Still, there's a significant change on the way; a subtle shift in how some sporting events are viewed. Let me explain.
Sporting events are - for the most part - aspirational. The athletes are typically in better physical condition, have better equipment and are paid more than those watching. It's been that way for quite some time.
On the spectator side of the fence it is - currently, anyway - quite a different story. Athletes do watch other athletes, but it's a minority.
Before we get in to that though, a quick thought on 'enhanced prosthetics'. And yes, it's all related.
Without going into a full history of prosthetic devices, it's fair to say that they've gone from devices which look like the body part they're replacing to devices which function like the body part they're replacing to devices which function better than the body part they're replacing. Hugh Herr's recent TED talk (highly recommended) will confirm that.
Added to that are several devices aimed at aiding & enhancing various functions. Devices that a fully able-bodied person could wear in order to run more easily (for longer distances), carry heavier-than-usual loads and so on.
At some point (and not that far away) many prosthetic devices will look and feel like the body parts they emulate, and the assistive devices will go from 'expensive, clunky prototypes' to slick commercial products. From a quick glance you won't even know they're there.
