Rust’s New Math API Is a Beautiful Trap
Rust’s new portable SIMD API for floating-point math is a genuine breakthrough for performance β and a trap disguised as progress. As Intel, ARM, and RISC-V multiply their vector instruction set generations, every clean abstraction becomes a deferred maintenance nightmare. The faster your code runs today, the more brittle it becomes tomorrow. This is the real cost of fast math that nobody’s talking about.
