> Most development is done on high powered hardware that makes slow code very difficult to distinguish from fast code, even though you can often get 10x performance improvements without sacrificing readability or development effort. true, but compilers are also doing a lot more, and one big driver of high-performance machines (at least for native dev) is compilation taking waaaay too much time...
