The corollary is that after a best/good-enough solution is found and the underlying platform unifies and stabilizes, most of the innovation moves up in the stack. Things that used to be important and hotly debated become mundane things that you can rely on simply being there, a new space then opens up for new types of software to compete in, and the pattern repeats. See hardware architectures -> operating systems -> browser engines -> frameworks -> services etc. The first two are effectively fully commoditized, few people get excited about them anymore, even as Linux development is more active than ever. Similarly the browser engine is now entering the unification phase, with Chromium swallowing competitors. Meanwhile the battle to define how higher level components are created on top of the browser is in full swing with rapid innovation.
