If you think in the future, maybe height wont be a problem so wont be important, I dont like that. If everybody has
the same advantages, the advantages will disappear, so this world will be bored. Imagine if everybody could aspire to be as intelligent as Einstein, this would be bored and silly. But maybe discrimination could dissapear??? I dont think so, humans would create another things that could make the difference. I am just saying that ADN cant be completily changed, becuase it would create a bored world.
