This is part of IEEE Spectrum's SPECIAL REPORT: THE SINGULARITY

Take the idea of exponential technological growth, work it through to its logical conclusion, and there you have the singularity. Its bold incredibility pushes aside incredulity, as it challenges us to confront all the things we thought could never come true—the creation of superintelligent, conscious organisms, nanorobots that can swim in our bloodstreams and fix what ails us, and direct communication from mind to mind. And the pièce de résistance: a posthuman existence of disembodied uploaded minds, living on indefinitely without fear, sickness, or want in a virtual paradise ingeniously designed to delight, thrill, and stimulate.

This vision argues that machines will become conscious and then perfect themselves, as described elsewhere in this issue. Yet for all its show of tough-minded audacity, the argument is shot through with sloppy reasoning, wishful thinking, and irresponsibility. Infatuated with statistics and seduced by the power of extrapolation, ­singularitarians abduct the moral imagination into a speculative no-man’s-land. To be sure, they are hardly the first to spread fanciful technological prophecies, but among enthusiasts and doomsayers alike their ­proposition enjoys an inexplicable popularity. Perhaps the real question is how they have gotten away with it.

The trouble begins with the singularitarians’ assumption that technological advances have accelerated. I’d argue that I have seen less technological progress than my parents did, let alone my grandparents. Born in 1956, I can testify primarily to the development of the information age, fueled by the doubling of computing power every 18 to 24 months, as described by Moore’s Law. The birth-control pill and other reproductive technologies have had an equally profound impact, on the culture if not the economy, but they are not developing at an accelerating speed. Beyond that, I saw men walk on the moon, with little to come of it, and I am surrounded by bio- and nanotechnologies that so far haven’t affected my life at all. Medical research has developed treatments that make a difference in our lives, particularly at the end of them. But despite daily announcements of one breakthrough or another, morbidity and mortality from cancer and stroke continue practically unabated, even in developed countries.

Now consider the life of someone who was born in the 1880s and died in the 1960s—my grandmother, for instance. She witnessed the introduction of electric light and telephones, of auto­mobiles and airplanes, the atomic bomb and nuclear power, vacuum electronics and semi­conductor electronics, plastics and the computer, most vaccines and all anti­biotics. All of those things mattered greatly in human terms, as can be seen in a single statistic: child mortality in industrialized countries dropped by 80 percent in those years.

So on what do intelligent people base the idea that technological progress is moving faster than ever before? It’s simple: a chart of productivity from the dawn of humanity to the present day. It shows a line that inclines very gradually until around 1750, when it suddenly shoots almost straight up.

But that’s hardly surprising. Since around 1750 the world has witnessed the spread of an economic system, by the name of capitalism, that is predicated on economic growth. And how the economy has grown since then! But surely the creation of new markets and the increasingly fine division of labor cannot be equated with technological progress, as every consumer knows.

Age of Invention: Technological optimists maintain that the impact of innovation on our lives is increasing, but the evidence goes the other way. The author’s grand mother [see photo] lived from the 1880s through the 1960s and witnessed the adoption of electricity, phonographs, telephones, radio, television, airplanes, antibiotics, vacuum tubes, transistors, and the automobile. In 1924 she became one of the first in her neighborhood to own a car. The author contends that the inventions unveiled in his own lifetime have made a far smaller difference.
