I'm not sold on the idea that you need Web Components (and thus Polymer/React) to build or maintain a complex web app. I think that "complex" can mean a lot of different things. I know from experience that things like <canvas> and Web Workers are already showing a lot of promise by bringing multi-threaded processing to the browser for graphics- and other CPU-intensive operations. I'm also excited for WebRTC, the telephony APIs, WebGL, and other things. These things will help us build complex web apps. When it comes to code maintainability, there is no shortage of organizational frameworks (backbone, angular, etc.), utility libraries (jQuery, underscore, etc.). These are helping me build complex apps. What is Polymer doing for me? Allowing me to use Web Components and shadow DOM? Oh, how earth-shattering. No thanks.
