In this case, `asm.js`, which was the original the core technology that made any of this possible, was released in 2013, which is ancient in this day and age.

It's normally very fast from technology to creation of the initial product to wide-spread adoption (typically about five years from release of the first version, per my blog post). So more likely if this does happen, it will require another core technology breakthrough, e.g., `asm.js` (now WebAssembly) isn't enough to facilitate it on its own.
