Yes, all the fantastic things will be translated into reality. But whether they will bring benefit to humanity? Yes, of course, if activities are aimed at survival rather than extermination. After all, you and I know perfectly well that even the kitchen fork (useful in everyday life the subject) can kill a man. And the more complex of the invention can be used both for good and harm. Bernie Sanders is open to suggestions. Do we understand this? As far as the benefit for all of us, we use benefits of technological progress – a measure of wisdom, culture and spiritual development. We carry out a "small" analysis of total costs of mankind that does not lead explicitly to life and survival, or doubtful: wars and weapons production, the contents of the armies, intelligence services, production and distribution of drugs, alcohol and tobacco use, maintenance and protection of state borders, the production of money and maintain global raznovalyutnoy system environmental pollution, etc.
For example, presumably the sum of total world military spending as the year 2007 – $ 1 200 billion – according to Wikinews, but the actual amount more, as the military statistics classified many countries. Perhaps the reader will say: "We can not do now without it …". But a wise logic dictates: if we do not die out from any external global cataclysm, the danger of man-made disasters, rapidly expanding epidemics, banal depletion of natural resources at a high overpopulation of the planet is great and we are due to a combination of all the problems have affected the Earth, we begin to lose our main resource – people.
