I get why you are saying that, but with intrinsics and C++ I can write template functions that compile to any data type(float/double) or any instruction set (SSE/AVX) that can be reused and inlined anywhere in my codebase, and I just let the compiler take care of register allocation, and most of the time the compiler (VC++ in this case) generates very optimal assembly. It's just so far away from assembly for this use case.
