I will tell you a story: I just got back from a plant in Dnipropetrovsk. Only 20 years ago, it was a highly classified facility that produced missiles and satellites for the Soviet Union. Today, I saw with my own eyes: it is producing the first stage of parts for the US-designed Stanford Torus space station in collaboration with scientists from the United States. You cannot imagine the level of cooperation and trust this requires. Who could have imagined that 20 years ago, during the Cold War?This is why I am optimistic about the future, because I believe the future will belong to all sorts of integration. I believe mankind is facing difficult challenges that will require a high degree of integration to resolve.
