Well, I thought you may not take my allusion to C++ kindly. Sorry. But why hide from the fact that the origins of your proposal lies in it? I understand that you are concerned about how traditional physicist may receive your idea and do not want it to be trivialized as 'programming'. In your place, rather than trying to veil this fact or taking an apologetic stance for infringing with CS into the physics' territory, I would simply adopt the straightforward stance based on the fact that the future of physics lies with CS.
I tried to find that quote from Prof. D'Ariano but now think that I must have read it elsewhere. That day I also read his 2011 essay, where he says, "Recovering the whole Physics as emergent from the quantum information processing is a large program: we need to build up a complete dictionary that translates all physical notions into information-theoretic words." Isn't this where you come in?
The idea that algorithm is mightier than equation is certainly not new. D'Ariano speaks openly about the value in translating traditionally 'physical' terms into a computer-programming language. Your shyness in this regard only weakens your position.
The other weakness is that you propose that "structure of ETS events allows a uniform treatment of all events in Nature, including physical, chemical, biological, and mental events" -- and then fail to demonstrate it on one simple, well-understood, familiar example and go with poorly understood duality and entanglement instead -?
Then you pose several intriguing questions but then leave a reader disappointed:
"This brings up the key questions: How can we plan an experimental verification of the ETS formalism? And in particular, how do we approach the verification of the structure of (instantiated) events for photons, electrons, etc.?"
