Its starting point is the annual Turing Test, which pits artificial intelligence programs against people to determine if computers can “think.”Named for computer pioneer Alan Turing, the Tur­ing Test convenes a panel of judges who pose questions—ranging anywhere from celebrity gossip to moral conundrums—to hidden contestants in an attempt to discern which is human and which is a computer. The machine that most often fools the panel wins the Most Human Computer Award. But there is also a prize, bizarre and intriguing, for the Most Human Human.In 2008, the top AI program came short of passing the Turing Test by just one astonishing vote. In 2009, Brian Christian was chosen to participate, and he set out to make sure Homo sapiens would prevail.The author’s quest to be deemed more human than a com­puter opens a window onto our own nature. Interweaving modern phenomena like customer service “chatbots” and men using programmed dialogue to pick up women in bars with insights from fields as diverse as chess, psychiatry, and the law, Brian Christian examines the philosophical, bio­logical, and moral issues raised by the Turing Test.One central definition of human has been “a being that could reason.” If computers can reason, what does that mean for the special place we reserve for humanity?

    With its sequence of specially designed assignments and in-depth discussions, it effectively bridges the gap between color theory and practice to inspire confidence and understanding in anyone who works with color.

    Everett, then a Christian missionary, arrived among the Pirahã in 1977–with his wife and three young children–intending to convert them. What he found was a language that defies all existing linguistic theories and reflects a way of life that evades contemporary understanding: The Pirahã have no counting system and no fixed terms for color. They have no concept of war or of personal property. They live entirely in the present. Everett became obsessed with their language and its cultural and linguistic implications, and with the remarkable contentment with which they live–so much so that he eventually lost his faith in the God he’d hoped to introduce to them. Over three decades, Everett spent a total of seven years among the Pirahã, and his account of this lasting sojourn is an engrossing exploration of language that questions modern linguistic theory. It is also an anthropological investigation, an adventure story, and a riveting memoir of a life profoundly affected by exposure to a different culture. Written with extraordinary acuity, sensitivity, and openness, it is fascinating from first to last, rich with unparalleled insight into the nature of language, thought, and life itself.
