I am evaluating whether or not to use one of these state managers (vuex in my case) at the moment. I looked over the original facebook talk about flux and I am kind of getting the feeling that this is one of those solutions to a problem I don't want to ever have. It isn't about how complex your app is, but rather, how complex your organisation is.

A lot of these solutions, like static typing in non-performance areas, and so on, are about "how do we get this new engineer to start working on code that he has no idea about quickly". This problem only exists in large organisations and I personally don't think large organisations are very good at anything so don't care about those set of problems.

Basically it comes across as another "how do we hire large numbers of average programmers" problem and the facebook talk said exactly that. State managers, like dependency injection, just add another level of indirection that make your application harder to debug. You can no longer just follow a simple chain of methods, because everything disappears into the magic land of the state manager as soon as you start using (as the vuex example) store.commit("increment", 10); instead of actual methods and so on.
