That’s a general problem with domain experts in highly specialized intellectual areas: everything looks like a nail when the only tool in your toolbox is a hammer.

It also dovetails with what I wrote before and the Dunning-Krugger effect - just like everybody else, they are prone to think they know a ton about things outside their expert domain they really know little about, so come out as a idiots in those things. It doesn’t help that Tech has been glorified in present day society causing a lot of people within it to have seriously inflated egos well beyond what their actual achievements would justify - you see this kind of thing in all “glamour” areas: for example in my experience lots low-level barely-making-ends-meet actors seem to think of themselves as “superior to the common man”.

I like to think most people affected by such delusions about their inherent worth and capabilities get over it as they get older, after life has had the time to slapped them a couple of times.
