You can try to get there by bringing the benefits of the web to apps, and by bringing the benefits of apps to the web. We're already seeing this with ChromeOS, FirefoxOS, Cordova, etc. on the web side, and various efforts to streamline app installation, add deep linking, and other things on the app side. Personally, I think browsers can be a quite good application platform - they're basically a view hierarchy, with a layout and styling system, an event model, and scripting engine. With efforts like the *OS APIs, custom elements, asm.js/PNaCl/Dart, WebGL, canvas, Service Workers... there's a lot you can do, all in a stack that's easily accessible to millions of developers.
