Complexity and emergence of cognition

With the development of cognitive computing the next generation of future computing paradigms will be related to interesting issue of emergence of the new functionalities that results from increasing complexity of systems. The fundamental question is; at what level of complexity, and why at that level, a given functionality is accessible? And, an another specific question can be asked; is there the need to make observation in time or conclusion about the specific functionality can be extracted from the static, read at one moment, information?
