How Technology Affects Our Lives – Essay

Do you wish to explore the use of information technology in daily life? Essays like the one below discuss this topic in depth. Read on to find out more.


Technology in communication, technology in healthcare, technology in government, technology in education, technology in business, negative impact of technology.

Technology is a vital component of life in the modern world. People are so dependent on technology that they cannot live without it. Technology is important and useful in all areas of human life today. It has made life easy and comfortable by making communication and transport faster and easier (Harrington, 2011, p.35).

It has made education accessible to all and has improved healthcare services. Technology has made the world smaller and a better place to live. Without technology, fulfilling human needs would be a difficult task. Before the advent of technology, human beings were still fulfilling their needs. However, with technology, fulfillment of needs has become easier and faster.

It is unimaginable how life would be without technology. Technology is useful in the following areas: transport, communication, interaction, education, healthcare, and business (Harrington, 2011, p.35). Despite its benefits, technology has negative impacts on society. Examples of negative impacts of technology include the development of controversial medical practices such as stem cell research and the embracement of solitude due to changes in interaction methods. For example, social media has changed the way people interact.

Technology has led to the introduction of cloning, which is highly controversial because of its ethical and moral implications. The growth of technology has changed the world significantly and has influenced life in a great way. Technology is changing every day and continuing to influence areas of communication, healthcare, governance, education, and business.

Technology has contributed fundamentally in improving people’s lifestyles. It has improved communication by incorporating the Internet and devices such as mobile phones into people’s lives. The first technological invention to have an impact on communication was the discovery of the telephone by Graham Bell in 1875.

Since then, other inventions such as the Internet and the mobile phone have made communication faster and easier. For example, the Internet has improved ways through which people exchange views, opinions, and ideas through online discussions (Harrington, 2011, p.38). Unlike in the past when people who were in different geographical regions could not easily communicate, technology has eradicated that communication barrier. People in different geographical regions can send and receive messages within seconds.

Online discussions have made it easy for people to keep in touch. In addition, they have made socializing easy. Through online discussions, people find better solutions to problems by exchanging opinions and ideas (Harrington, 2011, p.39). Examples of technological inventions that facilitate online discussions include emails, online forums, dating websites, and social media sites.

Another technological invention that changed communication was the mobile phone. In the past, people relied on letters to send messages to people who were far away. Mobile phones have made communication efficient and reliable. They facilitate both local and international communication.

In addition, they enable people to respond to emergencies and other situations that require quick responses. Other uses of cell phones include the transfer of data through applications such as infrared and Bluetooth, entertainment, and their use as miniature personal computers (Harrington, 2011, p.40).

The latest versions of mobile phones are fitted with applications that enable them to access the Internet. This provides loads of information in diverse fields for mobile phone users. For business owners, mobile phones enhance the efficiency of their business operations because they are able to keep in touch with their employees and suppliers (Harrington, 2011, p.41). In addition, they are able to receive any information about the progress of their business in a short period of time.

Technology has contributed significantly to the healthcare sector. For example, it has made vital contributions in the fields of disease prevention and health promotion. Technology has aided in the understanding of the pathophysiology of diseases, which has led to the prevention of many diseases. For example, understanding the pathophysiology of the gastrointestinal tract and blood diseases has aided in their effective management (Harrington, 2011, p.49).

Technology has enabled practitioners in the medical field to make discoveries that have changed the healthcare sector. These include the discovery that peptic ulceration is caused by a bacterial infection and the development of drugs to treat schizophrenia and depressive disorders that afflict a greater portion of the population (Harrington, 2011, p.53). The development of vaccines against polio and measles led to their total eradication.

Children who are vaccinated against these diseases are not at risk of contracting the diseases. The development of vaccines was facilitated by technology, without which certain diseases would still be causing deaths in great numbers. Vaccines play a significant role in disease prevention.

Technology is used in health promotion in different ways. First, health practitioners use various technological methods to improve health care. eHealth refers to the use of information technology to improve healthcare by providing information on the Internet to people. In this field, technology is used in three main ways.

These include its use as an intervention tool, its use in conducting research studies, and its use for professional development (Lintonen et al, 2008, p. 560). According to Lintonenet al (2008), “e-health is the use of emerging information and communications technology, especially the internet, to improve or enable health and healthcare.” (p.560). It is largely used to support health care interventions that are mainly directed towards individual persons. Secondly, it is used to improve the well-being of patients during recovery.

