I like the prediction, but I think the biggest hurdle to compiled javascript will be mobile browser usage. The javascript interpreters in the mobile browsers right now are dog slow compared to their desktop cousins.

Android 2.2 and later uses Google's V8 JIT. iOS 4.3 and later uses Apple's Nitro JIT. Firefox 4 and Opera 11 also have JIT compilers enabled for ARM devices. Mobile processors are still slower than desktop ones, of course, but JavaScript on mobile today is already faster than JavaScript on desktop just a few years ago. For example, the benchmarks on http://arewefastyet.com/ http://arewefastyet.com/ show V8 running only about 5x slower on an nVidia Tegra 250 ARM board than it does on an Intel Core 2 Duo Mac Mini.
