Michael Chorost was born almost entirely deaf. Then, later in life, he lost  the little hearing he had in one ear. Hearing aids helped to a point. Today, though, he relies on two cochlear implants -- as he puts it, 180,000 electrodes implanted in his head. He jokes he’s a cyborg --part man, part machine. Chorost’s experience, along with his insatiable curiosity, led him to a career as a science writer. At the Conference of World Affairs in Boulder this week, he’s on a number of panels, including “Your Brain on the Internet.” We’re going to talk with him about a cyborg future and his latest book, “World Wide Mind.”
