Many yearly rituals of Ramadan will continue even as some change in deference to our social responsibility to respect God’s laws in the universe. 

The Muslim holy month of Ramadan will be different this year. Around the world, mosques will be closed, when they would normally have worshipers spilling out onto the street. Extended families will remain apart, when they would typically gather for Iftar to break the fast and share homemade treats. And shopping malls, cafes and streets will be eerily quiet, when they would normally come alive after dark.

Ramadan still began on Thursday evening, though, and in the early hours on Friday morning, households gathered, as they have for centuries, to share a sleepy suhur — the pre-dawn meal.

Even as the world grapples with COVID-19, the yearly rituals of Ramadan will continue. Throughout the holy month, most of the world’s 1.8 billion Muslims will fast between dawn and sunset, spend time in Quranic recitation, self-reflection and prayer in an effort to become closer to God, and give thanks for our blessings. But this year, the prescribed exceptions from fasting for young children, travelers, pregnant mothers and anyone who is sick will now be extended to those feeling symptoms of COVID-19.

And this year, our prayers will include special emphasis on the health care workers, emergency workers and other essential employees who are on the front lines of the fight to protect our communities. In the eyes of God, saving human lives and benefitting humanity are most noble endeavors: The Quran likens saving a life to saving the whole of humanity, and the Prophet Muhammad (upon whom be God’s peace and blessings) says that the best of humans are those who benefit other humans.

Our obligation to help and support those in need also takes on added meaning this year as our neighbors and communities face sickness, grief, economic hardship and the loneliness of self-isolation.

Perhaps the most difficult obligation for many, though, will be forgoing the long-planned gatherings of the season, in order to comply with precautions issued by authorities. But following these measures is a duty of our citizenship and a necessity of our social responsibility to respect God’s laws in the universe. For instance, the Prophet Muhammad — whose belief and trust in God was beyond description — even advised quarantining a town in the event of an infectious disease.

Each of us should take the extra time and space afforded by the pandemic’s social distancing measures as an opportunity for further examination of our connection with God, our families and our core values. This time offers a mandatory retreat from the busy nature of our daily lives and a chance to turn toward God, deepening our faith, knowledge and practice. I hope that imams will offer reminders about these opportunities to their congregations.

This period also forces us to rely on the internet and the technologies built upon it. Our young generations have been well-versed in these technologies ahead of their parents. Throughout history, messengers of God and those who strive for the enlightenment of humanity always used the available cultural tools and practices to spread their messages. We also must take this time to connect with our communities in new ways, including making our spiritual resources accessible to younger generations using their language and their familiar technologies.

The challenges of responding to the pandemic and altering our lives might push some of us to seek people to blame or to criticize. As we enter Ramadan, it is paramount that we devote ourselves to helping those in need, rather than finding others to blame. Even as people, groups or nations with whom we have had past differences may be suffering, each of us must reject as inhumane the thought that anyone deserved a calamity.

In a globalized world, nobody is isolated from a potent problem, be it environmental, medical or economic. This is a time to share data, and to collaborate to find solutions. This is a time to realize our interdependence as nations, as communities and as inhabitants of a global ecosystem — a time to recognize that we all are members of the human family and each have the opportunity to show the true potential of humanity.

As we enter this holy month, it is crucial that we look forward with hope and not despair, which stifles people and progress. Humanity has overcome great challenges in the past, and we will find ways to overcome this challenge, too. If we focus on the opportunities this pandemic presents, we will be able to keep our spirits high and reach the end of this tunnel much quicker.

Our observance of Ramadan will necessarily be different this year. But in many ways it will be like any other year: We will fast, we will pray, we will recite our holy book and we will take time for reflection and charity throughout the holy month. May God enable us to benefit fully from the feast of bounty in Ramadan.

There are already 1.5 billion smartphone users and a total of 5 billion mobile phones in the world. Smartphone companies are announcing new phone models with improved capabilities every year. These are smarter and better phones with new sensors, powerful chips, and new capabilities. Newspapers and technology blogs often start discussing rumors about an upcoming smartphone several months before its launch.

Over the past few years, we have seen many futuristic prototypes and designs. Consumers request better and smarter phones that can handle more and more tasks with every new model. Although the phone companies are surprising us with new smartphones every year, we are far from seeing some of the technologies presented in prototypes. What do you expect to see in smartphones in the next 5 to 10 years? Let’s talk about some of the technologies that will end up in a smartphone in the near future.

