The reason why cli commands are written in C is the fact that the OS is written in C. There is a lot of inertia, because it is more efficient to have the operating system and the tools for it written in the same language. We may be entering a transitional phase with new tools written, old tools rewritten in Rust. Some of the innovation or simplification highlighted in the article remind me of the chaos of the Unix wars which led to POSIX. I wouldn't chuck out the tools we have though. Modernise them, but keep their functionality. What many critics of CLI tools do not realise is that there is a lot of power hiding in that complexity. Familiarise yourself with xargs or parallel commands to see that quite often learning them given you results faster than reimplementing them.
