Since we live in the age of information, is there any excuse for ignorance. Since so many people have the knowledge of the world in their pockets, then why are there still so many people that understand so little?
What is being discovered (especially by the NSA) is that there is too much information, and that no one can process it all.
The problem with information now is not discovering the truth, but wading through too much truth to discover what is significant. If we choose the wrong truth to focus on, we can still be ignorant.
