Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way.<ref>Template:Cite book</ref> The word technology can also mean the products resulting from such efforts,<ref>Template:Harvnb: "The first pole, that of the naturalisation of a new discipline within the university curriculum, was presented by Christian Wolff in 1728, in Chapter III of the "Preliminary discourse" to his {{#invoke:Lang|lang}}: 'Technology is the science of skills and works of skill, or, if one prefers, the science of things made by man's labour, chiefly through the use of his hands.'"</ref><ref>Template:Cite book</ref> including both tangible tools such as utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life.
Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the growth of the human brain and the development of language during the Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to communication and ushered in the knowledge economy.
While technology contributes to economic development and improves human prosperity, it can also have negative impacts like pollution and resource depletion, and can cause social harms like technological unemployment resulting from automation. As a result, philosophical and political debates about the role and use of technology, the ethics of technology, and ways to mitigate its downsides are ongoing.
EtymologyEdit
Technology is a term dating back to the early 17th century that meant 'systematic treatment' (from Greek {{#invoke:Lang|lang}}, from the Template:Langx and Template:Wikt-lang (Template:Transliteration), 'study, knowledge').<ref name="Liddell 1980">Template:Cite book</ref><ref>Template:Cite encyclopedia</ref> It is predated in use by the Ancient Greek word Template:Wikt-lang (Template:Transliteration), used to mean 'knowledge of how to make things', which encompassed activities like architecture.<ref>Template:Cite book</ref>
Starting in the 19th century, continental Europeans started using the terms {{#invoke:Lang|lang}} (German) or {{#invoke:Lang|lang}} (French) to refer to a 'way of doing', which included all technical arts, such as dancing, navigation, or printing, whether or not they required tools or instruments.Template:Sfn At the time, {{#invoke:Lang|lang}} (German and French) referred either to the academic discipline studying the "methods of arts and crafts", or to the political discipline "intended to legislate on the functions of the arts and crafts."Template:Sfn The distinction between {{#invoke:Lang|lang}} and {{#invoke:Lang|lang}} is absent in English, and so both were translated as technology. The term was previously uncommon in English and mostly referred to the academic discipline, as in the Massachusetts Institute of Technology.<ref name=jstor40061169>Template:Cite journal</ref>
In the 20th century, as a result of scientific progress and the Second Industrial Revolution, technology stopped being considered a distinct academic discipline and took on the meaning: the systemic use of knowledge to practical ends.<ref>Template:Harvnb: "With the industrial revolution and the important part England played in it, the word technology was to lose this meaning as the subject or thrust of a branch of education, as first in English and then in other languages it embodied all technical activity based on the application of science to practical ends."</ref>
HistoryEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
PrehistoricEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Tools were initially developed by hominids through observation and trial and error.<ref>Template:Cite book</ref> Around 2 Mya (million years ago), they learned to make the first stone tools by hammering flakes off a pebble, forming a sharp hand axe.<ref name=":3">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> This practice was refined 75 kya (thousand years ago) into pressure flaking, enabling much finer work.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The discovery of fire was described by Charles Darwin as "possibly the greatest ever made by man".<ref>Template:Cite book</ref> Archaeological, dietary, and social evidence point to "continuous [human] fire-use" at least 1.5 Mya.<ref>Template:Cite journal</ref> Fire, fueled with wood and charcoal, allowed early humans to cook their food to increase its digestibility, improving its nutrient value and broadening the number of foods that could be eaten.<ref>Template:Cite journal</ref> The cooking hypothesis proposes that the ability to cook promoted an increase in hominid brain size, though some researchers find the evidence inconclusive.<ref>Template:Cite journal</ref> Archaeological evidence of hearths was dated to 790 kya; researchers believe this is likely to have intensified human socialization and may have contributed to the emergence of language.<ref name=worldcat1124046527>Template:Cite book</ref><ref name=20030715nytimes-science>Template:Cite news</ref>
