> I do NOT think that Electron or the HTML/CSS/JS stack has an inherent advantage over other display technologies

If you want the real answer, it was all driven by responsive design and CSS. Qt tried to bring that to native apps and failed miserably. Modern devices need apps that work the same across any screen/window size, any aspect ratio, any resolution, support accessibility features, etc. The list of things you get out of the box with a webview is massive and only growing. Any attempt to clone this while ignoring W3C specs and browser quirks will fail.

I can't think of a more heroic and crazy uphill battle than managing to decouple CSS from HTML and JS, and get app devs to like it, and get users to like it.
