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. The privacy of cryptocurrency has been debated. Although many customers like

273-537: A pitch accent . In Modern Greek, all vowels and consonants are short. Many vowels and diphthongs once pronounced distinctly are pronounced as /i/ ( iotacism ). Some of the stops and glides in diphthongs have become fricatives , and the pitch accent has changed to a stress accent . Many of the changes took place in the Koine Greek period. The writing system of Modern Greek, however, does not reflect all pronunciation changes. The examples below represent Attic Greek in

364-472: A lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean Greek , but its relationship to the historical dialects and

455-419: A lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either a fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence. Regarding the speech of the ancient Macedonians diverse theories have been put forward, but the epigraphic activity and the archaeological discoveries in

546-543: A prefix /e-/, called the augment . This was probably originally a separate word, meaning something like "then", added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect, and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist). The two kinds of augment in Greek are syllabic and quantitative. The syllabic augment

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 utopianism refers to

728-411: 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. Since

819-517: A role. The invention of writing led to the spread of cultural knowledge and became the basis for history, libraries , schools, and scientific research. Continuing improvements led to the furnace and bellows and provided, for the first time, the ability to smelt and forge gold, copper, silver, and lead – native metals found in relatively pure form in nature. The advantages of copper tools over stone, bone and wooden tools were quickly apparent to early humans, and native copper

910-671: A separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek , and Koine may be classified as Ancient Greek in a wider sense. There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek was a pluricentric language , divided into many dialects. The main dialect groups are Attic and Ionic , Aeolic , Arcadocypriot , and Doric , many of them with several subdivisions. Some dialects are found in standardized literary forms in literature , while others are attested only in inscriptions. There are also several historical forms. Homeric Greek

1092-609: A standard subject of study in educational institutions of the Western world since the Renaissance . This article primarily contains information about the Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period ( c.  300 BC ), Ancient Greek was followed by Koine Greek , which is regarded as

1183-510: A vowel or /n s r/ ; final stops were lost, as in γάλα "milk", compared with γάλακτος "of milk" (genitive). Ancient Greek of the classical period also differed in both the inventory and distribution of original PIE phonemes due to numerous sound changes, notably the following: The pronunciation of Ancient Greek was very different from that of Modern Greek . Ancient Greek had long and short vowels ; many diphthongs ; double and single consonants; voiced, voiceless, and aspirated stops ; and

1274-556: Is a literary form of Archaic Greek (derived primarily from Ionic and Aeolic) used in the epic poems , the Iliad and the Odyssey , and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic and other Classical-era dialects. The origins, early form and development of the Hellenic language family are not well understood because of

1365-418: Is added to stems beginning with consonants, and simply prefixes e (stems beginning with r , however, add er ). The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel: Some verbs augment irregularly; the most common variation is e → ei . The irregularity can be explained diachronically by the loss of s between vowels, or that of the letter w , which affected

Emerging technologies are novel technologies whose development or practical applications are still largely unrealized. They include nanotechnology , biotechnology , robotics , 3D printing , blockchains , and artificial intelligence . In 2005, futurist Ray Kurzweil claimed

1547-499: Is an interdisciplinary subfield of ethics that analyzes technology's ethical implications and explores ways to mitigate the 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. Prominent debates have surrounded genetically modified organisms ,

1638-644: Is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, as exemplified in the poems of the Boeotian poet Pindar who wrote in Doric with a small Aeolic admixture. Thessalian likewise had come under Northwest Greek influence, though to

1729-448: Is considered by some linguists to have been closely related to Greek . Among Indo-European branches with living descendants, Greek is often argued to have the closest genetic ties with Armenian (see also Graeco-Armenian ) and Indo-Iranian languages (see Graeco-Aryan ). Ancient Greek differs from Proto-Indo-European (PIE) and other Indo-European languages in certain ways. In phonotactics , ancient Greek words could end only in

The word technology can also mean the products resulting from such efforts, 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

2275-481: Is the largest cause of long-term economic growth. 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

Based on the conclusions drawn by several studies and findings such as Pella curse tablet , Emilio Crespo and other scholars suggest that ancient Macedonian was a Northwest Doric dialect , which shares isoglosses with its neighboring Thessalian dialects spoken in northeastern Thessaly . Some have also suggested an Aeolic Greek classification. The Lesbian dialect

Archaeologists estimate that the wheel was invented independently and concurrently in Mesopotamia (in present-day Iraq ), the Northern Caucasus ( Maykop culture ), and Central Europe. Time estimates range from 5,500 to 3,000 BCE with most experts putting it closer to 4,000 BCE. The oldest artifacts with drawings depicting wheeled carts date from about 3,500 BCE. More recently,

2821-602: 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. 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%. Concerns about technology replacing human labor however are long-lasting. As US president Lyndon Johnson said in 1964, "Technology

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. 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.

