Technology

Technology I INTRODUCTION
Technology, purposeful human activity which involves designing and making products as diverse as clothing, foods, artefacts, machines, structures, electronic devices and computer systems, collectively often referred to as “the made world”. Technology can also mean the special kind of knowledge which technologists use when solving practical problems (for example, designing and building an irrigation system for tropical agriculture). Such work often begins with a human want (for example, better safety for an infant passenger in a car) or an aspiration (for example, to see the inside of a human artery or to land on the Moon), and technologists draw on resources of many kinds including visual imagination, technical skills, tools, and scientific and other branches of knowledge. Technological activity is as old as human history and its impact on almost all aspects of people's lives has been profound. II DESIGN
A common feature of technological activity, no matter what outcome is in mind, is the ability to design. In common with technology, design is difficult to define briefly although the general statement that it is “the exercise of imagination in the specification of form” captures much of what is involved.
The aim of design is to give some form, pattern, structure, or arrangement to an intended technological product so that it is an integrated and balanced whole which will do what is intended. Designing often begins with an idea in a person's mind and the designer has to be able to envisage situations, transformations, and outcomes, and model these in the mind's eye. In the 19th century James Nasmyth, when describing how he had invented his steam pile driver, said that the machine “was in my mind's eye long before I saw it in action”; he could “build up in the mind mechanical structures and set them to work in imagination”. Much of this thinking is non-verbal and visual; it also involves creativity, including the ability to put together ideas in new ways. Sometimes this is a solitary activity, and was often thus in the past, but many designers today work in teams where discussion, sketches, and other visual representations, as well as analogies and ideas plucked from apparently unconnected fields, can all help the process.
One problem which designers face is that the requirements that a product has to fulfil are not always compatible: ease of maintenance, for example, may conflict with cost and aesthetic appearance; safety considerations may not be reconciled easily with completion of the work by the deadline; and materials chosen on technical grounds for their suitability may raise concerns on environmental or moral grounds (for example, waste disposal difficulties; production by unacceptable methods such as exploited labour). Compromise and optimization are necessary when designing.
Designing is sometimes represented as a linear or a looped set of processes—starting with identification of a problem or requirement, followed by generation of ideas for solutions; selection of a promising design option is then detailed, made, and finally evaluated. In reality the processes are almost always less orderly than this. Experience from making, for instance, can feed back and lead to modifications in the design. Also, evaluation is an on-going process throughout the stages. It is also the case that the processes of designing can differ according to the product involved. For example, designing active matrix liquid crystal displays, involving the use of basic scientific research, is different from designing corkscrews or mousetraps. Similarly, designing for manufacture on a large scale may require modifications to an artefact that was designed for use, but only as a one-off product. III TECHNOLOGY AND SCIENCE
Although technology and science have many features in common—not least in the minds of many people who link them together when viewed as present-day bodies of practice—their goals and how they judge success tend to differ.
In its most basic form, science is driven by curiosity and speculation about the natural world without thought of any immediate application. It aims to produce theories which can be tested experimentally in the public domain and which are valued according to criteria such as simplicity, elegance, comprehensiveness, and range of explanatory power. By no means all that goes on under the name of science has this “blue-sky”, unconstrained quality; so-called strategic science, for example, is focused more on yielding knowledge that might assist the subsequent development of, as yet unidentified, winning products and processes in the market-place.
Technology, on the other hand, has the goal of creating and improving artefacts and systems to satisfy human wants or aspirations. Success is judged in terms of considerations such as efficiency of performance, reliability, durability, cost of production, ecological impact, and end-of-life disposability. It has sometimes been said that whereas the output from science is a published paper for all to read and criticize, that from technology is a patent conferring sole ownership of the invention on the holder.
For many centuries technological advances of great significance were made without benefit of knowledge from science. The notable achievements of Asian technology by the end of the first millennium AD in fields such as iron production, printing, and hydraulic engineering, including dams, canals, and irrigation systems, are well documented. In southern Asia, at a later period, the high quality of Indian textile products, especially painted and printed cotton goods, set standards which were an incentive to technological developments in Britain.
Water wheels, canal locks, barbed wire (without which the American West could not have been opened up), food preservation, fermentation and many metallurgical processes are other instances where technology ran ahead of science. The relationship underwent change especially in the late 19th century with the growth of the chemical and electrical power industries; in these, scientific knowledge was of direct use in the solving of problems and the development of products, although it was rarely sufficient on its own. At a later date the communications and electronics industries provided further testimony to the effectiveness of a closer relationship between science and technology, as indeed did the experience of World War II and subsequent more local military conflicts.
