“…On the one hand, it has been shown that the global hyperbolic acceleration pattern of the last 4 billion years appears to have been produced endogenously by the second order positive feedback between the complexity of the global sociobiological system and the rate of its complexity growth: the more complex the global biosocial system, the less time it takes it to make the next complexity jump -thus, the more complex the global system was, the faster its complexity grew. It has been shown that when written mathematically, such a feedback produces precisely a hyperbolic acceleration effect (see, e.g., von Foerster et al, 1960;Taagepera, 1976Taagepera, , 1979Kremer, 1993;Kurzweil, 2001;Tsirel, 2004;Korotayev, 2005Korotayev, , 2006aKorotayev, , 2006bKorotayev, , 2007Korotayev, , 2013Korotayev, , 2018Korotayev, , 2020bKorotayev & Khaltourina, 2006;Korotayev et al, 2006aKorotayev et al, , 2006bMarkov & Korotayev, 2007, 2008Korotayev & S.
