After using Mobx for a few weeks, I've come to question why anybody would use anything else. It is the only software I've ever used that was created for a dynamic language that has me trying to re-implement in my favored strong/static typed languages. Now I just point and laugh at anybody trying to make sense of their Redux global state atom with a bajillion reducers.
So far, I've only found one common objection to it: that it embraces mutable state. Well duh...UIs are state machines. They need mutable state because their entire existence depends on it. Sure, you might be able to model the mutable state of UIs using immutable data structures, but you can't get rid of the mutable state. And because of this, my opinion of this objection is that it is of a religious nature. You can ignore this particular objection with no risk at all.
