I don't believe in the notion that all technology that is the most beneficial and helpful to mankind is promoted to the masses. That is one of the reasons I go down rabbit holes. Not just technology, but in other subjects as well, such as accepted history, for example. Sometimes I find something interesting, sometimes I find a dead end.
Occulting (which means - hiding) information is important to special interests that don't want to see their monopolies threatened. Most people assume the opposite. They think that if X was a good tech, why isn't everyone using it. I had this conversation with a relative recently, and he asked me "if X can do that, why isn't everyone doing it?" He basically assumed that the media sources he listens to would of course inform him about it and that the masses are correct.
