I mostly agree. My DNS mentor, whose job was basically a DNS industry expert, was fired without cause one day, and it always left a bad taste in my mouth. That said, while I've always considered myself a generalist, being the 'DNS guy' has proven invaluable in my experience. People treat you like some kind of wizard. I guess I've come to the conclusion that it's likely best to be a generalist with a few really deep specialist qualities.
