I wouldn't dare expect this to exist in 5 years, but I hope maybe it's an issue slightly closer to the front of our minds. We really don't need, or even want, a wholesale replacement of the browser internals - the rendering engines, sandboxing techniques, etc. are good: all I'm saying is it would be really, really nice if we could have access to these components at a lower level (not too low, mind) than what we've currently got.

I'm fine with JS as a thing that exists, my problem is with it's position as the "assembly of the web" (credit to user Lerc below for that fine phrase.) The good parts of the HTML/JS/CSS paradigm are making awesome things, but the bad parts make our lives far more difficult than they need to be.

And don't worry, I'm not actually going to kill myself, but thanks for the concern.
