Hello World: How to be Human in the Age of the Machine

You are accused of a crime. Who would you rather determined your fate – a human or an algorithm? An algorithm is more consistent and less prone to error of judgement. Yet a human can look you in the eye before passing sentence.


This is the age of the algorithm, the story of a not-too-distant future where machines rule supreme, making important decisions – in healthcare, transport, finance, security, what people watch, where they go - even who is sent to prison. How much should they be relied upon?


Hannah Fry looks at the good, the bad and the downright ugly of the algorithms that surround us. In Hello World she lifts the lid on their inner workings, demonstrates their power, exposes their limitations, and examines whether they really are an improvement on the humans they are replacing.

Judges’ comment: “Hello World is a brilliant and informative account of how algorithms are changing the world we live in and the ethical challenges this creates. This is a book that will make you look at the world differently.”
