THE ADVANTAGES AND DISADVANTAGES OF TECHNOLOGY

First, we are going to tell about the advantages of technology. Now we all know that technology has really changed our lives. There are lots of improvements we are now using because of technology.

Communication

Our means of communication has greatly improved in the dawn of the modern technology. We now have so many hi-tech gadgets that we use for everyday communicating with people from all over the world. The telephone is a very helpful mean tool for us to talk with people from remote places, then came out the cellular phones, which we can take with us wherever we go. Now, we are given the privilege to use computers and the internet that has such a wide variety of easy communication offers. It is one of the reasons why we should be thankful for technology.

The disadvantage of this is that too many people can communicate with us all at the same time. It can create scams and spamming in a lot of ways. The youth has also been very much addicted to gadgets that they get to spend too much time with it.

Health

There have been lots of advantages with technology when it comes to health. Our lives will never be the same again after the breakthroughs of many medicines and other discoveries. Lengthening our lives is very easy these days. We can choose whether we want to live a longer life, and there are certain methods for that.

Production

The production has also been increased. Now, we can create materials in just minutes with multiple productions at a time. This is what the modern machines contribute to our society.

A disadvantage of this is the energy that it uses. It consumes a lot of energy to run the machines. And so, we need more fuel, and it will then leave a lot of waste and pollution to our environment. It is the most destructive price for our today’s technology.

Our ways of living has also been improved potentially. But still, there have been a lot of people who lost their jobs because man power has been replaced by machines. Also, if one wants to work with modern equipments, he cannot start work at hand because he has to undergo extreme training. It can be a disadvantage for people who wants to start the job soon so that they can get the payment.

We cannot avid these disadvantages that goes along with the advantages of technology. There are so many improvements we are having now, but still, we need to comply with what they cost in return. It is all part of the gambling we do with the environment for the sake of living an easier life.

Task 5. Discuss with a partner. Do modern technologies violate human privacy? Why?

Task 6. Read the article and answer the questions.

1. How does face-recognition technology work?
2. What did the researchers do in their first experiment?
3. How many students were identified in the second test?
4. What was the result from a third experiment?

ANONYMOUS NO MORE

You can’t hide—from anybody

If your face and name are anywhere on the web, you may be recognised whenever you walk the streets —not just by cops but by any geek with a computer. That seems to be the conclusion from some new research on the limits of privacy.   For suspected miscreants, and people chasing them, face-recognition technology is old hat. Brazil, preparing for the soccer World Cup in 2014, is already trying out pairs of glasses with mini-cameras attached; policemen wearing them could snap images of faces, easy to compare with databases of criminals. More authoritarian states love such methods: photos are taken at checkpoints, and images checked against recent participants in protests.

But could such technology soon be used by anyone at all, to identify random passers-by and unearth personal details about them? A study which is to be unveiled on August 4th at Black Hat, a security conference in Las Vegas, suggests that day is close. Its authors, Alessandro Acquisti, Ralph Gross and Fred Stutzman, all at America’s Carnegie Mellon University, ran several experiments that show how three converging technologies are undermining privacy. One is face-recognition software itself, which has improved a lot. The researchers also used “cloud computing” services, which provide lots of cheap processing power. And they went to social networks like Facebook and LinkedIn, where most users post real names and photos of themselves.

In their first experiment, the researchers collected images from 5,000 profiles of people on a popular American dating site in a particular city—most of whom used pseudonyms. They fed the pictures into an off-the-shelf face-recognition programme that compared them with 280,000 images they had found by using a search engine to identify Facebook profiles from the same city. They discovered the identity of just over a tenth of the folk from the dating site.

That might not seem a big percentage, but the hit rate will get better as face-recognition software improves and more snaps are uploaded. The researchers did a second experiment: they took webcam photos of 93 students on Carnegie Mellon’s campus, with their assent. These were fed into the face-recognition software along with 250,000 photos gleaned from publicly available profiles on Facebook. About a third of students in the test were identified.

But the most striking result was from a third experiment. By mining public sources, including Facebook profiles and government databases, the researchers could identify at least one personal interest of each student and, in a few cases, the first five digits of a social security number. All this helps to explain concerns over the use of face-recognition software by the likes of Google and Facebook, which have been acquiring firms that specialise in that technology, or licensing software from them. Privacy officials in Europe have said they will scrutinise Facebook’s use of face-recognition software to help people “tag”, or identify, friends in photos they upload. And privacy campaigners in America have made a formal complaint to regulators.

Given the sensitivity, Google decided not to release a face-recognition search engine it had made. Eric Schmidt, the executive chairman, has said it took the decision because “people could use this stuff in a very, very bad way, as well as a good way.” But face-recognition methods may still spread. As Mr Acquisti says, sharing named photos online has “opened the floodgates” to a new, privacy-sapping world. Shutting them will be hard.

Task 7. Answer the questions.

1. Do you use social media? If “Yes” – how often?
2. Why do people use social networking sites?

Task 8. Role play the following situations.

Activity 1: Your grandfather and uncle, who run a crop farm in North Dakota, are continually arguing about whether or not to incorporate various technologies into their work. Your grandfather generally believes that technology is destroying the farming industry, while your uncle thinks that embracing technology is the only way that their farm will survive and prosper. They want you to give an impartial view of the positive and negative impacts of various technologies (e.g., using global positioning and geographic information systems, biotechnologies) so that they can make informed decisions.

Activity 2: In your recent travels you ran across a remote farming community that has been cut off from the rest of the world for generations. You are a farmer from Iowa who has been incorporating various advanced and emerging technologies into your work. Based on your understanding of the positive and negative impacts of these technologies, what types of technology would you choose to introduce to this remote community? On what did you base your decision?
