By the mid 20th century humans had achieved a level of technological mastery sufficient to leave the surface of the planet for the first time and explore space.

Technology is a word with origins in the Greek word technologia (τεχνολογία), techne (τέχνη) "craft" and logia (λογία) "saying." It is a broad term dealing with the use and knowledge of humanity's tools and crafts.

[edit] Definitions

[edit] Usage

It is difficult to obtain precise definition of technology. According to the involved science fields and engineering domain where it is developed, there are many kinds of technologies. Generally, the following distinctions can be made:

  • Science is the formal process of investigating natural phenomena. It produces information and knowledge about the world.
  • Engineering is the goal-oriented process of designing and building tools and systems to exploit natural phenomena for a practical human means. Engineers work within the constraints of natural laws and societal needs to create technology.
  • Technology is the consequence of these two processes and societal requests. Most commonly, the term technology is used as the name of all engineering products.

For scientists and engineers, technologies are: conceptual tools - as methods, methodologies, techniques; instruments - as machines, aparatus, software programs; as well as, different artificial materials which they normally use.

Technologies are not direct products of science, because they have to satisfy such requirements as: utility, usability and safety, therefore the application of the scientific knowledge to concrete purposes requires the contribution of engineering research.

Until recently, it was believed that the development of technology was a concept akin and restricted only to human beings, but recent studies show that other primates (such as chimpanzees), and certain dolphin communities, have developed simple tools and learned to pass this knowledge to other generations, what would constitute a form of non-human technological development. <ref>http://www.mc.maricopa.edu/dept/d10/asb//anthro2003/origins/hominid_journey/optional3.html Chimpanzee Tool Use and More</ref> <ref>http://news.bbc.co.uk/2/hi/science/nature/4613709.stm BBC News: Sponging dolphins learn from mum</ref>

[edit] Bernard Stiegler on technology

The philosopher Bernard Stiegler, in Technics and Time, 1: The Fault of Epimetheus, understands technology as "organized inorganic matter", and as "the pursuit of life by means other than life."<ref>Bernard Stiegler, Technics and Time, 1: The Fault of Epimetheus (Stanford: Stanford University Press, 1998), p. 17 and p. 49.</ref> As such, the advent of technology represents a moment in the history of the exteriorization of existence. In formulating an understanding of technology in these terms, Stiegler draws especially on the work of André Leroi-Gourhan and Gilbert Simondon.

For human beings this does not only mean that it is possible to learn how to use tools from one's parents, but that the past is in general inscribed in objects and remains. Whether purposely or incidentally, every manufactured object is therefore a means of transmitting knowledge, a third kind of memory in addition to genetic memory and individual nervous system memory. Thus an archeologist can learn from the discovery of a primitive tool about the life of the person whose gesture is inscribed in the flint from which it is fashioned. As Stiegler puts it, "humans die but their histories remain."<ref>http://culturemachine.tees.ac.uk/Cmach/Backissues/j005/Articles/Stiegler.htm Our Ailing Educational Institutions</ref> According to Stiegler this interrupts the ordinary processes of natural selection, and it is therefore no more true to say that humans invented technology than it is to say that technology invented humanity.

The history of Technology is at least as old as humanity. Some primitive forms of tools have been discovered with almost every find of ancient human remains dating from the time off. The history of technology follows a progression from simple tools and simple (mostly human) energy sources to complex high-technology tools and energy sources.

The earliest technologies converted readily occurring natural resources (such as rock, wood and other vegetation, bone and other animal byproducts) into simple tools. Processes such as carving, chipping, scraping, weaving, knotting, rolling (the wheel), and sun-baking are simple means for the conversion of raw materials into usable products. Anthropologists have uncovered many early human habitations and tools made from natural resources. Birds and other animals often build elaborate nests and some simple tools out of various materials. We normally don't consider them to be performing a technological feat, primarily because such behavior is largely instinctive. There is some evidence of occasional cultural transferrence, especially among the other, nonhuman primates. Nevertheless, there is now considerable evidence of such simple technology among animals other than humans.

The use, and then mastery, of fire (circa 1,000,000 - 500,000 BC [1]) was a turning point in the technological evolution of humankind, affording a simple energy source with many profound uses. Perhaps the first use of fire beyond providing heat was the preparation of food. This enabled a significant increase in the vegetable and animal sources of food, while greatly reducing perishability.

