I think that one day, web apps by default could work, but before that can happen the web must see sweeping change.<p>The lackluster performance and high resource usage associated with web apps is a direct consequence of the complex patchwork nature of each component involved. Quite simply, the web was not designed to be used the way we’re using it, and evolving standards have made browser rendering engines horrifically complex (and in some cases convoluted).<p>What’s needed is a fundamental reimagining of HTML, CSS, and the DOM at minimum with little to no regard for legacy. In the 90s, we didn’t know what we needed but now the picture is crystal clear. Should we use this knowledge to design a new web, I’m positive that the result would be just as open as the web is now while performing tens or hundreds of times better — it’d likely be good enough to make web apps competitive with native apps under a far wider set of circumstances.
