I was honored to talk about my late friend Paul Allen at the Forbes Philanthropy Summit. He was one of the most intellectually curious people I’ve ever known. As a kid, he seemed to be interested in just about everything. And as an adult, that curiosity continued to influence every part of his life -- including his philanthropy, which will continue to benefit society for decades to come. I wish he had gotten to see all of the good his curiosity and generosity will do for the world.
