The Death of “Digital”

Words are a powerful vehicle for meaning and understanding, connected to individual or group perspectives, interpretations, and connections. The word “Digital” has been part of our vocabulary landscape for a long time. It was only after reading Nicholas Negroponte’s  book, “Being Digital” in 1995, that I began to be aware of the term and its [...]
