No one can get away with this any more and that is a great thing. It is also a great thing to be able to check your facts before you state them. You no longer have to rely on a book you read in 1977.
Far from making people less intelligent this ability makes them much MORE intelligent. If you have to look something up 3 or 4 times, chances are you'll remember it the 5th time.
