Is the nature of employment changing?

I found this article on my favorite liberal (progressive?) Web site saying that office workers at all levels are gradually being replaced by computers in the same way that manufacturing jobs have been replaced by machines. http://tinyurl.com/yko5y3u Do you think that this is the case? Might the difficulties in making the transition account for some of the current high unemployment?

It is kind of a strange world being described by the article, with most manufacturing related work being done by machines and people doing a lot of health related work. It reminds me of the Time Machine where the people played all day and the Morlocks (who could be thought of as representing the technologists) manipulating them.
