One of the great things about my boss is that he talks frankly about the fact that many of us will move on and actually gives advice on what to try in your career "someday". This isn't because we express, or have much reason to express, dissatisfaction. It's simply pragmatic. Highly skilled workers have options and often ambition and curiosity too. Searching for " software job tenure" seems to indicate that most go through many companies in a career. Sometimes a company really does fail it's employees, but sometimes it really is just a chance to try something new. The point being, the author is speaking in too general terms. It's probably ok, even necessary, to not be everything to every employee.
