There is no quality control. Information arrives as fast and as hot as pizza, but the sauce and the cheese are often processed, lacking in flavor or nutrition. The sausage is plastic. The mushrooms are freeze-dried. It's hard to find the real thing these days as knowledge passes for understanding.

Virtual truth is really just info-glut masquerading as wisdom. Students sometimes learn to equate length with quality. The more the better. Pile up the evidence, the sources and the quotations. Collect the thinking of others.
