With the rapid advancement of communication technology: smart phones, tablets and other mobile devices, some people believe that the disadvantages outweigh the advantages. To what extent do you agree or disagree?

Over the past decades, there has been a growing trend towards the quickening rapidity of technological communication from smartphones, tablets to other mobile devices in both developed and developing nations. It has affected relationships in various ways, and in my opinion there are both positive and negative effects.

There are a number of reasons why these developments bring several advantages. Firstly, t is undeniable that telephone and internet revolutionize the way we communicate in business, education and social life. Thanks to them, business people all over the world are able to interact without ever meeting each other. Secondly, services like Skype create new possibilities for relationships between students and teachers. A student can now take video lessons with a teacher in a different city or country. Or channels online like Youtube bring a great deal of free English knowledge and extremely essential for student that is studying English or want to improve it without needing in order to enroll in English language centers.

However, many argued that the substantial development of technological devices in this field do more harm than good. Particularly, the availability of new communication technologies can have the result of isolating people and discouraging real interaction. For example, many young people tend to use popular apps like Facebook, instagram in order to make a new friends and chat online rather than mixing with their peers in the real world, and these "virtual" relationships are a poor substitute for real friendships.

In conclusion, although some experts imply that this trend cause drawbacks society, it seems to me that advantages still outweigh the disadvantages.
