Intel and HP attempted to deliver what this paper advocates. They designed an entirely new processing element and compiler architecture that promised to deliver high performance with less complexity. It was called EPIC and manifested as Itanium. Billions of dollars and the best minds at the disposal of an industry wide consortium couldn't make it work; one year ago the last Itanium shipped. The market has spoken.

You can run unmodified, compiled OS/360 code from the 1960s on a z15 machine built this year. The market values the tools and code it has invested in far more than any idealized computing model you care to speculate about.

The flaws in contemporary CPUs that device manufacturers perpetrated on their customers for almost 20 years are not the fault of C and its users. They are the fault of reckless manufacturers that squandered their reputation in the name of performance and, ironically, helped perpetuate the lack of innovation in programming techniques called out in this paper.
