About forty yeas ago, when ATMs first started to appear, a banker told me that tellers would no longer be needed. When I protested that I preferred a teller, he told me that young people would all go to ATMs and us older characters would eventually disappear. Well, as you know, there are now more tellers than ever because banks have entered retail stores and now have long hours(banker's hours is no longer a joke). My wife is a librarian and was told long ago that librarians would not be needed because of the information available on the Internet. Well, librarians are now "information specialists" and are needed more than ever to guide people through all the misinformation on the Web.

On the other hand, the computer compelled many men to learn how to type who otherwise would have left that to the female secretary. The typewriter is gone, but typing is here to stay.
