At the Angularconf 2016 Matt Davis from Mediacurrent discussed the collaboration between the Angular 2 and Drupal communities. Currently Drupal is missing a comprehensive front end framework and is looking at coupling together with Angular to provide a more contemporary administration editing interface.
Drupal and Angular communities are forging a relationship that might have a significant impact on the future of both systems. It seems like a good match to couple Drupal 8 with Angular 2 as both have gone through large changes in the future, but Drupal 8 still lacks a coherent de-facto SPA framework.
Decoupling Drupal and working with a front end framework has been a hot topic in the Drupal Community for a while now. Dries Buytaert has discussed the prospects of different options, and has even credited the Angular 2 team for changing their licensing to be compatible with Drupal.
