Augmented and Virtual Reality The Promise and Peril of Immersive Technologies

Augmented and Virtual Reality The Promise and Peril of Immersive Technologies If you keep up with technology news even slightly, you have probably heard about augmented and virtual reality.Even if you rarely follow tech news, you have probably heard about Oculus Rift or Samsung Gear VR.Truth is, there has been a lot of hype about augmented and virtual reality over the last couple of years, with the two touted to be the technologies that will replace mobile computing.Over the last three to five years, a lot of companies have brought various VR and AR products to market. There have also been a lot of investments into this technology.In 2014, Facebook paid $2.1 billion to acquire Oculus VR, a company that manufactures virtual reality headsets.Facebook then went on to buy 11 other VR and AR startups, showing the social media giant’s belief that AR and VR will have a key role to play in the future of computing.While the industry is still in its infancy, it is expected that by 2025, the AR and VR industry will be worth about $95 billion, according to estimates by Goldman Sachs.At the moment, a lot of the interest in AR and VR technologies is coming from a handful of industries, such as gaming, video entertainment, live events and retail.As the technology matures, however, it could potentially revolutionize a wide range of industries, including education, healthcare, real estate, the military, and so on. Source: McKinseyIn this article, we are going to take a look at some of the potential impacts of AR and VR technology, as well as some of the challenges that the technology might face.WHAT IS THE DIFFERENCE BETWEEN VIRTUAL AND AUGMENTED REALITY? There is a lot of confusion about the two technologies, which can be attributed to the fact that the two technologies gained prominence at about the same time and that both involve altering reality in some way.Despite these similarities, there are some key differences between virtual reality and augmented reality.Virtual reality is a technology that totally replaces the real life environment with an artificial simulation of reality.With virtual reality, a user wears some closed VR goggles or headgear â€" such as the Samsung Gear VR, Oculus Rift or Google Cardboard â€" which blocks out your current environment and immerses you in a very realistic looking and convincing.The user feels like they are part of the artificial world instead of the re al world.Augmented reality, on the other hand, does not try to replace reality. Instead, it tries to enhance reality by using technology to layer useful or entertaining digital information over your real world.Examples of information that may be layered over your real world through AR tech include maps, text-based directions, virtual characters (in the case of an AR-based video game), emails, a reminder about a scheduled task, and so on. AR does not interfere with your perception of reality.HOW VR AND AR WILL IMPACT THE CREATION AND CONSUMPTION OF CONTENTVirtual and augmented reality will impact how we create and consume content in four ways. These include:Shifting Content Consumption from Observation to ImmersionFor a long time, the only option we had when it comes to consumption of content is observation. When you watch a video on your phone or a movie on your TV, you are basically observing what is happening on the screen.Even with video games, while you have control over what is happening on the screen, you can still easily distinguish between your real world and the virtual world within the game.Attempts have been made to make this observational consumption of content more immersive.For instance, 3D movie technology was developed to make viewing movies more immersive, but there is still a clear distinction between reality and what is going on in the screen.AR and VR technology has brought about a new way of consuming content.Rather than observing content from our reality, we become part of the reality that is on the screen.When you step into a virtual world through a VR headset, all your perceptions are based on the virtual world.You become part of that world and for a moment, you forget about the real world. With augmented reality, the virtual world becomes part of your reality.It seamlessly integrates your real world and virtual data into one.This will make consumption of content a totally new form of experience.Reducing the Cost of Production in Creati ve ActivitiesVirtual and augmented reality will enable something known as virtual prototyping, which allows products under development to undergo several iterations while keeping time and costs low and improving the quality of the final product.A good example of this application of AR and VR technology is an aeronautical design firm that used VR prototyping to bypass two physical prototyping cycles and reduce the time it would have taken to complete development, resulting in savings in excess of $50,000 for the client.Another good example of the use of virtual prototyping is IKEA’s use of augmented reality to enhance the shopping experience for furniture shoppers.Instead of buying a piece of furniture based on your mental image of your home and hoping that the piece of furniture will not only fit within the available space, but also look good in your home, you can simply scan the space with your smartphone camera and then layer different pieces of furniture over this scanned image to find the best piece of furniture for your space.Of course, virtual prototyping is not a new thing.However, AR and VR technology takes virtual prototyping a notch higher, making the process more immersive and increasing the number of ways through which designers interact with and experience their prototypes.This will result in reduced cost of production, higher accuracy in design and an improvement in overall product quality.Making it Easier for New Creators to Get StartedIn the past, producing quality content was an expensive affair, something that kept it out of the reach of small firms with lower budgets as well as hobbyists.Fortunately, AR and VR technology is making it a lot easier to produce high quality content at a low cost.This lowering of costs will make it a lot easier for new creators to get into the market, the same way smartphone cameras made it easier for new creators to get into photography, videography, vlogging, and so on.Acting as a Tool for Cognitive Enhanceme nt and EmpathyBy putting us at