Nice read.

I'd just like to add that there is already architecture in FFmpeg that
is entirely optimized on intrinsics - AltiVect. There were few
fundamental problems with it and I'm not sure if they have been
successfully solved. These include things like generating code that
picks up processor SIMD dialect at runtime.
