Why learn Latin in 2018 if you’re not a member of the catholic church? Or Greek if you’re not greek? Well, both are great at putting things in context and highlighting commonality: Latin does this for the romance languages and Greek does this for much scientific terminology. And, Ed, a 46-47 year old positively archaic text editor, does this for parts of the Unix userland that are still very much in common use (specifically sed, awk, grep, vi), as I learned from reading Michael W Lucas’ new book Ed Mastery.
