Is PHP still a relevant language in today’s day and age? I know a LOT of languages and it just never occurred to me to learn this one, because anyone I’ve ever been aware of writing a backend these days would either choose Node or one of several compiled languages. Lemmy uses Rust for it’s backend which is highly desireable, many people would have used Golang in the backend world if they desired performance and compilation, otherwise I don’t know why you wouldn’t just use Typescript. Makes it hard to contribute to IMO.
Reddit was originally built in Lisp – Paul Graham, an early backer, is super-rabid about Lisp. They eventually reimplemented it in Python.
I do agree that it’s not the norm, though.