By the second half of the 20th century, much modern technology was intimately related to scientific knowledge, and science itself had become increasingly linked to technology through its dependence upon complex instrumentation to explore the natural world. A technological innovation such as nuclear magnetic resonance imaging, a diagnostic technique widely used in medicine, could not have been developed without scientific knowledge of the magnetic properties of atomic nuclei. The symbiotic and synergistic relationship between modern technology and modern science has led some to use the term technoscience to describe what they see as now an essentially merged, even hybrid, enterprise.
Whether merged or not today, in the past science and technology have often followed independent paths. Furthermore, in so far as any relationship was acknowledged, it was most frequently seen as hierarchical, with technology practice trailing dependently in the wake of scientific theory. This notion that technology was merely applied science enjoyed wide currency in Euro-American circles, and beyond, throughout much of the 19th and 20th centuries. Today there would be little support for it. A more widely accepted model of the relationship is that of two different but interdependent communities of practice which overlap and intermesh in their activities. However, the scientific knowledge constructed by scientists in their search for understanding of natural phenomena is not always in a form which enables it to be used directly and effectively in technological tasks. It often has to be reworked and translated into a form which relates better to the design parameters involved. IV HISTORICAL PERSPECTIVES
Historical accounts of technology can be constructed from many different perspectives, each of which may help in the understanding of this complex enterprise.
At the most general level, attempts have been made to discern and characterize distinctive periods in the evolution of technology. Writing in the 1930s, the Spanish philosopher José Ortega y Gasset identified three. In the first and longest period, there were no systematic techniques for the discovery and development of technological devices. The earliest toolmakers' achievements such as stone axes, scrapers, and control of fire were no more than the products of chance. In the second period, certain technological skills had become sufficiently conscious to be passed from one generation to the next by accomplished practitioners. These craftsmen, however, had no systematic body of knowledge about their devices. Possession of this kind of knowledge, resulting from analytical modes of thought associated with modern science, characterized the third period and empowered people—in a radically different way from previously—to realize their technological goals.
Also in the 1930s, Lewis Mumford published his classic work Technics and Civilization, including an analysis of the last 1,000 years of the development of technology in terms of three successive, but overlapping and interpenetrating, phases. The first, “eotechnic” phase (roughly ad 1000 to 1750) was characterized by raw materials such as wood, glass, and water, with increased use of horse power and energy from wind and water. This was followed by a “palaeotechnic” phase (roughly 1750 to 1900) a period of “carboniferous capitalism” characterized by a coal and iron complex and the steam engine. Beyond this came a “neotechnic” phase, with science prominent and an electricity-alloy complex with new materials such as plastics coming into use. Electrical energy and diesel and petrol combustion engines replaced the steam engine.
Despite similarities, both of these analyses fail to reflect the impact of technology or the technological characteristics of the late 20th century. Achievements here include new fabrication resources, including composites and “smart” materials which can respond to changes around them and behave as if possessing a memory. Technology has extended into the realm of the living with, for example, genetically engineered strains of “improved” plants and animals. Nuclear power is an alternative, if controversial, energy source. Dramatically enhanced means of communication and information processing are widely available and there has been a substantial growth of complex socio-technical systems relating to almost every aspect of work and everyday life—such as the ones encountered at the supermarket checkout or when buying a flight ticket.
The scale of these technological innovations and the speed of their implementation are quite different from anything experienced in previous phases of the evolution of technology. At the same time a distinguishing feature of the age has been a growing awareness of negative aspects of technology. Technological disasters of unprecedented magnitude have occurred and been widely publicized: the list is long and includes spillages from giant oil tankers; the 1984 tragedy at Bhopal, India, when an explosion at the Union Carbide chemicals plant led to the escape of methyl isocyanate and the death of over 3,000 people, the worst industrial accident to date; the 1986 space shuttle Challenger disaster, when the spacecraft exploded just after the launch killing seven astronauts; and also in 1986, the Chernobyl disaster when a fire in the core of a Soviet nuclear reactor at Chernobyl' in Ukraine resulted in 31 deaths and the spewing out of deposits of radioactive debris, which fell on many regions of the world—the world's worst nuclear industry accident.
