“A society becomes totalitarian when its structure becomes flagrantly artificial. That is when its ruling class has lost its function but succeeds in clinging to power by force or fraud.”
George Orwell
“Some economists, when thinking about long memory, are concerned that it undercuts the Efficient Market Hypothesis that prices fully reflect all relevant information; that the random walk is the best metaphor to describe such markets; and that you cannot beat such an unpredictable market. Well, the Efficient Market Hypothesis is no more than that, a hypothesis. Many a grand theory has died under the onslaught of real data.” Benoît B. Mandelbrot
