By the end of this decade, AI will exceed human levels of intelligence. During the 2030s, it will become ''superintelligent'', vastly outstripping our capabilities by almost every measure and enabling dramatic new interventions in our bodies. By 2045, we will be able to connect our brains directly with AI, enhancing our intelligence a millionfold and expanding our consciousness in ways we can barely imagine. This is the Singularity. Ray Kurzweil is one of the greatest inventors of our time with over 60 years'' experience in the field of Artificial Intelligence. Dozens of his long-range predictions about the rise of the internet, AI and bioengineering have been borne out. In this visionary and fundamentally optimistic book, Kurzweil explains how the Singularity will occur and explores what it will mean to live free from the limits of biology. What will we choose if our bodies need no longer define us? What new realms of beauty, connection and wonder might we inhabit? Who will we become if our minds can be stored and duplicated? How will we navigate the risks presented by such awesomely powerful technology? Drawing on a lifetime''s expertise and marshalling the evidence of today''s rapidly accelerating advances, Kurzweil presents deeply reasoned answers to these questions and argues that we can and will transform life on earth profoundly for the better.
