My Post yesterday revisited the intersections that shape our future. Convergence across multiple domains sets these intersections in motion. In this context, convergence refers to a virtuous cycle where events in one domain spur action in another. The great inventions (electricity, telephone, and internal combustion engine) were clustered together at the end of the 19th century, forming a virtuous cycle that drove a period of astounding innovation. Several Catalysts drove an enabling convergence across the economy, science, technology, business, geopolitics, and a broader set of societal issues.