Bedside technology has contributed significantly in helping patients recover. For example, medical professionals have started using the Xbox computer technology to develop a revolutionary process that measures limb movements in stroke patients (Tanja-Dijkstra, 2011, p.48). This helps them recover their manual competencies. The main aim of this technology is to help stroke patients do more exercises to increase their recovery rate and reduce the frequency of visits to the hospital (Lintonen et al, 2008, p. 560).

The government has utilized technology in two main areas. These include the facilitation of the delivery of citizen services and the improvement of defense and national security (Scholl, 2010, p.62). The government is spending large sums of money on wireless technologies, mobile gadgets, and technological applications. This is in an effort to improve their operations and ensure that the needs of citizens are fulfilled.

For example, in order to enhance safety and improve service delivery, Cisco developed a networking approach known as Connected Communities. This networking system connects citizens with the government and the community. The system was developed to improve the safety and security of citizens, improve service delivery by the government, empower citizens, and encourage economic development.

The government uses technology to provide information and services to citizens. This encourages economic development and fosters social inclusion (Scholl, 2010, p.62). Technology is also useful in improving national security and the safety of citizens. It integrates several wireless technologies and applications that make it easy for security agencies to access and share important information effectively. Technology is widely used by security agencies to reduce vulnerability to terrorism.

Technologically advanced gadgets are used in airports, hospitals, shopping malls, and public buildings to screen people for explosives and potentially dangerous materials or gadgets that may compromise the safety of citizens (Bonvillian and Sharp, 2001, par2). In addition, security agencies use surveillance systems to restrict access to certain areas. They also use technologically advanced screening and tracking methods to improve security in places that are prone to terrorist attacks (Bonvillian and Sharp, 2001, par3).

Technology has made significant contributions in the education sector. It is used to enhance teaching and learning through the use of different technological methods and resources. These include classrooms with digital tools such as computers that facilitate learning, online learning schools, blended learning, and a wide variety of online learning resources (Barnett, 1997, p.74). Digital learning tools that are used in classrooms facilitate learning in different ways. They expand the scope of learning materials and experiences for students, improve student participation in learning, make learning easier and quick, and reduce the cost of education (Barnett, 1997, p.75). For example, online schools and free learning materials reduce the costs that are incurred in purchasing learning materials. They are readily available online. In addition, they reduce the expenses that are incurred in program delivery.

Technology has improved the process of teaching by introducing new methods that facilitate connected teaching. These methods virtually connect teachers to their students. Teachers are able to provide learning materials and the course content to students effectively. In addition, teachers are able to give students an opportunity to personalize learning and access all learning materials that they provide. Technology enables teachers to serve the academic needs of different students.

In addition, it enhances learning because the problem of distance is eradicated, and students can contact their teachers easily (Barnett, 1997, p.76). Technology plays a significant role in changing how teachers teach. It enables educators to evaluate the learning abilities of different students in order to devise teaching methods that are most efficient in the achievement of learning objectives.

Through technology, teachers are able to relate well with their students, and they are able to help and guide them. Educators assume the role of coaches, advisors, and experts in their areas of teaching. Technology helps make teaching and learning enjoyable and gives it meaning that goes beyond the traditional classroom set-up system (Barnett, 1997, p.81).

Technology is used in the business world to improve efficiency and increase productivity. Most important, technology is used as a tool to foster innovation and creativity (Ray, 2004, p.62). Other benefits of technology to businesses include the reduction of injury risk to employees and improved competitiveness in the markets. For example, many manufacturing businesses use automated systems instead of manual systems. These systems eliminate the costs of hiring employees to oversee manufacturing processes.

They also increase productivity and improve the accuracy of the processes because of the reduction of errors (Ray, 2004, p.63). Technology improves productivity due to Computer-aided Manufacturing (CAM), Computer-integrated Manufacturing (CIM), and Computer-aided Design (CAD). CAM reduces labor costs, increases the speed of production, and ensures a higher level of accuracy (Hunt, 2008, p.44). CIM reduces labor costs, while CAD improves the quality and standards of products and reduces the cost of production.

