Consider two tools, one is a stone tool, an Acheulian axe, that has been around for at least a million years. Another is a communication tool, an iPhone, which has been around for about 5 years. Both tools have similarities – they are hand sized, fit in our palm perfectly, and are considered among the most important technologies of their days. The differences are more dramatic. The axe is made of stone and can be used for shaping, cutting, and hunting. The phone is an elaborate combination of plastics, metals, silicon and sophisticated software that allows us to take and share pictures and videos, communicate in real time, listen to music, transfer money and purchase products, check weather forecasts, play games, send texts, and place international phone calls. The possibilities of a smartphone are endless.
How did we achieve such progress? Not easily. According to Matt Ridley, the author of “The Rational Optimist”, the stone tool was the only technology for more than a thousand millennia and the bodies and brains of prehistoric men changed faster than their tools. Only later in our history did people begin developing newer and better technologies such as the fishing rod, the wheel and agricultural tools. The rate of invention has accelerated rapidly during the past two centuries.
The development of communication technologies was central to this change. For centuries the fastest way to deliver information was on a horseback. Still, people would wait for their mail for days, weeks and even months. The materials needed for such information dissemination were scarce too: horses were expensive, paper and ink were not readily available for everyone, and people overall had less than desired literacy levels.
The invention of Gutenberg printing press changed the way information was produced, however the dissemination of information was still relatively slow. The optical telegraph was invented in France in the 18th century. Multiple towers were built around the country. Messages were delivered by conveying visual signals: a sender would send the message; a recipient of the next tower would get the message while looking at a telescope and transfer it to a person sitting on the top of another tower and so on. On a good clear day, a message could reach from Paris to the South of France in one day, on a gloomy day it would take longer. The quality of messages was below optimal as a lot of errors were made along the way. Soon enough, optical telegraphs were replaced with electric telegraphs, and the first transatlantic message was sent in the 19th century. After that, the speed of transmitting information became faster and cheaper almost every decade. The radio, telephones, television and finally the Internet lowered the cost of communication, and made information fast and pervasive. Later, mobile technologies connected people around the world including countries that previously did not have even land lines. Faster means of communication allowed people to share ideas more easily, further accelerating the rate of technological innovation.
Ridley explores the notion of “collective intelligence” as a driver of innovation. The stone tool required the creativity and skills of one person and was made of one material – the rock. The smartphone tool needs the creativity and skills of thousands of people. Phones are made mainly of plastics, metals, ceramics and glass. To produce these materials copper, gold, lead, nickel, zinc, beryllium, tantalum, lithium, cadmium, crude oil, limestone and various liquid crystalline substances are required. These materials are mined, combined with other materials in a processing plant and shipped to the manufacturer. Software developers write various applications using computers and servers that are produced by others who use a range of materials in their work. Nano technologists, quantum physicists, inventors, entrepreneurs, marketers, advertisers and countless other people contribute to the creation of a single device.
Natural curiosity forces us to come up with better communication solutions and the advancements in communication technologies has allowed us to use our minds collectively to produce a wider range of goods. With advancements in technology we are able to create elaborate and complicated tools in a short period of time because we draw upon the knowledge of multiple people. Although no one person can recreate these tools on her own due to their complexity, the collective knowledge generated by people enables creativity and innovation. Non-experts with great ideas now find it easier to collaborate with experienced specialists, and to contribute greatly to the emergence of new technologies that may enrich people’s lives, while helping us progress even further from the Acheulian axe.
