Consider Electron if it shipped with only v8, wasm, and a builtin canvas-style buffer without the rest of the HTML trappings. You now have a UI platform that is safe, performant, and (most importantly) runs everywhere the same way.

The web is creeping closer to becoming a Java that actually works. In another decade, we will have come full-circle. Someone will have the "new" idea of adding a declarative layer (maybe with some XML-like syntax) that can be translated to canvas. While the few remaining old devs will remember, all the new devs will jump on this "emerging technology" and we'll start re-inventing anew.

And so the wheel turns....
