Every time an engineer evaluates a language that isn’t “theirs,” their brain is literally working against them. They’re not just analyzing technical trade offs, they’re contemplating a version of themselves that doesn’t exist yet, that feels threatening to the version that does. The Python developer reads case studies about Go’s performance and their amygdala quietly marks each one as a threat to be neutralized. The Rust advocate looks at identical problems and their Default Mode Network constructs narratives about why “only” Rust can solve them.
We’re not lying. We genuinely believe our reasoning is sound. That’s what makes identity based thinking so expensive, and so invisible.
— Steve Francia, Why Engineers Can't Be Rational About Programming Languages
