It must be right? Just like a mathematical optimization which looks for just one value for x (assuming a global optimum) and discarding the rest of the values (the 'diversity' in x). You see the same thing in pop music, which is optimized for popularity by the music industry. These days pop music sounds much more alike than say pop from the 60s or 70s. Same thing with athletes, in their sport there isn't much variety in physique. Under the neoliberal/capitalist doctrine, which tries to turn everything into a competition, the winners take all and the winners tend to be optimized for the same qualities.