Another example of the use of technology in improving productivity and output is the use of database systems to store data and information. Many businesses store their data and other information in database systems that make accessibility of information fast, easy, and reliable (Pages, 2010, p.44).

Technology has changed how international business is conducted. With the advent of e-commerce, businesses became able to trade through the Internet on the international market (Ray, 2004, p.69). This means that there is a large market for products and services. In addition, it implies that most markets are open 24 hours a day.

For example, customers can shop for books or music on at any time of the day. E-commerce has given businesses the opportunity to expand and operate internationally. Countries such as China and Brazil are taking advantage of opportunities presented by technology to grow their economy.

E-commerce reduces the complexities involved in conducting international trade (Ray, 2004, p.71). Its many components make international trade easy and fast. For example, a BOES system allows merchants to execute trade transactions in any language or currency, monitor all steps involved in transactions, and calculate all costs involved, such as taxes and freight costs (Yates, 2006, p.426).

Financial researchers claim that a BOES system is capable of reducing the cost of an international transaction by approximately 30% (Ray, 2004, p.74). BOES enables businesses to import and export different products through the Internet. This system of trade is efficient and creates a fair environment in which small and medium-sized companies can compete with large companies that dominate the market.

Despite its many benefits, technology has negative impacts. It has negative impacts on society because it affects communication and has changed the way people view social life. First, people have become more anti-social because of changes in methods of socializing (Harrington, 2008, p.103). Today, one does not need to interact physically with another person in order to establish a relationship.

The Internet is awash with dating sites that are full of people looking for partners and friends. The ease of forming friendships and relationships through the Internet has discouraged many people from engaging in traditional socializing activities. Secondly, technology has affected the economic statuses of many families because of high rates of unemployment. People lose jobs when organizations and businesses embrace technology (Harrington, 2008, p.105).

For example, many employees lose their jobs when manufacturing companies replace them with automated machines that are more efficient and cost-effective. Many families are struggling because of the lack of a constant stream of income. On the other hand, technology has led to the closure of certain companies because the world does not need their services. This is prompted by technological advancements.

For example, the invention of digital cameras forced Kodak to close down because people no longer needed analog cameras. Digital cameras replaced analog cameras because they are easy to use and efficient. Many people lost their jobs due to changes in technology. Thirdly, technology has made people lazy and unwilling to engage in strenuous activities (Harrington, 2008, p.113).

For example, video games have replaced physical activities that are vital in improving the health of young people. Children spend a lot of time watching television and playing video games such that they have little or no time for physical activities. This has encouraged the proliferation of unhealthy eating habits that lead to conditions such as diabetes.

Technology has elicited heated debates in the healthcare sector. Technology has led to medical practices such as stem cell research, implant embryos, and assisted reproduction. Even though these practices have been proven viable, they are highly criticized on the grounds of their moral implications on society.

There are many controversial medical technologies, such as gene therapy, pharmacogenomics, and stem cell research (Hunt, 2008, p.113). The use of genetic research in finding new cures for diseases is imperative and laudable. However, the medical implications of these disease treatment methods and the ethical and moral issues associated with the treatment methods are critical. Gene therapy is mostly rejected by religious people.

They claim that it is against natural law to alter the gene composition of a person in any way (Hunt, 2008, p.114). The use of embryonic stem cells in research is highly controversial, unlike the use of adult stem cells. The controversy exists because of the source of the stem cells. The cells are obtained from embryos. There is a belief among many people that life starts after conception.

Therefore, using embryos in research means killing them to obtain their cells for research. The use of embryo cells in research is considered in the same light as abortion: eliminating a life (Hunt, 2008, p.119). These issues have led to disagreements between the science and the religious worlds.

Technology is a vital component of life in the modern world. People are so dependent on technology that they cannot live without it. Technology is important and useful in all areas of human life today.

It has made life easy and comfortable by making communication faster and travel faster, making movements between places easier, making actions quick, and easing interactions. Technology is useful in the following areas of life: transport, communication, interaction, education, healthcare, and business. Despite its benefits, technology has negative impacts on society.

Technology has eased communication and transport. The discovery of the telephone and the later invention of the mobile phone changed the face of communication entirely. People in different geographical regions can communicate easily and in record time. In the field of health care, technology has made significant contributions in disease prevention and health promotion. The development of vaccines has eradicated certain diseases, and the use of the Internet is vital in promoting health and health care.

