On December 31, 2025, American business magnate Elon Musk took to social media to declare that his brain - computer interface firm, Neuralink, is set to kick off large - scale production of brain - computer interface devices in 2026. Moreover, it will introduce a highly efficient, almost entirely automated surgical procedure. A particularly noteworthy aspect is that the electrode wires of the device will directly pierce through the dura mater, eliminating the need for resection. As of September 2025, a total of 12 individuals across the globe have had Neuralink devices implanted, with these devices amassing over 15,000 hours of usage. Neuralink currently has three product lines aimed at patients suffering from motor disorders, visual impairments, and neuromodulation disorders. Looking ahead, the company intends to incrementally boost the number of electrodes in the implanted chips over the next few years. It also plans to broaden the range of applications, with the long - term ambition of building a 'whole - brain interface' that enables effortless connection between biological brains and external machines.
