  in the near future, we'll be using CPU's with 100's or 1000's of 
cores. see e.g. this;


  on such hardware, it'll be (almost) completely uninteresting how much 
CPU time we spend. the important thing will be to parallelize 
everything, and we can take for granted that parallel execution will 
"pay off". software technologies that doesn't makes this happen under 
the hood will be the COBOL of 2010's.
