Whilst going through this month's Computer World Magazine, I found this interesting article. They have done a study and have come-up with a list of dead or dying IT Skills that were considered very important at one time. The list is given below.
Non relational DBMS
Certified Netware Engineers
PC Network Administrators
The key message is, if someone is working hard now on one of these technologies, it's worthwhile to question whether it's the right investment.
I am not surprised at this list. However, I was under the impression that C Programming is still popular in some domains like Reserach/Science. I didn't think that PowerBuilder, Netware Engineers and PC Network administrators are getting obsolete as well.
It's amazing how fast things change in this industry. Some of these technologies have had a very high demand at one time but today no one wants them. This is a good eye opener to everyone who is involved in IT because if we don't up-skill ourselves and learn new things, we are going to be redundant in the near future.
The link to the full article is given below and I suggest reading it if you are doing something related to IT. It really shows how the IT landscape changes overtime.
