I'm not convinced Rust would ever be the right "everything language". Currently I find myself reaching for it for almost every domain, largely thanks to the ADT's and amazing tooling, but it's a bit low level and sometimes tedious for certain sets of applications where more approachable languages, like Python and JS currently are the standard bearers. Personally I think we would get really far with Rust, and some yet-to-exist higher level language with a modern type system built on top of the Cargo ecosystem. Then maybe C and/or something like Zig for niche applications where extreme memory efficiency is the main constraint.
