The author wants to emphasize that each theory involves creativity and technical power and has its virtues and advantages, and their existence is not in danger after the identifications are shown here; because, for example, being efficient versus powerful in one way in one theory might lead to an opposite comparison in other parts within the same theory, and it always good to have many perspectives (especially when they are unified).

Assuming each virtual theory works all the way, one should be able to use the identifications provided in the grand unifying picture in this article to view the methods, tricks, reasons or results of any other theories from the viewpoint of a given particular framework, and this should be beneficial, e.g. it might help solve his/her potential problems in new settings. Users of virtual theories will get a sense of unity and less overwhelmed. After various gluing methods (at least four distinct ways) get related in the future (maybe not possible to be related as perfectly as structures and perturbations of virtual theories in this article), each package will produce independent and yet agreeing/relatable results. Hopefully, eventually a common understanding of soundness of each virtual theory is reached, researchers
