@Plinz are you using concepts of #Supervenience / #DownwardCausation in your work? They seem key to me.
The only real thing may be the evolution of the state vector of the universe. Notions like "mind" and "brain" are an attempt at local compression, they try to describe something like spirals in a Mandelbrot fractal. Are these spirals real? How are they related?pic.twitter.com/GUB704yQWC

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.
