Waiting for the lights to go out
We've taken the past 200 years of prosperity for granted. Humanity's progress is stalling, we are facing a new era of decay, and nobody is clever enough to fix it. Is the future really that black, asks Bryan Appleyard
The greatest getting-and-spending spree in the history of the world is about to end. The 200-year boom that gave citizens of the industrial world levels of wealth, health and longevity beyond anything previously known to humanity is threatened on every side. Oil is running out; the climate is changing at a potentially catastrophic rate; wars over scarce resources are brewing; finally, most shocking of all, we don't seem to be having enough ideas about how to fix any of these things.
It's been said before, of course: people are always saying the world will end and it never does. Maybe it won't this time, either. But, frankly, it's not looking good. Almost daily, new evidence is emerging that progress can no longer be taken for granted, that a new Dark Age is lying in wait for ourselves and our children....
One of the strangest portents of the end of progress is the recent discovery that humans are losing their ability to come up with new ideas.
Jonathan Huebner is an amiable, very polite and very correct physicist who works at the Pentagon's Naval Air Warfare Center in China Lake, California. He took the job in 1985, when he was 26. An older scientist told him how lucky he was. In the course of his career, he could expect to see huge scientific and technological advances. But by 1990, Huebner had begun to suspect the old man was wrong. "The number of advances wasn't increasing exponentially, I hadn't seen as many as I had expected — not in any particular area, just generally."
Puzzled, he undertook some research of his own. He began to study the rate of significant innovations as catalogued in a standard work entitled The History of Science and Technology. After some elaborate mathematics, he came to a conclusion that raised serious questions about our continued ability to sustain progress. What he found was that the rate of innovation peaked in 1873 and has been declining ever since. In fact, our current rate of innovation — which Huebner puts at seven important technological developments per billion people per year — is about the same as it was in 1600. By 2024 it will have slumped to the same level as it was in the Dark Ages, the period between the end of the Roman empire and the start of the Middle Ages.
The calculations are based on innovations per person, so if we could keep growing the human population we could, in theory, keep up the absolute rate of innovation. But in practice, to do that, we'd have to swamp the world with billions more people almost at once. That being neither possible nor desirable, it seems we'll just have to accept that progress, at least on the scientific and technological front, is slowing very rapidly indeed.
Huebner offers two possible explanations: economics and the size of the human brain. Either it's just not worth pursuing certain innovations since they won't pay off — one reason why space exploration has all but ground to a halt — or we already know most of what we can know, and so discovering new things is becoming increasingly difficult. We have, for example, known for over 20 years how cancer works and what needs to be done to prevent or cure it. But in most cases, we still have no idea how to do it, and there is no likelihood that we will in the foreseeable future.
Huebner's insight has caused some outrage. The influential scientist Ray Kurzweil has criticised his sample of innovations as "arbitrary"; K Eric Drexler, prophet of nanotechnology, has argued that we should be measuring capabilities, not innovations. Thus we may travel faster or access more information at greater speeds without significant innovations as such.
Huebner has so far successfully responded to all these criticisms. Moreover, he is supported by the work of Ben Jones, a management professor at Northwestern University in Illinois. Jones has found that we are currently in a quandary comparable to that of the Red Queen in Through the Looking Glass: we have to run faster and faster just to stay in the same place. Basically, two centuries of economic growth in the industrialised world has been driven by scientific and technological innovation. We don't get richer unaided or simply by working harder: we get richer because smart people invent steam engines, antibiotics and the internet. What Jones has discovered is that we have to work harder and harder to sustain growth through innovation. More and more money has to be poured into research and development and we have to deploy more people in these areas just to keep up. "The result is," says Jones, "that the average individual innovator is having a smaller and smaller impact."
Like Huebner, he has two theories about why this is happening. The first is the "low-hanging fruit" theory: early innovators plucked the easiest-to-reach ideas, so later ones have to struggle to crack the harder problems. Or it may be that the massive accumulation of knowledge means that innovators have to stay in education longer to learn enough to invent something new and, as a result, less of their active life is spent innovating. "I've noticed that Nobel-prize winners are getting older," he says. "That's a sure sign it's taking longer to innovate." The other alternative is to specialise — but that would mean innovators would simply be tweaking the latest edition of Windows rather than inventing the light bulb. The effect of their innovations would be marginal, a process of making what we already have work slightly better. This may make us think we're progressing, but it will be an illusion.
If Huebner and Jones are right, our problem goes way beyond Windows. For if innovation is the engine of economic progress — and almost everybody agrees it is — growth may be coming to an end. Since our entire financial order — interest rates, pension funds, insurance, stock markets — is predicated on growth, the social and economic consequences may be cataclysmic.
Is it really happening? Will progress grind to a halt? The long view of history gives conflicting evidence. Paul Ormerod, a London-based economist and author of the book Why Most Things Fail, is unsure. "I am in two minds about this. Biologists have abandoned the idea of progress — we just are where we are. But humanity is so far in advance of anything that has gone before that it seems to be a qualitative leap"....
Ormerod suspects that capitalism is indeed, like cities, a lasting change in the human condition. "Immense strides forward have been taken," he says. It may be that, after millennia of striving, we have found the right course. Capitalism may be the Darwinian survivor of a process of natural selection that has seen all other systems fail.
Ormerod does acknowledge, however, that the rate of innovation may well be slowing — "All the boxes may be ticked," as he puts it — and that progress remains dependent on contingencies far beyond our control. An asteroid strike or super-volcanic eruption could crush all our vanities in an instant.
