Internet is very important for online programs. If some day don't have internet, social onlines will become on.
Nowadays, in my oppinions most people addict smart phone all the time. I think it is not bad because When you are not home, you can not use computer for work but you can use your smart phone. It is convenient for do everthings easier.
For example, when you are far form your family or friends, you can use internet on many applications such as the Skype, Line, Facetime, etc for communities.
