Chapter 7 suggests that the principles of quantum information theory, implicitly at work, as I have argued, already in Heisenberg's discovery of quantum mechanics, may play a major role in the future of fundamental physics and principle thinking there. Heisenberg's work and quantum information theory also share their "technological" nature in the broad sense of technology, as considered in Chap. 2 (Sect. 2.5). Indeed, which is the main theme of this conclusion, the question of quantum information and "the question concerning technology," in Heidegger's famous phrase, are deeply interconnected and may even be seen as one and the same question. For, the physics of quantum information is also the physics of the relationships between experimental and mathematical technology. All technology is essentially linked to information. Indeed, technology may be best defined as the means of obtaining information about systems, in the case of quantum systems, in the RWR-principle-based interpretations, as the means of generating information (classical in nature) through the interaction between quantum systems and the technology of measuring instruments. In this way, this conclusion brings together all of the main themes and fundamental principles discussed in this book.