The use of fire extended the capability for the treatment of natural resources and allowed the use of natural resources that require heat to be useful. (The oldest projectile found is a wooden spear with fire hardened point, circa 250,000 BC.) Wood and charcoal were among the first known materials used as a fuel. Wood, clay, and rock (such as limestone), were among the earliest materials shaped or treated by fire, for making artifacts such as weapons, pottery, bricks, and cement. Continuing improvements led to the furnace and bellows and provided the ability to smelt and forge native metals (naturally occurring in relatively pure form). Gold, copper, silver, and lead, were such early metals. The advantages of copper tools over stone, bone, and wooden tools were quickly apparent to early humans, and native copper was probably used from near the beginning of Neolithic times (about 8000 BCE). Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires.

Image:Wheel Iran.jpg
The wheel was invented circa 4000 BCE.
Eventually, the working of metals led to the discovery of alloys such as bronze and brass (about 4000 BCE). The first uses of iron alloys such as steel dates to around 1400 BCE.

Meanwhile, humans were learning to harness other forms of energy. The earliest known use of wind power is the sailboat. The earliest record of a ship under sail is shown on an Egyptian pot dating back to 3200 BCE. From prehistoric times, Egyptians probably used "the power of the Nile" annual floods to irrigate their lands, gradually learning to regulate much of it through purposely built irrigation channels and 'catch' basins. Similarly, the early peoples of Mesopotamia, the Sumerians, learned to use the Tigris and Euphrates rivers for much the same purposes. But more extensive use of wind and water (and even human) power required another invention.

According to archaeologists, the wheel was invented about 4000 B.C. The wheel was likely independently invented in Mesopotamia (in present-day Iraq) as well. Estimates on when this may have occurred range from 5500 to 3000 B.C., with most experts putting it closer to 4000 B.C. The oldest artifacts with drawings that depict wheeled carts date from about 3000 B.C.; however, the wheel may have been in use for millennia before these drawings were made. There is also evidence from the same period of time that wheels were used for the production of pottery. (Note that the original potter's wheel was probably not a wheel, but rather an irregularly shaped slab of flat wood with a small hollowed or pierced area near the center and mounted on a peg driven into the earth. It would have been rotated by repeated tugs by the potter or his assistant.) More recently, the oldest-known wooden wheel in the world was found in the Ljubljana marshes of Slovenia.

The invention of the wheel revolutionized activities as disparate as transportation, war, and the production of pottery (for which it may have been first used). It didn't take long to discover that wheeled wagons could be used to carry heavy loads and fast (rotary) potters' wheels enabled early mass production of pottery. But it was the use of the wheel as a transformer of energy (through water wheels, windmills, and even treadmills) that revolutionized the application of nonhuman power sources.

Tools include both simple machines (such as the lever, the screw, and the pulley), and more complex machines (such as the clock, the engine, the electric generator and the electric motor, the computer, radio, and the Space Station, among many others).

As tools increase in complexity, so does the type of knowledge needed to support them. Complex modern machines require libraries of written technical manuals of collected information that has continually increased and improved -— their designers, builders, maintainers, and users often require the mastery of decades of sophisticated general and specific training. Moreover, these tools have become so complex that a comprehensive infrastructure of technical knowledge-based lesser tools, processes and practices (complex tools in themselves) exist to support them, including engineering, medicine, and computer science. Complex manufacturing and construction techniques and organizations are needed to construct and maintain them. Entire industries have arisen to support and develop succeeding generations of increasingly more complex tools.

[edit] Electronics

Image:Moore Law diagram (2004).png
Growth of transistor counts for Intel processors (dots) and Moore's Law (upper line=18 months; lower line=24 months)

Electronics have grown ever smaller and more sophisticated. Components have progressed from vacuum tubes, through transistors, to integrated circuits.

Moore's law is about the empirical observation, that at our rate of technological development, the complexity of an integrated circuit, with respect to minimum component cost, will double approximately every 18 months.

It is attributed to Gordon E. Moore,<ref>Not to be confused with another G.E. Moore, the philosopher George Edward Moore, the creator of Moore's paradox.</ref> a co-founder of Intel. However, Moore had heard Douglas Engelbart's similar observation possibly in 1965. Engelbart, a co-inventor of today's mechanical computer mouse, believed that the ongoing improvement of integrated circuits would eventually make interactive computing feasible.

