On artificial and human 'intelligence'.

Ryan Calo, Professor of law at Washington university, points out the difference between the thought processes of advanced robots with artificial intelligence, and those of humans.

A robot would view the image of a clown offering free hugs 

as positive and friendly

(Hugs = good; Free = good; Clown = good),

whereas people would almost certainly not be enthusiastic about hugging the clown,

because of all sorts of (especially modern) negative
and quite subtle cultural associations.