The government uses technology to enhance the delivery of services to citizens and the improvement of defense and security. In the education sector, teaching and learning processes have undergone significant changes owing to the impact of technology. Teachers are able to relate to different types of learners, and the learners have access to various resources and learning materials. Businesses benefit from technology through the reduction of costs and increased efficiency of business operations.

Despite the benefits, technology has certain disadvantages. It has negatively affected human interactions and socialization and has led to widespread unemployment. In addition, its application in the healthcare sector has elicited controversies due to certain medical practices such as stem cell research and gene therapy. Technology is very important and has made life easier and more comfortable than it was in the past.

  • 5. ​​The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

1. The Many Uses of Computers

2. can computers take over society, 3. is computer science a worthwhile program to study, 4. pros and cons of computers, 5. can computers compete with the human brain.

“Calculations for things such as automotive design, weather forecasting, and aerospace use supercomputers. Embedded computers are used for functions in a larger product. They are located in things such as automobiles, consumer electronics and office machines. As we all know computers come in many shapes and sizes. They can be used for many different things and can be located anywhere. Technology has increased so much that the most unheard compact thing can be a computer.

Dawson stresses that computers can come in all shapes and sizes. There are different types of computers, such as personal computers, mobile computers, game consoles, and supercomputers, each with its own functions and specialties. He briefly touches on each type of computer and its uses. Technology has come a long way, as the most complex computers are everywhere, whether in laboratories, offices, or even our mobile phones or watches. 

“Critics argue that spell check and other computer features that automatically correct errors in spelling and punctuation make students too lazy to learn and apply the rules themselves. These features, however, help point out where students went wrong and offer valuable learning opportunities that can help students enhance their understanding of appropriate spelling and punctuation.”

In her essay, Barroso discusses the advantages and disadvantages of incorporating computers into education. They allow schools to maximize online resources, foster student engagement, and make it easier for teachers and students to perform school-related tasks. However, they may make students lazy to check mistakes, thinking that the computers will automatically check them. Ultimately, the pros outweigh the cons. 

“As far as I concerned, computer is a great invention and it is useful to human life. It should be impossible to live without computer as we get too much used of computers nowadays. However, we should use it wisely. We know the fact that the more we rely on computer, the more we will lose in our life. So, we should also find ways to make our dependence on computers less dangerous to us, so that we will not rely on computer completely.”

Fox discusses the state of society today where we rely far too much on computers. They help us greatly in our daily lives, but they have made us depend on technology for information rather than thinking for ourselves. And if something goes wrong, like the servers crash, the world is at a standstill. Computers are a net good for society, but we must avoid revolving our lives around technology. 

“In data science terms, this phase is somewhat akin to ‘Model Training’ — the more things a child is exposed to the more the synapses associated with it get built. A good example is language — the more a child is exposed to linguistics in early years, the more evolved the area of her brain that is associated with languages would get. Ditto for other cognitive and non-cognitive abilities.”

Prakash discusses the different ways in which our brains operate as computers. An information processing system has five components: input, output, storage, processing, and program. The human brain does have all of these components, which are used to perform our daily functions. She looks into how human intelligence can be “trained,” like computers are developed. 

5. ​​ The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

“When the brain identifies a more efficient or effective way to compute and function, it can morph and alter its physical and neuronal structure, hence the term “plasticity“. Until we achieve true Artificial Intelligence (in which computers should theoretically be able to re-wire themselves), neuroplasticity will always keep the human brain at least one step ahead of “static” supercomputers.”

Staughton writes about how much more advanced computers have become in recent decades, with some of them being able to outsmart humans in tasks such as chess. However, he explains that our brains are very different from technology and are inherently superior to even the most powerful computers in terms of efficiency, adaptability, and many other factors. However, he keeps the door on computers, eventually developing beyond our capabilities in the future.

  • Essay on Computer


Long and Short Computer Essay

The term computer was once used to refer to a person who did computation, unlike today. The development of early prototypes that led to the modern computer is credited to many individuals throughout history. A series of breakthroughs, beginning with transistor computers and then integrated circuit computers, resulted in the development of transistor technology and the integrated circuit chip, causing digital computers to largely replace analogue computers. 

