In this visionary and fundamentally optimistic book, the legendary oracle of technological change explains how AI will transform our species beyond recognition. Within our lifetimes, 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. Here Kurzweil explains how the Singularity will occur and 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? Drawing on a lifetime's expertise, Kurzweil presents deeply reasoned answers to these questions and argues that we can and will transform life on earth profoundly for the better.
