"Trevor, you are not a cynic, you are an arrogant SOB. Period. If you were able to just get over yourself a little bit, you'd find the rest of the world a much nicer place."
Like all people, I have my predjudices. I also - like all people - have many flaws. Unlike most, I spend a reasonable amount of time in introspection, and am aware of my predjudices and my flaws in great detail. Awareness isn't the ability to change, however - if it were diet failure, alcoholism and many other human psychological ailments wouldn't be an issue - but awareness is the first step.
Part of knowing thyself is knowing not only your faults and limits, but your capabilities and areas of knowledge/expertise/etc. I know what I know, and - far more critically - I know what I don't know. This has a few side effects.
The first is that I am functionally immune to chastisement from individuals who don't know me particularly well. With very few exceptions they aren't able to articulate grievances or counter arguments beyond an emotive blithering that is tied to a loathing of their own inability to affect my opinion.
The second is that I care almost nothing for the emotional contrivances, brand tribalist attachments or self-aggrandizing self-importance of others. I recognize that many people need to think of themselves as special, or superior or somesuch. I don't particularly care. Nor do I care if speaking the truth as I see it hurts their feels. Evidence of superiority or GTFO.
The reason this flows from my own self-awareness is simply that I've had to come face to face with my own utter irrelevance. In the grand scheme of things - hell, in most day-to-day circumstances involving even the most important people in my life - I am meaningless. Utterly disposable and replaceable. A "cog", as it was so rightly put.
Being a replaceable, disposable cog is my job. It is inculcated into systems administrators from day one. Our whole existence is based on the concept of risk management. Hundreds of times a day we have to make decisions where "how can this be maintained if I get hit by a bus" is a fundamental consideration.
Systems administrators spend their entire careers engineering themselves to be disposable and replaceable and automating themselves out of a job. It's ground into us at every turn. We spend our careers working out ways to replace everyone else, too. We see the world and all it's people as little more than the tasks they complete and the manner in which they are completed.
"Rock stars" that stand out are bad. They are hard - if not impossible - to replace, and that makes them a stability threat, if not a security threat.
Now, if you want to sit there and believe that someone trained almost since birth to think of themselves as utterly disposable is "full of themselves" you go right ahead. You are, in fact, merely reinforcing my entire point about developers.
My disdain for developers is something that has been earned over decades. Maybe if you spent a little less time trying to prove how you're such a special snowflake and more time coding unit tests you'd be able to start reversing that opinion.
Unless what you code is so perfect, so well designed, co complete so flawless and filled with exception-checking and error handling that it can stand on it's own - and there are damned few developers who can do that - then being a unique special snowflake is a hindrance, not an asset.
If you don't like that I point that out, too bad. If you don't like that I don't respect developers, too bad. Respect is earned. it is not a default setting.
In 20 years of doing this I have learned the hard way that the overwhelming majority of developers are threats to security, to stability, to unit cohesion and to the success of ongoing operations. They need to be carefully risk managed.
If you want to call that being full of myself, go right ahead. I call it learning how business for beginners. Now, if you want to get into the care and feeding of sysadmins, I'd be glad to discuss all the risks they pose too, and the special considerations required to handle them.
