Oh wow, I remember watching that, it's crazy to revisit that talk after so many years.

Redux and Flow are somehow branded as alternatives to MVC, when they are precisely MVC (store=model, dispatcher/reducer=controller, etc). It seems that Facebook (and many others) implemented MVC very poorly and pretended to abandon it instead of admitting they just did it better on the next attempt.

If anything, the success of redux simply reinforces the fact that MVC is a very useful pattern for UI applications. But, it bothers me that newer developers might be persuaded by the anti-MVC branding.
