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.

Welcome to 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 we watch, where we go, even who we send to prison. So how much should we rely on them? What kind of future do we want?

In Hello World Hannah Fry lifts the lid on algorithms' inner workings, demonstrates their power, exposes their limitations, and examines whether they really are an improvement on the humans they are replacing.
