Yeah, I was too broad there, sorry about that. There are definitely a few fields like scientific computing and HFT that are very good at extracting performance out of modern hardware.<p>Still, app and server developers, by and large, have not been able to do this (and I count myself among them!) We use languages with no support for SIMD, we stick to language implementations without optimizing compilers, single-threaded language implementations are very popular, we ignore GPU computing despite the fact that the die space reserved for the GPU is as large or larger than the die space reserved for the CPU cores nowadays, and so on.
