The comparison isn't with rust today, but the long term differences between the languages. Rust has a straightforward path to rectifying the standardization issue and enough community momentum to succeed.
For example, Rust has an in-progress specification, here's the (currently empty) repo: https://github.com/rust-lang/spec. There's also MIR, a de-sugared internal representation that's sufficiently well specified to build formal models of (see https://github.com/rust-lang/a-mir-formality and https://github.com/rust-lang/miri), as well as the ferrocene spec (https://spec.ferrocene.dev/general.html) that's suitable for certification authorities (if not actually useful) and of course the rust reference/RFCs that are actually usable by people.
Plus, the fact that everyone in the rust community has standardized on one compiler and one package

manager (for better or worse) means that the language team has a much better insight into specification breakages than the ISO process of languages like C and C++.
I can start writing stuff today and be confident that any changes will be minor if necessary when the language catches up.
I'm more than happy to have this discussion over email if you want to move it off HN, too.
