Artificial Intelligence is a phrase that often promotes a strong reaction in a lot of people who hear it. There are the gloom and doom prognosticators who tell us that 'Judgement Day', the day the intelligent machines take over and decide we are more trouble than we are worth and wipe us out is near. There are also the overly optimistic prognosticators which tell us that the day AI will take over and we will enter a golden age of humanity beyond our wildest dreams is near. Kasparov charts a course in between these two extremes using the extremely compelling example of his two matches against IBM's Deep Blue. He won the first and lost the second which was the first time a World Chess Champion was defeated by a chess engine. Kasparov uses these matches, his preparation and the preparation the IBM team employed, to paint an interesting picture of both machine and human intelligence. The conclusion he draws is that machine and human intelligence are complimentary to each other and machine intelligence enhances human intelligence to the point where mediocre chess players using chess engines can easily defeat an International Grand Master and this has, in fact, been done. Our future, according to Kasparov, is to embrace what the machines offer us and use them to augment our human intelligence. Throughout the book Kasparov makes the point that research into AI has shown that machines are good at the types of things humans are not and vice versa. Machines can analyze millions of positions per second while humans can only go 4-5 moves in the future, for instance. On the flip side, the human mind can see what tactics are worthwhile and which are not which makes the human mind's search far more effective. The future, according to Kasparov and backed up by real-world results in the chess world, is a synthesis of the two the end result of which is the enhancing of the human mind. If you are interested in AI, chess and the future of expert systems this is one book you'll want to read.
