Internet dating is becoming more and more popular. However, many people say that meeting people online is dangerous.

Nowadays a lot of young people feel that meeting people online is just the same as meeting in a bar. Many of them make friends online and even fall in love with their virtual interlocutors.
To my mind, it is silly to trust a person you have never seen. You can never be sure that you communicate with the individual whose personal information and photos you see. For example, a "young" boy may turn out to be a 50-year-old man. Besides, it is very dangerous to give detailed personal information to complete strangers. Your online friend may be a swindler or even a murderer. So meeting such a person in real life may be extremely risky.
On the other hand, some people say that internet dating has many advantages. Firstly, it is easier for shy people to chat through a keyboard than face to face. Secondly, you can search the Internet when you are not busy. Besides, you can talk to lots of people at the same time and you can have several online boyfriends or girlfriends. One can list all his or her romantic requirements and then find exactly what he or she wants. But I still believe that face-to-face dating is much better.

To sum up, internet dating may help you find love. If you don't meet someone in real life, it seems a great alternative. But Internet daters must be cautious because you never know what you are going to get from online romance.

 

Artificial intelligence performs quite a lot of jobs nowadays. However, many people are worried about computers doing the same things that people can do.
In the 90s and early 21st century artificial intelligence achieved its greatest success. Today clever machines are taught to think and make decisions. But is it safe that artificial intelligence is invading the world?

To my mind, computers and robots are very helpful. There are more and more jobs which humans leave to robots such as exploring another planet, defusing bombs or just doing boring household chores like cleaning. Computers can perform a lot of functions: they can control cars and planes, give us the news or compose music. Many factory jobs are performed by industrial robots nowadays. It has led to cheaper production of various goods, including automobiles and electronics. Artificial intelligence has successfully been used in a wide range of fields including medical diagnosis, stock trading, robot control, law, scientific discovery and toys.

However, there are some reasons to worry about robots. Firstly, the use of robots in industry leads to unemployment as many jobs are performed by machines. Secondly, industrial robots can be dangerous and cause harm to human workers. Besides, many people fear that highly intelligent robots may take over and destroy the human race. There are a lot of books and films about people losing control over clever machines that begin to kill their creators. But I believe that it is early to worry because robots are still clumsy and not very intelligent.
To conclude, artificial intelligence serves to help people and make their lives easier. That is why I think that we should promote research in artificial intelligence. But people must be careful and pay more attention to security.



 

People have different attitude to cloning. Some of them think that cloning opens new possibilities, while others are convinced that it is morally unacceptable.
Scientists have always dreamed of reproducing exact copies of animals and even human beings. They have already succeeded in this field and created Dolly, the first cloned sheep, and many other animals. But the question of cloning, especially human one, still remains controversial.
Personally, I think that cloning plants and animals is rather interesting and exciting. Cloned animals may be strong and healthy and they may produce more wool, meat or milk. Besides, cloning will help us preserve species that are on the brink of extinction. Moreover, cloning gives people new medical possibilities. Owing to it, scientists can create organs for transplantation and save people who need a new heart, liver or kidneys.
However, quite a lot of people are against cloning. They say that people must not interfere in the process of creating a new life because it is the duty of nature. What is more, scientists don't know for sure how clones will behave and what diseases they may transmit. As for human cloning, it seems to be dangerous and morally unacceptable.
To conclude, I think that science must develop in order to improve our lives. But people should be more careful when they use new technologies and investigate new phenomena. So to my mind, cloning must be used only when it is necessary to save lives and to solve important problems.
