The paired opposite to reductionism is called emergentism, and in recent years it has begun to gain an increasing number of advocates. In summary, it means that the whole is more than the sum of its parts. Unexpected behaviors and properties can emerge, even from simple well-understood parts, at high enough levels of organization… Some of the ways emergentists have proposed creating artificial intelligence include building or simulating artificial neural nets, or using quantum computers, which take advantage of wave-particle duality and superimposition to perform fuzzy logic. Others reject the entire idea of shortcuts to emulating human intelligence, in favor of simply duplicating the entire fine structure of the human brain in virtual form –something not possible today, but perhaps in the future.
