Ask HN: Eli5 why Angular 2.0 is getting negative attention

Could someone explain to me why it seems like a lot of people have a negative view of Angular 2.0? I have a very basic understanding of Angular but I was planning on taking a deep dive and learning the framework in the next couple of months. I honestly hate the idea of learning Angular now and then having to relearn everything once 2.0 comes out.

Since I don't have a solid understanding of Angular, would it be better to just go all in with React and focus on learning that instead of Angular?
