So theoretically, if one made mass profiles on individual users via telecommunications data, for instance, using cell towers one could seperate individuals on a spectrum of information. By directing cell traffic to specific servers. Put the angry with the angry. Put the suicidal with the suicidal. Even seperate by tax bracket if one wanted. Control the rate of dissemination of any kind of information. Who sees what. When they see it.
You could even craft a narrative for one to follow.
Because now there is machine learning,
And that makes all of this possible.
Obviously, this would have to be done internally by each respective company.
Unless one had a backdoor or "pass-through."
