Seriously, if you like and use AngularJS and based on something tangential like this Dart announcement, you decide to switch to Ember, which honestly is not that similar.

Like someone said, you/we can always decide to fork project, but again... let people who care about Dart try to do it, I think this is legitimate prof of concept. I don't think it will catch up, if there is genuine work outside Google on Angular.

I am grateful for good work done on Angular project and look forward for new features. I will not use Dart that is for sure.
