We are experiencing a technological revolution that raises deep questions about what it means to be "human." Our bodies and minds, once thought to be exclusively our own, will soon be manifestations of an intelligence that will be neither natural nor artificial.

How compatible with humans will a machine with intelligence superior to our own be? Will we coexist, or might our jobs, human relationships, and even our culture collapse under its power?

Who will ultimately possess our "being" and its data?
