Complex problems are not solved (only) with money". Original quote: "I — Alessandro Magnoli Bocchi

"Every day, 1) ‘simple systems’ become complex: for example, a village becomes part of a city; and 2) ‘complex systems’ become more complex: for instance, financial markets embrace machine learning. Often, an increase in complexity leads to unintended consequences"."

"The future is not a straight-line-projection of the past. Yet, most people - even scientists - think in linear, cause-effect patterns. The real world works differently: events follow discontinuous random walks, not predictable trends. At best, we can only assess the ‘likelihood of forthcoming events’. A rule-based approach is often misleading; to forecast future developments, we need probabilistic - rather than deterministic – thinking"."

"In an era of complexity, quantum thinking is needed – particularly in central banking"."

"We need to learn how to manage ‘non-linear feedback loops’, ‘quantum jumps’, and the unpredictable consequences any event can bring about"."

"Enlightened, quantum policymaking has an important role to play. Yet, ‘classical physics’ still shapes our way of learning. Cause-effect, linear thinking should be abandoned. To better understand our complex world, we must say “Bye” to Newton"."

"By nature, ‘complex systems’ grow or decay at exponential rates. As suggested by the butterfly-effect in chaos theory, a negligible change in an ‘original state’ can lead to a radically different ‘resulting state’. In other words, a minor event might have large, unpredictable effects - depending on its: a) position in network (i.e.: initial conditions); b) degree of connectivity (i.e.: ease of interaction); and c) size of the impact"."
