There's also that realization that compiler & software development is still far, far behind the parallelization capabilities of the HW. See the failed DEC Alpha, Itanium. It's a bad design situation when compilers regularly generate code that blows caches, branch predictors, TLBs and instruction pipelines more than 50% of the time when the code has been run through aggressive non-PGO effort. Compilers need to get better at generating better code.
