Homo Deus: A Brief History of Tomorrow

What this book is, and who it's for

Harari's sequel to Sapiens turns the lens from the past 200,000 years to the next two centuries. The opening claim: humanity has largely solved hunger, plague, and war as existential threats — so what becomes the species's project next? Harari's candidates are immortality, happiness, and divinity, pursued through data, biotech, and algorithm. The book is most interesting when it asks the uncomfortable question that the optimist version of futurism avoids: if humans stop being the most useful information-processing systems on Earth, what claim do we have on the systems that replace us? Read this for the future-stakes context most non-fiction skips.
