In the modern world,it is possible to shop,work and communicate with people via the Internet and live without any face-to-face contact with others. Is this a positive or negative development?

The Internet is now considered more handy than any traditional form of communication along with shopping or offline work. While some claim that a shift occurring in the lifetime of individuals brings more inevitable assets, the others, including me, spark controversy.

There is an indispensable fact to acknowledge in terms of the nature of the Internet which is regarding the convenience. Telecommuting,for example, eliminates the need to travel from home to work, being stuck in the traffic congestion and a majority of people are found exposed to barking people with zero patience as well as bunking cars which can torture mentally, leaving work at home as more appropriate choice to be down. The availability and the larger scope of choices of the materials or products in offer concerning shopping are another advantage which enables every purchaser to look through items and come to final decision out of many which a physical shop can not cater.

However, these might be flawed by a set of assertions which compel some to contend about the possibility of privileges of face-to-face interaction . Firstly, once it is stated about the online community, it can be seen as a home of violence and share of misinformation which can target the young mindsets whose privacy has a higher tendency to be invaded. Unreliable contacts or potential of turning them into the street of crime or nudity are the clear consequences of the Internet. Secondly, while shopping, it is more proper to browse through and try on clothes which one is about to purchase so as to check the quality and real size or trade bargains rather than being hunted by online frauds who pretend to be a retailer until enriching their account at the bank with your money.

To sum up, although a range of people have preferences for online means of shopping or working on the account of more variability and less time to waste on trips on the road, the rest of them insist that albeit the inconvenience, physical forms of communication and shopping offer more benefits to users like more reliability together with financial safety.
