Startup to develop brain-reading 'beanie' that turns thoughts into text

US-based startup Sabi is developing a brain wearable, like a beanie, that can decode people's thoughts and turn them into text on a computer screen. Billionaire Vinod Khosla, the startup's lead investor, said, "If you're going to have a billion people use brain-computer interface...every day, it can't be invasive." Rahul Chhabra, a BITS Pilani graduate, co-founded the startup.
