Unfortunately, due to the complexity and specialized nature of AVX-512, such optimizations are typically reserved for performance-critical applications and require expertise in low-level programming and processor microarchitecture.

nice.

can usually get a pretty good performance increase with hand writing asm where appropriate.

don't know if its a coincidence, but i've never seen someone who's good at writing assembly say that its never useful.

To be fair, people who don't find assembly useful probably wouldn't get good at writing assembly

for sure, its perfectly reasonable to say "this tool isn't useful for me"

its another thing to say "this tool isn't useful for anyone"
