Knowledge is seen as dangerous by people holding power over others. It always has been (e.g. the apple thing). Therefore, in an age where knowledge is more readily accessible to a much larger number of people, it behoves the groups in power to somehow thwart its development. A good way of accomplishing this is to use mass media to make the signal to noise ratio as small as possible. Which is itself accomplished nicely by paid, conscious, agents and amplified by the growing hordes of individuals humiliated, rather than motivated, by their lack of knowledge. The true becomes a moment of the false, the real a moment of the fake. I believe that "spaces", real or virtual, rather than techniques will develop for knowledge to flow and grow.
