Zig vectors do not necessarily force data into SIMD registers; a scalar implementation would work equally well. This is not just a theoretical argument, because Zig code that uses `@Vector` also has to compile for architectures that do not have SIMD instructions. That being said, the parent commenter is actually referring to other recent proposals as opposed to existing `@Vector` functionality: https://codeberg.org/ziglang/zig/issues/32032 https://codeberg.org/ziglang/zig/issues/32032 https://codeberg.org/ziglang/zig/issues/35376 https://codeberg.org/ziglang/zig/issues/35376
