Having skimmed it, I had the opposite reaction, the wording is clunky in a way that I haven't seen LLMs do, it feels very human to me.

Stuff like

> Also the learning curve for Zig can be steep, especially for those unfamiliar with low-level programming concepts.

I don't think an LLM would start a sentence with "also" like that

> The small and simple syntax is an important part of the maintenance, as it is a goal of the language to allow maintainers to debug the code without having to learn the intricacies of a language they might not be familiar with.

The wording here feels like someone who's a fan of Zig taking a sentence praising Zig's design and trying to rework it into a slightly more neutral encyclopedia style.
