2 hours ago
AI summary
A man with ALS has used a brain implant to communicate independently for over 3,800 hours over two years, producing nearly 2 million words at an average speed of 56 words per minute. The study, published in Nature Medicine by researchers at the University of California, Davis, reports accuracy rates of either 99% (according to The Next Web) or 92% (according to The Register). The system allows the patient to work a full-time job without needing researchers present.