Other technological advances made during the Paleolithic era include clothing and shelter.<ref name=":4">Template:Cite journal</ref> No consensus exists on the approximate time of adoption of either technology, but archaeologists have found archaeological evidence of clothing 90-120 kya<ref>Template:Cite journal</ref> and shelter 450 kya.<ref name=":4" /> As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as 380 kya, humans were constructing temporary wood huts.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite book</ref> Clothing, adapted from the fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa around 200 kya, initially moving to Eurasia.<ref>Template:Cite journal</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite journal</ref>
NeolithicEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
The Neolithic Revolution (or First Agricultural Revolution) brought about an acceleration of technological innovation, and a consequent increase in social complexity.<ref>Template:Cite book</ref> The invention of the polished stone axe was a major advance that allowed large-scale forest clearance and farming.<ref>Template:Cite journal</ref> This use of polished stone axes increased greatly in the Neolithic but was originally used in the preceding Mesolithic in some areas such as Ireland.<ref>Template:Cite book</ref> Agriculture fed larger populations, and the transition to sedentism allowed for the simultaneous raising of more children, as infants no longer needed to be carried around by nomads. Additionally, children could contribute labor to the raising of crops more readily than they could participate in hunter-gatherer activities.<ref name=20060104sciencedaily>Template:Cite news</ref><ref>Template:Cite journal</ref>
With this increase in population and availability of labor came an increase in labor specialization.<ref>Template:Cite book</ref> What triggered the progression from early Neolithic villages to the first cities, such as Uruk, and the first civilizations, such as Sumer, is not specifically known; however, the emergence of increasingly hierarchical social structures and specialized labor, of trade and war among adjacent cultures, and the need for collective action to overcome environmental challenges such as irrigation, are all thought to have played a role.<ref>Template:Cite book</ref>
The invention of writing led to the spread of cultural knowledge and became the basis for history, libraries, schools, and scientific research.<ref>Template:Cite book</ref>
Continuing improvements led to the furnace and bellows and provided, for the first time, the ability to smelt and forge gold, copper, silver, and leadTemplate:Spaced ndashnative metals found in relatively pure form in nature.<ref>Template:Cite journal</ref> 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 10 kya).<ref>Template:Cite EB1911</ref> 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. Eventually, the working of metals led to the discovery of alloys such as bronze and brass (about 4,000 BCE). The first use of iron alloys such as steel dates to around 1,800 BCE.<ref>Template:Cite journal</ref><ref name=hindu001200903261>Template:Cite news</ref>
AncientEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Template:Ancient technology
.jpg){kind=link}
After harnessing fire, humans discovered other forms of energy. The earliest known use of wind power is the sailing ship; the earliest record of a ship under sail is that of a Nile boat dating to around 7,000 BCE.<ref>Template:Cite journal</ref> From prehistoric times, Egyptians likely used the power of the annual flooding of the Nile to irrigate their lands, gradually learning to regulate much of it through purposely built irrigation channels and "catch" basins.<ref>Template:Cite book</ref> The ancient Sumerians in Mesopotamia used a complex system of canals and levees to divert water from the Tigris and Euphrates rivers for irrigation.<ref>Template:Cite book</ref>
Archaeologists estimate that the wheel was invented independently and concurrently in Mesopotamia (in present-day Iraq), the Northern Caucasus (Maykop culture), and Central Europe.<ref>Template:Cite book</ref> Time estimates range from 5,500 to 3,000 BCE with most experts putting it closer to 4,000 BCE.<ref>Template:Cite book</ref> The oldest artifacts with drawings depicting wheeled carts date from about 3,500 BCE.<ref>Template:Cite book</ref> More recently, the oldest-known wooden wheel in the world as of 2024 was found in the Ljubljana Marsh of Slovenia; Austrian experts have established that the wheel is between 5,100 and 5,350 years old.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The invention of the wheel revolutionized trade and war. It did not take long to discover that wheeled wagons could be used to carry heavy loads. The ancient Sumerians used a potter's wheel and may have invented it.<ref name="Kramer1963">Template:Cite book</ref> A stone pottery wheel found in the city-state of Ur dates to around 3,429 BCE,<ref name="Moorey1994">Template:Cite book</ref> and even older fragments of wheel-thrown pottery have been found in the same area.<ref name="Moorey1994" /> 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. The first two-wheeled carts were derived from travois<ref name="Lay1992">Template:Cite book</ref> and were first used in Mesopotamia and Iran in around 3,000 BCE.<ref name="Lay1992" />
