From applied control theory I intuitively knew that a cascade of issues resulting in a system instability had overwhelmed the pilots. I now see this arrogance of data science based software engineering being inserted into business, industry and social systems. As an abstract example Facebook's attempt to stabilize the politics on its platform through algorithms. More concretely in the hydro dam control systems in the Pacific Northwest. Specifically in this damned Boeing 737 Max control system. Control systems need rigorous testing through simulation not accidents.
