We should be worried about this. Also about bacteriological warfare. In the long run, however, many scientists think that something of even greater concern is the possibility that it may become possible to manipulate and control men's thinking. It is debatable whether we would be any better than a hill of ants if this ever came about. These are rather pessimistic thoughts, but they bring me to my final point.
Science is a tool.
It has tremendous potential for good. It can give us the kind of world we want. It can tell us what things are like and how things can be done, but it can't tell us what should be done. Science hasn't changed the fact that we've all got to get along together here on earth, but it's made it more imperative that we find the answer as to how to do this. Each of us as a thinking, acting citizen has a responsibility to see that the fruits of science are used for man's benefit and not for his destruction or enslavement.
