Careers and Career Areas Change Quickly

There are many, many, many careers that are so-called "hot" careers that didn't exist even 5 or 10 years ago. Now we have an entire industry sector that didn't exist until a few months ago. It is called "service science", according to the Service Research and Innovation Initiative. The career area is a combination of computer, management, and social science. The aim of having this as a regular unit of career training is to improve the productivity of serving people. According to Steve Lohr of the NYT, these jobs account for 80% of the economy.
When I look at the components in this career area--it looks rather disharmonious---social science study is usually pursued by those who have a social component to their personality--that sounds good so far--because if you are a customer service rep then you have to be a social animal.....but when I examine the other components--computers--more Realistic/Investigative, management--more Enterprising--it doesn't seem to "compute"--haha, sorry for the pun....
But then again, nothing to seems to "compute" in the career market today--who would have thought 20 years ago that the manufacturing sector in the American economy would be TOTALLY gone! who would have thought that the traditional banking jobs would be kaput!!!
We have a lesson to learn from all of this--anything is possible if it involves Technology
