The role and importance of EM 4-vector potential extends beyond physics theory. It is conceptually connected with the concept of ether, biofield and qi.Instead of finding an "umbrella theory", we would benefit more from understanding all this knowledge as a Network of Theories, with correspondences and translations, and implications ... This is reminiscent of Topos Theory.At experimental and technological level, the Superconducting Quantum Computing area provides a valuable lesson.At the other level of complex biological systems, the theory of chakras, meridians and acupuncture incites to find a common framework, in the sense of Cybernetics, enriched with Quantum Computing (Hardware and software).An contribution to the EPR debate is included: time-sync needs supplemented by space-alignment.In conclusion matter defines and "follows" the QI flow as a "reference frame", in the spirit of General Relativity, but at a gauge theory connection level.
