This is interesting, because I see some of myself in this. In my group of six, I'm the strongest technically, and my boss is probably stronger than only the new guy. Of the maybe fifteen others in the company who do similar work, only two come to mind as similar (probably better).
It's interesting to think what direction the company would go without me. There's work we need to do that I'm doing, but an incompetent organization could pretend they didn't know, not do it, and hope they don't get caught.
So if they had to cut a position, would it be my worthless boss (my choice), the least experienced, or me at one of the higher paid and also pain in the ass because I keep identifying issues we need to address?
