I think we missed the boat -- the focus on fancy rendering rather than on the actual data/content set us back years in functionality and helped create free and for-pay walled gardens where actionable data stays server-side and rendering is forced upon us, rather than just having reasonable defaults and then having rendering (incl. multi-modal interaction, etc.) further guided by user-defined settings and heuristics. Even if data happens to be rendered client-side in an SPA, it's done though application-specific means. I suppose deep-learning based data-extraction from free-form pre- and post-rendered content will eventually make up for this, but at least part of that road may have been avoided -- and of course we're probably going to have to pay someone (one way or another) for the privilege of having the content un-rendered back into actionable data at scale...
