The scientists of today are not utilising their knowledge for the good of the society but to enhance power of a country or they are in the rat race to become a Superpower.The blame should come on politicians because they give money to scientists with a tag of what they are supposed to invent.The laboratory finds the chemical.The final invention like an atom bomb ,laser bomb ,robotics to be used for war surprises everyone. The general public never demanded for such things in their life from their politicians but the race to become most powerful country on this planet leads to wars which is not good for mankind.