The influence of computers has been pervasive in the workplace, radically changing the way people access and buy goods and services, process accounts, store information and communicate with others. The personal computer has enabled these activities to be commonplace in the home, and electronic technologies have allowed people to receive news and entertainment from all over the world into their homes.

[edit] Economics and technological development

Economics can be said to have arrived on the scene when the occasional, spontaneous exchange of goods and services began to occur on a less occasional, less spontaneous basis. It probably didn't take long for the maker of arrowheads to realize that he could probably do a lot better by concentrating on the making of arrowheads and barter for his other needs. Clearly, regardless of the goods and services bartered, some amount of technology was involved—if no more than in the making of shell and bead jewelry. Even the shaman's potions and sacred objects can be said to have involved some technology. So, from the very beginnings, technology can be said to have spurred the development of more elaborate economies.

In the modern world, superior technologies, resources, geography, and history give rise to robust economies; and in a well-functioning, robust economy, economic excess naturally flows into greater use of technology. Moreover, because technology is such an inseparable part of human society, especially in its economic aspects, funding sources for (new) technological endeavors are virtually illimitable. However, while in the beginning, technological investment involved little more than the time, efforts, and skills of one or a few men, today, such investment may involve the collective labor and skills of many millions.

[edit] Funding

Consequently, the sources of funding for large technological efforts have dramatically narrowed, since few have ready access to the collective labor of a whole society, or even a large part. It is conventional to divide up funding sources into governmental (involving whole, or nearly whole, social enterprises) and private (involving more limited, but generally more sharply focused) business or individual enterprises.

The government is a major contributor to the development of new technology in many ways. In the United States alone, many government agencies specifically invest billions of dollars in new technology.

[In 1980, the UK government invested just over 6 million pounds in a four-year programme, later extended to six years, called the Microelectronics Education Programme (MEP), which was intended to give every school in Britain at least one computer, microprocessor training materials and software, and extensive teacher training. Similar programmes have been instituted by governments around the world.]

Technology has frequently been driven by the military, with many modern applications being developed for the military before being adapted for civilian use. However, this has always been a two-way flow, with industry often taking the lead in developing and adopting a technology which is only later adopted by the military.

Entire government agencies are specifically dedicated to research, such as America's National Science Foundation, the United Kingdom's scientific research institutes, America's Small Business Innovative Research effort. Many other government agencies dedicate a major portion of their budget to research and development.

[edit] Private funding

Research and development is one of the biggest areas of investments made by corporations toward new and innovative technology.

Many foundations and other nonprofit organizations contribute to the development of technology. In the OECD, about two-thirds of research and development in scientific and technical fields is carried out by industry, and 20 percent and 10 percent respectively by universities and government. But in poorer countries such as Portugal and Mexico the industry contribution is significantly less. The U.S. government spends more than other countries on military research and development, although the proportion has fallen from about 30 percent in the 1980s to less than 20 percent.[2]

[edit] Other economic considerations

Public schools have attempted to introduce varied concepts of technology on the junior high level to better prepare youngsters for subsequent schooling, as well as entrance into the workforce.

[edit] Sociological factors and effects

The use of technology has a great many effects; these may be separated into intended effects and unintended effects. Unintended effects are usually also unanticipated, and often unknown before the arrival of a new technology. Nevertheless, they are often as important as the intended effect.

The most subtle side effects of technology are often sociological. They are subtle because the side effects may go unnoticed unless carefully observed and studied. These may involve gradually occurring changes in the behavior of individuals, groups, institutions, and even entire societies.

[edit] Values

The implementation of technology influences the values of a society by changing expectations and realities. The implementation of technology is also influenced by values. There are (at least) three major, interrelated values that inform, and are informed by, technological innovations:

