These Rust replacements are unique in the way that most of them vastly improved on the original. I still don't quite understand what about Rust made that happen. They could have been easily written in, say, Nim years before Rust existed.

Remaking traditional UNIX tools is a common exercise when learning system programming.

And because Rust is quite trendy nowadays, I guess a lot of people wanted to try it out, and in some cases, that exercise turned into a viable product. Nim never got the same popularity.

Systems programmers got really excited :) I don't know much about Nim but I don't think it, or Go, etc. are aimed as low-level as Rust is. Rust is pretty unique in being as low-level as C, yet providing safety and higher level abstractions.

Nim is aimed at pretty much the same level as Go, I would say. Only with more modern abstractions.

And currently (with Nim 1.4 and its memory management), it's moving towards Rust's field. Their performance has always been in the same space, especially regarding cmdline tools, where latency is more important than most other tools.

Nim has very easy ways to get full C performance in pure Nim with a trivial FFI to just call C and is both higher level than Go and lower level at the same time because of that. Simple analogies often fail to describe. :-( { This is not intended as a dig/criticism but note on communication limits - you should just learn more about Nim at https://nim-lang.org/ }