The United Nations Conference on Environment and Development—widely known as the Earth Summit, held in Rio de Janeiro in 1992—brought into prominence issues such as climatic change, sustainable development, and the more responsible management of global resources, with particular regard to environmental pollution, waste disposal, and a reduction in the gap in technological capacity between developed and developing countries. In this spectacular new phase, as the 20th century closes, any characterization of technology would be incomplete if it failed to acknowledge its inescapable moral dimension. Perhaps no other technological developments have more vividly brought home this realization than those in the field of atomic energy since the dropping of two atomic bombs on the Japanese cities of Hiroshima and Nagasaki in 1945. As Robert Oppenheimer, scientific leader of the Manhattan Project which produced the original bombs, later remarked: “the physicists have known sin, and this is a knowledge which they cannot lose”.
Less comprehensive historical studies have shed further light on the nature and development of technology. A broad distinction can be drawn between so-called internalist and contextualist accounts. In the internalist description the focus is predominantly on the design features of the particular devices and on related matters such as the nature of technical improvements and the stimulus provided to other inventions. Medieval fortifications, ploughs and ploughshares, keyboard mechanisms, clocks, steel cantilever bridges, chain mail, steam engines, space rockets, and the mariner's compass have been, and are typical, subjects for internalist histories. Informative though these are, such accounts tend to provide little in the way of explanation of why artefacts have taken the form they did and why mutations in those artefacts have occurred.
In contrast, contextualist accounts place emphasis on the cultural factors which have influenced, and have been influenced by, technological developments. The economic, social, and political ambience in which the technological activity took place and in which it assumed its particular form becomes the focus of historical investigation.
Other external factors, for example geographical, legal, and environmental constraints, may also affect the shaping of technology and, in turn, contribute to a view of technology as itself an influence on the cultural context. For example, the study of the consequences for workers in the machine-tool industry of a technological development such as automation has served to locate technology in a political context and to highlight questions about the identity and motives of the social and managerial groups who took decisions about the particular form which the technology should assume.
A premise here is that there is nothing inevitable about any technological development. It could always have been different; other options were available. The technology we encounter is the result of decisions which reflect the value judgements of those who were in a position to shape the technology. It would seem that form not only follows function, but power as well. V CONTROL OF TECHNOLOGY
The extent to which technology is under human control is an important question, the answer to which has profound implications for how people perceive technology. On the one hand, there are the social constructionists who believe that technology is a tool shaped by the bidding of its creators or, at least, that it is social groups who define and give meaning to artefacts. A motor car is, after all, not just a means of transport: it can be a status symbol, a reflection of self-image, a source of Treasury revenue, a criminal's machine for ram-raiding, a competitor to rail travel provisions, the basis for a manufacturing or service job, and much more besides. On the other hand there is the view that, once launched, technology assumes a life of its own as an autonomous agent of change, driving history. Far from being society's servant, technology is society's master, increasingly shaping our destinies in ways which seem inevitable and irreversible. According to believers in this technological determinism, we are progressively being manoeuvred into ways of acting, both in the home and in employment, which are not of our deliberate choosing, but which are dictated by the technologies we have created. Instead of our values shaping technology, technology is shaping our values. The motor car was not invented to support out-of-town shopping and the depopulation of city centres; air pollution by exhaust emissions was not a planned outcome; the sacrificing of tracts of countryside and areas of natural beauty for additional roads to reduce traffic congestion was never intended by the pioneer manufacturers; nor was the association of fast cars with crime.
Between the poles of social constructivism and technological determinism there are intermediate positions for which historical evidence lends some support. Large, complex technological systems seem capable of developing a momentum of their own and technologies can display latent inclinations that predispose people to develop certain lifestyles rather than others. Fortunately, neither momentum nor inclination is irresistible. An example is the development of anti-pollution technology, with legislation to support it, in the case of the motor car. What does appear to be the case, however, is that technology is not only a moral activity, but a political one as well. The exercise of technological choice requires democratic political institutions where the effects and possible impacts of technological change can be openly addressed and their compatibility with personal and society's goals assessed. VI WOMEN AND TECHNOLOGY
A remarkable feature of the history of technological development, at least as it has been written until comparatively recently, is the invisibility of women. The view that there have been few women technologists is deeply rooted and has been periodically reinforced by heroic accounts of, for example, the great road-makers, fen-drainers, canal and bridge builders, and lighthouse constructors in books such as Samuel Smiles' Men of Invention and Industry (1884).
