I disagree, I think the future will be all kinds of things, both on the web and elsewhere. On the web, it will be both handwritten JS as well as compiled JS from various languages like C/C++ (into asm.js), TypeScript, etc. Each of those is good for some use cases, but none is good enough for everything. Just like we have many languages for native development and web servers and so forth.
