That is an interesting thought. So exactly what sort of old stuff are you talking about? In most cases on the dev side I don't encourage people to learn C++, I would point them more toward .net C#. It is sort of interesting on the db side because people can be so isolated in what they do. For instance a DB admin, knows how to setup / install sql server. Get backups going etc. Still, their t-sql skill may be terrible. Anyway, let me know what sort of old stuff you think people should be learning, try to be more specific.
Thanks for your comment.

I think he is mostly referring to the fact people are quick to jump on something new rather than take the time to fully lean what they have.
