Historian Niall Ferguson chooses that present-day metaphor in a new Newsweek article to describe the problems Western societies face today:

The West first surged ahead of the Rest after about 1500 thanks to a series of institutional innovations that I call the “killer applications”:

1. Competition. Europe was politically fragmented into multiple monarchies and republics, which were in turn internally divided into competing corporate entities, among them the ancestors of modern business corporations.

2. The Scientific Revolution. All the major 17th-century breakthroughs in mathematics, astronomy, physics, chemistry, and biology happened in Western Europe.

3. The Rule of Law and Representative Government. An optimal system of social and political order emerged in the English-speaking world, based on private-property rights and the representation of property owners in elected legislatures.

4. Modern Medicine. Nearly all the major 19th- and 20th-century breakthroughs in health care were made by Western Europeans and North Americans.

5. The Consumer Society. The Industrial Revolution took place where there was both a supply of productivity-enhancing technologies and a demand for more, better, and cheaper goods, beginning with cotton garments.

6. The Work Ethic. Westerners were the first people in the world to combine more extensive and intensive labor with higher savings rates, permitting sustained capital accumulation.

For hundreds of years, these killer apps were essentially monopolized by Europeans and their cousins who settled in North America and Australasia. They are the best explanation for what economic historians call “the great divergence”: the astonishing gap that arose between Western standards of living and those in the rest of the world. …

… Beginning with Japan, however, one non-Western society after another has worked out that these apps can be downloaded and installed in non-Western operating systems. That explains about half the catching up that we have witnessed in our lifetimes, especially since the onset of economic reforms in China in 1978.

Now, I am not one of those people filled with angst at the thought of a world in which the average American is no longer vastly richer than the average Chinese. Indeed, I welcome the escape of hundreds of millions of Asians from poverty, not to mention the improvements we are seeing in South America and parts of Africa. But there is a second, more insidious cause of the “great reconvergence,” which I do deplore—and that is the tendency of Western societies to delete their own killer apps.
