Given all the compile to JavaScript projects and even video decoders running in JS, I wonder why there is still no chip capable of executing JS on pure Silicon. Since the standard is a very slow moving target, that should speed up all Web applications a lot making it a considerable business case.
We'll eventually see chips optimized for JS execution. It just takes a while. It took a long time for H.264 (video) decoding/encoding to be built in to the hardware.
JS is also a general purpose language, but there's still plenty of potential for hardware optimization.
