Whither Warhol's law? [embedded computing]

The article discusses a law concocted by the author: "Warhol's Law of Computer Systems Architecture." This law stated that every computer architecture would be the price-performance leader for 15 minutes. The author was thinking mainly of workstation CPUs, but he believed the embedded CPU market would follow suit. Embedded systems provide an ideal forum for CPU competition. A lot of people seemed to want to design CPUs, so the author reasoned that no end of new competitors would appear to introduce new features and drive down prices. It hasn't worked out that way, however. The high-end market has several players, but not the profusion expected a few years go.
