Review: Homo Deus

Harari.jpg

Yuval Harari is the Van Gogh of historians—a renegade unafraid to paint in bright colours.  In his new book Homo Deus, he lays out trajectories for the future of humanity that are grounded in painstaking historical analysis. This is an essentially conservative pursuit, yet Harari's prophesies are pure sci-fi. He imagines the rise of bio-medically "upgraded" superhumans in a world where "highly intelligent non-conscious algorithms" supplant human consciousness. Techno-humanism, says he, will obliterate the historic delusion that human life is sacred. The good news? We won't miss such conceits in a world where global information systems know us better than we know ourselves.
