By a “superintelligence” we mean an intellect that is much smarter than the best human brains in practically every field, including scientific creativity, general wisdom and social skills. [...]
Entities such as companies or the scientific community are not superintelligences according to this definition. Although they can perform a number of tasks of which no individual human is capable, they are not intellects and there are many fields in which they perform much worse than a human brain—for example, you can’t have real-time conversation with “the scientific community”.
-- Nick Bostrom, “How long until superintelligence” (1997)