Yet women have been growers, gatherers, and processors and storers of food from, and even before, the beginning of recorded history. In some countries their responsibilities in this respect remain unchanged today. Similarly, in many societies the activities of infant and child care, nursing, water and wood (if not child) carrying, and spinning and weaving traditionally have been, and often still are, seen as women's work. Historically, they have, worldwide, had a key role as healers and as sources of knowledge and practice relating to contraception, the premature termination of pregnancies, and the easing of labour, childbirth, and menstrual experiences. In short, women have always lived in close association with certain technologies. It has been claimed that they were responsible for some early technological innovations such as the digging stick (possibly the first lever) and the rotary quern (a hand-operated grain mill) as the world's first crank. The designers of other artefacts such as cradles, the baby bottle, buttons and button holes, and slings that permit agricultural work while carrying an infant remain anonymous, but the probability is strong that they originated with women.
More recently, studies of the technological capabilities of girls and women in countries including the Sudan, Sri Lanka, Zimbabwe, Nigeria, and the Democratic Republic of the Congo have demonstrated the extent of their ingenuity in matters of food preparation, often in the face of great adversity. To give just one example, when the Tonga tribe was transplanted from north-western Zimbabwe to Matabeleland North Province (to allow the flooding of the valley of the Zambezi River for the Kariba hydroelectric scheme), it moved from rich alluvial soils to an area of poor soils with low rainfall, where hunting was prohibited. Because it was difficult to grow enough food, the women innovated and adapted food production and processing techniques to supplement family diets. New sources of food were identified from indigenous plants and trees, and new processes were developed for preparing food and rendering it fit for storage.
In industrialized societies recent research has provided evidence of women's previously unacknowledged contributions to technological developments. Examples include the cotton gin, the sewing machine, the small electric motor, the McCormick reaper, the printing press, and the Jacquard loom. Also, it is clear that women were rarely passive recipients of technology, but, as its users, could interact in ways which fed back into and influenced the design of artefacts and systems. The work experiences of women telephonists in the first exchanges were contributory to the development of future telephone networks.
There are no simple explanations for the invisibility of women in the history of technology. Possibly men, who wrote the histories, simply did not know what women did. In some societies the roles were very precisely laid down: “Men's work is to hunt and fish and then sit down; women's work is all else”. For many years the inability of a woman to patent an invention in her own name was clearly an obstacle to recognition. The need for capital to support a period of trial and development of a novel artefact was another barrier. It was only in 1882, when the Married Women's Property Act was passed, that British women acquired legal possession and control of personal property independently of their husbands. The dominant role of warfare and military concerns in the development of technology has also been suggested as contributory to women's absence from the pages of its history.
There may, however, be considerations of a different kind to take into account. It has been argued that the ways in which women value things and people and communicate with others are different from those of men. As a generalization, women are reputed to be less adversarial, more given to networking and generally less formal and hierarchical relationships, and concerned to minimize disaster and confrontation, as opposed to the authoritarian, rule-bound, competitive, and hierarchical structures of the world of men, intent on maximizing gain.
Even if these differences are more the product of socially determined roles than innate propensities, it would seem that the greater involvement of women in technology could lead to a wider definition of what counts as technological, and to possibly different solutions to what are deemed technological problems. VII TECHNOLOGY AND CULTURE
Culture is often taken to mean the norms, values, beliefs, and conventions of a group. Members interpret their experiences in terms of these shared values and categories and so can be distinguished from members of other groups. An example is the way in which different beliefs about the origin of human life, about the relationship of humans to the natural world, and about death are held by different religious groups such as Buddhists, Christians, and Confucians.
Following from this it is suggested that technologies which originate in a particular cultural context bear the imprint of that culture. They will reflect characteristic values and beliefs as do, for example, the pyramids of Egypt, the Gothic cathedrals of medieval Europe, and the mosques of the Islamic world in their structure, configuration, and decoration. From the present day, Kenji Ekuan, designer of Yamaha motorcycles and musical instruments, has argued that Japanese design is characterized by “complex simplicity”: the products are small and precision built, lightweight yet robust, energy-frugal, and miniaturized with quality—all attributes which he regards as expressions of Japanese culture. French couture and cuisine is a further example where technological products are commonly regarded as expressions of cultural values and norms. Indeed, the definition of culture might be extended to include technology as a part of culture rather than a product of it; that is, culture comprises artefacts and technical processes as well as values and beliefs. A Technology Transfer
One striking way of bringing into relief the values embedded in technologies is by their transfer from one cultural context to another. When, in the 19th century, agricultural settlers began to invade the Canadian plains on which Indians hunted buffalo—the mainstay of their life—the Indian response was well captured in the following quotation:

You ask me to plough the ground. Shall I take a knife and tear my mother's breast? Then, when I die she will not take me to her bosom to rest ... You ask me to cut grass and make hay and sell it and be rich like white men, but how dare I cut off my mother's hair?
