Nightly Rust is also "currently released and available," and a significant part of the ecosystem can take advantage of it.

Besides, the vast majority of the work to close the gap between C and Rust in the benchmark game was from people optimizing the benchmarked programs, not from any language or compiler changes. There is no inherent 2x slowdown in any meaningful sense.

The inherent 2x slow down just works out to `__m128` vs `f64`. C can double Rust's FLOP thought-put.

The fact function calls, if statements, passing variables to functions is identical speed to C is lost on the parent poster. These core points prove the Rust/C are equal speed.
