Libraries vs. Modern Technology

I recently took a trip to New York with my oldest son who's in his 20's. We drove to Brooklyn to get my 6 year old grandson from his summer visit. During the course of our 1000 mile road trip we got to talk about a lot of interesting things. One of the topics to come up libraries and modern technology. Well, my son, believes that because of the internet and it "partners"(google, wicked-pedia,etc), that soon libraries will be simply literary museums. I tried with no luck to point out that contrary to what we might believe about the internet, it is not quite as reliable as the "hype" suggests.
Well quite by accident my point was proven with a simple instrument of modern technology called a "GPS enabled cell-phone". My son decided he would demonstrate how effective/reliable modern technology is. He entered an address for our destination in Brooklyn and waited for the GPS to give directions to avoid the afternoon Washington,DC traffic. We waited... and waited... venturing farther into jams. Ignoring signs and good sense, I decided to allow my son's "toy" to lead us where it would. Well, about 30 miles off course my son happened to notice a small message
"GPS Failed". From that point he had no problem following the "primitive" signs.
