Yep, the conventional (current) wisdom is that they hit compilers. Itanic was predicated (pun intended) on compilers being able to deliver the parallelism from existing C/C++ apps. It's pretty tragic how this has turned out. Still no mainstream CPU languages that are good for parallelism and all the action is happening in the GPU side with the tragic fragmented mutually incompatible buggy properietary dev stacks (and C++ baggage to top it off), going on for 15+ years.
