I feel this needs to be said about most frameworks these days...by the time anyone agrees on anything, a new framework will come along and everyone will start praising it as the new holy grail.
I'm so glad I did not follow though with an Angular project about 2 years ago. It would have failed miserably and been difficult if not impossible to manage at this point.
What is your last point exactly? How a new version of Angular would have made your project fail so miserably?
Change is great, it makes awesome things happen. New frameworks are here to give you a choice, you don't have to use all of them. Angular2 will come with a lot of new features and Google said that they will keep working on Angular1 until most of the users switched, what's bad about that?
The fact is, there's always a new tool for the job a year or two down the road, but software needs building today.
I launched a major internal admin a year ago with Angular and it's largely on autopilot because Angular is so darn easy to work with when it comes to building new features, especially in the view layer.
