> The relevant literature is famously contentious and obscure. I believe it will remain so until someone constructs, within the formalism of quantum mechanics, an “observer,” that is, a model entity whose states correspond to a recognizable caricature of conscious awareness … That is a formidable project, extending well-beyond what is conventionally considered physics Wilczek, 2006. Quoted in a paper[0] that I like for its thorough stab at actually specifically defining the observer. It’s a tough task indeed!
