Adding to your point, I also instantly regarded Amber as an alternative to other higher-level languages. Especially scripting languages that require elaborate ahead-of-time setup. Amber will surely score some points here due to its portability in the Linux world. But other commenters seem to see it as an alternative to writing Bash scripts. So which will it be?

This is not even remotely an alternative to Rust, nor is it intended to be. It's a replacement for Bash.

I know, but it looks like it is heading in that direction.
