Basically, we are in some kind of technological singularity, at least for most people. Humans on average are no longer smart enough to understand and cope with the technological developments around them.

Even if you knew everything that was going on (as Snowden largely did), and you could prove that it's evil, most humans don't have the intellectual skills required to understand it, no matter how calmly and clearly you try to explain it. It's beyond their ability to understand.
