Hello World: Being Human in the Age of Algorithms

Mathematician Hannah Fry explores the pervasive role of algorithms in modern life, moving beyond technical jargon to examine their human implications. Through accessible explanations of underlying mathematics and relatable real-world stories, she reveals how automated systems operate in sectors ranging from medicine and justice to transport and finance. Fry highlights the tension between the promise of efficiency and the risk of embedding human bias into code, asking whether these systems truly improve upon the flawed human processes they replace.

The book adopts a conversational yet rigorous tone, bridging the gap between academic computer science and public understanding. It serves as a critical guide for navigating a world increasingly governed by invisible code, encouraging readers to interrogate the power, limitations, and ethical dimensions of the tools that shape their daily decisions.
