should you enter a dispute with somebody about the validity of a certain fact , it is not necessary to search for the solution in giant paper encyclopedias , for google is indeed a much faster way ; it is not necessary to meet with friends in person in order to find out how they are and what they were doing over the weekend , it could be easily learnt from visiting their facebook , instagram or twitter pages ; it is not necessary to wait for news bulletins on tv and devour information that channel editors choose to feed you , the internet could provide the whole spectrum of events in just one click ; personal presence in auditorium is no longer really necessary in order to study , almost any recourse could be found on the world wide web ; there is no longer any need to go to the library to find and read a book , because it is way more convenient to get an electronic version of that book , which you can instantly start reading no matter where you are .