T. C. McLuhan, Touch the Earth: A Self-Portrait of Indian Existence
The attempt to persuade the Plains Indians to adopt the agricultural practices of ploughing, planting, and harvesting brought into conflict two contrasting value systems regarding the relationship of humans to their environment. The traditional Indian way of life involved respect for, and harmony with, nature and with the spiritual powers believed to inhabit all living and non-living things. The impact of agricultural technology as brought by the predominantly European homesteaders resulted in confusion, strain, and often the destruction of the Indian lifestyle.
Not all technology transfers have had the same disastrous consequences for the recipient culture, although there are many instances where the adoption of a new technology has caused major changes in employment patterns and social structures. Change in the means of manufacturing sandals in North Africa is a case in point. In one region the sandals were made by some 5,000 artisan shoemakers, using local supplies of leather, glue, thread, hand tools, tacks, wax and polish, fabric linings, laces, wooden lasts, and card boxes. Then, two Swiss plastic-injection moulding machines for the manufacture of sandals were introduced, each in operation for three shifts per day and requiring a labour force of only 40 workers. A million and a half pairs of sandals per year were produced, selling at less than the cost of the leather sandals and with a longer life. As a result, many indigenous small industries declined, as did employment opportunities; there was an increase in dependency on imported plastic, spare parts for the machines, and maintenance services—all requiring foreign currency. An accompanying increase in migration from rural areas to cities contributed to the creation of a “dual society”.
Such experiences of transfer testify to the non-neutrality of technologies and the way in which they can recreate, in a new host culture, aspects of the social system of their place of origin. For this reason, technology has sometimes been likened to a social gene which can carry encoded social relations from one context to another and replicate them there. When Japan was modernized after the Meiji Restoration in 1868 and deliberately recruited science and technology experts from already industrialized countries, it sought actively to avoid the introduction of foreign values with the technologies it imported. The cry was for “Western techniques but Eastern values”; the assimilation of new technologies was carefully managed to ensure their alliance to an intense patriotism and to the growth of the nation's industrial and military strength.
Although one-way technology transfer can act as a powerful alternative to military colonization and a means of fostering the long-term dependency of the recipient culture on the provider of the technology, the transfer process is often more complex and interactive. For one thing, technologies are not used by every culture in exactly the same way. Gunpowder, invented by the Chinese and used by them for fireworks and primitive guns, when brought to Europe stimulated the production of much more powerful and devastating cannon.
Nearer the present day, a project undertaken by the United Nations Children's Fund (UNICEF) to bring a supply of drinkable water to rural villages in India began by using cast-iron copies of farmstead pumps from the United States and Europe. While adequate for a single household, these were not designed to withstand continual daily use by an entire village community. Breakdowns were frequent. As a result, attempts were made to design a more reliable pump appropriate to the particular demands of village use. The stringent design criteria included low cost, durability, easy installation, maintenance and repair, and ability to be mass-produced under Indian conditions. However, the production of such a pump by no means solved the problem. There was also need for a supporting infrastructure of warehouses for spare parts, distribution networks for delivery of supplies, and training programmes for those who would monitor the quality of the water supply and keep the pump in good working order. Progressive decentralization of responsibility for the technology, from government and international agencies to local manufacturers and suppliers, was needed and a system of quality control involving the standardization of pump parts brought into being. Only by the well-synchronized functioning of all components of the system, in which the pump as artefact was itself enmeshed, was the technology likely to be successful. The drilling of water boreholes and the construction of appropriate pumps represented only one component of the total challenge of transfer. B Appropriate Technology
The idea of a technology being appropriate in the sense of respecting the needs, resources, environment, and lifestyles of the people using it came into prominence in the 1960s. A powerful advocate was the economist E. F. Schumacher, who in his book Small is Beautiful (1973), wrote of “technology with a human face” and used the term “intermediate technology”. Schumacher drew on the belief of Gandhi that the poor of the world cannot be helped by mass production, only by production by the masses. His prescription for intermediate technology required it to make use of the best of modern knowledge and experience; be conducive to decentralization; be compatible with the laws of ecology; be gentle in its use of scarce resources; and serve humans instead of making them the servants of machines. However, not all those in the so-called developing world are content to see the cultivation of appropriate technology in their own countries while the industrialized societies are perceived as speeding towards a different and high-technology future. VIII TECHNOLOGY AND SOCIETY
It is clear that technology's impact on society has been profound, and never more so than today. For many, including governments, its ability to contribute to wealth generation and economic development makes its encouragement a national priority. In the United Kingdom, a government White Paper published in 1986 asserted that “Survival and success will depend on designing, making, and selling goods and services that the customer wants at the time he wants and at a price he is prepared to pay; innovating to improve quality and efficiency; and maintaining an edge over all competition”.