3185-501: The present , future , and imperfect are imperfective in aspect; the aorist , present perfect , pluperfect and future perfect are perfective in aspect. Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. The infinitives and participles correspond to the finite combinations of tense, aspect, and voice. The indicative of past tenses adds (conceptually, at least)

3276-445: 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

Initially, technology was seen as an extension of the human organism that replicated or amplified bodily and mental faculties. 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

3640-1031: The 5th century BC. Ancient pronunciation cannot be reconstructed with certainty, but Greek from the period is well documented, and there is little disagreement among linguists as to the general nature of the sounds that the letters represent. /oː/ raised to [uː] , probably by the 4th century BC. Greek, like all of the older Indo-European languages , is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In ancient Greek, nouns (including proper nouns) have five cases ( nominative , genitive , dative , accusative , and vocative ), three genders ( masculine , feminine , and neuter ), and three numbers (singular, dual , and plural ). Verbs have four moods ( indicative , imperative , subjunctive , and optative ) and three voices (active, middle, and passive ), as well as three persons (first, second, and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"):

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. With this increase in population and availability of labor came an increase in labor specialization . What triggered

The ancient Romans had many public flush toilets, which emptied into an extensive sewage system . The primary sewer in Rome was the Cloaca Maxima ; construction began on it in the sixth century BCE and it is still in use today. The ancient Romans also had a complex system of aqueducts , which were used to transport water across long distances. The first Roman aqueduct

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. Tools were initially developed by hominids through observation and trial and error . Around 2 Mya (million years ago), they learned to make

4459-493: 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. 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

4641-550: The aorist. Following Homer 's practice, the augment is sometimes not made in poetry , especially epic poetry. The augment sometimes substitutes for reduplication; see below. Almost all forms of the perfect, pluperfect, and future perfect reduplicate the initial syllable of the verb stem. (A few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) The three types of reduplication are: Irregular duplication can be understood diachronically. For example, lambanō (root lab ) has

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 and were first used in Mesopotamia and Iran in around 3,000 BCE. The oldest known constructed roadways are

5187-519: The communication of knowledge. Technology became increasingly influenced by science, beginning a cycle of mutual advancement.

Nanotechnology will grant us the ability to manipulate matter "at the molecular and atomic scale", which could allow us to reshape ourselves and our environment in fundamental ways. Nanobots could be used within the human body to destroy cancer cells or form new body parts, blurring

6188-690: The line between biology and technology. 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. 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. 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

6279-417: The next technological revolution would rest upon advances in genetics , nanotechnology , and robotics , with robotics being the most impactful of the three technologies. 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

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. Other examples of environmental technology include deforestation and

6916-417: 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

7007-409: The range of plausible futures and to incorporate human values in the development of new technologies. More generally, futures researchers are interested in improving "the freedom and welfare of humankind". It relies on a thorough quantitative and qualitative analysis of past and present technological trends, and attempts to rigorously extrapolate them into the future. Science fiction is often used as

7098-401: The reversing of deforestation. Emerging technologies in the fields of climate engineering may be able to halt or reverse global warming and its environmental impacts, although this remains highly controversial. 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

7189-403: The role and use of technology, the ethics of technology , and ways to mitigate its downsides are ongoing. Technology is a term dating back to the early 17th century that meant 'systematic treatment' (from Greek Τεχνολογία , from the Greek : τέχνη , romanized :  tékhnē , lit.   'craft, art' and -λογία , 'study, knowledge'). It is predated in use by

7280-523: The stone-paved streets of the city-state of Ur, dating to c.  4,000 BCE , and timber roads leading through the swamps of Glastonbury , England, dating to around the same period. The first long-distance road, which came into use around 3,500 BCE, spanned 2,400 km from the Persian Gulf to the Mediterranean Sea , but was not paved and was only partially maintained. In around 2,000 BCE,

7371-517: The syllabic script Linear B . Beginning in the 8th century BC, however, the Greek alphabet became standard, albeit with some variation among dialects. Early texts are written in boustrophedon style, but left-to-right became standard during the classic period. Modern editions of ancient Greek texts are usually written with accents and breathing marks , interword spacing , modern punctuation , and sometimes mixed case , but these were all introduced later. The beginning of Homer 's Iliad exemplifies

7462-471: The time, Technologie (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." The distinction between Technik and Technologie is absent in English, and so both were translated as technology . The term was previously uncommon in English and mostly referred to

7553-527: The use of robotic soldiers, algorithmic bias , and the issue of aligning AI behavior with human values. 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

7644-506: The value judgments that shape technology. 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. Herbert Marcuse and John Zerzan suggest that technological society will inevitably deprive us of our freedom and psychological health. The ethics of technology

7735-527: The widespread application of the factory system . 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. They were accompanied by consequential social change, with

7826-529: 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. Early scholarship on technology

7917-475: Was Aeolic. For example, fragments of the works of the poet Sappho from the island of Lesbos are in Aeolian. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, or to an island. Doric notably had several intermediate divisions as well, into Island Doric (including Cretan Doric ), Southern Peloponnesus Doric (including Laconian ,

8008-560: Was built in 312 BCE. The eleventh and final ancient Roman aqueduct was built in 226 CE. Put together, the Roman aqueducts extended over 450 km, but less than 70 km of this was above ground and supported by arches. 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

8099-513: Was compensated by the creation of new, higher-paying jobs. Studies have found that computers did not create significant net technological unemployment . 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. According to

8190-536: Was probably used from near the beginning of Neolithic times (about 10 kya). 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. After harnessing fire, humans discovered other forms of energy. The earliest known use of wind power

8281-649: Was split between two arguments: technological determinism , and social construction . Technological determinism is the idea that technologies cause unavoidable social changes. It usually encompasses a related argument, technological autonomy, which asserts that technological progress follows a natural progression and cannot be prevented. Social constructivists 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
