I, for one, welcome our new computer overlords.� So responded Ken Jennings in the final round of one of the most exciting Jeopardy matches in history, in which two of the game�s greatest all-time winners were dominated by a machine called Watson. It was clear to all who were watching that the future had arrived. Stephen Baker�s Final Jeopardy traces the arc of Watson�s �life,� from its birth in the IBM labs to its big night on the podium. We watch as Watson comes to understand language and master everything from history, literature, and science to arts, entertainment, and game strategy. We see how a new generation of Watsons could transform medicine, the law, marketing, even science itself, as machines process huge amounts of data at lightning speed, answer our questions, and possibly come up with new hypotheses. As fast and fun as the game itself, Final Jeopardy shows how smart machines will fit into our world�and how they�ll disrupt it.
