That's a surprising comment to read as someone's who's immersed in making web apps in JavaScript that work great offline and synchronize data when possible. For me, sites that require network roundtrips for every state change are often near unusable. Instead, with JavaScript and AppCache/ServiceWorker, I can make web-delivered programs with instant response times, intelligent auto-updating, and so on. 2 MB of application code isn't too bad when you can download it once on WiFi and then never need to touch the network again.
