The issues I have are that developers tend to be bad at communicating even with each other. Communication as a discipline is a lot about meeting people where they are and this is difficult for basically everyone. The antagonistic attitude that developers seem to develop happen across almost every technical discipline whether it’s engineering or even trades. It may be even worse in trades given so much contact with the general public. If developers had to do customer support for their products as a rule you bet they’d get grumpy. However, I’d also say that interacting with the public probably makes most people in US retail grumpy, too.

What I think I’m trying to say is that developers self-selecting out of things thinking they’re either not good at them or because they don’t like to do them is a bit of a luxury compared to most professions and many on the outside would look at that and feel there’s an attitude of arrogance and entitlement as such.
