This trend has been true since the 1980s where people wrote key 
routines in assembly. Meaning, most projects aim for usable at 
lowest price. More capable computers means less efficient 
programming...

I think a better argument is that system level programming 
requires predictable latency and high effiency to a greater 
extent.

For instance, if I create a solar powered monitoring system then 
I want to use a low powered cpu.

Walter says D is for systems programming. Well, then it follows 
that everything in the standard library should be designed for 
that purpose.

Meaning: predictable latency and highest efficiency, either by 
being fast OR consume minimal resources (energy or RAM).

If D does not follow through on that then it cannot be considered 
to be a dedicated system level language. But then D needs to 
define what it is for.
