Well, the same was believed about the ASM vs C or C++
compilers. This too was infirmed, at least at global scale,
with time. Very specialized applications would still perform
better when in ASM (I believe).
Only when exploring vector instructions or when targeting simple
processors.
I seriously doubt someone can hold the Haswell ISA in their head
as we did back when targeting the Z80, 6800, 80x86 (up to
Pentium) and similar.
