We live in a time of extraordinary change -- change that's reshaping the way we live, the way we work, our planet, our place in the world. It's change that promises amazing medical breakthroughs, but also economic disruptions that strain working families. It promises education for girls in the most remote villages, but also connects terrorists plotting an ocean away. It's change that can broaden opportunity, or widen inequality. And whether we like it or not, the pace of this change will only accelerate.
