Maybe I'm not that deep into programming, but I don't understand the hype about Zig?
I programmed in rust a bit and can't say I'm an expert, but in my view rust mostly-solved the memory management problem at compile time and without a GC, and it works very well. The biggest con and cost I've always seen repeated so far is that "it's slow to compile", and I get that, if you're past 250 crates the final --release link tends to become noticeable, but there were improvements to incremental compilation.
On the other hand - looking at the syntax from this post - Zig feels a blend of javascript, python and golang syntax that still requires memory management. So a nicer-written C that inherits all the issues from C? From the post: no functional programming, data mutation, memory leak, double-free, memory corruption.
Personally I'd rather trade a couple minutes of final link every time when this is the other option.
Zig is aiming to be lower level than Rust. As the project homepage prominently advertises, it has no hidden memory allocation or control flow. It also gives more control over how memory is allocated, which is potentially useful in applications with particularly tight performance requirements.
Kelley first created Zig when hr was working on a digital audio workstation and found most existing languages to be awkward for working with particularly hard real time requirements, but still wanted something more modern than C. Im speculating here, but I believe its advantage over Rust for that specific application is that you have tighter control over exactly when memory is allocated and deallocated, and how data is laid out in it. Rust wants to tie allocation lifetimes to scope in a very fine grained way that I would guess is beneficial the vast majority of the time, but does still make it harder to reason about when you’re about to stall out the CPU while the allocator does its thing.
Zig and Rust are equivalently "low level". Zig isn't any closer to the hardware than Rust is.

Rust gives you all this, too.
Zig's primary (possibly only) advantage over Rust is that it has much faster compilation times.
Comptime is a big one too. You can achieve similar things in Rust with generics and macros, but comptime makes certain things easier (and other things harder).
