How often do you write hashtables? JSON serializers? Mutexes? HTTP clients? Transaction managers? Connection pools? In my last job as a mobile engineer I can claim that I wrote code all day, and that's true to a point, but most of that code is shepherding data from one format to another, using libraries that I didn't write, causing the UI (whose framework was written by someone else) to update. And you know what? It's still a hard and rewarding job! Having pieces to plumb together hasn't made our jobs easier or dumber, it's just raised the level of abstraction at which we work day-to-day.