One of the critical components in a smartphone is the battery. While most smartphones only support being charged from a wall plug, some of them are supporting inductive wireless charging out of the box. Although it is not a standard feature for most smartphones, wireless charging can be enabled using third-party cases and charging pads. Current wireless charging systems still require the smartphone to be placed on a pad for charging. A bigger step in powering smartphones will be touchless wireless charging. A new startup company, Ossia [1], recently unveiled the world’s first commercially viable touchless remote wireless power system. Imagine you are walking into your house or office, and the smartphone in your pocket is starting to charge via receiving electric waves through the air.

With wired or wireless charging, the battery technology of smartphones remained largely unchanged for years. A large percentage of smartphone bodies are occupied by lithium-ion batteries. With the developments of new power efficient displays and computing chips, smartphones are now using less and less power. This allows manufacturers to use smaller batteries with the same usage time. Battery technologies are not efficient enough to power smartphones more than a couple of days with average daily usage. People often carry extra batteries and chargers when travelling or spending time outside. Solar charging can help with some of these challenges by enabling smartphones to recharge under sunlight. Researchers are also exploring other materials to replace lithium-ion (e.g. graphene) in batteries to provide extra power for the ever-growing size of smartphone displays.

Smartphone displays are getting bigger and better with ultra-high screen resolutions that are sometimes even stronger than the human eye. Some manufacturers are already working on 4K ultra HD displays (3840 pixels wide by 2160 pixels tall). With the screen sizes getting larger, the distinction between a smartphone and tablet is becoming less clear. Some smartphones are even called phablet, a new category between smartphones and tablets, by newspapers and tech blogs.

A bigger jump in display technology will be through the use of flexible screens. There are already prototypes of 5-inch flexible displays or 50 inch curved televisions from several companies. One benefit of flexible displays would be fitting a tablet size screen on a small smartphone body. Users will be able to slide or unfold the display of a typical size (e.g. 4-inch) smartphone, and convert it to an 8-inch tablet. Companies are still looking for a good use case for flexible displays in daily life. Some applications of the smartphones with flexible displays make them closer to wearable devices. Some of them have appeared as watches or bracelets.

Another development in display technology is transparency. There are already prototypes of transparent displays in various sizes and forms. Transparency is important for heads-up displays and some models where seeing the background is necessary. This technology will allow displays on glasses, contact lenses, windows, and windshields. An obvious application of the transparent displays in cars is a GPS navigation system on the windshield [2]. This will open a full immersive experience by showing directions directly positioned on the road, virtual signs on the sidewalks, and even augmented information about companies and addresses directly on the walls of the buildings. Imagine seeing a large virtual menu or information panel with available seats, business hours, and prices on the wall of a restaurant. While the transparent displays are already available in various prototypes, the main challenge is achieving transparency in electronics and other components in a smartphone.

Even with flexible displays, you may not be able to carry and fold a 50-inch display into typical smartphone size. A major shift from increasing the display size will come via the use of pico-projectors. A smartphone, with a decent display size (e.g. 5 inch) for everyday use, can be turned into a full size (e.g. 50-inch) media consumption system with an integrated pico-projector. Although there are prototypes of pico-projectors embedded into smartphones, there are still many technical limitations in projection size, brightness, battery life, and cost of components.

While larger displays provide a better experience for users, the consumable content is mostly 2-dimensional. Even though there are games and movies designed and recorded in 3-dimensional environments, they still cannot provide a true 3D experience. All of this 3D content is projected onto a 2D screen in smartphones. There are prototypes giving the 3D effect by providing 2 separate images to both eyes by using a stereoscopy or parallax barrier. These technologies have limitations in field of view, viewing angle, interactivity, and distance of viewer. Researchers can create a pseudo 3D experience via head tracking, using camera or sensors to provide a glass-free experience. This allows users to see a different perspective of the scene on the phone by looking from different angles. The technology is still in its early steps with limited applications and hardware support for the full immersive experience and interaction.

The keyboard is main point of interaction in smartphones. One of the major changes in smartphones was eliminating the physical keyboard on the phone. Now most of the front face of the phone is covered with the display. Multi touch displays provide on-screen keyboard for text input. While they are similar in size, on-screen keyboards allow customization for different languages, use cases, and applications. On-screen keyboards try to imitate the haptic feedback through vibrations, but still cover almost half of the screen during typing. There are prototypes with air-inflatable buttons in real 3D forms using a transparent layer on the screen to provide realistic haptic feedback. The size of the keyboard is the main limitation for smartphones. A new prototype eliminates even the on-screen keyboard using laser projection. A small device projects a full size virtual keyboard on a flat surface like table using lasers, and tracks finger movements for recognizing key inputs. This allows both customization and experience of a full size keyboard, while making the screen fully available for other functions on the phone.