the center of the experience rather than being mere observers, virtual and augmented reality make us feel as if we are part of the reality being depicted in the content being consumed, and therefore evokes a greater level of empathy and allows us to feel closer to global issues.For instance, if you consumed content about a humanitarian crisis through VR, you would feel greater empathy for the victims, because it feels like you are there with them.This is because with virtual and augmented reality, there is a layer of authenticity of experience that is not present with other content consumption mediums, according to artist and director Lynnette Wallworth.In the past, there have been concerns that increased digital media consumption could lead to decreased ability to feel empathy.However, artists who have worked with virtual and augmented reality technologies feel that these technologies will enhance our ability to feel empathy, terming AR and VR technol ogy as the ultimate empathy machine.In addition, AR and VR technology will contribute to cognitive enhancement by providing opportunities for immersive learning experiences.In addition to gamified learning, AR and VR technologies can also be used in therapeutic domains.For instance, in one case, AR and VR technology was used to allow a man to drive a car using nothing other than his brain. You can view the video here.CHALLENGES FACING VIRTUAL AND AUGMENTED REALITYWhile virtual and augmented reality will bring about the positive impacts discussed above, there are also some challenges that will need to be overcome if the potential of this technology is to be fully harnessed. These include:Shortage of Talent is Limiting GrowthWhile there are technical challenges facing this technology â€" including battery life and bulkiness of devices â€" probably the greatest barrier preventing the rapid advancement of virtual and augmented reality technology is the lack of adequate talent to push th is advancement.Being a relatively new technology, it is difficult to accurately show the disparity between the demand and supply of talent.However, there’s some evidence to this effect. For instance, data from Bloomberg shows that in the second quarter of 2017, there was greater growth in demand for freelancers with VR skills than for any other skill.Yet another study of 200 Canadian companies with a focus on AR and VR reported that companies in this industry will experience a talent crunch in the near future.Strategic Development of Domestic TalentAny government that wants to be part of the countries that will lead the march into the next frontier of computing needs to start coming up with a strategic plan that will ensure the development of talent in emerging technologies.Some countries have already started doing this.A good example is China, whose government has already put in place measures to support the growing VR industry.For instance, VR companies in Zhongguancun, Beijing, are receiving government subsidies to the tune of up to $1.45 million.The aim is to have this region grow into a technological hub that will spearhead the VR industry globally. Companies in other locales in China are also receiving grants from the government to support the development of VR-related content and hardware.Attracting Foreign TalentAside from developing content, governments that want their countries to become leaders in the next frontier of computing also need to put greater focus into funding development of immersive content.According to a 2016 survey by the UBM Game Network, more than half of companies in the AR and VR industry use their own funds to fund projects. Only less than 8% of companies reported having raised funds from “other” sources such as the government.The problem is that VR and AR development is a costly affair. Costs associated with VR projects often run into hundreds of thousands of dollars, something that keeps out a lot of people from venturing into VR development.To encourage more and more people to get into the AR and VR industry, governments can come up with policies that give subsidies and grants to companies involved in immersive content.This will attract VR companies and talent from all over the world.Already, some governments have started doing this. For instance, in France, there is the CNC Fund, which is backed by the government.This fund offers grants to VR and AR companies, provided these companies partner with local talent in the development and production of VR content.The fund also has the mandate to provide tax rebates of up to 30% to foreign companies that produce VR content within the country.These forward-looking policies meant to support VR and AR development and production are a fairly new approach to encouraging people to get into the VR industry, and therefore we cannot say with absolute certainty whether the policies are effective.However, available evidence seems to support the view that the polici es are working to encourage people to get into the“traditional” film industry.For instance, following the implementation of such policies to support the traditional film industry in France, 31 projects were launched in France within a year, with the companies involved in these projects coming from eight different countries.These projects took over 450 days of filming and saw over €119 million spent within the country, which is a great improvement compared to 84 days of filming and just €7.4 million spent in the year before the policies were passed.Considering that the VR and AR industry is still in its infancy, it is still too early to say whether the gains seen in the traditional film industry will be replicated in the VR and AR industry.Considering the growing popularity of immersive content, however, we can expect these policies to have similar effects within the industry.Content Will Become More Personalized, But This Will Come at a CostToday, almost everything is becomi ng digital. In addition, the business models of most digital services are becoming more reliant on the gathering of personal data as a way of providing a more personalized experience to users.This need for personal data is giving software designers an incentive to do all they can to keep users engaged within their apps and websites for as long as possible.This is because the longer users remain on the apps and websites, the more data they generate.Developers are continually trying out tons of features with the aim of making their apps and websites as engaging as