It's the attitude of the Angular 2 team that makes me glad I decided to choose Aurelia instead. Nobody seems to realise that Angular 2 exists first and foremost to meet the needs of Google's internal Green Tea team and not the public.

This is just one of many things that should make people think twice about using Angular 2. The fact the team seemingly take input from a select handful of "Google experts" to guide the framework should be an alarm bell in itself. NG2 is a monolithic and over-engineered framework backed by a company who have proven they conflict with themselves (Polymer) and deprecate popular services on a whim (Google Reader).

I personally use TypeScript in my Aurelia applications, but I think you should allow developers to write using straight-up Javascript. We're getting to the point (or if you're writing evergreen focused web applications, you're there now) where we will be able to write Javascript without a transpiler soon (for most things).

I love TypeScript, but we can't forget what it's a subset of and some have the view that Javascript doesn't need types or interfaces.
