> Languages like Lisp, Clojure, Rust, Haskell, Erlang give strong engineers room to build powerful abstractions ... You live in "someone new is trying to understand what the last person did".
In a language like C++, Rust or even Haskell, those "powerful abstractions" are mostly about building libraries, not application code. You still benefit from powerful libraries that were built as part of the ecosystem, even while keeping your own application code simple and intuitive to ease onboarding of new coders. Part of the "powerful abstractions" is to enable a "hand-holding and guard rails" approach for application code that's going to interface with that full-featured library.