possible.Those with huge budgets are also working with teams of psychologists to find out what keeps people engaged and then implementing this within their apps and websites.As these digital services become more engaging, the more time we spend on them, which in turn means we generate more personal data.This data is then used to personalize the experience for us and make it more engaging, leading to a cycle that will see us spending more time on these services. As immersive technologies become more mainstream, we can expect that this cycle will become even faster.The result is that immersive content will become more personalized than most of the other forms of content we have today. This will have a number of effects, including:Advertising Will Become More TargetedToday, the personal data we have left behind during our interactions with digital services has allowed advertising to become highly targeted.Today, advertisers can target you based on things like your internet searches and your Facebook likes.As immersive technologies go mainstream, we will be providing more data to advertisers, which they will use to serve targeted advertising at unprecedented levels.Already, ads served through AR and VR devices have been shown to be 30 times more effective compared to ads served via mobile.As immersive content becomes more personalized, we can only expect the effectiveness of AR and VR ads to increase.Incre ased Engagement Might Have a Negative Impact on our Privacy and Well-BeingThis quest by developers to capture our attention will have two negative effects.First, it might end up being harmful to our well-being. Various studies have shown that people who spend more time on non-screen activities are more likely to report feeling happier.For instance, a longitudinal study of Facebook use found that increased engagement on the social platform led to decreased levels of individual well-being.Similarly, another study found that US teenagers who spend about 6-9 hours on social media per week are 47% more likely to feel unhappy compared to those who devote less time to social media.Secondly, enjoying an engaging and personalized experience on most digital services requires us to trade in our personal data.Unfortunately, once we give up this personal data, we have little say over how the data is used.Over time, this lack of control over our data will discourage users from adopting new techno logies over the long term.According to a report by the World Economic Forum which polled over 6000 people of different ages in 6 different countries, 47% of the participants reported that they have a avoided or stopped using a service because they felt that they had no control over their personal data and how it is used.In countries like China, this figure rises as high as 70%.This is a clear indicator that privacy and sovereignty of data is a major concern for users.Considering that immersive technologies provide enhanced data tracking capabilities (facial expressions, eye movement tracking, haptic data, etc.), therefore making our privacy more vulnerable, we can expect that these concerns about user privacy will become even more pertinent.STRATEGIES TO MAKE VR AND AR DESIGN AND DEVELOPMENT MORE USER-CENTEREDIf immersive technologies are to go mainstream and gain widespread adoption, developers and designers will need to address the concerns raised above. Below are some strategies and recommendations on how to make VR and AR design more user-centered:Regulatory frameworks: The same privacy concerns that have plagued other forms of digital media are also becoming apparent in VR and AR technologies. Considering that developers are not doing much to address these concerns, regulators will need to step in and come up with frameworks for protecting users.A great approach to developing a regulatory framework to protect user privacy in regards to immersive technologies is to borrow a leaf from regulatory frameworks that have been put in place to protect users of other forms of digital technology.For instance, many jurisdictions today have in place laws to prevent providers of digital services from collecting data without the consent of users and others requiring these companies to disclose how personal data will be used, or to erase personal data on the user’s request.The same approach needs to be applied in regards to immersive technologies.Give users sovereignty of personal data: Concern   over the collection of personal data by companies has led to the emergence of services that act as buffers between users and companies, giving users control over the data that they share with these companies, as well as anonymizing   some of this data.With traditional digital media, we have various such tools, including VPNs, privacy-focused browser extensions such as Privacy Badger, and entire browsers such as the Tor Browser.While such tools are currently lacking for the immersive environment, they will need to be developed in order to ease privacy concerns among users.Managing Consumption: Today, we have multiple solutions meant to prevent the overuse of most forms of digital media. For instance, we have services that allow parents to manage the kind of content their kids can access online, as well as other services that allow users to receive warnings once they exceed healthy levels of screen time.Similar solutions also need to be developed to manage and control the consumption of immersive content.While such solutions are not infallible, they will go a long way in managing the consumption of immersive content and complimenting regulatory frameworks.WRAPPING UPWhile VR and AR technologies are still in their infancy, we can expect that they will grow to gigantic proportions.Over the next decade, there is a chance that the VR and AR industry might grow to become bigger than the TV industry.These technologies will shift content consumption from observation to immersion, reduce the cost of production in creative activities, lower the barriers to entry and act as a tool for enhancing empathy and cognitive ability.However, for these immersive technologies to go mainstream, a number of challenges and concerns will need to be addressed.Governments will need to partner with creators to develop talent and provide incentives for more people to get into the industry.In addition, governments will need to step in and develop regulatory frame works, while developers and creators should also focus on efforts to address concerns over the privacy of users.

