You could certainly make an argument that an easier language allows a programmer to reach a certain skill level faster or maybe even reach a higher peak skill level. By extension you could also argue that, by some definitions, the skill level of that language's community might be higher. However assuming you had equally skilled Rust and Zig programmers, I think it is wrong to say that the Rust programmers would require more rewrites to match or surpass the Zig programmers.
