This AI-powered "black box" could make surgery safer

The operating room has long been defined by its hush-hush nature--what happens in the OR stays in the OR--because surgeons are notoriously bad at acknowledging their own mistakes. Grantcharov jokes that when you ask "Who are the top three surgeons in the world?" a typical surgeon "always has a challenge identifying who the other two are." But after the initial humiliation over watching himself work, Grantcharov started to see the value in recording his operations. "There are so many small details that normally take years and years of practice to realize--that some surgeons never get to that point," he says. "Suddenly, I could see all these insights and opportunities overnight."