The Expansion Of Interest Groups - 747 Words

The emergence of interest groups in the European Union weakened the union’s overall power ; however, many politicians collaborate with them to gain an advantage. It is important to remember that interest groups are private firms, who can allocate their resources to provide studies for political actors. Interest groups provide â€Å"policymaking expertise, and implementation and monitoring capacity, the potential for a consolidated collective viewpoint, and the potential to enhance legitimacy â€Å"(Bache, Bulmer, George, Parker 2014, 310). With the acquired data, political actors can push forward stronger legislations built on concrete data. Interest groups pivotal role in the EU because they can use their resources to influence decision making in†¦show more content†¦Consequently, interest groups resemble a double –edged sword to the EU because although they can provide resources and information to public institutions, usually the largest groups will have t he most influence. Moreover, the amount of resources available â€Å"will secure ‘insider status’ with the policy makers or remain outside the policy process. (Bache ,Bulmer, George, Parker 2014, 315). The firms who control insider status will indirectly possess some control about the policies discussed in the EU. However, large firms also carry a substantial amount of influence because of their economic power. For example, politicians will find their hands tied if they decide to rule against one of the largest job suppliers in a country despite huge strikes against them. As the author states, â€Å"large firms find it easy to become privileged interlocutors of the political administrative system, thanks to their economic importance. â€Å" (Bache ,Bulmer, George, Parker 2014, 316). The wealth and resources possessed by large firms make interest group politics a process where the strongest stay on top and dominate conversations. Therefore, although in the last decade ’s interest groups have advocated for positive social, environmental, and economic changes, their role is contested against business interest. Clearly, interest groups’ in the EU is ultimately very circumstantial because they can advocate anything from same-sex marriages to fewer taxes on the rich.

A Brief Note On Unemployment And Its Effect On The Economy

Unemployment plays a huge factor in the appearance of a good economy. All over the world governments try to decrease the amount of people that are unemployed in its country. Governments always want to try and provide fixes to things such as unemployment by instituting minimum wage laws, job security laws, and setting regulations on working conditions. While most of these things may seem necessary and even beneficial we have learned that laws and regulations such as these set on businesses typically hurt the ones they are trying to help the most. It is another case of focusing on the goals that these policies have and not focusing on how well they work and not how well they work out for the group of people that these policies are put in place to help. We have already learned about how things such as price controls can be bad for the economy and it is no different applying it to the agricultural industry or the labor force. One of the most talked about aspects in the United States to help unemployment and help people make more money is by raising the minimum wage. A minimum wage is a law set in place by the government that tells businesses that they cannot pay below a certain amount. The first minimum wage law in the United States was passed in 1938 by Franklin Roosevelt. There has recently been a lot of talk about raising the minimum wage to a living wage. The problem with minimum wage laws is that when a price is artificially raised it tends to cause more to be suppliedShow MoreRelatedA New Up And Coming Uk Government1674 Words   |  7 Pagesrise in unemployment and the lengthy period of recession.