While the main input point for the phone is through virtual or on screen keyboards, a smartphone actually gets many inputs from outside through sensors. The full potential of these phones can only be achieved through new technological sensors in the phone. GPS and compass sensors allow navigation and direction capabilities, and replace the need for a GPS device for most users. Many smartphones are now listed as the most used camera devices on photography websites, and are getting closer to the quality of a DSLR camera with new image sensors. Proximity sensors understand the distance between device and user, and allow the device to turn off the display during phone calls to reduce battery usage. Accelerometer and gyro sensors provide new inputs for gaming and user interaction. Barometer, temperature, humidity, gesture, fingerprint, and heart rate sensors are becoming part of many smartphones. Researchers are already experimenting with ultrasound [3] and x-ray scanners [4] for smartphones, and we are getting one step closer to the Star Trek tricorder, a general-purpose science fiction health diagnosis device.

The future of smartphones is almost unlimited. We have already seen novel technologies introduced for smartphones as prototypes and concept designs. We can easily extend the list with intelligent assistants, nano-coating for waterproofing and self-cleaning, seamless integration of voice controls and augmented reality, environmental and medical sensors, and 3D and holographic displays. I can’t wait to see some of these technologies integrated into smartphones in the near future.

While smartphones revolutionized the way we communicate and how we carry out many of our daily tasks, at the same time they are challenging our privacy, safety, behavioral codes, social life, and the use of public space. The problems and discussions will not end here, and they are growing with the introduction of new sensors and capabilities. Increasing awareness through education about the security and privacy risks that smartphones present is the first step for protecting users from future problems. Parents and educators have a critical role for raising responsible generations, and they can start with becoming a good role model [5] on how they use their smartphones…

Will there be wars over elements like there have been over petroleum and water? What element have we been using in color televisions? What substance is used to make energy saving, environmental light bulbs?

Each of the elements found in the periodic table have their own characteristics. After they have been cooked in the pot of the universe, these substances that are offered to our service can be radioactive (like uranium), metallic (like magnesium) and even gaseous (like helium). Seventeen of the elements not easily found among the layers underground have unique properties. These elements are called rare-earth elements, because it is hard to discover and mine them.

Rare-earth elements are in many of our everyday devices. The data projected on a computer screen is transmitted via optic cables containing erbium. The light of a tablet device is generated by the phosphorescent element europium. We actually touch indium covered surfaces when we scroll our fingers on touch screen monitors. When listening through headphones, we are using neodymium magnets that are ten times stronger than iron magnets.

From space technologies to defense industries, from cell phones to LED lighting, many such rare-earth elements are used in every stage of our lives. These elements – many of which we cannot live without, even though we’ve never heard of them – were recorded into the Critical Materials Strategy Document published by the U.S. Department of Energy in 2010. In a public announcement, the department declared fourteen of the elements as specially significant regarding clean energy, listed six of them as critical, and the other four as near critical. Fifteen elements, beginning with lanthanum and ending with lutetium, numbered between 57 and 71, comprise lanthanides. Combined with scandium and yttrium, these make up the seventeen rare-earth elements.

The elements that we touch on screens

Indium (atomic number 49) gains the properties of electrical conductivity and optic transparency when combined with tin, which, at number 50, is indiums’s neighbor on the periodic table. Optical transparency is a desired property for plasma screen and television technologies. Indium is also an important material for mobile phone touchscreens. Interestingly, when indium combines with cadmium, also as a neighbor at number 48, it loses the optical transparency. Instead, it is able to absorb light. Light harvesting is a very critical feature in the production of solar cells.

The relationship of indium with its two neighbors opens new horizons for scientists. In the near future, it is hoped that many unknown and interesting features will be unearthed by investigating the known elements of the periodic table. It is amazing that these elements have been around for thousands of years in the universe only to be discovered by technological advancements.

The need for rare-elements in the world is around fifty thousand tons. The current recorded reserve for rare-earth elements is 110 Million tons. Currently, 95% of the demand for rare-earth elements is supplied by China, yet the country only has 35% of the world’s reserves. Therefore scientists are constantly searching for rare-earth element mines to eliminate the Chinese monopoly and to boost the production of these rare materials. In recent years, China has gotten into political debates with Japan and the United States by curbing rare-earth element exports. Economic journals covering these debates wondered if “element wars” were near. In 2010, a massive reserve of elements, enough to sustain worldwide demand, was discovered in the Pacific Ocean. Developed countries are now planning to recycle rare-earth elements from used devices due to low reserves.

