The problem is how knowledge in managed in our society.

A central authority administering truth to the greater unwashed mass is the popular method.

And it seems to be built into us, to get our truth that way. Truth is what the authority tells us. Contriving truth yourself is generally considered a perversion.

So there's that inertia, keeping the knowledge management system stuck this way.

Maybe high-quality society-wide pervasive knowledge is impossible.
