Preamble The emergence of machine intelligence during the second half of
the twentieth century is the most important development in the evolution
of this planet since the origin of life two to three thousand million
years ago. The emergence of machine intelligence within the matrix of
human society is analogous to the emergence, three billion years ago, of
complex, self-replicating molecules within the matrix of an energy-rich
molecular soup - the first step in the evolution of life. The emergence
of machine intelligence within a human social context has set into
motion irreversible processes which will lead to an evolutionary
discontinuity. Just as the emergence of "Life" represented a
qualitatively different form of organisation of matter and energy, so
will pure "Intelligence" represent a qualitatively different form of
organisation of matter, energy and life. The emergence of machine
intelligence presages the progression of the human species as we know
it, into a form which, at present, we would not recognise as "human". As
Forsyth and Naylor (1985) have pointed out: "Humanity has opened two
Pandora's boxes at the same time, one labelled genetic engineering, the
other labelled knowledge engineering. What we have let out is not
entirely clear, but it is reasonable to hazard a guess that it contains
the seeds of our successors".
