China became the first country to approve BCIs for medical use in 2026. One volunteer, ALS patient Casey Harrell, has used his implant for three years to speak, browse the web, and work as a climate activist. Researchers at the University of California, Davis have worked with Harrell since his implant in July 2023, improving recognition accuracy and adding features such as a privacy mode and a profanity filter. Harrell called the device \u0026#39;absolutely revolutionary\u0026#39; and said it lets him maintain his income, reconnect with family, and read books to his daughter. The technology remains experimental, with questions about who can benefit and how long the devices will last.\u003c/p\u003e","blueskyPost":"Clinical trials of brain implants are surging.
