“Only a faster-than-exponential stock market growth makes private investors feel richer.”

Didier Sornette

Source: Why Stock Markets Crash - Critical Events in Complex Systems (2003), Chapter 10, 2050: The End Of The Growth Era?, p. 375
Contexte: In order to have a continuing influence, the stock market has to continue rising at an accelerating pace faster than exponential. Only a faster-than-exponential stock market growth makes private investors feel richer.

“Thus the so-called Moore's law is incorrect, since it implies only an exponential growth.”

Contexte: Faster-than-exponential growth also occurs in computing power, as measured by the evolution of the number of MIPS per $1,000 of computer from 1900 to 1997. Thus the so-called Moore's law is incorrect, since it implies only an exponential growth. This faster than exponential acceleration has been argued to lead to a transition to a new era, around 2030, corresponding to the epoch when we will have the technological means to create superhuman intelligence.

“Perhaps the most profound synthesis of physical sciences came from the realization that everything could be understood from "conservation laws" and symmetry principals.”

“The problem is not that this optimistic view is wrong. By economic accounting, the optimistic view is mostly right.”

“The acceleration of the number of traders buying into the market in the inflating bubble captures the oft-quoted observation that bubbles are times when the "greater fool theory" applies.”

“The assumption of perfectly rational, maximizing behavior won out until recently in the art of modeling, not because it often reflects reality, but because it was useful.”

“The point is that humans are rarely at their best when they use rational reasoning.”

“The price of a stock is strongly influenced by the behavior of the traders in a nontrivial way.”

“One trader's move in the market can be interpreted by another trader as relevant additional information due to the uncertainty he faces.”

“Indeed, the financial world is such that any insight is almost immediately used to trade for a profit.”

“Knowledge is encoded in models. Models are synthetic sets of rules, and pictures, and algorithms providing us with useful representations of the world of our perceptions and of their patterns.”
