Earth on the Cusp of the Twenty-Second Century How the world has changed in the last seventy-six years. In 1948, scientists ran the first computer program, and "the Ultimate Car of the Future," the futuristic, three wheeled Davis Divan, debuted. Since then, a succession of inventions-the personal computer, the internet, the World Wide Web, smart phones and social media-have transformed every aspect of our lives. The next seventy-six years will change things too, in ways we can barely even begin to imagine. Culture, climate change, politics and technology will continue to reshape the world. Earth in 2100 will be as unrecognizable to us as today would be to someone from 1948. Eighteen writers tackled this challenge, creating an amazing array of sci-fi possibilities. From emotional AI's to photosynthetic children, from virtual worlds to a post-urban society, our writers serve up compelling slices of life from an Earth that's just around the corner. So dive in and and take a wild ride into these amazing visions of our collective future.
