Eugenics- science or, better to say, it is a set of beliefs and practices that aims at improving the genetic quality of a human population.
What does it mean exactly? It means that we are able to choose genes for our new generation, for kids basically. We can take all undesirable chromosomes and replace them with the qualities of any personality we like. Replace bad ones with good ones. Possible? Yes! Most importantly, we are almost there. Unethical? Yet… But till the moment when we can control diseases and engineer our body to perfection it will be kind of unethical for us. Illuminated errors allow us to manufacture better human beings in the very near future. May be within the next 10 years or so we will be able to buy a perfect child for ourselves in the shop, but for now we only have an 80% sale on an “unperfect” us.
