“engineers disease”: The delusion because you’re ubercompetent in your chosen field, you’re automatically an expert on everything else.

I think that’s only part of the problem. Experts in other fields normally do not impose their will upon all domains of knowledge like tech people do. At least not to such an extent. I think them being paid better wages and benefits than other workers with the same depth of expertise is what makes them like this. Financial success is conflated with objective superiority.
