^A computer that can digest and link together scientific
  literature from across different sciences - makes you think:

  word pattern matching between disciplines could definitely yield
  some fasctinating results. If you're looking up apples, a smart
  AI system should be able to link together facts and findings
  about the apple - nutritional science has the chemical breakdown
  of the apple, which can link to chemistry which has the
  properties of the elements and compounds which could lead to a
  medical database of the deficiency and excess of each of the
  chemicals on the human body... which mixes with hospital reports
  showing definiciencies and excesses of these compounds in the
  body... and it may develop a hypothesis that that "An Apple A
  Day keeps the Doctor Away'.^
