Can machines be intelligent? What does intelligence even mean? Can you build it with cogs and springs, or electrons and chips? Why are our computers so sexist and racist? Why do they cheat so much? What if you could capture someone's intelligence with a single number — an Intelligence Quotient, if you like? Am I smart if I do well at pub quizzes? Why is everyone so stupid? And who won the Big IQ contest, James or Chris? It doesn't matter. (It totally does.)