The oldest known constructed roadways are the stone-paved streets of the city-state of Ur, dating to Template:Circa,<ref name="Gregersen2012">Template:Cite book</ref> and timber roads leading through the swamps of Glastonbury, England, dating to around the same period.<ref name="Gregersen2012" /> The first long-distance road, which came into use around 3,500 BCE,<ref name="Gregersen2012" /> spanned 2,400 km from the Persian Gulf to the Mediterranean Sea,<ref name="Gregersen2012" /> but was not paved and was only partially maintained.<ref name="Gregersen2012" /> In around 2,000 BCE, the Minoans on the Greek island of Crete built a 50 km road leading from the palace of Gortyn on the south side of the island, through the mountains, to the palace of Knossos on the north side of the island.<ref name="Gregersen2012" /> Unlike the earlier road, the Minoan road was completely paved.<ref name="Gregersen2012" />
Ancient Minoan private homes had running water.<ref name="Eslamian2014">Template:Cite book</ref> A bathtub virtually identical to modern ones was unearthed at the Palace of Knossos.<ref name="Eslamian2014" /><ref name="Lechner2012">Template:Cite book</ref> Several Minoan private homes also had toilets, which could be flushed by pouring water down the drain.<ref name="Eslamian2014" /> The ancient Romans had many public flush toilets,<ref name="Lechner2012" /> which emptied into an extensive sewage system.<ref name="Lechner2012" /> The primary sewer in Rome was the Cloaca Maxima;<ref name="Lechner2012" /> construction began on it in the sixth century BCE and it is still in use today.<ref name="Lechner2012" />
The ancient Romans also had a complex system of aqueducts,<ref name="Aicher1995">Template:Cite book</ref> which were used to transport water across long distances.<ref name="Aicher1995" /> The first Roman aqueduct was built in 312 BCE.<ref name="Aicher1995" /> The eleventh and final ancient Roman aqueduct was built in 226 CE.<ref name="Aicher1995" /> Put together, the Roman aqueducts extended over 450 km,<ref name="Aicher1995" /> but less than 70 km of this was above ground and supported by arches.<ref name="Aicher1995" />
Pre-modernEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Innovations continued through the Middle Ages with the introduction of silk production (in Asia and later Europe), the horse collar, and horseshoes. Simple machines (such as the lever, the screw, and the pulley) were combined into more complicated tools, such as the wheelbarrow, windmills, and clocks.<ref>Template:Cite book</ref> A system of universities developed and spread scientific ideas and practices, including Oxford and Cambridge.<ref>Template:Cite book</ref>
The Renaissance era produced many innovations, including the introduction of the movable type printing press to Europe, which facilitated the communication of knowledge. Technology became increasingly influenced by science, beginning a cycle of mutual advancement.<ref>Template:Cite book</ref>
ModernEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Starting in the United Kingdom in the 18th century, the discovery of steam power set off the Industrial Revolution, which saw wide-ranging technological discoveries, particularly in the areas of agriculture, manufacturing, mining, metallurgy, and transport, and the widespread application of the factory system.<ref>Template:Cite book</ref> This was followed a century later by the Second Industrial Revolution which led to rapid scientific discovery, standardization, and mass production. New technologies were developed, including sewage systems, electricity, light bulbs, electric motors, railroads, automobiles, and airplanes. These technological advances led to significant developments in medicine, chemistry, physics, and engineering.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> They were accompanied by consequential social change, with the introduction of skyscrapers accompanied by rapid urbanization.<ref>Template:Cite book</ref> Communication improved with the invention of the telegraph, the telephone, the radio, and television.<ref>Template:Cite journal</ref>
The 20th century brought a host of innovations. In physics, the discovery of nuclear fission in the Atomic Age led to both nuclear weapons and nuclear power. Analog computers were invented and asserted dominance in processing complex data. While the invention of vacuum tubes allowed for digital computing with computers like the ENIAC, their sheer size precluded widespread use until innovations in quantum physics allowed for the invention of the transistor in 1947, which significantly compacted computers and led the digital transition. Information technology, particularly optical fiber and optical amplifiers, allowed for simple and fast long-distance communication, which ushered in the Information Age and the birth of the Internet. The Space Age began with the launch of Sputnik 1 in 1957, and later the launch of crewed missions to the moon in the 1960s. Organized efforts to search for extraterrestrial intelligence have used radio telescopes to detect signs of technology use, or technosignatures, given off by alien civilizations. In medicine, new technologies were developed for diagnosis (CT, PET, and MRI scanning), treatment (like the dialysis machine, defibrillator, pacemaker, and a wide array of new pharmaceutical drugs), and research (like interferon cloning and DNA microarrays).<ref>Template:Cite book</ref>
