Over the last few weeks, media around the world have been saturated with stories about how technology is destroying politics. In autocracies like China, the fear is of ultra-empowered Big Brother states, like that in George Orwell's "1984." In democracies like the United States, the concern is that tech companies will continue to exacerbate political and social polarization by facilitating the spread of disinformation and creating ideological "filter bubbles," leading to something resembling Aldous Huxley's "Brave New World."

In fact, by bringing about a convergence between democracy and dictatorship, new technologies render both of these dystopian visions impossible. But that doesn't mean there is nothing to fear.

Much of the coverage of the Chinese Communist Party's recent congress focused on President Xi Jinping's consolidation of power. He is, observers warn, creating an information-age dictatorship, in which the technologies that were once expected to bring freedom to China's 1.4 billion citizens have instead enabled him to entrench his own authority. By providing the government with highly detailed information on the needs, feelings and aspirations of ordinary Chinese, the internet allows China's leaders to pre-empt discontent. In other words, they now use Big Data, rather than brute force, to ensure stability.