  • Mechanistic world view: Viewing the universe as a collection of parts, (like a machine), that can be individually analyzed and understood (McGinn). This is a form of reductionism that is rare nowadays. However, the "neo-mechanistic world view" holds that nothing in the universe cannot be understood by the human intellect. Also, while all things are greater than the sum of their parts (e.g., even if we consider nothing more than the information involved in their combination), in principle, even this excess must eventually be understood by human intelligence. That is, no divine or vital principle or essence is involved.
  • Efficiency: A value, originally applied only to machines, but now applied to all aspects of society, so that each element is expected to attain a higher and higher percentage of its maximal possible performance, output, or ability. (McGinn)
  • Social progress: The belief that there is such a thing as social progress, and that, in the main, it is beneficent. Before the Industrial Revolution, and the subsequent explosion of technology, almost all societies believed in a cyclical theory of social movement and, indeed, of all history and the universe. This was, obviously, based on the cyclicity of the seasons, and an agricultural economy's and society's strong ties to that cyclicity. Since much of the world (i.e., everyone but the hyperindustrialized West) is closer to their agricultural roots, they are still much more amenable to cyclicity than progress in history. This may be seen, for example, in Prabhat rainjan sarkar's modern social cycles theory. For a more westernized version of social cyclicity, see Generations : The History of America's Future, 1584 to 2069 (Paperback) by Neil Howe and William Strauss; Harper Perennial; Reprint edition (September 30, 1992); ISBN 0688119123, and subsequent books by these authors.

[edit] Ethics

Winston provides an excellent summary of the ethical implications of technological development and deployment. He states there are four major ethical implications:

  • Challenges traditional ethical norms.
  • Creates an aggregation of effects.
  • Changes the distribution of justice.
  • Provides great power.

But the most important contribution of technology is making life of common people much easier and helping them achieve what was previously not possible.

[edit] Lifestyle

Technology, throughout history, has allowed people to complete more tasks in less time and with less human intellectual or manual labour. Many herald this as a way of making life easier. However, work has continued to be proportional to the amount of energy expended, rather than the quantitiative amount of information or material processed. Technology has had profound effects on lifestyle throughout human history, and as the rate of progress increases, society must deal with both the good and bad implications. In many ways, technology simplifies life.

  • The rise of a leisure class
  • A more informed society can make quicker responses to events and trends
  • Sets the stage for more complex learning tasks
  • Increases multi-tasking
  • Global Networking
  • Creates denser social circles
  • Cheap price

In other ways, technology complicates life.

  • Sweatshops and harsher forms of slavery are more likely to be found in technologically advanced societies, relative to primitive societies.
  • The increasing oppression of technologically advanced societies over those which are not.
  • More people are starving now, in this most technologically advanced age, than at any point in history or pre-history.
  • The increase in transportation technology has brought congestion in some areas.
  • Technicism
  • New forms of danger existing as a consequence of new forms of technology, new types of nuclear reactors, unforeseen genetic mutations as the result of genetic engineering, or perhaps something more subtle which destroys the ozone or warms the planet.
  • New forms of entertainment, such as video games and internet access could have possible social effects on areas such as academic performance.
  • Creates new diseases and disorders such as obesity, laziness and a loss of personality.

[edit] Institutions and groups

Technology often enables organizational and bureaucratic group structures that otherwise and heretofore were simply not possible. Example of this might include:

  • The rise of very large organizations: e.g., governments, the military, health and social welfare institutions, supranational corporations.
  • The commercialization of leisure: sports events, products, etc. (McGinn)
  • The almost instantaneous dispersal of information (especially news) and entertainment around the world.

[edit] International

Technology enables greater knowledge of international issues, values, and cultures. Due mostly to mass transportation and mass media, the world seems to be a much smaller place, due to the following, among others:

  • Globalization of ideas
  • Embeddedness of values
  • Population growth and control
  • Others

[edit] Environment

Most modern technological processes produce unwanted byproducts in addition to the desired products, which is known as industrial waste and pollution. While most material waste is re-used in the industrial process, many forms are released into the environment, with negative environmental side effects, such as pollution and lack of sustainability. Different social and political systems establish different balances between the value they place on additional goods versus the disvalues of waste products and pollution. Some technologies are designed specifically with the environment in mind, but most are designed first for economic or ergonomic effects. Historically, the value of a clean environment and more efficient productive processes has been the result of an increase in the wealth of society, because once people are able to provide for their basic needs, they are able to focus on less-tangible goods such as clean air and water.

The effects of technology on the environment are both obvious and subtle. The more obvious effects include the depletion of nonrenewable natural resources (such as petroleum, coal, ores), and the added pollution of air, water, and land. The more subtle effects include debates over long-term effects (e.g., global warming, deforestation, natural habitat destruction, coastal wetland loss.)

Each wave of technology creates a set of waste previously unknown by humans: toxic waste, radioactive waste, electronic waste.