Yttrium, europium, and terbium (atomic numbers 39, 63 and 65) have been known for a long time. Terbium and yttrium are named after the Swedish town of Ytterby. Yttrium is the first rare-earth element discovered, at the end of 18th century. Plastics containing europium are used to make laser products; it’s also used as an element to provide the red color on television screens. Yttrium has a supplementary role that enhances europium’s red color production. And terbium oxide activates the green phosphorescence of television tubes with its yellow-green phosphorescent property.

Terbium also enables an 80% reduction of energy consumption in light bulbs. This makes it one of the most wanted elements in the $2 billion rare-earth element market. Today, when we purchase class A type light bulbs, we are actually buying rare elements like terbium.

Neodymium (number 60), which emits a green light via laser pointers, is also used in the magnets of electric motors. When neodymium combines with boron and iron, it makes a magnet twelve times stronger than simple iron magnets. Because it is significantly less dense than iron, it makes electric motors and laptop computers much lighter. Another interesting feature of neodymium is that it enhances the data storage capacity of hard drives. Furthermore, neodymium is wanted for electrical devices and wind turbines.

The union of elements

Dysprosium was discovered in 1886 and can never be found in a free form in nature. This is because it exists in a compound form with other minerals, like gadolinite. Dysprosium is also known for its magnetic property, and when mixed with terbium and iron, it forms a substance called Terfenol-D. In a magnetic field, Terfenol-D has unique transformational abilities. Dysprosium is utilized in laser production together with vanadium, and it emits infrared radiation when used with cadmium.

The magnetic alloys of iron, boron, and neodymium lose their magnetic features beyond 300 degrees Celsius. However when this alloy is combined with dysprosium at a 5% ratio, that problem disappears. Therefore, these magnets are used for electric turbines and hard disc motors. Dysprosium also makes magnets in electric motors 95% lighter. And dysprosium and nickel mixed fillings are used as cooling rods in nuclear reactors.

The human mind becomes fascinated after seeing all the wisdom and properties involved in these lifeless elements. Either we conclude that these elements have doctorate degrees in physics and chemistry from Harvard University, or we may express our weakness and fascination in front of The Grand Creator who created and presented these elements for our benefit.

Is the yellow color in glasses from the planet Ceres?

Since Dell recalled four million laptop computers in 2006, because of a possible explosion caused by overheating battery, scientists’ eyes have been focused on lanthanum and cerium. These two elements are considered to be safer than other alternatives. Lanthanum and cerium are used in electrical equipment and energy saving light bulbs, and are classified as critical elements in these processes, along with tellurium. Cerium, named after the planet Ceres, is responsible for the yellow coloration in glasses. Cerium is also used in polishes, ceramics, and petrol refineries. Tellurium is produced indirectly, unlike most other elements. The production of cadmium takes place during zinc production, and tellurium during copper refining. Tellurium is a cheaper element that has been used in combination with cadmium on solar cells since 2009; before then, most solar cells used expensive silicon panels.

Elements in our lives, from space rockets to ultrasound imaging

Hafnium, tantalum, erbium, and technetium are important elements, even though they are not listed critical. Even though hafnium and technetium are not rare-earth elements, they were still added to the critical material strategy document produced by the US Department of Energy. Hafnium is employed in space rockets for its resistance against extreme temperatures and wearing. Hafnium oxide is a valuable material for electronic transistors since it is a very effective electric insulator. It is 20% faster than the silicon oxide that is commonly used in transistors. A transistors length is around 65 nanometers when silicon oxide is used, but it is only 32 nanometers with transistors made of hafnium oxide. This 50% decrease enables smaller devices.

Touchscreens containing indium, laptop computers powered by lithium ion batteries, and cell phones with hafnium transistors are some of today’s technological wonders. Would these inventions still be possible without these elements? Could we reach the high capacities in hard discs without the tantalum? Would we be able to protect ourselves from electric leakage in computers without high quality electric insulators such as tantalum oxide?

Radioactive technetium, which was discovered in 1937, is the first artificially produced element. The technetium 99 isotope is used in nuclear medicine. Technetium produced from uranium has a half life of 211,000 years, as opposed to the 6 hour half life of the technetium 99 isotope. The number of technetium based nuclear medicinal tests, like ultrasounds and x-ray imaging, is estimated to be above thirty million annually.

