In my humble opinion I suspect that the only fields more arrogant then the computer field are law and health fields. Then of course you can throw in the engineering and political fields. Have I missed anyone.
I seem to be cut from the old hacker mentality that all information should be shared and the collective minds can improve it to perfection. I have increasingly found though a mentality of "ask me no questions and I'll tell you no lies".
I guess my being a narcissist isn't what it used to be.