Complex manufacturing and construction techniques and organizations are needed to make and maintain more modern technologies, and entire industries have arisen to develop succeeding generations of increasingly more complex tools. Modern technology increasingly relies on training and education – their designers, builders, maintainers, and users often require sophisticated general and specific training.<ref>Template:Cite book</ref> Moreover, these technologies have become so complex that entire fields have developed to support them, including engineering, medicine, and computer science; and other fields have become more complex, such as construction, transportation, and architecture.
ImpactEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Technological change is the largest cause of long-term economic growth.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> Throughout human history, energy production was the main constraint on economic development, and new technologies allowed humans to significantly increase the amount of available energy. First came fire, which made edible a wider variety of foods, and made it less physically demanding to digest them. Fire also enabled smelting, and the use of tin, copper, and iron tools, used for hunting or tradesmanship. Then came the agricultural revolution: humans no longer needed to hunt or gather to survive, and began to settle in towns and cities, forming more complex societies, with militaries and more organized forms of religion.<ref name=":10">Template:Cite journal</ref>
Technologies have contributed to human welfare through increased prosperity, improved comfort and quality of life, and medical progress, but they can also disrupt existing social hierarchies, cause pollution, and harm individuals or groups.
Recent years have brought about a rise in social media's cultural prominence, with potential repercussions on democracy, and economic and social life. Early on, the internet was seen as a "liberation technology" that would democratize knowledge, improve access to education, and promote democracy. Modern research has turned to investigate the internet's downsides, including disinformation, polarization, hate speech, and propaganda.<ref>Template:Cite book</ref>
Since the 1970s, technology's impact on the environment has been criticized, leading to a surge in investment in solar, wind, and other forms of clean energy.
SocialEdit
JobsEdit
Since the invention of the wheel, technologies have helped increase humans' economic output. Past automation has both substituted and complemented labor; machines replaced humans at some lower-paying jobs (for example in agriculture), but this was compensated by the creation of new, higher-paying jobs.<ref>Template:Cite journal</ref> Studies have found that computers did not create significant net technological unemployment.<ref>Template:Cite journal</ref> Due to artificial intelligence being far more capable than computers, and still being in its infancy, it is not known whether it will follow the same trend; the question has been debated at length among economists and policymakers. A 2017 survey found no clear consensus among economists on whether AI would increase long-term unemployment.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> According to the World Economic Forum's "The Future of Jobs Report 2020", AI is predicted to replace 85 million jobs worldwide, and create 97 million new jobs by 2025.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> From 1990 to 2007, a study in the U.S. by MIT economist Daron Acemoglu showed that an addition of one robot for every 1,000 workers decreased the employment-to-population ratio by 0.2%, or about 3.3 workers, and lowered wages by 0.42%.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite journal</ref> Concerns about technology replacing human labor however are long-lasting. As US president Lyndon Johnson said in 1964, "Technology is creating both new opportunities and new obligations for us, opportunity for greater productivity and progress; obligation to be sure that no workingman, no family must pay an unjust price for progress." upon signing the National Commission on Technology, Automation, and Economic Progress bill.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
SecurityEdit
