Within this context, we can answer Lucinélio Chaves de Azevedo's question: "About media changes in different systems (capitalism and socialism): are there media changes in Cuba?"
In the case of Cuba, in particular, we have a Totalitarian Abandonment Zone, with a low rate of collective intelligence and, therefore, of prosperity.
So, to answer Lucinélio's question: there is some kind of media change in Cuba, but in a very precarious and controlled way, slower than in other Survival Zones.
