I agree, React is fairly simple to use on it&#x27;s own, but the Flux pattern &#x2F; framework is really where the complexity comes in, IMO. I refer to them together b&#x2F;c you rarely see one without the other. My general feeling is, Flux seems like an excellent solution for some of the problems Facebook has -- their inbox for example, where you have multiple components on a page that need to react when external events happen (a message is sent, a message is received, etc). My feeling is that many would-be cargo-cult-ers don&#x27;t have problems at this level of complexity. Most of them are doing basic CRUD operations, and using a needlessly complex framework to do it.
