I agree. There is virtually no way you can smoothly upgrade an Angular 1 project to this. You'd have to redo most of it from scratch. There are a lot of huge projects that are built on Angular 1 -- many enterprise products too. And this is a huge blow to maintenance. It might be a reason for a lot of people dropping Angular and going for something that makes more business sense. Maybe it's React's time to shine.

The thing with React is that either Facebook's engineers are incredibly prescient or lucky. React very is really well designed and feels natural with ES6.

It's so incredibly designed, even without the ES6 optimizations of 0.12.0 (coming soon) you can code today in ES6 (I use 6to5 with JSX transformer harmony just in case).

Yeah I am betting on React. I am not a Web GUI developer and learned about Angular and now React just out of curiosity. Well I tried to learn Angular and got stuck at the termology soup of "directives", "digest cycles", "factories", "services", "dipendencies", "scopes". I understand all those English words but I still don't quite have an idea of how they are helping me.

With React somehow the whole data flow and how components work and even JSX make a lot more sense.

Facebook uses React in production (a lot) and has to migrate any code just like you would as a user of the library. Facebook is effectively always running React master.

Facebook also has members on TC39 and is quite involved with evolving the language.
