They talk about Global Warming, negative interest rates, Brexit, etc. but the real threat is not in those specifics. The real threat lies in COMPLEXITY.
For evolutionary reasons, human mind is not prepared for complexity. When facing the unknown, we arewired to fight or run away . But survival is no longer based on this 2 paradigms. Its increasingly based in coping with complexity, in managing complexity.
The risk lies in between a decreasing quality of people in charge, and an exponentially increasing complexity of the system. And this is relevant not just or big organizations but also for the economy as a whole, and also for individuals.
At some point complexity surpasses the capability of elites to have a clear understanding of the World. From there, all decisions are just thumb guesses, and the system is basically like a plane flying without a qualified pilot. Collapse becomes almost inevitable.
