Query: Unified Growth Theory: A puzzling collection of myths based on
  hyperbolic illusions   The Unified Growth Theory is a puzzling collection of myths based on
illusions created by hyperbolic distributions. Some of these myths are
discussed. The examination of data shows that the three stages of growth
(Malthusian Regime, Post-Malthusian Regime and Modern Growth Regime) did not
exist and that Industrial Revolution had no influence on the economic growth
and on the growth of human population. All elaborate explanations revolving
around phantom features created by hyperbolic illusions might be fascinating
but they are scientifically unacceptable and, consequently, they do not explain
the economic growth. The data clearly indicate that the economic growth was not
as complicated as described by the Unified Growth Theory but elegantly simple.