In this essay, we will discuss the various components and types of computers and talk about their uses in various fields.

Long Computer Essay in English

A computer is an electronic tool that manipulates data or information. It can store, retrieve, and process information. We can type documents, send emails, play games, and browse the Web using a computer. It can also be used to edit spreadsheets, presentations, and even videos, or create them. 

Early computers were conceived only as devices for calculating. Simple manual devices such as the abacus have helped individuals do calculations since ancient times. Some mechanical devices were built early in the Industrial Revolution to automate long, tedious tasks, such as guiding patterns for looms. In the early 20th century, more sophisticated electrical machines performed specialized analogue calculations. 

Common Components of Computers

All those parts of a computer that are tangible physical objects are covered under the term hardware. The hardware includes circuits, computer chips, graphics cards, sound cards, memory (RAM), motherboards, displays, power supplies, cables, keyboards, printers and "mice" input devices.

 There are five main hardware components: 

Input Devices: 

These are devices that are used to enter data/information in the central processing unit. Example- keyboard, mouse, scanner, document reader, barcode reader, optical character reader, magnetic reader etc.

Output Devices: 

These are devices that provide the processed data/information into human-readable form. Example- monitor, printer, speaker, projector etc.

Control Unit: 

The control unit handles the various components of the computer; it reads and interprets (decodes) the instructions for the program, transforming them into control signals that activate other computer parts.

Arithmetic Logic Unit: 

It is capable of performing arithmetical and logical functions. The set of arithmetic operations supported by a specific ALU may be restricted to addition and subtraction or may include functions of multiplication, division, trigonometries such as sine, cosine, etc., and square roots.

Central Processing Unit: 

The ALU, control unit and registers and together called the CPU. It is sometimes called the computer's brain, and its job is to perform commands. We send instructions to the CPU whenever we press a key, click the mouse, or start an application.

Software refers to computer parts, such as programs, data, protocols, etc., that do not have a material form. In contrast to the physical hardware from which the system is built, the software is that portion of a computer system consisting of encoded information or computer instructions.

It is sometimes called "firmware" when the software is stored in hardware that can not be easily modified, such as with a BIOS ROM on an IBM PC compatible computer.

Computer hardware and software require each other, and neither of them can be realistically used on their own. There are four main components of a general-purpose computer: the arithmetic logic unit (ALU), the control unit, the memory, and the I/O (collectively called input and output) devices.

Uses of Computer

Computers are used in various fields, such as homes, businesses, government offices, research organizations, educational institutions, medicine, entertainment, etc. because of their features and powerful functions. They have taken sectors and companies to a whole new level.


Computers are best suited for the collection, analysis, categorization, and storage of data in science, research and engineering. They also help scientists to exchange data both internally and internationally with each other.


Computers in the government sector are used to perform various functions and improve their services. In most cases, data processing tasks, the maintenance of citizens' databases, and the promotion of a paperless environment are the primary purposes of using computers. In addition to this, computers play a key role in the country's defence system.

Health and Medicine- 

They are used to preserve information, records, live patient monitoring, X-rays, and more from patients. Computers assist in setting up laboratory tools, monitoring heart rate and blood pressure, etc. Besides, computers allow physicians to easily exchange patient data with other medical specialists.


They help people get different educational materials (such as images, videos, e-books, etc.) in one place. Also, computers are best suited for online classes, online tutoring, online exams, and task and project creation. Also, they can be used to maintain and track student performance and other data.


Most countries use online banking systems so that customers can access their data directly. People can verify the balance of their account, transfer cash, and pay online bills, including credit cards. Besides, banks use computers to execute transactions and store client information, transaction records, etc.

Short Computer Essay in English

A computer's a programmable device that accepts raw data(input) and processes it as output with a group of instructions (a program) to supply the result. It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating.

Types of Computer

Computers are of different types based on different criteria. Based on their size, computers are of five types:

Micro Computers- 

It is a single-user computer that has less capacity for speed and storage than the other types. For a CPU, it uses a microprocessor. Laptops, desktop computers, personal digital assistants (PDAs), tablets, and smartphones are common examples of microcomputers. Microcomputers are generally designed and built for general use, such as browsing, information search, the internet, MS Office, social media, etc.