With the growing reliance of technology, there have been security and privacy concerns along with it. Billions of people use different online payment methods, such as WeChat Pay, PayPal, Alipay, and much more to help transfer money. Although security measures are placed, some criminals are able to bypass them.<ref name=":11">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In March 2022, North Korea used Blender.io, a mixer which helped them to hide their cryptocurrency exchanges, to launder over $20.5 million in cryptocurrency, from Axie Infinity, and steal over $600 million worth of cryptocurrency from the game's owner. Because of this, the U.S. Treasury Department sanctioned Blender.io, which marked the first time it has taken action against a mixer, to try to crack down on North Korean hackers.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The privacy of cryptocurrency has been debated. Although many customers like the privacy of cryptocurrency, many also argue that it needs more transparency and stability.<ref name=":11" />
EnvironmentalEdit
Technology can have both positive and negative effects on the environment. Environmental technology, describes an array of technologies which seek to reverse, mitigate or halt environmental damage to the environment. This can include measures to halt pollution through environmental regulations, capture and storage of pollution, or using pollutant byproducts in other industries.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Other examples of environmental technology include deforestation and the reversing of deforestation.<ref>Template:Cite journal</ref> Emerging technologies in the fields of climate engineering may be able to halt or reverse global warming and its environmental impacts,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> although this remains highly controversial.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> As technology has advanced, so too has the negative environmental impact, with increased release of greenhouse gases, including methane, nitrous oxide and carbon dioxide, into the atmosphere, causing the greenhouse effect. This continues to gradually heat the earth, causing global warming and climate change. Measures of technological innovation correlates with a rise in greenhouse gas emissions.<ref>Template:Cite journal</ref>
PollutionEdit
Pollution, the presence of contaminants in an environment that causes adverse effects, could have been present as early as the Inca Empire. They used a lead sulfide flux in the smelting of ores, along with the use of a wind-drafted clay kiln, which released lead into the atmosphere and the sediment of rivers.<ref>Template:Cite book</ref>
PhilosophyEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Philosophy of technology is a branch of philosophy that studies the "practice of designing and creating artifacts", and the "nature of the things so created."<ref name=":5">Template:Cite encyclopedia</ref> It emerged as a discipline over the past two centuries, and has grown "considerably" since the 1970s.<ref name=":8">Template:Cite book</ref> The humanities philosophy of technology is concerned with the "meaning of technology for, and its impact on, society and culture".<ref name=":5" />
Initially, technology was seen as an extension of the human organism that replicated or amplified bodily and mental faculties.<ref>Template:Cite journal</ref> Marx framed it as a tool used by capitalists to oppress the proletariat, but believed that technology would be a fundamentally liberating force once it was "freed from societal deformations". Second-wave philosophers like Ortega later shifted their focus from economics and politics to "daily life and living in a techno-material culture", arguing that technology could oppress "even the members of the bourgeoisie who were its ostensible masters and possessors." Third-stage philosophers like Don Ihde and Albert Borgmann represent a turn toward de-generalization and empiricism, and considered how humans can learn to live with technology.<ref name=":8" />Template:Page needed
Early scholarship on technology was split between two arguments: technological determinism, and social construction. Technological determinism is the idea that technologies cause unavoidable social changes.<ref name=":9">Template:Cite book</ref>Template:Rp It usually encompasses a related argument, technological autonomy, which asserts that technological progress follows a natural progression and cannot be prevented.<ref>Template:Cite book</ref> Social constructivistsTemplate:Who argue that technologies follow no natural progression, and are shaped by cultural values, laws, politics, and economic incentives. Modern scholarship has shifted towards an analysis of sociotechnical systems, "assemblages of things, people, practices, and meanings", looking at the value judgments that shape technology.<ref name=":9" />Template:Page needed
Cultural critic Neil Postman distinguished tool-using societies from technological societies and from what he called "technopolies", societies that are dominated by an ideology of technological and scientific progress to the detriment of other cultural practices, values, and world views.<ref>Template:Cite book</ref> Herbert Marcuse and John Zerzan suggest that technological society will inevitably deprive us of our freedom and psychological health.<ref>Template:Cite book</ref>
EthicsEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} The ethics of technology is an interdisciplinary subfield of ethics that analyzes technology's ethical implications and explores ways to mitigate potential negative impacts of new technologies. There is a broad range of ethical issues revolving around technology, from specific areas of focus affecting professionals working with technology to broader social, ethical, and legal issues concerning the role of technology in society and everyday life.<ref>Template:Cite book</ref>
Prominent debates have surrounded genetically modified organisms, the use of robotic soldiers, algorithmic bias, and the issue of aligning AI behavior with human values.<ref name="Al-Rodhan">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Technology ethics encompasses several key fields: Bioethics looks at ethical issues surrounding biotechnologies and modern medicine, including cloning, human genetic engineering, and stem cell research. Computer ethics focuses on issues related to computing. Cyberethics explores internet-related issues like intellectual property rights, privacy, and censorship. Nanoethics examines issues surrounding the alteration of matter at the atomic and molecular level in various disciplines including computer science, engineering, and biology. And engineering ethics deals with the professional standards of engineers, including software engineers and their moral responsibilities to the public.<ref name="Luppicini, R. 20082">Template:Cite book</ref>
A wide branch of technology ethics is concerned with the ethics of artificial intelligence: it includes robot ethics, which deals with ethical issues involved in the design, construction, use, and treatment of robots,<ref name="Veruggio2002">Template:Cite journal</ref> as well as machine ethics, which is concerned with ensuring the ethical behavior of artificially intelligent agents.<ref name="Anderson2011">Template:Cite book</ref> Within the field of AI ethics, significant yet-unsolved research problems include AI alignment (ensuring that AI behaviors are aligned with their creators' intended goals and interests) and the reduction of algorithmic bias. Some researchers have warned against the hypothetical risk of an AI takeover, and have advocated for the use of AI capability control in addition to AI alignment methods.
Other fields of ethics have had to contend with technology-related issues, including military ethics, media ethics, and educational ethics.
Futures studiesEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Futures studies is the study of social and technological progress. It aims to explore the range of plausible futures and incorporate human values in the development of new technologies.<ref name=":1" />Template:Rp More generally, futures researchers are interested in improving "the freedom and welfare of humankind".<ref name=":1" />Template:Rp It relies on a thorough quantitative and qualitative analysis of past and present technological trends, and attempts to rigorously extrapolate them into the future.<ref name=":1">Template:Cite book</ref> Science fiction is often used as a source of ideas.<ref name=":1" />Template:Rp Futures research methodologies include survey research, modeling, statistical analysis, and computer simulations.<ref name=":1" />Template:Rp
Existential riskEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Existential risk researchers analyze risks that could lead to human extinction or civilizational collapse, and look for ways to build resilience against them.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=":0">Template:Cite journal</ref> Relevant research centers include the Cambridge Center for the Study of Existential Risk, and the Stanford Existential Risk Initiative.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Future technologies may contribute to the risks of artificial general intelligence, biological warfare, nuclear warfare, nanotechnology, anthropogenic climate change, global warming, or stable global totalitarianism, though technologies may also help us mitigate asteroid impacts and gamma-ray bursts.<ref>Template:Cite book</ref> In 2019 philosopher Nick Bostrom introduced the notion of a vulnerable world, "one in which there is some level of technological development at which civilization almost certainly gets devastated by default", citing the risks of a pandemic caused by bioterrorists, or an arms race triggered by the development of novel armaments and the loss of mutual assured destruction.<ref name="Bostrom 2019">Template:Cite journal</ref> He invites policymakers to question the assumptions that technological progress is always beneficial, that scientific openness is always preferable, or that they can afford to wait until a dangerous technology has been invented before they prepare mitigations.<ref name="Bostrom 2019" />
Emerging technologiesEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Emerging technologies are novel technologies whose development or practical applications are still largely unrealized. They include nanotechnology, biotechnology, robotics, 3D printing, and blockchains.
