Chinese state-backed brain-computer interface (BCI) startup NeuCyber Neurotech said its most cutting-edge product is still three years behind Elon Musk's Neuralink. "The benchmark for Beinao-2 is Neuralink...They already have over 20 patients using it," Li Yuan, rotating CEO of NeuCyber, said. Last week, China became the first country to approve an invasive BCI medical device for commercial use.
