In the coming decades, the technology that enables virtual and augmented reality will improve beyond recognition. Within a century, world-renowned philosopher David J. Chalmers predicts, we will have virtual worlds that are impossible to distinguish from non-virtual worlds. But is virtual reality just escapism? In a highly original work of 'technophilosophy', Chalmers argues categorically, no: virtual reality is genuine reality. Virtual worlds are not second-class worlds. We can live a meaningful life in virtual reality—and increasingly, we will. Drawing on examples from pop culture, literature and film that help bring philosophical issues to life, Reality+ is a mind-bending journey through virtual worlds, illuminating the nature of reality and our place within it.
