Which proves that GDP forecasts especially on a global scale is bullshit.<p>Continuous growth is another idiotic concept with contradicts with fluctuating, co-evolutionary nature of vastly complex competitive ecosystems (multi-level host-parasite co-evolution).<p>The difficulty is the same as with forecasting weather in areas with unique microclimates - each tiny valley in Himalaya has its own. One has to monitor its unique conditions to find recurring patterns and constraints.<p>Global forecasts of wastly complex processes are bullshit and attempts to use avarages is bullshit too.<p>There are thousands niche microeconomies witchin every region in the wirld, each controlled by its own unique constraints and variables and influenced by some variables of neighborhooring and related niches, etc. There are also climate, sociological, political, cultural factors, etc.<p>All such complicated models are wrong. They, like myths and religions, have no connection to actual reality while being taken on faith by corresponding sectarians.
