Op-Ed: Why we should worry about Big Tech's investment in a new brain technology (via latimesopinion)
Brain-computer interfaces allow computers to read information out of, or insert information into, a living brain. We will undoubtedly see more headlines about BCIs as new advances build on prior successes.
Capturing signals from a brain map is only the first step in making a useful BCI. Although the location of a brain map is the same across individuals, the details — what patterns of activity within the map— differ from person to person. In a sense, the unique features of your specific brain maps serve as a kind of encryption, shielding your specific thoughts and sensations from would-be eavesdroppers.
Researchers developing BCIs often create such examples by instructing an individual to think specific thoughts at specific times, creating a neural curriculum for the program to learn from. In Pancho’s case the scientists collected nearly 10,000 examples of activity in his speech map while he tried to say common words presented on a screen and another 250 examples while he tried to say sentences built from those words.
