I have called this phenomenon “the hummingbird effect”: the process by which an innovation in one field sets in motion transformations in seemingly unrelated fields. The taste for coffee helped create the modern institutions of journalism; a handful of elegantly decorated fabric shops helped trigger the industrial revolution. When human beings create and share experiences designed to delight or amaze, they often end up transforming society in more dramatic ways than people focused on more utilitarian concerns.
