|Science & Tech Spotlight: Brain-Computer Interfaces|
Brain-computer interfaces allow people to control machines using their thoughts. The technology is still largely experimental, but its possibilities are vast. For example, it could help people with paralysis regain control of their limbs and enable servicemembers to operate a drone hands-free on the battlefield. Yet, creating a direct connection between brain and machine may raise concerns. For example, it could give users unfair advantages by enhancing physical and cognitive abilities. Also, hackers could steal data related to a person's brain signals. In this spotlight, we explore these and other policy issues related to this technology.
