alt Hacker News> Rust is not and has never been "make literally everything safe", it's "push the unsafe boundary as low as possible and keep as much as possible above it so that you can reduce the surface area for unsafety and more easily find bugs in the unsafe code".
Another definition: Rust is a lang to "Run fast and low-level software/firmware, with nicer tools, features, and syntax than the other langs which can do this"!
Obviously, the value proposition you find in this case depends on the subjective nature of that regarding rust vs zig!
I don't think I agree with this framing because "definition" implies comprehensiveness in a way that "here are some properties which may not cover everything that's relevant" does not. Your "definition" implicitly ignores the safety mechanism that Rust has and Zig lacks, which does a lot of rhetorical work into making it seem like the only difference is in "flavor" rather than "substance". My argument that there is a meaningful difference in substance, just not the one that the parent comment (and plenty of others) expected.
