I keep seeing job postings bragging about how the org uses “modern tools” and then proceeds to list Node.js and PostgreSQL.

Node was first released 16 years ago, in 2009. PostgreSQL was first released 29 years ago, in 1996.

I’m a LISP user so I have no problem with mature, robust, high-quality technologies. But there’s no need to pretend that they’re the flashy new thing.
