"Scientists have already reverse-engineered two dozen of the several hundred regions of the human brain; well understand its principles of operation and be in a position to re-create its powers in synthetic substrates well within 30 years. But we wont program human intelligence link by link in some massive expert system. Nor will we simply set up a single genetic algorithm and have intelligence at human levels automatically evolve itself. Rather, we will set up an intricate hierarchy of self-organizing systems, based largely on the reverse-engineering of the human brain, and then provide the computer entity with an education, which, given the increasing power of machines, can proceed hundreds if not thousands of times faster than the comparable process for humans."
