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.

This sounds like any standard FOSS work flow. Why are they calling it hand written code? Is that just an affect of the normalized buy start up, use code, ruin code, spin ruined code's bugs as features, release to public without any tech aupport more than a cheap ai bot to handle ruined code crashes, throw out purchased company's asset and on to the next.

Or am I missing something I'm to IT dumb to understand?

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.
