Specializing is a very good idea ... for some people. It does however have it's down sides. One of those is that you can end up quite restricted geographically. Ie, you specialize in industry A or technology B and want to live in city X or country Y and unfortunately those options are not compatible. People optimize for different things and I've deliberately stayed a generalist to enable me to move to wherever I want to live and have no problems finding employment.
