We credit them with inventing the powered airplane. But others had already left ground only to crash. The Wrights didn't just power their way into the sky. They figured out how to stay aloft. They looked at birds.
Birds control their own unstable flight in three dimensions.
Controlling an unstable bicycle in only two dimensions is complex enough. They extended that into 3-D and figured out how to do it using aerodynamic forces. Wilbur was right when he said it might come out differently if time were turned back. But their synergy, based on abstract thinking and practical sense, coupled with a terrifying passion and intensity, would've left Earth changed in some way. Of that I have no doubt.
