This article is more about having a common culture than about different programming languages. If the author was in a Node.js shop, or a C# shop, or a Golang shop, it would be whatever language everyone is familiar with that would win out.
Having said that though, some languages prevent themselves from being used for "Everything". Python, Perl, PHP, Ruby for example often needs to be paired with another language for performance reasons.
The ergonomics of "modern" compiled languages is good enough for everything now.
I've been using Go for everything for many years now, and it's fine. I know people/shops who use Java or C# for "everything", and it's fine. Fine here being defined as "not needing to learn another programming language to solve my problem".
