I've covered this sort of thing in the past and I reiterate it again here today with this latest story because it looks to me like these interfaces are getting more sophisticated as time goes by. It describes "three clinical trial participants with tetraplegia, each of whom was using the investigational BrainGate BCI that records neural activity directly from a small sensor placed in the motor cortex, were able to navigate through commonly used tablet programs, including email, chat, music-streaming, and video-sharing apps." It gives me hope for the day when I'm a brain in a vat fed nothing but artificial blood.
