“Over the past century, humankind has managed to mostly overcome famine, plague, and war.”
“What will replace these at the top of the human agenda [in the coming century?]”
Homo Deus: A Brief History of Tomorrow (2016) by Noah Yuval Harari is a follow-up to his previous book Sapiens: A brief History of Humankind. While Sapiens explored the history of humanity, Homo Deus helps us to imagine the possibilities for the future of humanity, considering the stupendous rapid advancement in technology and science.
The book argues that the human agenda will shift towards overcoming death and creating artificial life, with the main products of the twenty-first century economy being bodies, brains, and minds. This revolution, when fulfilled, would create a class of “useless” humans. The book explores how with the current progress of science and technology, non-conscious intelligent algorithms may soon understand humans better than their organic brains can understand themselves. This unsettling but possible next step of human evolution, from organic to inorganic, may uproot the current values of humanity such as liberty, equality, human rights, and replace them with a new value system; one that values any entity or being by its ability to contribute to data processing. This data value system is introduced as dataism and the book highlights how this has already taken root in much of our world.
The book challenges readers to consider what would happen to society, politics, and daily life when dataism takes hold. It asks us to reflect on what we might choose to act on, or not act on, in order to ensure that our species are not replaced by machines.
Overall, this book is a 4/5 due to its thought-provoking nature and accessibility to a wide range of audience, similar to Sapiens. However, I would rate it slightly lower than Sapiens since a third of the book seems to rely heavily on the ideas of Sapiens. Still, I think it is an essential reading for anyone who wants to ponder about the future of our species; but do note that you ought to read Sapiens before this book.
