Richard Kostelanetz's Welcome to the 21st Century is a collection that captures the language of our era in all its strange, fast-changing energy. Kostelanetz's book explores words that have emerged in the 21st century, which elucidate how our speech has been reshaped by screens and networks. Each word feels like a snapshot of life in the digital age, where virality, globalization, and screen fatigue sit side by side. True to Kostelanetz's experimental tradition, each word takes on a poetic quality when expanded into large, bold type. Welcome to the 21st Century invites readers to view our new vocabulary through a new lens, and to consider what kind of future these words are leading us toward.
