We have changed a lot from the age of the Renaissance, where the ideal for each person was to be able to do a great many things well. We are entering the age of specialization. Increasingly people are training for more and more specific jobs and well they should be. With the vast amount of information available on so many subjects, it would be nearly impossible for one person to be expert in more than a few areas.
