It was always going to happen - now it finally has. We have the Olympics and the Paralympics - because the athletes in the Paralympics cannot compete against non-handicapped athletes. Now, at least in some circumstances, it is possible to replace missing biological parts with superior parts (at least for a specific task).
Some athletes will take any advantage they can get. For years now, it has been impossible to win certain events without doping (Tour de France). Remember the biologically male athletes from behind the iron curtain who had themselves surgically altered so that they could compete as women?
If this result stands, as prosthetics continue to improve - how long until some athlete deliberately has an accident requiring their leg to be amputated?