Economic immigrants come primarily from Europe, Asia and, most recently, Latin America.Read MoreRelationship Between Unemployment And Inflation3391 Words   |  14 Pages[TYPE THE COMPANY NAME] Economics Assignment [Type the document subtitle] 1/18/2015 â€Æ' Table of Contents: Table of Contents: 2 Section 1: Relationship between Unemployment and Inflation 3 Unemployment: 3 Inflation: 3 Phillips curve: 4 SRPC- Short Run Phillips curve: 4 Real Life example of Unemployment in Australia 5 Section 2: Simple model of AD and AS 6 Aggregate demand and Aggregate supply: 6 What is AD or aggregate demand? 6 Consumption Expenditure: 6 Investment Demand: 7 Government Expenditure:

Ah, Woe Is Me Free Essays

In the beginning of this short story we are introduced to Sarah, an aging black servant living in South Africa. She works hard for an upper-class white family and spends all of her money on education for her three children who are sent to a boarding school. They come home once a year at Christmas, and the first time the narrator meets the children, she is surprised at their well-mannered behaviour. We will write a custom essay sample on Ah, Woe Is Me or any similar topic only for you Order Now She finds, however, that Sarah is a bit harsh towards them, and she comments on this. Sarah tells her that it is better to learn the lesson now and grow to accept ones fate later. In the course of the following year, Sarah must give up her job because of her legs, and one day her daughter comes to the house. Slowly she tells her story to the narrator. How the younger brother is working now, and how she is taking care of Sarah. The narrator offers her some clothes and some money and invites her inside for a cup of tea. When she is about to leave, she starts crying and can only mutter that her mother is very ill. Unsure of what to do, the narrator hands her a handkerchief. The setting in this story is South Africa in the 1950s. Apartheid and segregation are words that describe the conditions under which the blacks (the native Africans) live perfectly. The blacks nearly have no rights and must accept being oppressed by the whites. Sarah is only one of many poor blacks who only just manages to earn a living by working as a servant for a rich white family (the narrator). Slavery does not exist anymore, but it can be difficult to distuingish the life of a slave from that of a native African in the 50s except from the fact that they do after all get paid for their work. Sarah is very concerned about her children getting a good education. She probably wants them to have a better life than she has had so far, and while that is a very noble thought, the facts speak against it. Her children do not at this time have a very good (if any) chance of getting a good solid education because it is very expensive, and their mother does not make that much money. Even if she did make enough money, her legs are bad, and at the end of the story, she has to give up her job (and thus take her children out of the boarding school) because she cannot afford to pay for the school. This is what could look like the final blow to her childrens future success in life. No education means no chances of getting a better life in South Africa (and just about everywhere else, too). But what if she did have enough money to give her children a proper education – would that guarantee the children a good future life I gravely doubt it. As I said before, the blacks live almost like slaves, and as such, they do not have the opportunity to climb the social ladder. All in all, Sarahs hopes and dreams for her children are all very noble, but, unfortunately, at that time and place, very unrealistic. The narrator does not treat Sarah any better than most other white people in South Africa at this time. While she allows Sarahs children to stay in her house during Christmas, I think the only reason she does it is because she tries to escape her own bad conscience. It is Christmas after all. Throughout the rest of the year, she does not even think about helping Sarahs children financially so they can stay in school. Even though she presumably has more money than Sarah will ever see, the thought of helping her servant out does not strike her at any point in the story. Her servant is her servant, and servants children are not someone she thinks about. This point is also very clear to see when one reads the description of the narrators thoughts about Sarahs children. She is surprised at how well they behave, how good their manners are; as if she was expecting a horde of wild animals instead of normal human beings. She is undoubtedly not the only one to think this way about the blacks, they were considered animals by many white people at that time. However, the narrator seems to excuse her treatment and behaviour towards Sarah and her family with ignorance (see lines 99-103). I find it hard to believe that this ignorance really existed, but it is possible that it did, because the whites and the blacks were so distinctly segregated by the apartheid system. Yet I find it hard to believe that the narrator was completely unaware of Sarahs almost inhuman standard of living. Surely, even though apartheid almost divided the whites and the blacks into two separate worlds, she must have known something about the conditions under which Sarah and her children lived, and that it was getting worse as the days went by (because of the mothers bad legs). When Janet, one of Sarahs two daughters, comes to visit the narrator in the end of the story, the narrator once again displays her ignorance about the blacks, but this time she openly admits it. Janet is, of course, in an unpleasant situation when she stands in the back yard of her mothers former employer. Everyone