I am both a huge fan of the Star Trek Franchise (especially TNG) and a huge critic of the widespread interpretation of the show as some sort of perfect and attainable utopia. Widespread militarization, existential malaise and a number of other issues actually depict a sort of perverse, juvenile sketch of utopia. Yet there is no doubt that it has been highly influential in how we think about the future as well as an inspiration in the development of technologies.
The most common reason given for the perfection of the fictional Star Trek universe is that it has evolved past money. It is often suggested that money was the greatest cause of past evils and ridding our species of its use allowed us to make leaps and bounds forward. This is a rather unsophisticated simplification of human economies that does not apply to current humans who do not possess the technologies that make Star Trek possible. However, we are beginning to see some of the technologies in the show become real possibilities. Take the medical device, the Tricorder, which inches closer every year thanks to the sort of competition that people in the ST universe are too evolved for.
Yet the real reason that the ST universe can afford the luxury of abandoning currency lies mostly in the very specific technology of the replicator, which can provide humans with basic needs with matter created from unlimited energy. Well, it seems that we may be close to taking some of the first steps towards replicators as scientists claim they will soon be able to create matter from light. Now all we need is the free unlimited energy to power it and Voilà! Utopia.
As other technologies already available begin to make large scale production and centralized political and economic systems obsolete, we are already beginning to see the rise of new economic paradigms. It has suddenly become likely that the luxuries afforded to the ST universe will be available to us in the near future. As that luxury increases we will move away from Industrialism and most of its economic paradigms, as well as its social and political ones. Soon it may be possible to leave the slavery of wage employment and produce things of value to ourselves and others, not for mere survival, but for living.
