23 Things They Don't Tell You About Capitalism

Compared to the changes brought about by the washing machine (and company), the impact of the internet, which many think has totally changed the world, has not been as fundamental – at least so far. The internet has, of course, transformed the way people spend their out-of-work hours – surfing the net, chatting with friends on Facebook, talking to them on Skype, playing electronic games with someone who’s sitting 5,000 miles away, and what not. It has also vastly improved the efficiency with which we can find information about our insurance policies, holidays, restaurants, and increasingly even the price of broccoli and shampoo.

However, when it comes to production processes, it is not clear whether the impacts have been so revolutionary. To be sure, for some, the internet has profoundly changed the way in which they work. I know that by experience. Thanks to the internet, I have been able to write a whole book with my friend and sometime co-author, Professor Ilene Grabel, who teaches in Denver, Colorado, with only one face-to-face meeting and one or two phone calls.[5] However, for many other people, the internet has not had much impact on productivity. Studies have struggled to find the positive impact of the internet on overall productivity – as Robert Solow, the Nobel laureate economist, put it, ‘the evidence is everywhere but in numbers’.

You may think that my comparison is unfair. The household appliances that I mention have had at least a few decades, sometimes a century, to work their magic, whereas the internet is barely two decades old. This is partly true. As the distinguished historian of science, David Edgerton, said in his fascinating book The Shock of the Old – Technology and Global History Since 1900, the maximum use of a technology, and thus the maximum impact, is often achieved decades after the invention of the technology. But even in terms of its immediate impact, I doubt whether the internet is the revolutionary technology that many of us think it is.

The internet is beaten by the telegraph

Just before the start of the trans-Atlantic wired telegraph service in 1866, it took about three weeks to send a message to the other side of the ‘pond’ – the time it took to cross the Atlantic by sail ships. Even going ‘express’ on a steamship (which did not become prevalent until the 1890s), you had to allow two weeks (the record crossings of the time were eight to nine days).

With the telegraph, the transmission time for, say, a 300-word message was reduced to 7 or 8 minutes. It could even be quicker still. The New York Timesreported on 4 December 1861 that Abraham Lincoln’s State of the Union address of 7,578 words was transmitted from Washington, DC to the rest of the country in 92 minutes, giving an average of 82 words per minute, which would have allowed you to send the 300-word message in less than 4 minutes. But that was a record, and the average was more like 40 words per minute, giving us 7.5 minutes for a 300-word message. A reduction from 2 weeks to 7.5 minutes is by a factor of over 2,500 times.

The internet reduced the transmission time of a 300-word message from 10 seconds on the fax machine to, say, 2 seconds, but this is only a reduction by a factor of 5. The speed reduction by the internet is greater when it comes to longer messages – it can send in 10 seconds (considering that it has to be loaded), say, a 30,000-word document, which would have taken more than 16 minutes (or 1,000 seconds) on the fax machine, giving us an acceleration in transmission speed of 100 times. But compare that to the 2,500-time reduction achieved by the telegraph.

The internet obviously has other revolutionary features. It allows us to send pictures at high speed (something that even telegraph or fax could not do and thus relied on physical transportation). It can be accessed in many places, not just in post offices. Most importantly, using it, we can search for particular information we want from a vast number of sources. However, in terms of sheer acceleration in speed, it is nowhere near as revolutionary as the humble wired (not even wireless) telegraphy.

We vastly overestimate the impacts of the internet only because it is affecting us now. It is not just us. Human beings tend to be fascinated by the newest and the most visible technologies. Already in 1944, George Orwell criticized people who got over-excited by the ‘abolition of distance’ and the ‘disappearance of frontiers’ thanks to the aeroplane and the radio.

Putting changes into perspective

Who cares if people think wrongly that the internet has had more important impacts than telegraphy or the washing machine? Why does it matter that people are more impressed by the most recent changes?
