AI is on the brink of a new dawn. And so are we . . .

Telling the difference between humans and computers used to be easy. But artificial intelligence is now so advanced that it is capable of behaving, and even thinking, in ways that have long been considered exclusive to humankind. The time has come to rethink what being human actually means . . .

In The Most Human Human Brian Christian goes to talk to the world's leading artificial intelligences, battling against them in the renowned Turing Test competition, in order to find out what they're capable of - and what makes us unique. The result is a funny, shocking, inspiring, deeply humane and intelligent book that reaches into every aspect of our lives, from work to school, speed-dating to chess, to psychiatry, video games and the criminal law.

'Remarkable. A philosophical joyride. The day a machine creates work of such wit and originality, we should all be very worried.' The Times

'An epic tour of philosophical, linguistic and scientific discovery. We stop off in places as far-flung as existential anxiety, predictive text and Gary Kasparov's defeat by Deep Blue. A lively, personable read and an empowering affirmation of our species.' Time Out

'Lively, thought-stirring, entertaining, invaluable.' New Statesman

'Dense with ideas, terrific.' New Yorker
