The concept is simple enough. A triangular structure is incredibly strong. Add another brace to make a triangular shape out of the wing, the fuselage, and this new structure. But wait, while this lets you build a lighter wing, now you have the drag of this new structure. Ahh, wait, put an airfoil on this new structure and it can produce lift as well. But wait, aircraft wings are incredibly strong through the concept of bend but don't break (Don't understand that comment? On your next airline flight, sit at the overwing exit and watch what happens to the wing during takeoff). OK, we'll tune the structure of the wing and the new surface until they both deflect the same amount under the same load. But wait, they're joined together so when they flex in one direction, one has to be longer than the other....
It goes on and on like this until only one conclusion can be reached. Aircraft are shaped they way they are because after a little more than a hundred years of refinement, that's the best shape there is. Until we can go outside of the atmosphere, aircraft aren't going to look a whole lot different than they do today. A few small tweaks, but nothing wholesale will change.
Shall we apply your technological wisdom to televisions, computers and space travel?
You are an idiot.
