That's worthless, believe me I know. If they raise the age 4 more years than I'll enlist with you. With any luck we'll invade India and China and we can shoot the sunavabitches who replaced us. :-P
I haven't been replaced (yet). Although most of my experience is in smaller companies where one has to have a broader base of knowledge to be successful, as opposed to larger companies where depth of knowledge is more important, but also makes you more replaceable (although I'm under no illusions that I'm somehow immune to being outsourced).
The downside is I don't have the management opportunities a larger company would have because I typically run a very small shop augmented by occassional third-party assistance.
