  The unclear development direction of human society is a deep reason for that
it is difficult to form a uniform ethical standard for human society and
artificial intelligence. Since the 21st century, the latest advances in the
Internet, brain science and artificial intelligence have brought new
inspiration to the research on the development direction of human society.
Through the study of the Internet brain model, AI IQ evaluation, and the
evolution of the brain, this paper proposes that the evolution of population
knowledge base is the key for judging the development direction of human
society, thereby discussing the standards and norms for the construction of
artificial intelligence ethics.
