I'll stress that it's early days for Dart. Go was announced in 2007 and only this year is going to a version 1.0. I don't know what the timeline is for Dart but I will say this: 1. If anyone is capable of the long sort of time frame that something like this can benefit from--event requires--it's Google; 2. If there is anyone who's qualified as a domain expert in Javascript generation it is, by virtue of GWT, Google; and 3. If there is anyone who's qualified to speak to the limits of what you can do with Javascript it is, by virtue of Chrome and V8, Google. If anything, I believe the error here (if you can call it that) is failing to properly set expectations and communicate the goals of the language (as witnessed by all the comments on this thread from people who were expecting something more and/or different).