We take advantage of these elements in every stage of our lives, from medicine to technology. Could we become dependent upon elements the way we are upon petroleum? Only time will tell. Either these elements will be replaced by other materials, or other technologies will outdate the current technologies. It is also possible new elements will be discovered.

A majority of our modern technologies would not exist without these elements that were dispersed among the earth billions of years ago. These elements were placed here for our benefit, and so we could utilize them, and produce institutes of scientific research and education to study them.

It was only a decade ago that a phenomenon called the “Internet” came along and changed the way we communicated, did business and conducted our lives. Now, computer technology has become an essential and significant part of our daily lives. But how did it all start and where is it heading?

I entered the world of computers at an early age. I had an Atari 800 XL, the third version of the Atari introduced in 1983, and I was doing some basic programming. The computer contained a full 64K of memory, 1.8 MHz processing power (CPU), and looked like a bulky keyboard. I enjoyed spending a lot of time with games and programming; however I felt very limited with its capabilities. After more than 20 years, from time to time I still feel the same about my 2.8 GHz eight-core desktop computer with 8 GB of memory. While the computers are getting faster and more powerful, our need for computing power is also increasing just to complete our daily tasks at home and work. I always wondered how it all started and where we are heading with computer technology.

Over forty years ago, Gordon Moore, Intel Co-founder, predicted the number of transistors incorporated in a chip to double every 24 months. This is popularly known as Moore’s law, and used countless times by futurists [1] and science fiction writers. For the last half century, computer’s functionality and performance increased in line with Moore’s law, while costs are decreasing. However, fundamental barriers in semiconductor technology are emerging including the power needs and limits of manufacturing in atomic dimensions. Computer industry is already working on technologies to keep Moore’s Law alive.

Intel is already experimenting with 3D transistors that are smaller, faster and more energy efficient using a 22nm (nanometer, 10-12 m) manufacturing process compared to today’s 32nm systems. This will be a significant step forward to build more transistors onto silicon chips. Another approach will be by replacing the silicone in transistors. In 2010, IBM showcased a graphene transistor running at 100 GHz, with a potential of up to 1000 GHz. A graphene layer is only one atom thick with a honeycomb-like structure of carbon atoms. The graphene has unique electrical, optical, mechanical and thermal properties with promising applications in many industries.

In 1971, a theoretical prediction was made for the missing link in electronics, memristor, a fourth element to supplement resistor, capacitor and inductor, which form the basis of today’s electronic devices. HP’s demonstration in 2010 shows a resistor with memory that remembers the electric voltage applied even when the power is turned off. Requiring very little energy to store information promises to run ten times more power efficient and ten times faster than current counterparts.

In 1994, Leonard Adelman [2] proposed DNA computing to solve the famous, “shortest path problem”. Since then, many approaches have been made to utilize the properties of DNA for computing. In 2010, researchers at California Institute of Technology demonstrated a DNA computer, most advanced to date, which can calculate square roots. This approach could be put in use inside living organisms, and perform vital tasks such as disease detection. The promise of DNA computers depends on the parallel processing capabilities of DNA molecules that can try many possibilities at once with low power requirements [3]. Further advancements in DNA based computers in the coming decades will bring faster and low-powered computers to our daily lives.

In 1981, the famous physicist Richard Feynman speculated the possibility of computers obeying quantum mechanical laws that might best simulate the real-world quantum systems. This is a big challenge even for today’s fastest supercomputers. Since then, researchers are pacing towards building quantum computers that rely on quantum mechanics to conduct operations. Quantum computers can use properties like entanglement [4] and qubits. In entanglement, particles behave identically independent of the distance between them, and qubits act as both memory and state of the entanglement. Shor’s Algorithm, formulated by Peter Shor in 1994 for prime factorization is a powerful example of quantum computing that allows breaking encryption algorithms like RSA encryption more effectively and quickly than today’s super computers. Quantum computers can perform at much higher speeds than traditional computers, and are able to solve more complex problems. Recent developments in quantum computing such as quantum photonic chips [5], and first commercial quantum computer by D-Wave shows that we might be closer than we think to have our very own quantum computer in the coming decades.

While greater shift in computing might stem from the change in underlying technology in processing the information, computer form factors (desktop, laptop, tablet, phone, etc.) have a more direct effect in our daily use of computers. Human computer interaction changed significantly with the introduction of smartphones (e.g. iPhone, Android phones), and tablets (e.g. iPad), moving from keyboards and mouse as the primary input methods towards touch screens.

