The world of tomorrow will be a place where factories grow their outputs locally, almost like farms in previous eras. Drones and robots will be ubiquitous. The human genome will be an elastic thing, and so, necessarily, will be the very idea of the human itself. Life spans will be much longer than our own. Many will disappear almost entirely into virtual worlds. What once seemed a settled social contract will contort and buckle. Learning to live and thrive in this world is going to be a part of everyone’s life in the twenty-first century.
