 Not quite everyone.  See below.

 Yes, Imo had discovered placer mining, the technique that's used in panning
 for gold.  She has been called the Archimedes of the Macaques.

 Actually the adult males never picked up either potato-washing or placer
 mining.  That's why some primatologists refer to senior faculty members who
 can't quite pickup on word processing or posting to Usenet as "macaque
 males."
 
 There's a highly readable account of Imo in Carl Sagan's and Ann Druyan's
 _Shadows of Forgotten Ancestors_ with references to the technical
 literature.  Also, David Attenborough visits the monkeys of Koshima Island
 in the penultimate episode of _Life on Earth_.  Finally, about 2.5 years
 ago I had the opportunity to converse with a Japanese primatologist; my
 first question for him was whether the Koshima macaques were still washing
 their sweet potatoes, and his reply was that they were.
