My experiences with IT across multiple organizations is that they're understaffed and not hiring particularly competent people.
The competent people they do have are generally egomaniacs because they're the only person or persons in a department full of idiots, and they deal with idiots all day, so they assume everyone is an idiot.
Additionally, IT is SUPER territorial. Like, noticeably so. They have 1-2 people that know what they're doing, but their whole staff acts like they're as smart as their smartest person, which they are, unassailably, not. I give a lot of respect to the competent and knowledgeable ones, because I realize they're also managing a bunch of idiots that don't know they're idiots.
Across three different organizations, I've watched five members of IT fired for their arrogance. If you're interested in doing this, simply hire an attorney, bring the smart person into the room with the arrogant idiot, and make it clear that someone in that room is not going to work for the organization in two weeks, and then explain the situation.
If you feel attacked by this, you're one of the idiot IT staff. I'm good friends with our current CIO and security lead. I hate to break it to you, but they don't like you either. You are described as "cannon fodder for grandpa."
Easy to fire, easy to hire. This cartoon adequately captures the level of questions that incompetent people working in IT can feel superior about. But they're not serious IT issues within a large organization.
That's why you hire kids that graduated with "computer degrees." So they can make cartoons and catch all the bullshit, while the real professionals do the real work.
