Who will be lucky enough to be chosen? Mostly, the cleverest one. Therefore, a man who has ordinary IQ will be hard to live. This situation can be called genetic discrimination. Of course, it’s bad to the stability of society. What’s worse, if some terrorists mastered this technology, what our world be? They might regard the technology as a weapon, which could destroy human beings and ruin the earth. We would be under the control of evil power and live with pain forever. In the end, I want to say that I’m not sensationalizing it. It’s a real choice we have to make. Science or Liberty? It seems a easy thing but humans are curious and want to explore by nature. If we want to enjoy our life and appreciate our homeland, we must calm down, forbear our strong desire. Don’t forget that we’re never the overlord of our planet, but only the quests of the earth.
