Imagine what facebook, google, or amazon do behind the scenes and not let anyone know about. The employ so many smart people that I doubt they have not been trying their very best to centralize information so that they grow even bigger.
It is not uncommon for governments and corporations trying to brainwash people to maintain obedient followers. That has happened over centuries even before computers. Today due to advancement in technologies there are fewer and fewer people on the planet that controls majority of the worlds wealth. This has to be because in order to have kings there will always be slaves.
Like you say the change we see from crypto and platforms like steemit will grow inevitably. When there are too many slaves that think for themselves they will revolt. I hope I get to see that day in my life. To see how crypto becomes the norm. Thanks.
