The notion of trying to manage risk, chaos, or anything with an underlying probabilistic driving process is futile. But attempts to reduce complexity or chaos. Or reduce risk, without understanding the underlying probabilistic driving processes is also futile.
Blanket statement about reducing complexity that don't state how this complexity will be reduced, or how the underlying probabilistic drivers will be altered is futile, or worse nonsense. The naive and populist notion that complexity simply emerges in the absence of the equations of motion for that complexity is the start is the problem of managing in the presence of complexity and managing in the presence of uncertainty.
So when you hear someone say the world is too complex, we need to reduce the complexity, ask what are the units of measure of the complexity, what are the driving functions for this complexity, what are the equations of motion exhibited by these driving functions, and how would these be changed to reduce the complexity.
