The thing is, I absolutely love programming languages. I work as a graphics and video game developer, which is thrilling and challenging work, but secretly I would rather be hacking on compilers. I love languages because, of everything I’ve encountered in computing, languages are by far the weirdest. They combine the brain-bending rigor of abstract math, the crushing pressures of capitalistic industry, and the irrational anxiety of a high school prom. The decision to adopt or avoid a language is always a mix of their perceived formal power (“Does this language even have this particular feature?”), employability (“Will this language get me a job?”), and popularity (“Does anyone important use this language anymore?”). I can’t think of another engineering tool that demands similar quasi-religious devotion from its users. Programming languages ask us to reshape our minds, and that makes them deeply personal and subjective.
