Scientific or technological inventions are neither good nor bad in themselves. It is how they are used by us that makes them either good or bad for humankind. Nuclear power immediately springs to mind as a classic example. Man’s ability to fly is another. Aircraft can be used to transport people and goods from one place to another in double-quick time. Or, as we have witnessed all too often, aircraft can be used to drop bombs, kill and maim people, and destroy cities and towns.
