**Complexity spectrum
**

In his book Wolfram talks of “The complexity”, while there may be many kinds of complexity. Since Life does not generate complexity from scratch we ought to distinguish between two kinds of complexity: NKS complexity, which can be generated with simple programs, and that of a cell, which cannot.

True, rules 30 and 110 generate immense complex patters, still it does not indicate that their complexity matches that of a living cell. One wonders how universal is Wolfram’s computer if it fails to emulate the complexity of a living cell? Or might his universal computer be only a conjecture?