Today’s touch screens, although providing infinite ways of input structures available on their screens, lack tactile feedback when compared to keyboards. New keyboard designs with small screens on each key opens infinite customization of the input, but are still limited to initial design of the key (e.g. usually cubic). Recent developments in touchscreen designs enable users to feel clicks, vibrations and other tactile input by using “haptic technology”. Haptic technology takes advantage of the user’s sense of touch and provides feedback by applying forces, vibrations, or motions to the user. As seen in early prototypes, flexible screens and electronics will provide a more realistic feel for human computer interaction by shifting their forms to a specific shape (e.g. game pad, key, and wheel) in the coming decades.

Another level in human computer interaction even eliminates user’s touch. Apple introduced Siri, a smart virtual assistant, in 2011 as a part of their iOS operating system for iPhones and iPads. Siri is capable of analyzing user’s complex audio inputs to carry out many tasks including scheduling a meeting, creating a reminder, typing and sending SMS messages, and many other functions available in smart phones. Microsoft introduced Kinect in 2010, a motion-sensing device that enables users to control and interact with the game console using gestures and spoken commands. The Kinect interprets specific gestures by using an infrared projector and camera to track the movement of objects and individuals in three dimensions.

Samsung introduced a 46’’ transparent display using LCD technology in 2010, and demonstrated flexible displays in CES 2011. Transparent and flexible displays will easily find use in wearable electronics such as contact lenses and glasses. An obvious application of transparent display is Augmented Reality (AR) where information is displayed on top of real world images. While today’s smartphones and tablets allows augmented reality by combining information with the real-time video feed from the camera of the device, transparent display eliminates the need of using camera. Current AR technology includes head-mounted displays and virtual retinal displays for visualizing the information. It is widely applied in various areas including entertainment, advertising, game industry, navigation, education, military applications, and information sharing.

While having larger, transparent, and flexible displays in different forms, one direction in display technologies is to reduce the size or even eliminate the display through projection and holograms. Current trends in projectors include 3D projection, synchronization of multiple projections, and pico projectors. The world’s smallest glass lens (1mm x 1mm) introduced in 2011 will help minimize some of the problems of projectors such as size, power and heat, and improve their integration in smartphones and tablets.

Recent prototypes of holographic displays progressed significantly demonstrating 3D and full color animated images, since its first introduction at the MIT Media Lab 1989 [6]. While developments in 3D displays are promising, holography provides the best 3-D experience since it is closest to how we see our environment. A hologram uses an optical effect called “diffraction” to produce the light that would have come from an object, and makes the image of the object appear in front of the viewer. It is possible to view objects from different angles in holographic display by walking around them. Unlike other 3D display systems, holographic displays do not require special glasses for viewing and allows multiple viewers to experience the view from different angles at the same time. Future applications of holography can be implemented in health, entertainment and communication sectors, from 3D movies to telepresence applications.

All of the above examples and trends in computers deal with the computing as a product. Cloud computing can be defined as the delivery of computing as a service where shared resources, software, and information are provided over a network. Cloud computing describes a new delivery and consumption model that allows dynamic scalability and virtualization of resources. Users can dynamically upgrade the storage and computing power from virtualized resources on demand without hardware changes on the base system. Organizations can save from investing on expensive hardware, and human capital.

Many technologies from coming centuries are featured in science fiction books and movies such as Minority Report, Star Trek, and Star Wars. While some of them are already available to consumers, others might require decades to come. Motivation for the advancement in computer technologies usually stems from our needs and desires. At the same time, new technologies significantly impact consumer behavior and increase our dependence on new technologies. Our economy is structured such that all citizens have to consume more and more, even if that means disposing of perfectly good technological devices. Do we really need a new computer or phone every year? Most of us don’t.

Computer technologies are a significant part of our daily lives, and the line between the products and services is becoming thinner with the dependency on computers increasing in every aspect of our life. While improving the quality of our lives by making our daily tasks easier, computers and Internet technologies can affect us in different ways. It has already started to change how we read, write and even communicate with others. Many concerns are raised about the negative effects of the use of technology including Internet addiction, privacy, attention span, concentration, time consumption, anxiety, isolation, depression, digital security, communication disorder and various health issues. The challenge for us is to understand the benefits of the technology, have a balance in dependence and its use, and protect ourselves from its adverse effects.
