@Plinz are you using concepts of #Supervenience / #DownwardCausation in your work? They seem key to me.
Eg., the relationship between hardware and software is quite complicated. They are different abstractions for describing overlapping regions of the fractal. They are mapped via a sequence of compression models (statistical physics, electrics, logic, automata, languages, code).

The fact that this chain of mental model holds enables our prediction that a change in software will lead to a particular pattern of changes in the physical world. But it is not a "real" thing: it is a relationship between models. The observables are always the same.

The heat generated by the computer, the business function served by the computer, are two examples of a reality that are slightly orthogonal to these. The boundaries are different. In interesting cases, the different models shouldn't so clearly map onto each other.