has some pride in themselves, and standing in the back yard, asking for alms is, of course, very degrading to a proud person, no matter who that person is. Janet has probably tried being in a similar situation before, but now that her mother is unable to provide for the disintegrating family (her father has lost his job and her sister has married and moved away), the life and death of her family depends solely on her and her brother who are the only ones working. Janet is of course very depressed and sad, but she cannot give up now. Her last hope is that the narrator will help her out, and, fortunately, she does. The handkerchief is actually the first thing the narrator has ever done to help Sarahs children. It is not until that point in the story Janet realizes just how bad things are with Sarah and her family. Of course, one could again be tempted to think that it was only her bad conscience that made her give Janet the clothes, but there is no way to be sure. I am, however, inclined to believe that the narrator has finally realized how immense the difference between the â€Å"black world† and the â€Å"white world† really is. However, the things she gives Janet (some money and the handkerchief) will not last long, and what will Janet do then Come back for more, of course. I am not saying that the narrator is doing something bad, but I do not think she realizes that Janet will probably come back again. It is like giving a stray cat some food; it will always come back for more. The question is if the narrator would give Janet more money if she came back, and if it would be any help at all. The first question is easy: Yes, she would give her more money if she came back – her conscience forbids her to do otherwise. The second question is a bit more difficult to answer. Of course the money is an instant help to Janet and her family, but only a very insufficient one. The few dollars (or whatever currency they use in South Africa) she gives Janet will only provide the family with a meal or two, and after that they will be back to where they started, and would have to beg for more money. Now, I am not saying charity does not help, but I do not think it helps as much as many people would like to think it does. In many cases, it only puts off the sufferings. The apartheid system has officially been abolished in South Africa today, but I think old habits die hard, so to speak. I am sure there are still blacks like Sarah and her family who have to subordinate to the richer white population even though – officially – apartheid does not exist there anymore. Societies do not change overnight, especially not when one group has to give up its right and privileges and share them with others (whom they dislike). Sarahs story is undoubtedly not the worst example one could find, but no one knows what happened after the scene in the narrators back yard. How to cite Ah, Woe Is Me, Essay examples

Nanotechnology Immortality Or Total Annihilation Essay Example For Students

Nanotechnology: Immortality Or Total Annihilation? Essay Technology has evolved from ideals once seen as unbelievable to common everyday instruments. Computers that used to occupy an entire room are now the size of notebooks. The human race has always pushed for technological advances working at the most efficient level, perhaps, the molecular level. The developments and progress in artificial intelligence and molecular technology have spawned a new form of technology; Nanotechnology. Nanotechnology could give the human race eternal life, or it could cause total annihilation. The idea of nanotech was conceived by a man named K. Eric Drexler (Stix 94), which he defines as Technology based on the manipulation of individual atoms and molecules to build structures to complex atomic specifications (Drexler, Engines 288). The technology which Drexler speaks of will be undoubtedly small, in fact, nano- structures will only measure 100 nanometers, or a billionth of a meter (Stix 94). Being as small as they are, nanostructures require fine particles that can only be seen with the STM, or Scanning Tunneling Microscope (Dowie 4). Moreover the STM allows the scientists to not only see things at the molecular level, but it can pick up and move atoms as well (Port 128). Unfortunately the one device that is giving nanoscientists something to work with is also one of the many obstacles restricting the development of nanotech. The STM has been regarded as too big to ever produce nanotech structures (Port 128). Other scientists have stated that the manipulation of atoms, which nanotech relies on, ignores atomic reality. Atoms simply dont fit together in ways which nanotech intends to use them (Garfinkel 105). The problems plaguing the progress of nanotech has raised many questions among the scientific community concerning its validity. The moving of atoms, the gathering of information, the restrictions of the STM, all restrict nanotech progress. And until these questions a re answered, nanotech is regarded as silly (Stix 98). But the nanotech optimists are still out there. They contend that the progress made by a team at IBM who was able to write letters and draw pictures atom by atom actually began the birth of nanotech (Darling 49). These same people answer the scientific questions by replying that a breakthrough is not needed, rather the science gained must be applied (DuCharme 33). In fact, Drexler argues that the machines exist, trends are simply working on building better ones (Unbounding 24). Drexler continues by stating that the machines he spoke about in Engines of Creation published in 1986 should be developed early in the 21st century (Unbounding 116). However many scientists still argue that because nanotech has produced