Re: On the cusp...
We're already there. A lot of websites are following in Google's footsteps with their one-page all javascript runs-in-the-browser nonsense. Other than purely cosmetic features and some specialty stuff like WebRTC, javascript and other browser delivered executable code has done nothing except introduce a lot of security vulnerabilities.
I wonder how much electricity has been wasted worldwide over the last decade because of browser scripts. I bet it's at least in the terajoule range.
