Definitely. And I also found the title quite misleading. It's the auto-vectorization that this presentation is trying to cover. Compile-time SIMD OTOH would mean something totally different, e.g. computation during the compile-time using the constexpr SIMD intrinsics. I'd also add that it's not only about babysitting the compiler but you're also leaving a lot of performance off the table. Auto-vectorized code, generally speaking, unfortunately cannot beat the manually vectorized code (either through intrinsics or asm).
