>Your own examples in your edit literally contradict what you say as you chose langs with extremely divergent concepts. C# and Erlang, Rust and C. You missed haskell and lisp.

How so?

You can learn and understand concepts implemented in Rust without learning Rust

Concepts aren't just "learned" by reading about it. True learning requires internalization. Internalization requires practice. Practice requires the concepts to be applied. Application requires real world tools. Usage of tools requires one to learn about the tools.

If the only tool available is rust, then one must learn rust to truly learn the concepts related to it.

100% agree. And the Rust compiler is a great way to internalize those lessons since it shows what you got wrong, where you missed an ownership assignment, and often telling you how to fix the problem in plain English. It's as close as I've found to an actual teacher while writing code.

When the compiler stops yelling at you all the time, you'll get your feedback that you've actually learned those lessons.
