In the aerospace industry, I'll say that if you look at the first 100 years of aerospace, you'll see that an aircraft was a tube with wings on it. Perhaps not in my lifetime but in my children's lifetime, I think an aircraft will look different. It will look more like a boomerang. We won't have window seats. People will be inside this boomerang and will use cameras and whatnot to see what's going on outside.
That will drive a whole level of fundamental technology that will be different: the aerodynamics, the materials, the structures, the electrical power, the distributed power, and the alternate fuel sources for that. I don't think it will be in my lifetime, but an aircraft will look completely different in the lifetime of our kids.
