Yuval Noah Harari is the star historian who shot to fame with his international bestseller Sapiens: A Brief History of Humankind. In that book Harari explained how human values have been continually shifting since our earliest beginnings: once we placed gods at the centre of the universe; then came the Enlightenment, and from then on human feelings have been the authority from which we derive meaning and values. Now, using his trademark blend of science, history, philosophy and every discipline in between, Harari argues in his forthcoming book Homo Deus: A Brief History of Tomorrow, our values may be about to shift again – away from humans, as we transfer our faith to the almighty power of data and the algorithm.
In conversation with Kamal Ahmed, the BBC’s economics editor, Harari examined the political and economic revolutions that look set to transform society, as technology continues its exponential advance. What will happen when artificial intelligence takes over most of the jobs that people do? Will our liberal values of equality and universal human rights survive the creation of a massive new class of individuals who are economically useless? And when Google and Facebook know our political preferences better than we do ourselves, will democratic elections become redundant?
As the 21st century progresses, not only our society and economy but our bodies and minds could be revolutionised by new technologies such as genetic engineering, nanotechnology and brain-computer interfaces. After a few countries master the enhancement of bodies and brains, will they conquer the planet while the rest of humankind is driven to extinction?
