FFmpeg devs boast of up to 94x performance boost after implementing handwritten AVX-512 assembly code (www.tomshardware.com)

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.

The point isn't that it's handwritten code, it's handwritten assembly. All code is written by hand to some degree, but it's normally in a higher-level language and compiles down to machine code. Assembly is basically as close as you can get to the bare hardware in terms of control.
