Until recently, in all of human history, the number of true cyborgs stood at about 70. Ian Burkhart has kept a count because he was one of them—a person whose brain has been connected directly to a computer.
Burkhart had become quadriplegic in a swimming accident after a wave ran him into a sandbar and injured his spine. He was later able to receive an implant from a research study, which allowed him to temporarily regain some movement in one hand.

In the spring of 1825, Ludwig van Beethoven was struck by a gut ailment so severe that he thought he might die. That summer, after he recovered, he returned to the string quartet he’d been writing before his illness—Quartet No. 15 in A Minor, Op. 132—and added a new segment inspired by his survival.
