All new technology created by humans is utilized primarily in weapons. This has been the case for untold millions of years. Humans who do not use discoveries to immediately kill their enemies are killed instead themselves, which means their genes do not get passed on. Mankind is a breed of nutty hominid who therefore makes war for any good reason whenever he is in a position to do so.
There are biowarfare weapons coming soon that will be used in World War III that will be the stuff of science fiction now.
