A lot of old guys(40 is old eh!) I meet are into managerial/advisory roles and even though they wont know the underlying details of the framework it does not take them much time to understand it, because there is always something similar they had during their time. The time I spent mastering, adobe flex, javas struts framework, GWT and the likes. Could seem like wasted time. But in the larger scheme of things it just made me smarter. I know what worked for them and what didn't and that helps me understand the future frameworks better.
