by Stephen Baker. Forget chess-a television game show is the ultimate test of a thinking machine. Former Business Week technology writer Baker (The Numerati) delivers a sprightly account of IBM's quest to create a computer program, dubbed Watson, that can win at Jeopardy. Baker deftly explores the immense challenge that Jeopardy-style "question answering" poses to a computer, which must comprehend the nuances, obscurities, and puns of natural language and master everything from Sumerian history to Superbowl winners. Watson is both an information-processing juggernaut, searching millions of documents per second, and a child-like naïf with odd speech impediments that thinks the Al in Alcoa stands for Al Capone (one embarrassing gaffe in a practice match prompted programmers to install a profanity filter). Like a cross between Born Yesterday and 2001: A Space Odyssey, Baker's narrative is both charming and terrifying; as Watson's intelligence relentlessly increases, we envision whole job sectors, from call center operators and marketing analysts to, well, quiz-show contestants, vanishing overnight. The result is an entertaining romp through the field of artificial intelligence-and a sobering glimpse of things to come. The book's final chapter, covering the actual games, which will air in mid-February, was not seen by PW. --Publishers Weekly
