Blockchains, AI, and the uncertain promise of calculated certainties

Every culture chooses its own approach and creates its own authority to provide answers to the uncertainties of human life in socety. Since God has become obsolete as the guarantor of our society, it is up to instances such as the State, the People or the Market and the corresponding institutions to act in a way that creates meaning and reduces uncertainty. In the face of worsening crises (climate, wars, representation...), however, these instances are also increasingly losing their binding power, effectiveness and legitimacy.
Increasingly, therefore, the focus lies on algorithmic-based technologies, which, due to their number-based approach, are seen as the more reliable supplier of answers to the most pressing questions of our time. Unlike in the case of the previously mentioned instances, here, at least it seems, belief in the validity of their statements is no longer necessary: rather, by resorting to ever more extensive amounts of data, social and individual life is calculated, predictable and correspondingly controllable. Moreover, in the same way - in the sense of technological solutionism - it should be possible to defuse the most pressing crises.Two technologies in particular come to the fore:
With blockchain technology, the last factor of uncertainty - the middleman legitimising transactions - is now eliminated: Via algorithmically controlled consensus and automation processes, the decentralised, transparent and unforgeable control and regulation of binary and social processes will become possible and a "more reliable truth than any truth we have ever seen" (Casey/Vigna) will be created.
With (General) Artificial Intelligence, an entity is supposed to emerge that, on the basis of extensive data and self-learning algorithms, can replace the human, i.e. fallible intellect, and - eradicating any uncertainties - calculate and answer the unanswerable questions of human life.
Against the backdrop of the recent French history of ideas, I will explore in my paper to what extent this is actually a new - safer - form of uncertainty reduction or not; in other words, I will pose the question to what extent blockchains and AI actually eliminate uncertainties or exacerbate existing uncertainties or create entirely new uncertainties.
