We did that to ourselves, picking languages like football memberships assigned at birth, with religious fights on the playground.

Not only languages, editors, OS, hardware platform,...

Because when it comes to apply for a job, the HR drones don't understand that one can manage to program in more than one language, use more than a specific OS, and so forth.

It was to be those specific bullet points, and by the way at least during the last five years exactly before applying to the position.

There are also the trivia questions during the interview about obscure language features.

So this naturally spills into one's identity, going back to the primitive mind of the days humans lived in small groups and it was us versus them across all tribes.

Which for those of us that are generalists, is a big pain in some body part.
