This Brief is an essay at the interface of philosophy and complexity
research, trying to inspire the reader with new ideas and new conceptual
developments of cellular automata. Going beyond the numerical
experiments of Steven Wolfram, it is argued that cellular automata must
be considered complex dynamical systems in their own right, requiring
appropriate analytical models in order to find precise answers and
predictions in the universe of cellular automata.
Indeed, eventually we have to ask whether cellular automata can be
considered models of the real world and, conversely, whether there are
limits to our modern approach of attributing the world, and the universe
for that matter, essentially a digital reality.
