This is absolutely not what the article is about. A good majority of it is spent on the myth that Zig is safer than Rust, which has nothing to do with wishing Zig was more like Rust.
Is there a myth that makes that claim? Virtually every take I've heard is that Zig is "safe enough" while giving developers more control over memory and actually, it's specifically better for cases where you must write unsafe code, as it's not possible to express all programs in safe Rust.
If you must write unsafe code, what's wrong with just dropping down to unsafe in Rust when you need to? You have all the power unsafe provides, and you have a smaller surface area to audit than if your entire codebase resides in one big unsafe block.
Zig has a C and C++ compiler built into it and works seamlessly with it. Several C/C++ projects use Zig as a build tool. Zig makes different trade-offs with C++ from a language design standpoint. C++ has a lot more footguns to create UB in the first place.
WTH they were talking about Rust and Zig, they did not even mention C++ and you come with "if your metrics is blah then C++ is superior, checkmate!", completely ignoring C++ is a monster of complexity while Zig is basically simple as C.
This is precisely the myth that the article talks about. Miri finds significantly more UB in unsafe Rust than Zig's checks do.
Even if it weren't, this exaggeration is a complete theater. You aren't supposed to use unsafe Rust unless you really have to. I have been using Rust since 2020 and I've used it once, for 3 lines of code. The entirety of all Zig codebases is unsafe. That's fine if you are fine with unsafe code, but this myth is dishonest, and I take great issue with using a language where the founder is the primary source of the dishonesty - because what else is being swept under the rug?

That's not a substantiated claim. Miri also runs very slowly.

Cool, glad you haven't needed it. If you're ever writing interpreters or interfacing with external code, you'll need it.

Zig is not 100% memory safe but it has compile-time safety features for vast majority of problems developers get themselves into with C/C++. Meanwhile, Rust's safety overhead has real trade-offs in terms of developer productivity, computational performance, compiler performance and binary size.
It’s harder to write correct unsafe Rust than correct Zig because (1) Rust uses references all over the place, but when writing unsafe code you must scrupulously avoid “producing” an invalid reference (even if you never deference it), and (2) there’s lots of syntax noise which obscures what the code is doing (though &raw is a step in the right direction).
Various modern alternative languages can claim to be "safe enough" or safer than C, along with C interop. Nim, Dlang... In fact, the V programming language (Vlang) can make the argument of being even safer, because it has more default safety features and an optional GC (that no libraries depend on) for greater memory safety. That and it being designed to be easier to use and learn, for general-purpose programming.
The article, in its review of the Zig language, goes after its marketing history and broken promises (calling Andrew's statements fallacious and worse) for attempting to portray itself as safer than unsafe Rust, the distortions around UB (undefined behavior), etc... As a consequence of the demonstrably valid test results and being tired of unreliability, the author stopped using Zig. It should also be mentioned, that v1 Zig is nowhere in sight, so likely many years more to wait.
