Brains are the last frontier of privacy (3 minute read)
Several startups and a major tech company are now developing brain-computer interfaces, with some rudimentary versions already popping up in online stores. The concern for these devices is that they are able to read thoughts, which might open up the possibility of discrimination based on what goes on inside a person's head. Devices can already recognize basic emotional states, unspoken words, and imagined movements. The technology has been applied to the area of prosthetics, allowing people to regain control of their limbs. Companies are aiming to create devices that allow typing with thoughts or even merging with AI. These devices will generate huge amounts of neural data, which is potentially one of the most sensitive forms of personal information. This data could be exploited for marketing and has the potential to be used against people who show particular brain patterns, for example, it can be used to tell whether a person had propensities for addiction, depression, or neurological disease.
