Help me, please~~~ i have no idea d: do you think computers help society? do you think computers are bad for health? how do you think computers have changed the world?

As we live in the 21st century, we must accept the inevitability of a computer revolution. Computers help society, due to their using we can do many things as follows: internet connection helps people from all around the world know each other. Distance learning, for example, gives disabled people a possibility to study and communicate. People can have an opportunity to work at home using only a computer. In general, computers have made things simpler and more effective.
At the same time, as proverb says “two sides of the same coin”, some people hold an opinion that computers have a negative impact on people`s health. People who are against computers say that computerization is bad for society. Communication via computers can`t replace a vivid conversation or meeting. Parents pay attention that there are so many negative information their children receive using the Internet, as well as the popularity of computer games is bad for children`s health and behavior.
To my mind, computers have changed the world. We can`t deny this tendency but we should be attentive using computers and not to forget about real world.