Mini Computers- 

Minicomputers are also referred to as "Midrange Computers." They are multi-user computers designed to simultaneously support multiple users. Therefore, they are generally used by small companies and firms. 

Mainframe Computers- 

It is also a multi-user computer that large companies and government organizations use to run their business operations as large amounts of data can be stored and processed. Banks, universities, and insurance companies, for example, use mainframe computers to store data from their customers, students, and policyholders.

Super Computer- 

Among all types of computers, supercomputers are the fastest and most costly computers. They have an enormous capacity for storage and computing speeds and can therefore perform millions of instructions per second.


It is a single-user computer with a comparatively more powerful microprocessor and a high-quality monitor compared to a mini-computer.

Benefits of Computers:

It increases productivity.

It helps in connecting to the internet.

It helps in organizing data and information.

It allows storing large amounts of data.

Fun Facts About Computers

The first electric computer that was invented weighed around 27 tons or even more than that and took up to 1800 square feet.

There are about 5000 new viruses that are released every month.

The original name of Windows was Interface Manager.

It is surely known that the life of humans would not have been so easy if computers were not a part of human life. This is also supported by a lot of pieces of evidence where we can even see in daily life how the computer is not just present in an organization but is also available right in the pockets of everyone. Thus, the computer has surely made it easy while also spoiling a lot of people's lives. 


FAQs on Essay on Computer

1. What are the disadvantages of computers?

Is this AI? See if you can spot the technology in your everyday life.

Tell us what is ai and see how your answers compare to the experts.

Kevin Schaul photo

Artificial intelligence is suddenly everywhere. Fueled by huge technological advances in recent years and gobs of venture capitalist money , AI has become one of the hottest corporate buzzwords.

Roughly 1 in 7 public companies mentioned “artificial intelligence” in their annual filings last year, according to a Washington Post analysis . But the term is fuzzy.

“AI is purposefully ill-defined from a marketing perspective,” said Alex Hanna, director of research at Distributed AI Research Institute. It “has been composed of wishful thinking and hype from the beginning.”

So what is AI, really? To cut through the hype, we asked 16 experts to judge 10 everyday technologies. Try to spot the AI for yourself and see how you compare to readers and the experts.

Is this AI?

Chatbots like ChatGPT

Could be AI

Definitely AI

Experts said

Readers said

We’ll start with an easy one. The viral chatbot responds to a user’s prompt by systematically churning out words, producing a surprisingly coherent but not always accurate reply.

Most experts said that the tool is definitely AI, Things are about to get even murkier.

Auto-correct on mobile phones

Most experts said auto-correct could be considered artificial intelligence, and many said it definitely is AI.

Earlier versions of auto-correct guessed what you meant to type by comparing the locations of the keys you pressed with a dictionary of popular words. But the latest versions also consider the context surrounding a word to better predict what you meant, using the same technique at the core of chatbots. Hint: You’ll see this technology again.

Tap-to-pay credit cards

Not quite. No expert considered tap-to-pay credit cards to be AI. The system uses radio waves to transmit payment information. It sure seems fancy, but it’s not AI.

Google Translate

Eleven of 16 experts surveyed said Google Translate is definitely AI.

Modern translation services don’t simply look up words in a dictionary and return the foreign language match. Rather, the system uses terabytes of multilingual data to build a model of connections between words and their context.

Sound familiar? This technique, called a transformer model , also underlies chatbots and recent auto-correct systems. It provides a more natural, though not always accurate, translation.

Personalized ads

A majority of experts felt it could be AI.

The defining feature of artificial intelligence is that “behavior is learned from data rather than explicitly programmed,” said Matthew Carrigan, a machine-learning engineer at Hugging Face.

For a non-AI approach, a programmer might write specific rules, like, “If a user is a 30-year-old male, show them sports ads.” But AI uses machine learning to create its own rules by analyzing large amounts of data. This enables incredibly specific connections, but it can be difficult to understand how a program drew its conclusions.

Computer opponents in video games

You’re not alone. Few experts today definitely consider video game opponents to be AI.

Chess has long been a proving ground for AI research. AI researchers often test programs through games because they have well-defined rules with clear victors and losers.

