Yes, while macros simplify some tasks, they also make it harder to really understand the code. Well, technically they hide the code in most languages as they're metaprogramming done in a separate language.

I love Rust and do some advanced code sometimes, but very rarely have I created a macro. I still see it more or less like "magic" that "super-human" library developers master to make their life easier. Typically not my use case.

This is another advantage of Zig. As you may know, metaprogramming in Zig doesn't use any special syntax, but rather the Zig language itself. This is often known as comptime and while not necessarily easy to grasp, as you're reasoning about compile time stuff, at least it's done in pure Zig.
