Text 1A4-I

   By the middle years of the 20th century, the optimistic story of limitless progress through scientific and technological advance came to be rivalled and sometimes overshadowed by a much more pessimistic, even apocalyptic vision of the trajectory of the modern project. It began to seem increasingly possible that technology would come to master its creators and carry humanity toward unforeseen and possibly catastrophic outcomes.

   Premonitions of technological wizardry leading to disasters are extremely old, dating back at least to the myth of Icarus, who is said to have fatally fallen into the sea after flying too close to the sun on wings his father, Daedalus, constructed. As the Industrial Revolution gathered steam, dark anticipations became increasingly widespread, in works such as Mary Shelley’s Frankenstein; or, the Modern Prometheus and Karel Capek’s R.U.R. Perhaps technology, not man, was “in the saddle,” as Henry Adams worried. And perhaps machines, becoming ever more capable and interconnected, were the next step in the evolution of life, destined to dominate and eventually eliminate humanity, as Samuel Butler warned. The contours of the future, H. G. Wells announced in one of his famous lectures, “The Discovery of the Future,” were difficult to discern but would surely be unlike the past or the present, and definitely included disasters of new types and magnitudes.

   In the ghastly world wars, technological advances empowered barbarism on a new scale, destroying the credibility of the simple modernist faith that more potent tools are a straight path to human betterment. Rather, technological advance has produced a cornucopia of double-edged swords, with amplified possibilities for both progress and disaster. A growing herd of horsemen of the anthropogenic apocalypse have ominously appeared on the human horizon of possibility: nuclear weapons, genetic engineering, total surveillance despotism, runaway artificial intelligence, and rampant environmental decay.