In 1980, a Carnegie Mellon professor offered a $100,000 prize for the first computer program to defeat a world chess champion. Seventeen years later, IBM’s Deep Blue beat Garry Kasparov, cementing its place in the history of artificial intelligence.

Beating a world chess champion is no longer impressive. Today’s chess engines dominate all human players.

GPS directions

Turn-by-turn navigation uses a defined set of instructions to search though a database of road networks to quickly find the best route.

How much that route-finding technique just carries out preset rules left experts divided on whether GPS could be considered AI. You said

Facial recognition software, like Apple Face ID

The majority of experts consider facial recognition software to definitely be AI, but you said

The technology maps the precise geometry of people’s facial features. Facial recognition has prompted concern from privacy experts as its use is adopted by governments, especially because the technology is less accurate at identifying people with darker skin.

Apple’s Face ID feature, which lets users unlock their devices by looking at them, projects infrared dots on a face and uses a neural network — a mathematical system that acts like a computerized brain — to determine whether the face matches.

Microsoft's Clippy

You’re in the minority on this one. Most experts said Clippy is not AI, although 1 in 4 said it could at least be considered AI.

The animated paper clip assistant, launched with Microsoft Office 97, offered tips based on what the user was doing, like offering to help format a letter after “Dear Kevin,” was typed. But the widely panned feature was a far cry from intelligence. Microsoft turned it off by default in 2001 and launched a self-aware ad campaign that Clippy was out of work.

Virtual voice assistants, like Alexa or Siri

Just over half of experts consider a virtual voice assistant to definitely be AI.

It can process words as they’re said and handle requests using machine learning and neural networks, which many experts say have become synonymous with artificial intelligence.

Even among experts, what counts as artificial intelligence is fuzzy.

“The term ‘AI’ has become so broadly used in practice that … it’s almost always better to use a more specific term,” said Nicholas Vincent, an assistant professor at Simon Fraser University.

Nothing was unanimously deemed AI by experts, and few products were definitely declared not AI. Most landed somewhere in the middle.

What readers and experts consider to be AI

Some experts don’t think anything we use today is AI. Current technology is “capable of specific tasks they are trained for but dysfunctional at unforeseen events,” said Pruthuvi Maheshakya Wijewardena, a data and applied scientist at Microsoft, who identified no product as definitely AI.

The “capabilities of an AI is a spectrum, and we are still at the lower end,” said Maheshakya Wijewardena.

For Emily M. Bender, a professor of linguistics at the University of Washington, calling anything AI is “a way to dodge accountability” for its creators.

What artificial intelligence generates, whether it’s auto-correct, chatbots or photos, is trained from large amounts of data, often pulled off the internet . When that data is flawed, inaccurate or offensive, the results can reflect — and even amplify — those flaws.

The term AI makes “the machines sound like autonomous thinking entities rather than tools that are created and used by people and companies,” said Bender.

AT&T says a data breach leaked millions of customers’ information online. Were you affected?

NEW YORK (AP) — The theft of sensitive information belonging to millions of AT&T’s current and former customers has been recently discovered online, the telecommunications giant said this weekend.

In a Saturday announcement addressing the data breach, AT&T said that a dataset found on the “dark web” contains information including some Social Security numbers and passcodes for about 7.6 million current account holders and 65.4 million former account holders.

Whether the data “originated from AT&T or one of its vendors” is still unknown, the Dallas-based company noted — adding that it had launched an investigation into the incident. AT&T has also begun notifying customers whose personal information was compromised.

Here’s what you need to know.


Although varying by each customer and account, AT&T says that information involved in this breach included Social Security numbers and passcodes — which, unlike passwords, are numerical PINS that are typically four digits long.

Full names, email addresses, mailing address, phone numbers, dates of birth and AT&T account numbers may have also been compromised. The impacted data is from 2019 or earlier and does not appear to include financial information or call history, the company said.


Consumers impacted by this breach should be receiving an email or letter directly from AT&T about the incident. The email notices began going out on Saturday, an AT&T spokesperson confirmed to The Associated Press.


Beyond these notifications, AT&T said that it had already reset the passcodes of current users. The company added that it would pay for credit monitoring services where applicable.

AT&T also said that it “launched a robust investigation” with internal and external cybersecurity experts to investigate the situation further.


AT&T has seen several data breaches that range in size and impact over the years .

