Operator is a monospace typeface from Hoefler&Co

From typography.com:

About two years ago, H&Co Senior Designer Andy Clymer proposed that we design a monospace typeface. Monospace (or “fixed-width”) typefaces have a unique place in the culture: their most famous ancestor is the typewriter, and they remain the style that designers reach for when they want to remind readers about the author behind the words. Typewriter faces have become part of the aesthetic of journalism, fundraising, law, academia, and politics; a dressier alternative to handwriting, but still less formal than something set in type, they’re an invaluable tool for designers.

I’ve dropped Operator Mono into both Sublime and Terminal. A monospace typeface needs to be readable and without a lot of opinion. After brief usage, Operator Mono easily meets both requirements.
