In other words, there's nothing to complain about until runners with artificial legs start winning.
That day may not be far off. Artificial legs, unlike human legs, can be improved through engineering, and the companies that make them are hard at work on it. The model used by Pistorius is "a custom foot for track and field sports" with "optimal" sprinting ability, "superior functionality," and an "efficient energy return," according to the manufacturer's Web site. Other models promise "enhanced forward propulsion," "maximum performance," and "the highest energy storage and return capability on the market."
And that's just the beginning. The company's "bionic" site describes its work on "power motion," "neurosensing," and "artificial intelligence." Its introductory video declares, "The destination is life without limitations."
Well, maybe one limitation: You won't be allowed to run in the Olympics with your neurosensing, AI-controlled bionic legs. You'll have to run in the Paralympics with all the other superhuman athletes. It's only fair.
