I love how some programming languages allow you to express your intent on a high level, while others put almost no boundaries between you and the machine. But looking at the architecture of large-scale systems, I feel the choice of language almost doesn’t matter at all

How many large-scale systems written in such programming languages have you actually studied?

Honest question. Also what languages? The large-scale systems we’re writing look significantly different from those written in traditional languages.

My guess is we have different definitions of what a high-Level language is, but you are right in that I’ve never studied or reviewed a large-scale system written in e.g. Haskell or ML. I’d love the chance to do it.

Always happy to show you!
