This is progress that we seek for. The threat of the imminent extermination of humankind as a result of the Cold War is only a fading memory of the past. However the scene is not yet clear. Infact, more than any time else in the future everything is in excess today. The question is whether it is good or whether it is bad.
People change fast, societies change in an irrevocable fashion.
There are always nations, races, people who thrive on change. Change is imminent. Our success as humans comes with our capacity to adapt. But these changes bring us to question the very fundamentals on which our societies are based on. Whether it be the result of the proliferation of nuclear know-how or whether it be the ethics of cloning.
