If by valuable you mean they keep you employed despite not doing anything, sure. They are valuable for career progress and such, but when faced with real technical difficulties, you are not going to talk yourself out of it. Or maybe you can, delegate them to some poor bastard. What a wonderful world we are living in.
I didn't say that I did nothing, I just know that I have been more productive in previous jobs due to a number of factors. But hey perhaps you lack some social skills jumping to conclusions like that.
