About the Book
Having looked back at humanity’s history in Sapiens and forward at its distant future in Homo Deus, Yuval Noah Harari turns his focus to the present in 21 Lessons for the 21st Century. Rather than sweeping historical narrative, this book confronts the immediate, urgent questions of today: the disruptive power of artificial intelligence and automation on jobs, the spread of misinformation and “fake news,” rising nationalism, and how individuals can find meaning and resilience in a world changing faster than most institutions can keep up with.
