Compile times will likely improve in the future, but they're still likely to be much longer than those in zig. Especially if you also consider the body of software surrounding zig/rust. I believe zig developers are more likely to take a stance that libraries should be more specific and smaller, while rust libraries tend to be more all-encompassing. Even if the resulting code is small and efficient, the compiler has to do more work.

I think Bryan Cantrill had a pretty spot on description of this kind of thing in his "values" talk, even if zig is not on his list.
