I didn’t write that I agreed with said presentation, but it was interesting, and a good take away is that if you have such a scorching hot loop that iterates over megabytes of data, a compiler may not be sufficient even in low-level languages. (Think of video codecs). And the other side, routine optimizations done on cold paths may not be as worthy (the bash line was me exaggerating the effect - but just think of any Python deployment, they are basically that, slow code calling into optimized libs in C and Fortran)
