According to Nicholas Carr, author of the article Is Google Making Us Stupid? it seems so.
Now, I do not have much to go on personally, however, I do not disagree with it. It seems that since Google, most people would rather take the easy way out of doing everything. What is this? What is that? What does this? How do you do this? The answer is always the same, check Google. Google has become a scapegoat for the lazy. It has made even the hardest workers lazy. People would much rather get a summary of something instead of read the actual book. There is no one who is innocent of this, myself included. It is easier. However, this is not an accurate synopsis of everything that is in the book. If you want the entire content, you have to do the work. Read the book, do the paper, finish the article. It is not as easy as looking up work from someone else and attempting to copy it for yourself.
Google has also been a Godsend. It has helped those who need the extra push. It has helped writers come from writers block. It can help you find the book you need for the paper you are doing. It has multitudes of PDFs and online books at your finger tips. Many people use these for research and sometimes pleasure reading. Google has been an engine that is heaven and hell mixed into one huge database.
It has also been easier to get data and different things out to others. You are able to send a PDF of your paper or novel to a friend for editing. Before now, it was something you had to print and send off for weeks at a time. Now you can find editors online instead of having to drive states over to drop a copy off in person just to be rejected. The bounce back time is cut at least in half.
I do not think that Google is making us stupid. I believe that Google is making us lazy. Our generations do not have the attention span that we once did. Google is making it easier for instant entertainment.
