I get what you saying, this is really a problem for this field. When I started college in 1990, I had spent a lot of time programming and playing around with a commodore 64. Computer science was the 'easy' option for me, so that's what I did. After a semester of observing the types of arrogant people I had classes with, I decided, I don't want to work with people like this for the rest of my life. So I changed my major to another science and graduated. The problem was, there were very few jobs in that field, so I took a job doing something else. I spent years coding on the side, and finally got a programming job, and then a BS in CS. I've often reflected on where this arrogance comes from. My personal theory is that a lot of people, when they show an ability to work with computers, get a lot of positive attention from those around them because most people don't have the patience or inclination to understand machines so well. I think for some this leads them down the path of really building their identity around what they can do. And when you deeply identify with something like that, it becomes very personal. This isn't true of everyone, you can have passion without being arrogant, but it is quite common I believe. Another factor is probably the perceived competition for jobs and promotions. Many think that to reach the next level, or get the six figure salary, they have to out compete others. And this is true, to a point, as the technical coding interview shows. Edit; something related is the 'tribalism' around languages and frameworks, frontend vs backend, os's etc. When you're just starting out, it's easy to become invested in whatever technology you learned first. You'll write a lot of code and become really accustomed to the tools, libraries, building and deploying. It's only when people branch out and spend a lot of time with other languages and frameworks do they start to see the commonality between them. There's been a lot of convergent evolution over recent years imo. I find that people who understand the basics (http request/response for example) are much more adept at debugging, trouble shooting, and jumping between languages and frameworks.