Subsequently, a Technology Foresight Programme was begun to identify ways in which government resources might best be directed in the interests of the economy and to indicate areas of technology which might yield productive innovations. A series of technology foresight themes was drawn up under headings such as harnessing bio processes, materials synthesis and processing, computing and communications, cleaner world, modelling and impact, and control in management, the latter including security and anti-fraud technology.
Clearly, technology is seen as having a major role to play in improving the nation's economic competitiveness and quality of life. Similar dispositions towards, and expectations of, technology are to be found in many other countries.
The idea that the artefacts of technology are indices of progress is deeply entrenched in many societies. For most of the industrialized world a return to a situation without electricity and water services, telephones and televisions, refrigerators, washing-machines, cars, trains, aeroplanes, and sewage and waste disposal systems would be widely considered to be utterly retrograde. Equally, the vision of progress for many in poorer countries has been in terms of what, technologically, others have but they have not yet got. Either way, however, what is sometimes forgotten is that technology can lead a double life; it may conform to the intentions of its creators, but it can also yield unintended, sometimes unimagined, outcomes. Even with a clear vision of what type of society is being sought, technology can be an unpredictable ally. It also has the ability to usurp, or divert attention from, consideration of the outcome, the onward quest for technological development itself becoming the goal.
With the increased use of technology in production and service industries, a concern has grown that jobs will be destroyed and a vast army of unemployed will result. It is true that, over the past 200 years, many millions of manual workers have been replaced by machines, most dramatically, perhaps, in agriculture. Nearer the present, much factory work has also been automated. Machines saved on labour costs while increasing production, and were thus welcomed by factory owners. However, expansion of the service sector has provided alternative employment for many. Now, with the growing automation of service jobs, and technological developments such as computer diagnosis of illnesses, which put even the skilled at risk of redundancy, concerns have heightened about unemployment. Recent studies, however, provide little support for the view that technological change is the sole cause of unemployment. Rather, it is possible that technology can create more jobs than it destroys. However, a clear picture may be difficult to obtain for some time because firms take time to learn how to use new technology effectively and replace obsolete management structures. Nevertheless, jobs such as programmer, systems analyst, network manager, database architect, computer operator, and computer repair technician were unheard of only a short time ago and are now among the fastest growing. It does not follow, however, that those displaced from, for example, middle management and from lower-skilled jobs will necessarily be able to move quickly into the new growth areas of employment, or whether these latter will provide a sufficient number of jobs for a nation's workforce.
It is frequently claimed that the most potent agent of change on present-day society and the economy will prove to be information technology. The so-called digital revolution whereby information—whether text, sound, or video—can be converted into, and from, binary digits (bits) and transmitted over global networks is believed to be likely to transform industries such as banking, telecommunications, and publishing. Advances in light-wave communications technology based on optical fibres have vastly increased the volume and speed of information transmission. The development of flat-panel displays has allowed the computer mobility from the desk. Together these have contributed to the integration of computer and communications technology which, for the user, transcends space and makes information available on demand.
As well as rich opportunities, such a major social change presents severe challenges. One is how to avoid the creation of a divided society of information “haves” and “have nots”. This is both a national and an international problem. Others relate to ownership and security of information: cyberspace is a new frontier where existing legal principles and practice are having to be rethought. Yet again, there are moral issues to be faced about the kinds of information which should be openly available to users of the Internet.
It is understandable, given the complex ways in which technology interacts with society and with the lives of individuals, that perceptions of it should be widely divergent and influenced strongly by the nature of personal experiences. Technophobes with respect to military technology may be technophiles when it comes to medical technology. In general, public understanding of the nature of technology is not well developed, and there is widespread recognition, globally, of the need for a greater degree of “technological literacy” among citizens. The inclusion of technology as a subject in the curriculum of general education of both primary and secondary schoolchildren is a recent development in many countries intended to improve the understanding and the practice of technology.
