The Complexity Demon
Imagine a computer made of atoms. Since information flow† from atom to atom cannot exceed speed of light, there is a limit to its computing power.† According to Bremermann No material system whether artificial or living can compute more than 2 x 10e47 bits per second and per gram of its mass.† http://pespmc1.vub.ac.be/ASC/BREMER_LIMIT.html
Many similar demons dwell in our conceptual world which might be called complexity demons. Like the notion that the universe is a computer, and we are its computations.† Or the universal computer mentioned in Wolframís book, whose universality is compromised by Bremerannís limit. We may therefore distinguish between two kinds of complexity. One which can be generated with NKS, and a complexity demon which cannot.
Now imagine that life on earth is a computer, and† its processes are computations. Apparently life is also constrained by Bremermannís limit since it †does not generate its complexity from scratch. It starts its computations from a baseline, the complexity of a cell. †This issue was discussed in a another section
