Complexity is definitely a barrier for Angular 2 where I work. We use Angular 1 almost exclusively for our existing applications, but are most likely going to be continuing to use Angular 1 and migrating towards React rather than learning Angular 2. We already began using Redux so it's a much easier transition for us. I absolutely agree with you on the use of appropriate abstractions. One of our UI developers is a huge FP advocate and wrote large portions of our biggest frontend codebase using Ramda, and its basically incomprehensible to the majority of our engineers. I even though it was cool to begin with, but seeing the shape its taken at scale I regret it 100%.