absolutely nothing physical, it should be regarded as science fiction (Garfinkel 111). Secondly, nano-doubters rely on scientific fact to condemn nanotech. For example it is argued that we are very far away from ever seeing nanotech due to the fact that when atoms get warm they have a tendency to bounce around. As a result the bouncing atoms collide with other materials and mess up the entire structure (Davidson A1). Taken in hand with the movement of electron charges, many regard nanotech as impossible (Garfinkel 106). But this is not the entirety of the obstacles confining nanotech development. One major set-back is the fact that the nanostructures are too small to reflect light in a visible way, making them practically invisible (Garfinkel 104). Nevertheless, Nanotech engineers remain hopeful and argue that; With adequate funding, researchers will soon be able to custom build simple molecules that can store and process information and manipulate or fabricate other molecules, including more of themselves. This may occur before the turn of the century.(Roland 30) There are other developments also, that are pushing nanotech in the right direction for as Lipkin pointed out recent developments have lead to possibilities of computers thinking in 3-D (5). Which is a big step towards the processing of information that nanotech requires. Although there are still unanswered questions from some of the scientific community, researchers believe that they are moving forward and will one day be able to produce nanomachines. One such machine is regarded as a replicator. A replicator, as its name implies, will replicate; much like the way in which genes are able to replicate themselves (Drexler, Engines 23). It is also believed that once a replicator has made a copy of itself, it will also be able to arrange atoms to build entirely new materials and structures (Dowie 5). Ethnographic Paper EssayOne scenario which illustrates the danger of nanotech is referred to as the gray goo problem. Gray Goo is referred to as when billions of nanites band together and eat everything they come into contact with (Davidson A1). However, Davidson only gets the tip of the iceberg when it comes to the deadliness of gray goo. Roland better illustrates this hazards threat; Nanotechnology could spawn a new form of life that would overwhelm all other life on earth, replacing it with a swarm of nanomachines. This is sometimes called the gray goo scenario. It could take the form of a new disease organism, which might wipe out whole species, including Homo Sapiens(32). Simply put the nanites would replicate to quickly and destroy everything including the human race (Stix 95). Moreover, the rapid replication rate that nanotech is capable of could allow it to out-produce real organisms and turn the biosphere to dust (Drexler, Engines 172). However, death is only one of the da ngers of gray goo. If controlled by the wrong people, nanites could be used to alter or destroy those persons enemies (Roland 32). But gray goo is only of one of the many potential harms of nanotech. If so desired, nanotech could be used as a deadly weapon. Although microscopic robots dont sound like a very effective weapon, Drexler states that they are more potent than Nuclear weapons, and much easier to obtain (Engines 174). But aside from being used as a weapon, nanites would be able to produce weapons at a quick and inexpensive rate. In fact, with the ability to separate isotopes and atoms one would be able to extract fissionable Uranium 235 or Plutonium 239. With these elements, a person has the key ingredients for a nuclear bomb (Roland 34). As a result of the lethality of nano-weapons the first to develop nanotech could use it to destroy his rivals. New methods for domination will exist that is greater than Nukes and more dangerous (Roland 33). This along with simple errors, such as receiving the wrong instructions points toward nanotech doing more harm than good (Darling 56). Moreover, the threats from nanotech could be a potential cause of extinction (Drexler, Engines 174). Drexler continues by saying that unless precautions are taken nano could lead to complete annihilation (Engines 23). However, if nanotech does not lead to extinction, it could be used to increase the power of states and individuals. Bacon believes that only the very most elite individuals will receive benefits from nanotech. Beyond that however, it is perceived that advanced tech extends the possibilities of torture used by a state (Drexler, Engines 176). However, states will become more powerful in other ways. With the increase means of production, nanotech could remove the need for any if not all people (Drexler, Engines 176). This opens new doors for totalitarian states. They would no longer require keeping anyone alive, individuals would not be enslaved, rather they would be killed (Drexler, Engines 176). It is perceived that all the benefits would remove all interdependence, and destroy the quality of life itself (Roland 34). In the end, nanotech could give a lifestyle never before imagined. On the other hand, it could destroy entire species. The effects and potentials of nanotech are best sum med up by its inventor, Drexler, Nanotechnology and artificial intelligence could bring the ultimate tools of destruction, but they are not inherently destructive. With care, we can use them to build the ultimate tools of peace (Engines 190). The question of how beneficial nanotech will prove to be, can only be answered by time. Time will tell whether developments and progress in artificial intelligence and molecular technology will eventually produce true nanotechnology. And, if produced, whether this branch of science will give us immortality or total annihilation.
