On Wheeler's Quantum Circuit

The Meaning Circuit Hypothesis (MCH) is a synthesis of ideas providing John Wheeler’s outline of ultimate physics, which he fine-tuned over several decades from the 1970s onward. It is a ‘working hypothesis’ in which ‘existence is a ‘meaning circuit”’ that portrays the world as a “system self-synthesized by quantum networking.” It was strongly advocated by him for roughly two decades and since then has had an increasingly strong impact on the approach of many investigators of quantum theory; in particular, elements such as the quantum participator and ‘it from bit’ are now considered by others as candidate components of a foundation for quantum theory in which information is involved essentially. Therefore, it is worthy of review and critique.