[edit] Control

[edit] Autonomous technology

In one line of thought, technology develops autonomously, in other words, technology seems to feed on itself, moving forward with a force irresistible by humans. To these individuals, technology is "inherently dynamic and self-augmenting." (McGinn, p. 73)

Jacques Ellul is one proponent of the irresistibleness of technology to humans. He espouses the idea that humanity cannot resist the temptation of expanding our knowledge and our technological abilities. However, he does not believe that this seeming autonomy of technology is inherent. But the perceived autonomy is due to the fact that humans do not adequately consider the responsibility that is inherent in technological processes.

Another proponent of these ideas is Langdon Winner who believes that technological evolution is essentially beyond the control of individuals or society.

[edit] Government

Individuals rely on governmental assistance to control the side effects and negative consequences of technology.

  • Supposed independence of government. An assumption commonly made about the government is that their governance role is neutral or independent. However some argue that governing is a political process, so government will be influenced by political winds of influence. In addition, because government provides much of the funding for technological research and development, it has a vested interest in certain outcomes. Others point out that the world's biggest ecological disasters, such as the Aral Sea, Chernobyl, and Lake Karachay have been caused by government projects, which are not accountable to consumers, so governments should stay out of industry entirely.
  • Liability. One means for controlling technology is to place responsibility for the harm with the agent causing the harm. Government can allow more or less legal liability to fall to the organizations or individuals responsible for damages.
  • Legislation. A source of controversy is the role of industry versus that of government in maintaining a clean environment. While it is generally agreed that industry needs to be held responsible when pollution harms other people, there is disagreement over whether this should be prevented by legislation or civil courts, and whether ecological systems as such should be protected from harm by governments.

[edit] Choice

Society also controls technology through the choices it makes. These choices not only include consumer demands; they also include:

  • the channels of distribution, how do products go from raw materials to consumption to disposal;
  • the cultural beliefs regarding style, freedom of choice, consumerism, materialism, etc.;
  • the economic values we place on the environment, individual wealth, government control, capitalism, etc.

[edit] Technology and philosophy

[edit] Technicism

Generally, technicism is an over reliance or overconfidence in technology as a benefactor of society.

Taken to extreme, some argue that technicism is the belief that humanity will ultimately be able to control the entirety of existence using technology. In other words, human beings will eventually be able to master all problems, supply all wants and needs, possibly even control the future. (For a more complete treatment of the topic, see the work of Egbert Schuurman, for example at [3].) Some, such as Monsma, et al., connect these ideas to the abdication of religion as a higher moral authority.

More commonly, technicism is a criticism of the commonly held belief that newer, more recently-developed technology is "better." For example, more recently-developed computers are faster than older computers, and more recently-developed cars have greater gas efficiency and more features than older cars. Because current technologies are generally accepted as good, future technological developments are not considered circumspectly, resulting in what seems to be a blind acceptance of technological developments.

[edit] Optimism, pessimism and appropriate technology

[edit] Pessimism

On the somewhat pessimistic side are certain philosophers like Herbert Marcuse, Jacques Ellul, and John Zerzan, who believe that technological societies are inherently flawed a priori. They suggest that the result of such a society is to become evermore technological at the cost of freedom and psychological health (and probably physical health in general, as pollution from technological products is dispersed).

Perhaps the most poignant criticisms of technology are found in what are now considered to be dystopian literary classics, for example Aldous Huxley's Brave New World and other writings, Anthony Burgess's A Clockwork Orange, and George Orwell's Nineteen Eighty-Four.

[edit] Optimism

On the other hand, the optimistic assumptions are made by proponents of views or ideologies such as transhumanism and singularitarianism, that view technological development as generally having beneficial effects for the society and the human condition. In these ideologies, technological development is morally good. Some critics see these ideologies as examples of scientism or techno-utopianism and fear the idea of technological singularity which they support. Some technological optimists are Karl Marx and James Hughes.

[edit] Attitude towards technology

The difference in a persons attitude towards technology is dependent on that persons exposure to it rather than the notion that it is age that determines positivity/negativity.

[edit] Appropriate technology

The notion of appropriate technology, however, was developed in the 20th century to describe situations where it was not desirable to use very new technologies or those that required access to some centralized infrastructure or parts or skills imported from elsewhere. The eco-village movement emerged in part due to this concern.

[edit] Theories and concepts in technology

There are many theories and concepts that seek to explain the relationship between technology and society:
