monkey, allowing it control a robotic arm with only its thoughts, according to the state-run Xinhua news agency, which added that the technology was "independently developed" and China's first "high-performance invasive BCI".
