AI is all the rage, and the buzziest AI buzz surrounds adaptive machine learning computer systems that learn intelligent behavior from massive amounts of data. This is what powers a driverless car, for example. In this book, Hector Levesque shifts the conversation to -good old fashioned artificial intelligence, - which is based not on heaps of data but on understanding commonsense intelligence. This kind of artificial intelligence is equipped to handle situations that depart from previous patterns -- as we do in real life, when, for example, we encounter a washed-out bridge or when the barista informs us there's no more soy milk.Levesque considers the role of language in learning. He argues that a computer program that passes the famous Turing Test could be a mindless zombie, and he proposes another way to test for intelligence -- the Winograd Schema Test, developed by Levesque and his colleagues. -If our goal is to understand intelligent behavior, we had better understand the difference between making it and faking it, - he observes. He identifies a possible mechanism behind common sense and the capacity to call on background knowledge: the ability to represent objects of thought symbolically. As AI migrates more and more into everyday life, we should worry if systems without common sense are making decisions where common sense is needed.

     But Drake’s exploits in his earlier years, though less well known, are even more remarkable. Born into a poor, obscure family, he worked his way rapidly up in the maritime world to his first captaincy. Before long, he was the most successful of all English pirates, admired by his countrymen, hated and feared by the Spanish. Queen Elizabeth and her ministers saw the potential in this rough-mannered but enterprising young man, and gave him their blessing for the first British venture into the Pacific Ocean. This success of this voyage, which lasted for three years, exceeded their wildest hopes. Not only did Drake come home with a vast treasure of captured gold, silver and jewels; he became the first man ever to circumnavigate the globe in a single mission, and bring most of his crew home alive and well. Soon after his triumphant return, Elizabeth knighted this newly rich adventurer, and gave her blessing to his acts of pillage. It was a gesture that made war with Spain inevitable. And Drake’s part in the coming war changed the course of world history. SIR FRANCIS DRAKE: THE QUEEN’S PIRATE tells the extraordinary story of Drake’s early years and his journey around the world on his famous ship, the Golden Hind.
