Zig is a very new and immature language. It won’t be kernel-ready for at l’East another 10 years.

a better syntax

That’s pretty suggestive. Rust syntax is pretty good. Postfix try is just better for example.

Zig also uses special syntax for things like error and nullability instead of having them just be enums, making the language more complex and less flexible for no benefit.

Syntax is also not everything. Rust has extremely good error messages. Going through Zig’s learning documentation, half the error messages are unreadable because I have to scroll to see the actual error and data because it’s on the same line as the absolute path as the file were the error comes from

No hidden memory allocation

That’s a library design question, not a language question. Rust for Linux uses its own data collections that don’t perform hidden memory allocations instead of the ones from the standard library.

it’s more readable

I don’t know, Rust is one of the most readablelangueage for me.

Fast compile time

Is it still the case once you have a very large project and make use of comptime?

it’s simpler to learn

Not true. Because it doesn’t have the guardrails that rust has, you must build a mental model of where the guardrails should be so you don’t make mistakes. Arguably this is something that C maintainers already know how to do, but it’s also not something they do flawlessly from just looking at the bugs that regularly need to be fixed.

Being able to write code faster does not equate being able to write correct code faster.

Really great interop with C

Yes, because it’s basically C with some syntax sugar. Rust is a Generational change.