In 2005, futurist Ray Kurzweil claimed the next technological revolution would rest upon advances in genetics, nanotechnology, and robotics, with robotics being the most impactful of the three technologies.<ref>Template:Cite book</ref> Genetic engineering will allow far greater control over human biological nature through a process called directed evolution. Some thinkers believe that this may shatter our sense of self, and have urged for renewed public debate exploring the issue more thoroughly;<ref>Template:Cite journal</ref> others fear that directed evolution could lead to eugenics or extreme social inequality. Nanotechnology will grant us the ability to manipulate matter "at the molecular and atomic scale",<ref>Template:Cite news</ref> which could allow us to reshape ourselves and our environment in fundamental ways.<ref>Template:Cite book</ref> Nanobots could be used within the human body to destroy cancer cells or form new body parts, blurring the line between biology and technology.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Autonomous robots have undergone rapid progress, and are expected to replace humans at many dangerous tasks, including search and rescue, bomb disposal, firefighting, and war.<ref>Template:Cite book</ref>
Estimates on the advent of artificial general intelligence vary, but half of machine learning experts surveyed in 2018 believe that AI will "accomplish every task better and more cheaply" than humans by 2063, and automate all human jobs by 2140.<ref>Template:Cite journal</ref> This expected technological unemployment has led to calls for increased emphasis on computer science education and debates about universal basic income. Political science experts predict that this could lead to a rise in extremism, while others see it as an opportunity to usher in a post-scarcity economy.
MovementsEdit
Appropriate technologyEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Some segments of the 1960s hippie counterculture grew to dislike urban living and developed a preference for locally autonomous, sustainable, and decentralized technology, termed appropriate technology. This later influenced hacker culture and technopaganism.
Technological utopianismEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Technological utopianism refers to the belief that technological development is a moral good, which can and should bring about a utopia, that is, a society in which laws, governments, and social conditions serve the needs of all its citizens.<ref>Template:Cite book</ref> Examples of techno-utopian goals include post-scarcity economics, life extension, mind uploading, cryonics, and the creation of artificial superintelligence. Major techno-utopian movements include transhumanism and singularitarianism.
The transhumanism movement is founded upon the "continued evolution of human life beyond its current human form" through science and technology, informed by "life-promoting principles and values."<ref>Template:Cite book</ref> The movement gained wider popularity in the early 21st century.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Singularitarians believe that machine superintelligence will "accelerate technological progress" by orders of magnitude and "create even more intelligent entities ever faster", which may lead to a pace of societal and technological change that is "incomprehensible" to us. This event horizon is known as the technological singularity.<ref>Template:Cite book</ref>
Major figures of techno-utopianism include Ray Kurzweil and Nick Bostrom. Techno-utopianism has attracted both praise and criticism from progressive, religious, and conservative thinkers.<ref>Template:Cite book</ref>
Anti-technology backlashEdit
Template:See also Technology's central role in our lives has drawn concerns and backlash. The backlash against technology is not a uniform movement and encompasses many heterogeneous ideologies.<ref>Template:Cite book</ref>
The earliest known revolt against technology was Luddism, a pushback against early automation in textile production. Automation had resulted in a need for fewer workers, a process known as technological unemployment.
