Dear Mauro
This is an interesting essay, and I continue to be surprised (as you have been) about how similar, and yet different, our lines of thinking have been.
Your demolition of object is interesting. However, rather than allowing us to talk about existence of an object, an operationalist viewpoint only allows us to define an entity, such as an electron, in terms of what it does to our measurement apparatus. I do not know, nor can I know, what an electron is. I can only discern a pattern of influences that I can choose to call an electron.
I am confused by your statement . I am not sure what "pure information" is, nor am I sure how to distinguish "kinds" of information. In my way of thinking, information is something that constrains one's beliefs. In this sense, I am not sure how "quantum information" is different than "classical information". Indeed in the paper that Philip Goyal and I wrote, (http://www.mdpi.com/2073-8994/3/2/171 ), we rely on regular old probability theory to derive the Feynman path integral formulation of quantum mechanics. The difference that QM plays is that one uses amplitudes to assign priors.
It also seems that your quantum elements need to sit in some kind of array or lattice. How does this lattice come about? Can there be dislocations? Or is it perfect? If so, why? In my approach there is no such lattice. In the case where one imagines a special situation where two observer chains may agree on the lengths of each others' intervals one gets a Minkowski metric and so on (as discussed in my essay).
Now I do like the fact that you come up with a BCC lattice as being important. You may be interested in a paper by Bialnycki-Birula which did not appear in your references (PRD 49(12), 1994, pp 6920-6927). He *reverse engineers* a complex-valued cellular automaton that reproduces the Weyl and Dirac equations. I'd be interested in learning more about your approach to see how similar or different your findings are to his.
I myself have found BCC lattices to arise naturally when I rely on three pairs of observers. I have not put this in any of my papers yet, but this was presented in my slides from my 2012 APS talk (http://huginn.com/talks/knuth-aps12-final.pdf).
Another difference here is that your approach relies on a concept of energy and mass (as coupling). In my essay I try to get an understanding of what these quantities represent in terms of what electrons do.
I continue to be surprised at how our parallel our paths are given that our foundational ideas are so different. Perhaps we are both at a point where we realize that the object we are exploring is a mammal belonging to the genus Proboscidea.
