SURFING the web and making free internet phone calls on your Wi-Fi laptop, listening to your iPod on the way home, it often seems that, technologically speaking, we are enjoying a golden age. Human inventiveness is so finely honed, and the globalised technology industries so productive, that there appears to be an invention to cater for every modern whim.
But according to a new analysis, this view couldn't be more wrong: far from being in technological nirvana, we are fast approaching a new dark age. That, at least, is the conclusion of Jonathan Huebner, a physicist working at the Pentagon's Naval Air Warfare Center in China Lake, California. He says the rate of technological innovation reached a peak a century ago and has been declining ever since. And like the lookout on the Titanic who spotted the fateful iceberg, Huebner sees the end of innovation looming dead ahead. His study will be published in Technological Forecasting and Social Change.
It's an unfashionable view. Most futurologists say technology is developing at exponential rates. Moore's law, for example, foresaw chip densities (for which read speed and memory capacity) doubling every 18 months. And the chip makers have lived up to its predictions. Building on this, the less well-known Kurzweil's law says that these faster, smarter chips are leading to even faster growth in the power of computers. Developments in genome sequencing and nanoscale machinery are racing ahead too, and internet connectivity and telecommunications bandwith are growing even faster than computer power, catalysing still further waves of innovation.
But Huebner is confident of his facts. He has long been struck by the fact that promised advances were not appearing as quickly as predicted. "I wondered if there was a reason for this," he says. "Perhaps there is a limit to what technology can achieve."
In an effort to find out, he plotted major innovations and scientific advances over time compared to world population, using the 7200 key innovations listed in a recently published book, The History of Science and Technology (Houghton Mifflin, 2004). The results surprised him.
Rather than growing exponentially, or even keeping pace with population growth, they peaked in 1873 and have been declining ever since (see Graphs). Next, he examined the number of patents granted in the US from 1790 to the present. When he plotted the number of US patents granted per decade divided by the country's population, he found the graph peaked in 1915.
The period between 1873 and 1915 was certainly an innovative one. For instance, it included the major patent-producing years of America's greatest inventor, Thomas Edison (1847-1931). Edison patented more than 1000 inventions, including the incandescent bulb, electricity generation and distribution grids, movie cameras and the phonograph.
Medieval future
Huebner draws some stark lessons from his analysis. The global rate of innovation today, which is running at seven "important technological developments" per billion people per year, matches the rate in 1600. Despite far higher standards of education and massive R&D funding "it is more difficult now for people to develop new technology", Huebner says.
Extrapolating Huebner's global innovation curve just two decades into the future, the innovation rate plummets to medieval levels. "We are approaching the 'dark ages point', when the rate of innovation is the same as it was during the Dark Ages," Huebner says. "We'll reach that in 2024."
But today's much larger population means that the number of innovations per year will still be far higher than in medieval times. "I'm certainly not predicting that the dark ages will reoccur in 2024, if at all," he says. Nevertheless, the point at which an extrapolation of his global innovation curve hits zero suggests we have already made 85 per cent of the technologies that are economically feasible.
But why does he think this has happened? He likens the way technologies develop to a tree. "You have the trunk and major branches, covering major fields like transportation or the generation of energy," he says. "Right now we are filling out the minor branches and twigs and leaves. The major question is, are there any major branches left to discover? My feeling is we've discovered most of the major branches on the tree of technology."
But artificial intelligence expert Ray Kurzweil - who formulated the aforementioned law - thinks Huebner has got it all wrong. "He uses an arbitrary list of about 7000 events that have no basis as a measure of innovation. If one uses arbitrary measures, the results will not be meaningful."
Eric Drexler, who dreamed up some of the key ideas underlying nanotechnology, agrees. "A more direct and detailed way to quantify technology history is to track various capabilities, such as speed of transport, data-channel bandwidth, cost of computation," he says. "Some have followed exponential trends, some have not."
Drexler says nanotechnology alone will smash the barriers Huebner foresees, never mind other branches of technology. It's only a matter of time, he says, before nanoengineers will surpass what cells do, making possible atom-by-atom desktop manufacturing. "Although ...читать дальше

Хрень какая-то.
"a new dark age" - звучит страшно и у обычного люда вызывает неправильные ассоциации.
А базару-то всего о том, что раньше число открытий и инноваций было намного выше чем сейчас.
Но оно и так понятно, что когда-то возможно будет достигнут предел и открытий почти не будет происходить.
Ну и что с того??
От этого земля не остановится, электричество не пропадёт, процессоры не исчезнут. Всё будет просто по старому.
Как по мне, то обычный объективный факт попытались представить в сенсационном свете.
