Physics of the Future: How Science Will Shape Human Destiny and Our Daily Lives by the Year 2100

as democracy is spread around the world.
      (There is another reason why wars are becoming more difficult to wage as the world becomes more affluent and people have more to lose. Political theorist Edward Luttwak has written that wars are much more difficult to wage because families are smaller today. In the past, the average family had ten or so children; the eldest inherited the farm, while the younger siblings joined the church, the military, or sought their fortunes elsewhere. Today, when a typical family has an average of 1.5 children, there is no more surplus of children to easily fill the military and the priesthood. Hence, wars will be much more difficult to wage, especially between democracies and third-world guerrillas.)
    • Nations will weaken but will still exist in 2100. They will still be needed to pass laws and fix local problems. However, their power and influence will be vastly decreased as the engines of economic growth become regional, then global. For example, with the rise of capitalism in the late 1700s and early 1800s, nations were needed to enforce a common currency, language, tax laws, and regulations concerning trade and patents. Feudal laws and traditions, which hindered the advance of free trade, commerce, and finance, were quickly swept away by national governments. Normally, this process might take a century or so, but we saw an accelerated version of this when Otto von Bismarck, the Iron Chancellor, forged the modern German state in 1871. In the same way, this march toward a Type I civilization is changing the nature of capitalism, and economic power is gradually shifting from national governments to regional powers and trade blocs.
      This does not necessarily mean a world government. There are many ways a planetary civilization could exist. It is clear that national governments will lose relative power, but what power will fill the vacuum will depend on many historical, cultural, and national trends that are hard to predict.
    • Diseases will be controlled on a planetary basis. In the ancient past, virulent diseases were actually not so dangerous because the human population was very low. The incurable Ebola virus, for example, is probably an ancient disease that infected just a few villages over thousands of years. But the rapid expansion of civilization into previously uninhabited areas and the rise of cities mean that something like Ebola has to be monitored very carefully.
      When the population of cities hit several hundred thousand to a million, diseases could spread rapidly and create genuine epidemics. The fact that the Black Plague killed perhaps half the European population was an indication, ironically, of progress, because populations had reached critical mass for epidemics and shipping routes connected ancient cities around the world.
      The recent outbreak of the H1N1 flu is thus a measure of our progress as well. Perhaps originating in Mexico City, the disease spread quickly around the globe via jet travel. More important, it took only a matter of months for the nations of the world to sequence the genes of the virus and then create a vaccine for it that was available to tens of millions of people.
    TERRORISM AND DICTATORSHIPS
    There are groups, however, that instinctively resist the trend toward a Type I planetary civilization, because they know that it is progressive, free, scientific, prosperous, and educated. These forces may not be conscious of this fact and cannot articulate it, but they are in effect struggling against the trend toward a Type I civilization. These are:
     
    • Islamic terrorists, who would prefer to go back a millennium, to the eleventh century, rather than live in the twenty-first century.They cannot frame their discontent in this fashion, but, judging from their own statements, they prefer to live in a theocracy where science, personal relations, and politics are all subject to strict religious edicts. (They forget that, historically, the greatness and scientific and technological prowess of the Islamic civilization were matched only by its tolerance of new ideas. These terrorists do not understand the true source of the greatness of the Islamic past.)
    • Dictatorships that depend on keeping their people ignorant of the wealth and progress of the outside world. One striking example was the demonstrations that gripped Iran in 2009, where the government tried to suppress the ideas of the demonstrators, who
