And since a misread signal can send you jumping off a bridge or in front of a moving car, thought-controlled legs need more stringent programming than equivalent arms. As one of the researchers delicately put it, “If you're using a bionic arm and it misbehaves, the elbow may move slightly. If the prosthetic leg misbehaves . . . that could be quite a safety issue.”
3. Golden State righted itself over the next few months. Kevin Durant suffered an injury which let Stephen Curry be Stephen Curry again, and when Kevin Durant returned, the team had found a balance between their two MVPs.