Between the 1970s and 1990s, American terrorist Ted Kaczynski carried out a series of bombings across America and published the Unabomber Manifesto denouncing technology's negative impacts on nature and human freedom. The essay resonated with a large part of the American public.<ref>Template:Cite journal</ref> It was partly inspired by Jacques Ellul's The Technological Society.<ref>Template:Cite journal</ref>
Some subcultures, like the off-the-grid movement, advocate a withdrawal from technology and a return to nature. The ecovillage movement seeks to reestablish harmony between technology and nature.<ref>Template:Cite journal</ref>
Relation to science and engineeringEdit
Template:See also Engineering is the process by which technology is developed. It often requires problem-solving under strict constraints.<ref name=":7" /> Technological development is "action-oriented", while scientific knowledge is fundamentally explanatory.<ref>Template:Cite journal</ref> Polish philosopher Henryk Skolimowski framed it like so: "science concerns itself with what Template:Em, technology with what Template:Em."<ref>Template:Cite journal</ref>Template:Rp
The direction of causality between scientific discovery and technological innovation has been debated by scientists, philosophers and policymakers.<ref>Template:Cite journal</ref> Because innovation is often undertaken at the edge of scientific knowledge, most technologies are not derived from scientific knowledge, but instead from engineering, tinkering and chance.<ref name=":6">Template:Cite book</ref>Template:Rp For example, in the 1940s and 1950s, when knowledge of turbulent combustion or fluid dynamics was still crude, jet engines were invented through "running the device to destruction, analyzing what broke [...] and repeating the process".<ref name=":7">Template:Cite journal</ref> Scientific explanations often follow technological developments rather than preceding them.<ref name=":6" />Template:Rp Many discoveries also arose from pure chance, like the discovery of penicillin as a result of accidental lab contamination.<ref>Template:Cite book</ref> Since the 1960s, the assumption that government funding of basic research would lead to the discovery of marketable technologies has lost credibility.<ref>Template:Cite journal</ref><ref>Template:Cite book</ref> Probabilist Nassim Taleb argues that national research programs that implement the notions of serendipity and convexity through frequent trial and error are more likely to lead to useful innovations than research that aims to reach specific outcomes.<ref name=":6" /><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Despite this, modern technology is increasingly reliant on deep, domain-specific scientific knowledge. In 1975, there was an average of one citation of scientific literature in every three patents granted in the U.S.; by 1989, this increased to an average of one citation per patent. The average was skewed upwards by patents related to the pharmaceutical industry, chemistry, and electronics.<ref>Template:Cite journal</ref> A 2021 analysis shows that patents that are based on scientific discoveries are on average 26% more valuable than equivalent non-science-based patents.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Other animal speciesEdit
The use of basic technology is also a feature of non-human animal species. Tool use was once considered a defining characteristic of the genus Homo.<ref>Template:Cite journal</ref> This view was supplanted after discovering evidence of tool use among chimpanzees and other primates,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> dolphins,<ref name="20050607bbc">Template:Cite news</ref> and crows.<ref name=nbcnews21135366>Template:Cite news</ref><ref>Template:Cite journal</ref> For example, researchers have observed wild chimpanzees using basic foraging tools, pestles, levers, using leaves as sponges, and tree bark or vines as probes to fish termites.<ref>Template:Cite book</ref> West African chimpanzees use stone hammers and anvils for cracking nuts,<ref>Template:Cite journal</ref> as do capuchin monkeys of Boa Vista, Brazil.<ref name=20090115newscientist>Template:Cite news</ref> Tool use is not the only form of animal technology use; for example, beaver dams, built with wooden sticks or large stones, are a technology with "dramatic" impacts on river habitats and ecosystems.<ref>Template:Cite conference</ref>
In popular cultureEdit
Template:See also The relationship of humanity with technology has been explored in science-fiction literature, for example in Brave New World, A Clockwork Orange, Nineteen Eighty-Four, Isaac Asimov's essays, and movies like Minority Report, Total Recall, Gattaca, and Inception. It has spawned the dystopian and futuristic cyberpunk genre, which juxtaposes futuristic technology with societal collapse, dystopia or decay.<ref>Template:Cite book</ref> Notable cyberpunk works include William Gibson's Neuromancer novel, and movies like Blade Runner, and The Matrix.

"Is life likely to exist elsewhere in the [Milky Way] galaxy? Almost certainly yes, given the speed with which it appeared on Earth. Is another technological civilization likely to exist today? Almost certainly no, given the chain of circumstances that led to our existence. These considerations suggest that we are unique not just on our planet but in the whole Milky Way. And if our planet is so special, it becomes all the more important to preserve this unique world for ourselves, our descendants and the many creatures that call Earth home." (p. 99.)