While the company says the data in this latest breach surfaced on a hacking forum nearly two weeks ago, it closely resembles a similar breach that surfaced in 2021 but which AT&T never acknowledged, cybersecurity researcher Troy Hunt told the AP Saturday.

“If they assess this and they made the wrong call on it, and we’ve had a course of years pass without them being able to notify impacted customers,” then it’s likely the company will soon face class action lawsuits, said Hunt, founder of an Australia-based website that warns people when their personal information has been exposed.

A spokesperson for AT&T declined to comment further when asked about these similarities Sunday.


Avoiding data breaches entirely can be tricky in our ever-digitized world, but consumers can take some steps to help protect themselves going forward.

The basics include creating hard-to-guess passwords and using multifactor authentication when possible. If you receive a notice about a breach, it’s good idea to change your password and monitor account activity for any suspicious transactions. You’ll also want to visit a company’s official website for reliable contact information — as scammers sometimes try to take advantage of news like data breaches to gain your trust through look-alike phishing emails or phone calls.

In addition, the Federal Trade Commission notes that nationwide credit bureaus — such as Equifax, Experian and TransUnion — offer free credit freezes and fraud alerts that consumers can set up to help protect themselves from identity theft and other malicious activity.

AP Reporter Matt O’Brien contributed to this report from Providence, Rhode Island.

essay about computer in daily life


RNA that doesn't age

Neuroscientists at fau discover building blocks in nerve cells that last a life time.

Certain RNA molecules in the nerve cells in the brain last a life time without being renewed. Neuroscientists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now demonstrated that this is the case together with researchers from Germany, Austria and the USA. RNAs are generally short-lived molecules that are constantly reconstructed to adjust to environmental conditions. With their findings that have now been published in the journal Science , the research group hopes to decipher the complex aging process of the brain and gain a better understanding of related degenerative diseases.

Most cells in the human body are regularly renewed, thereby retaining their vitality. However, there are exceptions: the heart, the pancreas and the brain consist of cells that do not renew throughout the whole lifespan, and yet still have to remain in full working order. "Aging neurons are an important risk factor for neurodegenerative illnesses such as Alzheimer's," says Prof. Dr. Tomohisa Toda, Professor of Neural Epigenomics at FAU and at the Max Planck Center for Physics and Medicine in Erlangen. "A basic understanding of the aging process and which key components are involved in maintaining cell function is crucial for effective treatment concepts:"

In a joint study conducted together with neuroscientists from Dresden, La Jolla (USA) and Klosterneuburg (Austria), the working group led by Toda has now identified a key component of brain aging: the researchers were able to demonstrate for the first time that certain types of ribonucleic acid (RNA) that protect genetic material exist just as long as the neurons themselves. "This is surprising, as unlike DNA, which as a rule never changes, most RNA molecules are extremely short-lived and are constantly being exchanged," Toda explains.

In order to determine the life span of the RNA molecules, the Toda group worked together with the team from Prof. Dr. Martin Hetzer, a cell biologist at the Institute of Science and Technology Austria (ISTA). "We succeeded in marking the RNAs with fluorescent molecules and tracking their lifespan in mice brain cells," explains Tomohisa Toda, who has unique expertise in epigenetics and neurobiology and who was awarded an ERC Consolidator Grant for his research in 2023. "We were even able to identify the marked long-lived RNAs in two year old animals, and not just in their neurons, but also in somatic adult neural stem cells in the brain."

In addition, the researchers discovered that the long-lived RNAs, that they referred to as LL-RNA for short, tend to be located in the cells' nuclei, closely connected to chromatin, a complex of DNA and proteins that forms chromosomes. This indicates that LL-RNA play a key role in regulating chromatin. In order to confirm this hypothesis, the team reduced the concentration of LL-RNA in an in-vitro experiment with adult neural stem cell models, with the result that the integrity of the chromatin was strongly impaired.

"We are convinced that LL-RNAs play an important role in the long-term regulation of genome stability and therefore in the life-long conservation of nerve cells," explains Tomohisa Toda. "Future research projects should give a deeper insight into the biophysical mechanisms behind the long-term conservation of LL-RNAs. We want to find out more about their biological function in chromatin regulation and what effect aging has on all these mechanisms."
