Why Brain Implants Are More Than a Sci-Fi Fantasy
Startups have developed chips that allow people to control machines with their thoughts. Billionaires are betting these brain-computer interfaces could become everyday consumer tech.
Science fiction has long imagined a world where our brains interact with machines to restore and augment our abilities — think of the neural implants that connected to Geordi La Forge’s visor in Star Trek or allowed Alex Murphy to be reborn as cyborg law enforcer in RoboCop.
In the real world, researchers have been working for decades on so-called brain-computer interfaces to help people who suffer from paralysis, blindness, hearing loss, and more, regain function. Some individuals have used these devices to control a computer cursor with their minds; others have managed to move a robotic arm or transcribe some of their thoughts into text.
