This is a pretty important point to consider. If Google was as invested in Angular as Facebook was in React, they would probably have gone with a more gradual, methodical approach to improving the framework (like the Ember team did). And until that changes, there is very little stopping them from doing another mostly incompatible rewrite in a few years. As it stands, Angular 2 is closer to a completely new framework roughly inspired by Angular 1.x than a new version of Angular.

This is a nice worldview but doesn't hold up to the evidence. Google has said they have something like 10k Angular 1.x apps, so they will keep on working on Angular 1. Angular 2 happening along this support is showing that they're willing to invest in the conservative route and the "burn down the libraries" route at the same time.

  By level of investment, both me and the OP meant in terms of products that are key to the company's operations, and need to be continuously supported and improved. Facebook is one such app for Facebook that uses React. Instagram is one such app for Facebook that also uses React. I honestly don't know any such app for Google that uses Angular. Until that changes, there is very little incentive for the Angular team to keep improving upon the existing solution instead of building something completely new with no regard for the people that depend on it. The so called upgrade path they offer for Angular 1.x is a complete joke. That you can "mix Angular 2 into your existing Angular 1 application" would be a true statement with any component-oriented framework in place of Angular 2, like React, and Ember. And this was not true for Ember just a few months ago, which is living proof that gradual improvement can in fact be accomplished with any framework, but of course, throwing everything away is much easier, so the framework developers need to have strong incentives to not do so.

    Angular 2 is the framework for Google's AdWords products. So it's core to how Google makes its money.

    Google uses Angular in over 1000 internally and externally facing apps, including some on Angular2 already. They are also on the main trunk, and update on commit. The test suite for Angular at Google actually checks not only the Angular tests, but also all of the tests for all 1000+ apps at Google that use Angular, before allowing it to be deployed.
