Deeper Than Quantum Mechanics—David Deutsch’s New Theory of Reality

One of the world’s leading theorists has a new theory of everything. Its first result: a description of classical and quantum information linking them under the same theoretical umbrella for the first time
Constructor theory turns this approach on its head. Deutsch’s new fundamental principle is that all laws of physics are expressible entirely in terms of the physical transformations that are possible and those that are impossible.
In other words, the laws of physics do not tell you what is possible and impossible, they are the result of what is possible and impossible. So reasoning about the physical transformations that are possible and impossible leads to the laws of physics.
Instead, the principles function very much like the conservation of energy. The conservation of energy is not a mathematical truth but Deutsch and Marletto say it is deeper than the laws of physics that obey it. By this, they mean that any as-yet-undiscovered laws must also be expected to obey this conservation rule.
La dernière « théorie du tout » en date, j’y trouve une petite saveur « Grothendieckienne » (et platonicienne aussi) :)
L’article est pas génial (un peu le bazar), pour ceux que ça intéresse, il y a même un site dédié.
