Yeah learning Angular 1.x right now is pretty much a waste of time. I learned it last year and feel like a sucker due to the drastic changes in 2.
One thing that's surprised me is I get nearly as much attention from recruiters for Angular work as for Rails. I think this is mostly due to the .NET world embracing it, they tend to be enterprisey gigs.
Give it a few years, and Angular 1.x is going to be like COBOL in the early 90s. Lotsa code out there to maintain...
The main issue stemmed from research, development, and training costs from what I understand.
