In the 21st century, the whole idea of "guns" and "gunpowder" seems incredibly sad. Let's ignore "hunting" because there just are not that many people who officially hunt any more. Today a gun is used to do one of two things:
- To stop someone when that someone does something that you do not like (aka murder)
- To stop a group of people when they do something that you do not like (aka war)
Currently the technology we use is a hand cannon. The cannon hurtles a small piece of metal at high speed at the person we wish to kill.
Because we have seen so many science fiction films, we tend to think of a "blaster" or "phaser" as the next stage of development in the arms race. We also tend to think of some sort of "shield" as a way of blocking a phaser (or perhaps even small high-speed metal objects).
The question I would ask instead is this: "Is there a way to eliminate the need for murder and war?" Can human beings ever get enough control of their emotions, and develop ways of communicating with each other, and have shared concepts of right and wrong, so that the need to kill one another no long exists?
