There is a huge difference between knowledge and knowledge. The one and artificial spread is programmed knowledge for the mind, here you find the ideas like making war for peace or poison your whole body to resist some ill. The other is the field, a connection to all available wisdom and knowledge through subconscious.
For every kind of control agenda you only need and want to have the first one. Well programmed follower and minions to turn humans to your capital in a better form of slavery, But you need to fight the second method, they should not be connected to a field of knowledge, should not look at the man behind the curtain.
That’s what you see in the world, where we all are part from. For future we will see A.I. to fulfill the controller parts, to rule the minions with well known methods that can be adapted to a computer routine very easy.
