Not sure much has been learned..........

Elites today have no idea how to speak to the public, or what to say to it.  They have shown little interest in trying.  The hyper-educated individuals who ran the Clinton campaign were utterly indifferent to public opinion:  they believed in big data.  An algorithm nicknamed "Ada" delivered "simulations" of opinion to the campaign staff.  Ada was the public as elites wish it would be:  safe, clean, and speaking only when spoken to.  The voter in the flesh was clearly perceived by this group as an alien and frightening brute.  His very existence was deplorable.  The shock of election day followed naturally from such distortions of distance.
